This PR introduces an upgraded Realtime streams backend and SDK that makes streams more reliable (and resumable) with increased or the removal of limits. We've also improved the visibily of streams via the run dashboard.

Todo

New limits

View the below limits table for more details:

Limit Streams v1 Streams v2
Maximum stream length 2000 Unlimited
Number of active streams per run 5 Unlimited
Maximum streams per run 10 Unlimited
Maximum stream TTL 1 day 28 days
Maximum stream size 10MB 300 MiB

Additionally, previously only a single client stream could be sent to a Realtime stream. Now, you can send multiple client streams to a single Realtime stream.

These new limits only apply when using the new streams backend powered by S2, and must be enabled explicitly when triggering a run by setting the new unstable_v2RealtimeStreams future flag when configuring your trigger client (or alternatively you can set the TRIGGER_V2_REALTIME_STREAMS=1 environment variable in your backend code):

import { auth } from "@trigger.dev/sdk";

auth.configure({
  future: {
    unstable_v2RealtimeStreams: true,
  },
});

Reliability improvements

When appending to a stream, the backend will now reliably resume appending from the last chunk index if there is a lost connection. Additionally, we've improved the reliability of reading from a stream by automatically resuming failed reads from the last chunk index if there is a lost connection.

This means that both sides of the stream will be much more reliable and will not lose data even when faced with network issues or other disruptions.

SDK improvements

We've moved the stream logic into their own dedicated namespace in the SDK instead of being mixed in with the other metadata methods:

import { streams, metadata, task } from "@trigger.dev/sdk";

const myTask = task({
  id: "my-task",
  run: async (payload: { message: string }) => {
    const stream = // ... get a stream from somewhere
      // Before:
      await metadata.stream("my-stream", stream);

    // After:
    await streams.append("my-stream", stream);
  },
});

You can now append to a stream using the streams.append method, which returns a result that can be used to wait until the stream is complete:

import { streams, task } from "@trigger.dev/sdk";

const myTask = task({
  id: "my-task",
  run: async (payload: { message: string }) => {
    const myAIStream = // ... get a stream from somewhere

    const { stream, waitUntilComplete } = await streams.append("ai-stream", myAIStream);

    // A. Iterate over the stream which is an async iterable and a ReadableStream
    for await (const chunk of stream) {
      console.log(chunk);
    }

    // B. Wait until the stream is complete
    await waitUntilComplete();

    return {
      message: "Stream completed successfully",
    };
  },
});

When calling streams.append from inside a task, the stream is automatically associated with the current run. You can also optionally specify a target run ID to append to a stream on a different run:

import { streams, task } from "@trigger.dev/sdk";

const myTask = task({
  id: "my-task",
  run: async (payload: { message: string; otherRunId?: string }, { ctx }) => {
    const myAIStream = // ... get a stream from somewhere

    // Append to a stream on the root run
    const { stream, waitUntilComplete } = await streams.append("ai-stream", myAIStream, { target: ctx.run.rootTaskRunId });

    // Append to a stream on the parent run
    const { stream, waitUntilComplete } = await streams.append("ai-stream", myAIStream, { target: ctx.run.parentTaskRunId });

    // Append to a stream on another run by ID
    const { stream, waitUntilComplete } = await streams.append("ai-stream", myAIStream, { target: payload.otherRunId });
  },
});

This means that, if you specify a target run ID, you can append to a stream outside of a task:

import { streams } from "@trigger.dev/sdk";
import { openai } from "@ai-sdk/openai";
import {
  convertToModelMessages,
  streamText,
  UIMessage,
  createUIMessageStreamResponse,
} from "ai";

// Allow streaming responses up to 30 seconds
export const maxDuration = 30;

export async function POST(req: Request) {
  const { messages, runId }: { messages: UIMessage[]; runId: string } =
    await req.json();

  const result = streamText({
    model: openai("gpt-4.1"),
    system: "You are a helpful assistant.",
    messages: convertToModelMessages(messages),
  });

  const { stream } = await streams.append(
    "ai-stream",
    result.toUIMessageStream(),
    { target: runId }
  );

  return createUIMessageStreamResponse({
    stream,
  });
}

We've also added a new streams.read method to read from a stream:

import { streams } from "@trigger.dev/sdk";

const stream = await streams.read(runId, "my-stream");

for await (const chunk of stream) {
  console.log(chunk);
}

You can also specify a timeout and start index to read from:

import { streams } from "@trigger.dev/sdk";

const stream = await streams.read(runId, "my-stream", {
  timeoutInSeconds: 10, // Will stop the stream if no data is received within 10 seconds
  startIndex: 10, // Will start reading from the 10th chunk
});

Default stream

Runs also now have a "default" stream which means you can optionally skip specifying a stream key:

import { streams } from "@trigger.dev/sdk";

// Skip the stream key, uses the default run stream
const { stream } = await streams.append(
  result.toUIMessageStream(),
  { target: runId }
);

// Read from the default run stream
const readStream = await streams.read(runId);

New useRealtimeStream hook

We've added a new useRealtimeStream hook to subscribe to a stream by its run ID and optional stream key:

"use client";

import { useRealtimeStream } from "@trigger.dev/react-hooks";
import { Streamdown } from "streamdown";

export function Streams({ accessToken, runId, startIndex }: { accessToken: string; runId: string; startIndex?: number }) {
  // parts will be typed as `string[]`
  const { parts, error } = useRealtimeStream<string>(runId, "stream", {
    accessToken, // Pass in a public access token to authenticate the request
    onData: (data) => {
      console.log(data); // Optionally, you can listen to the data as it comes in
    },
    timeoutInSeconds: 600, // Will stop the stream if no data is received within 600 seconds (default is 60 seconds)
    startIndex, // Will start reading from the xth chunk if provided (default is 0)
    throttleInMs: 50, // Will throttle the stream updates to 50ms (default is 16ms)
  });

  if (error) return <div className="text-red-600 font-semibold">Error: {error.message}</div>;

  if (!parts) return <div className="text-gray-600">Loading...</div>;

  const stream = parts.join("");

  return (
    <div className="space-y-4">
      <div className="text-sm font-medium text-gray-700">
        <span className="font-semibold">Run:</span> {runId}
      </div>
      <div className="prose prose-sm max-w-none text-gray-900">
        <Streamdown isAnimating={true}>{stream}</Streamdown>
      </div>
    </div>
  );
}

Just like the previous new functions, you can skip specifying the stream key when using useRealtimeStream:

// Uses the default stream
const { parts, error } = useRealtimeStream<string>(runId);

Dashboard improvements

We're now surfacing streams in the runs dashboard that will allow you to view the stream data in real-time:

Walkthrough

Adds a realtime streams subsystem across backend, runtime, SDK, client, and UI. Introduces DB migrations and TaskRun fields (realtimeStreamsVersion, realtimeStreams), Redis and S2 stream implementations, StreamsWriterV1/V2 writers, a global stream instance selector, ApiClient streaming APIs/headers, a core realtimeStreams manager and noop manager, SDK streams.append/read APIs, frontend viewer and hooks, route updates for SSE/resume semantics, dev configs (nginx/toxiproxy), seed/script replacements, CLI worker wiring for stream managers, and comprehensive tests for writers and Redis. Also removes the relayRealtimeStreams relay module.

Estimated code review effort

🎯 5 (Critical) | ⏱️ ~120 minutes

  • Changes are cross-cutting and heterogeneous: infra, DB migrations, runtime services, core libraries, SDK, CLI, and frontend.
  • Pay extra attention to:
    • StreamsWriterV1 / StreamsWriterV2: buffering, resume-from-chunk, HEAD resume logic, retries/backoff, ordering, AbortSignal handling, and ring-buffer correctness.
    • RedisRealtimeStreams & S2RealtimeStreams: SSE formatting, ping/inactivity timeout, lastEventId/resumption, ingest metadata (clientId, chunk indices), Redis XREAD semantics and TTL handling.
    • getRealtimeStreamInstance selection logic and removal of relayRealtimeStreams: ensure all callers and fallbacks updated.
    • Database migrations and Prisma schema changes (NOT NULL default and TEXT[] additions) and their runtime propagation.
    • ApiClient / runStream / SSEStreamSubscription: header x-trigger-realtime-streams-version, fetchStream/createStream signatures, SSEStreamPart shape and retry behavior.
    • Core realtimeStreams manager, StandardRealtimeStreamsManager and Noop implementation: lifecycle, active streams tracking, wait/timeout behavior, and dynamic writer selection.
    • Frontend RealtimeStreamViewer, useRealtimeStream hook, routes: SSE subscription lifecycle, resume/startIndex, timeout header parsing, autoscroll and UI interactions.
    • CLI/worker wiring and wait-until semantics changes affecting orchestration.
    • New and updated tests (streamsWriterV1.test.ts, redisRealtimeStreams.test.ts, runStream tests): timing-sensitive assertions and assumptions about external services.

55-69: Remove unused features variable.

Since v3Enabled is now hardcoded to true, the features variable computed on line 55 is no longer used and should be removed.

Apply this diff to remove the dead code:

- const features = featuresForUrl(new URL(env.APP_ORIGIN));
-
  const organization = await prisma.organization.create({
    data: {
      title,
      slug: uniqueOrgSlug,
      companySize,
      maximumConcurrencyLimit: env.DEFAULT_ORG_EXECUTION_CONCURRENCY_LIMIT,
      members: {
        create: {
          userId: userId,
          role: "ADMIN",
        },
      },
      v3Enabled: true,
    },

30-30: Use env export instead of direct process.env access.

This line directly accesses process.env.BLOCKED_USERS, which violates the coding guideline for this file path.

As per coding guidelines

Update env.server.ts to include BLOCKED_USERS if needed, then access it via the env export:

- if (typeof process.env.BLOCKED_USERS === "string" && process.env.BLOCKED_USERS.includes(userId)) {
+ if (typeof env.BLOCKED_USERS === "string" && env.BLOCKED_USERS.includes(userId)) {

19-23: Fix type re-export ordering for Context (compile error risk).

export type { Context }; appears before the import type { Context } ..., which can fail. Prefer a direct re-export.

Apply this diff:

-export type { Context };
-
-import type { Context } from "./shared.js";
+export type { Context } from "./shared.js";

The new export * from "./streams.js"; is good.

318-328: Early return may break when value is a ReadableStream. Convert to AsyncIterable.

You cast value to AsyncIterable, but ReadableStream isn’t AsyncIterable. Wrap it to avoid runtime issues when runId is undefined.

Apply:

-    const $value = value as AsyncIterable<T>;
-
-    if (!this.runId) {
-      return $value;
-    }
+    const toAsyncIterable = (input: AsyncIterable<T> | ReadableStream<T>): AsyncIterable<T> => {
+      if (Symbol.asyncIterator in (input as any)) {
+        return input as AsyncIterable<T>;
+      }
+      const stream = input as ReadableStream<T>;
+      return {
+        async *[Symbol.asyncIterator]() {
+          const reader = stream.getReader();
+          try {
+            while (true) {
+              const { done, value } = await reader.read();
+              if (done) return;
+              yield value as T;
+            }
+          } finally {
+            try {
+              reader.releaseLock();
+            } catch {}
+          }
+        },
+      };
+    };
+
+    if (!this.runId) {
+      return toAsyncIterable(value);
+    }

If you already have a shared utility for this conversion, prefer importing it instead.

276-313: Ingest must split by newline to preserve chunk boundaries and correct chunkIndex

86-98: Fix SWR keying and reset completion when runId changes (prevents mixed/stale state).

  • Keys for run/error/complete omit runId, so switching runId within the same hook instance can mix states and suppress onComplete for subsequent runs.
  • Also reset hasCalledOnCompleteRef and complete when runId changes.

Apply:

-    [idKey, "complete"],
+  const { data: isComplete = false, mutate: setIsComplete } = useSWR<boolean>(
+    [idKey, runId, "complete"],
     null
   );

And add a small reset effect:

   const hasCalledOnCompleteRef = useRef(false);
+  useEffect(() => {
+    hasCalledOnCompleteRef.current = false;
+    setIsComplete(false);
+    setError(undefined);

-    [idKey, "error"],
+  const { data: error = undefined, mutate: setError } = useSWR<undefined | Error>(
+    [idKey, runId, "error"],
     null
   );

Reset when runId changes:

   const hasCalledOnCompleteRef = useRef(false);
+  useEffect(() => {
+    hasCalledOnCompleteRef.current = false;
+    setIsComplete(false);
+    // fresh buffer for new run

408-423: Key SWR caches by tag/batch to avoid cross-subscription bleed.

apps/webapp/app/assets/icons/SnakedArrowIcon.tsx (1)

1-20: Extract props type for consistency.

The component is well-structured and follows React best practices for icon components. Consider extracting the props definition to an explicit type to align with project conventions of using explicit types over inline definitions.

1-27: Consider aligning structure with MoveToTopIcon for consistency.

The implementation is clean and follows the coding guidelines. However, MoveToTopIcon includes a <g clipPath> wrapper and <defs> section that are absent here. While the clipPath appears unnecessary (it defines a 24×24 rectangle matching the viewBox, likely an SVG export artifact), the structural inconsistency between paired components could cause confusion.

Consider either:

  1. Adding the clipPath/defs to match MoveToTopIcon for consistency, or

342-342: Consider constraining realtimeStreamsVersion to valid values.

The field accepts any string, but the summary indicates specific values like "v1" (default) and "v2" are used to coordinate between Redis-based and S2-based streaming backends. Using a literal union would prevent invalid values and improve type safety.

Apply this diff to constrain the field to known versions:

-      realtimeStreamsVersion: z.string().optional(),
+      realtimeStreamsVersion: z.enum(["v1", "v2"]).optional(),

If additional versions are anticipated, consider defining a shared schema constant like RealtimeStreamsVersion that can be reused across the codebase.


342-342: Add documentation for realtimeStreamsVersion.

The field lacks a JSDoc comment explaining its purpose or valid values. Documenting this would help developers understand when and how to set this field.

Apply this diff to add documentation:

     z.object({
       traceContext: z.record(z.unknown()).optional(),
+      /** Specifies the realtime streaming infrastructure version. Defaults to "v1" (Redis-based). Use "v2" for S2-based streaming. */
       realtimeStreamsVersion: z.string().optional(),
     })

113-155: Harden readStream(): always close span; fix falsy startIndex check.

  • If apiClient.fetchStream() rejects before invoking callbacks, the span won’t end.
  • startIndex uses a falsy check, so 0 is ignored.

-  return await apiClient.fetchStream(runId, key, {
-    signal: options?.signal,
-    timeoutInSeconds: options?.timeoutInSeconds ?? 60,
-    lastEventId: options?.startIndex ? (options.startIndex - 1).toString() : undefined,
-    onComplete: () => {
-      span.end();
-    },
-    onError: (error) => {
-      span.recordException(error);
-      span.setStatus({ code: SpanStatusCode.ERROR });

+      lastEventId:
+        options?.startIndex != null ? (options.startIndex - 1).toString() : undefined,
+      onComplete: () => {
+        span.end();

1299-1308: Align public wrapper requestOptions types with internals (API parity).

Internals accept TriggerApiRequestOptions (with clientConfig), but public wrappers still type requestOptions as ApiRequestOptions:

  • triggerAndWait(...) (Lines 433-455)
  • batchTriggerAndWait(...) (Lines 481-492)

This prevents callers from passing clientConfig to those wrappers.

Apply these diffs:

-export function triggerAndWait<TTask extends AnyTask>(
+export function triggerAndWait<TTask extends AnyTask>(
   id: TaskIdentifier<TTask>,
   payload: TaskPayload<TTask>,
   options?: TriggerAndWaitOptions,
-  requestOptions?: ApiRequestOptions
+  requestOptions?: TriggerApiRequestOptions
 ): TaskRunPromise<TaskIdentifier<TTask>, TaskOutput<TTask>> {
 export async function batchTriggerAndWait<TTask extends AnyTask>(
   id: TaskIdentifier<TTask>,
   items: Array<BatchItem<TaskPayload<TTask>>>,
   options?: BatchTriggerAndWaitOptions,
-  requestOptions?: ApiRequestOptions
+  requestOptions?: TriggerApiRequestOptions
 ): Promise<BatchResult<TaskIdentifier<TTask>, TaskOutput<TTask>>> {

175-218: Retry scope and recursion.

retryCount is a class field shared across flushes; recursion re-enters flush() and adds more promises. Prefer local attempt counting with a loop to avoid cross-flush interference and deep recursion. Also consider a maxBatchSize to bound memory before flush.

Would you like me to draft a non-recursive, per-flush retry loop and an optional maxBatchSize option?

apps/webapp/app/services/realtime/types.ts (1)

3-7: All implementers and call sites have been updated; style preference (type over interface) remains valid.

Breaking changes verified:

  • S2RealtimeStreams and RedisRealtimeStreams both implement updated signatures with clientId, optional resumeFromChunk, and new getLastChunkIndex method
  • Routes and tests use streamResponse(request, runId, streamId, signal, options) correctly
  • SSE lastEventId mapping verified: "Last-Event-ID" header properly used across packages/core and implemented in s2realtimeStreams and redisRealtimeStreams

Style: Per guidelines, convert to type aliases:

-export interface StreamIngestor {
+export type StreamIngestor = {
   initializeStream(runId: string, streamId: string): Promise<{ responseHeaders?: Record<string, string> }>;
   ingestData(stream: ReadableStream<Uint8Array>, runId: string, streamId: string, clientId: string, resumeFromChunk?: number): Promise<Response>;
   getLastChunkIndex(runId: string, streamId: string, clientId: string): Promise<number>;

4-4: Prefer isomorphic Web Crypto API over Node.js crypto module.

The coding guidelines specify preferring isomorphic code over Node.js specific imports. Replace randomUUID from node:crypto with the Web Crypto API's crypto.randomUUID() which works in both Node.js and browser environments.

Apply this diff:

-import { randomUUID } from "node:crypto";
+// Use Web Crypto API (isomorphic)

Then update line 73:

-    const id = randomUUID();
+    const id = crypto.randomUUID();

Based on coding guidelines.


200-237: Remove unused method or clarify its purpose.

The s2ReadOnce method is defined but never called within this file. If it's intended for future use or external consumption, consider adding a comment explaining its purpose. Otherwise, remove it to avoid code clutter.

Additionally, line 213 contains a citation artifact ":contentReference[oaicite:9]{index=9}" that should be removed from the comment.

If the method is not needed, apply this diff:

-  private async s2ReadOnce(
-    stream: string,
-    opts: {
-      seq_num?: number;
-      timestamp?: number;

-  ): Promise<S2ReadResponse> {
-    // GET /v1/streams/{stream}/records?... (supports wait= for long-poll; linearizable reads). :contentReference[oaicite:9]{index=9}
-    const qs = new URLSearchParams();
-    if (opts.seq_num != null) qs.set("seq_num", String(opts.seq_num));
-    if (opts.timestamp != null) qs.set("timestamp", String(opts.timestamp));
-    if (opts.tail_offset != null) qs.set("tail_offset", String(opts.tail_offset));

-        Authorization: `Bearer ${this.token}`,
-        Accept: "application/json",

-    if (!res.ok) {
-      const text = await res.text().catch(() => "");
-      throw new Error(`S2 read failed: ${res.status} ${res.statusText} ${text}`);
-    }
-    return (await res.json()) as S2ReadResponse;
-  }

Or if keeping it, update the comment on line 213:

-    // GET /v1/streams/{stream}/records?... (supports wait= for long-poll; linearizable reads). :contentReference[oaicite:9]{index=9}
+    // GET /v1/streams/{stream}/records?... (supports wait= for long-poll; linearizable reads)

339-396: Plumbed realtimeStreamsVersion looks good; consider narrowing the type.

The propagation into TriggerParams and TaskRun.create is correct. To prevent typos at compile time, narrow TriggerParams.realtimeStreamsVersion to a string union (e.g., "v1" | "v2") and let Prisma’s default "v1" apply when undefined.

83-84: Avoid importing components from route modules; move RealtimeStreamViewer to shared component

Importing from another route binds route bundles together and risks subtle loader side effects. Extract RealtimeStreamViewer into a shared component (e.g., components/runs/RealtimeStreamViewer.tsx) and import from there.

packages/core/src/v3/waitUntil/manager.ts (1)

6-6: Constructor implements centralized timeout strategy.

The timeout is now stored at the instance level with a sensible default of 60 seconds, aligning with the PR's centralized timeout approach.

Consider adding validation for the timeout parameter to prevent unexpected behavior:

-  constructor(private timeoutInMs: number = 60_000) {}
+  constructor(private timeoutInMs: number = 60_000) {
+    if (timeoutInMs <= 0) {

387-402: Consider URL encoding the path parameters.

The runId and streamKey are inserted directly into the URL path. If these contain special characters, the URL could be malformed.

Apply this diff to add URL encoding:

-    const url = `${options?.baseUrl ?? this.baseUrl}/realtime/v1/streams/${runId}/${streamKey}`;
+    const url = `${options?.baseUrl ?? this.baseUrl}/realtime/v1/streams/${encodeURIComponent(runId)}/${encodeURIComponent(streamKey)}`;

742-757: Consider using Zod for metadata stream validation.

The type checking for metadata.$$streams is verbose and could be simplified with Zod validation, which is heavily used in packages/core per coding guidelines.

Define a schema at the top of the file:

import { z } from "zod";

const MetadataStreamsSchema = z.object({
  $$streams: z.array(z.string()).min(1),
});

Then simplify the function:

 function getStreamsFromRunShape(run: AnyRunShape): string[] {
-  const metadataStreams =
-    run.metadata &&
-    "$$streams" in run.metadata &&
-    Array.isArray(run.metadata.$$streams) &&
-    run.metadata.$$streams.length > 0 &&
-    run.metadata.$$streams.every((stream) => typeof stream === "string")
-      ? run.metadata.$$streams
-      : undefined;
+  if (run.metadata) {
+    const result = MetadataStreamsSchema.safeParse(run.metadata);
+    if (result.success) {
+      return result.data.$$streams;
+    }
+  }

-  if (metadataStreams) {
-    return metadataStreams;
-  }
-
   return run.realtimeStreams;
 }

121-147: Use the run’s configured version for HEAD; avoid header-driven selection.

HEAD with v2 will currently throw. Select the instance from the run’s version (and consider returning 501 for v2).

Add version to select and use it:

57-87: Potential duplication in realtimeStreams array.

Using push can add the same streamId multiple times.

Prefer a unique set semantics (e.g., read existing array, de-dup, then set), or enforce uniqueness at the db layer.

apps/webapp/app/services/realtime/redisRealtimeStreams.server.ts (3)

245-251: Add SSE-friendly headers (buffering/CORS/version).

237-241: Use structured logger in cleanup.

Avoid bare console in server code.

Apply:

-  await redis.quit().catch(console.error);
+  await redis.quit().catch((err) =>
+    (/* this */ self ?? { logger }).logger.error(
+      "[RedisRealtimeStreams][streamResponse] Error during cleanup",

Note: if self not in scope here, capture const log = this.logger; before and use it.


288-296: Avoid logging raw chunk data.

Raw payloads can be large/sensitive. Log size/indices instead.

Apply:

-        this.logger.debug("[RedisRealtimeStreams][ingestData] Writing chunk", {

packages/core/src/v3/waitUntil/types.ts (2)

3-3: Type signature refined for deferred promise timeout.

The updated signature now explicitly passes timeoutInMs to deferred promise functions, making the timeout contract clearer.


8-8: API change verified – all call sites properly updated.

All references to blockUntilSettled() in the codebase confirm the timeout parameter has been removed and call sites updated accordingly. The sole call site at packages/core/src/v3/workers/taskExecutor.ts:1099 correctly invokes the method with no arguments, matching the new interface signature.

packages/core/src/v3/waitUntil/manager.ts (1)

16-31: Implementation correctly uses instance-level timeout.

The refactored blockUntilSettled method properly uses the stored timeout for both deferred promise invocation (line 22) and the race timeout (line 27). Memory management is sound with promises being cleared after settlement.

packages/core/src/v3/apiClient/runStream.ts (8)

1-19: LGTM!

The import additions are appropriate for the streaming infrastructure enhancements. All imported modules are actively used in the file.


51-51: LGTM!

The realtimeStreams field addition aligns with the PR objectives for Streams 2.0.


156-179: LGTM!

The new types and interface changes provide a solid foundation for the enhanced streaming API with resume support and timeout handling.


202-213: LGTM!

The subscribe method correctly returns a ReadableStream and properly wires up the connection and cancellation logic.


344-375: LGTM!

The retry logic with exponential backoff is well-implemented, properly handles abort signals, and includes sensible max retry limits.


765-765: LGTM!

The radix parameter has been correctly added to parseInt, addressing the previous review comment.


759-771: LGTM!

The Redis stream ID parsing is correct with proper fallback handling and NaN checks.


590-590: LGTM!

The realtimeStreams field is correctly added with a safe fallback to an empty array.

apps/webapp/app/services/realtime/redisRealtimeStreams.server.ts (1)

50-81: LGTM on unified inactivity threshold and pings.

Threshold computed once and reused in both branches; periodic pings help keep connections alive.

Also applies to: 162-178

packages/core/src/v3/realtimeStreams/manager.ts (2)

76-86: Consider hoisting p-limit import to module or class level.

The dynamic import (await import("p-limit")).default on line 82 runs every time a v2 stream is appended. While module caching prevents repeated loads, hoisting the import to module initialization would eliminate the async overhead on each call.

Add at the top of the file after imports:

// Lazy-load p-limit once for all v2 streams
let pLimitPromise: Promise<typeof import("p-limit").default> | undefined;
function getPLimit() {
  if (!pLimitPromise) {
    pLimitPromise = import("p-limit").then(m => m.default);
  }
  return pLimitPromise;
}

Then on line 82:

-          limiter: (await import("p-limit")).default,
+          limiter: await getPLimit(),

175-200: Consider parseInt radix and v1 fallback logging.

Two minor improvements:

  1. Lines 197-198: Use explicit radix in parseInt for clarity and to prevent unexpected octal/hex interpretation.
  2. Lines 186-188: The silent fallback to v1 when headers are missing could mask server misconfiguration. Consider logging a warning.

Apply this diff:

   return {
     version: "v2",
     accessToken,
     basin,
-    flushIntervalMs: flushIntervalMs ? parseInt(flushIntervalMs) : undefined,
-    maxRetries: maxRetries ? parseInt(maxRetries) : undefined,
+    flushIntervalMs: flushIntervalMs ? parseInt(flushIntervalMs, 10) : undefined,
+    maxRetries: maxRetries ? parseInt(maxRetries, 10) : undefined,
   };

Optionally add logging at line 187:

   if (!accessToken || !basin) {
+    if (version === "v2") {
+      console.warn("V2 realtime stream headers missing, falling back to v1");
+    }
     return { version: "v1" };
   }

1-14: LGTM: Imports are clean and necessary.

All imports are used in the implementation.


16-26: LGTM: Set-based tracking prevents stream collisions.

The switch from Map to Set correctly addresses the previous key collision issue, allowing multiple concurrent streams with the same key.


28-30: LGTM: Simple state management methods.

Both reset() and hasActiveStreams() are implemented correctly.

Also applies to: 103-105


32-101: LGTM: append() logic is well-structured.

The method correctly:

  • Normalizes input sources (line 38) ✓
  • Resolves target run IDs with clear error messages (lines 40-46) ✓
  • Forwards server tuning parameters to v2 streams (lines 84-85) ✓
  • Tracks streams with proper cleanup (lines 88-93) ✓

Signal handling and dynamic import issues are addressed in separate comments.


107-140: LGTM: waitForAllStreams() correctly handles timeout and propagates errors.

The implementation properly:

  • Uses Promise.all so stream rejections propagate immediately
  • Detects timeout via sentinel pattern
  • Aborts active streams on timeout
  • Provides clear error messages

This correctly addresses the previous review feedback.


143-161: LGTM: getRunIdForOptions() handles all target resolution cases.

The target resolution logic correctly handles special values ("parent", "root", "self"), custom run IDs, and the default current run fallback.

1110-1132: Consider adding explicit return type for clarity.

The createStream method implementation is correct and follows the expected RESTful pattern. The method collects response headers which is useful for accessing stream metadata.

For improved code clarity and maintainability, consider adding an explicit return type:

  async createStream(
    runId: string,
    target: string,
    streamId: string,
    requestOptions?: ZodFetchOptions
- ) {
+ ): Promise<CreateStreamResponseBody & { headers: Record<string, string> }> {

17-17: LGTM: New imports and exports support streams v2 functionality.

The imports for CreateStreamResponseBody, SSEStreamSubscription, SSEStreamPart, ApiClientConfiguration, and getEnvVar are all appropriately used in the new streaming features. Re-exporting SSEStreamSubscription and SSEStreamPart properly exposes these types to API client consumers.

Also applies to: 73-73, 77-77, 89-90, 137-137, 147-147


133-135: LGTM: Future flags implementation is backward compatible.

The ApiClientFutureFlags type and its integration into the ApiClient constructor is well-designed. The optional parameter with a default empty object ensures backward compatibility, and the unstable_ prefix clearly communicates the experimental nature of the v2 realtime streams feature.

Also applies to: 159-159, 166-167, 173-173


1078-1108: LGTM: Stream transformation logic is correct with expected type limitations.

The fetchStream enhancements properly wire through new options (timeoutInSeconds, onComplete, onError, lastEventId) to the subscription factory. The transformation from SSEStreamPart to T extracts the chunk field as expected. Note that since SSEStreamPart.chunk is typed as unknown, this relies on the caller to ensure type correctness at runtime, which is acceptable for a generic streaming API.


120-120: No action required - the clientConfig field is properly used.

The clientConfig field is consumed by apiClientManager.clientOrThrow() which accepts it as an optional configuration parameter. The method uses it to override baseURL and accessToken settings. Multiple callsites in packages/trigger-sdk/src/v3/shared.ts pass requestOptions?.clientConfig to this method, and it's used by end-user code (e.g., in references/realtime-streams/src/app/actions.ts). The field has a clear, intentional purpose for configuration management.


1196-1204: Clarify the intent of multiple environment variable names for the v2 realtime streams feature.

The code supports four environment variable patterns (TRIGGER_V2_REALTIME_STREAMS and TRIGGER_REALTIME_STREAMS_V2, each with "1" or "true" values) alongside a programmatic flag. These appear intentional for an experimental feature (prefixed unstable_), but the multiple patterns suggest either:

  • A migration path that should be documented
  • Configuration flexibility that could be simplified

Consolidate to a single environment variable name unless active migration support or multiple deployment scenarios require the flexibility.

283-285: Validate batch data structure with Zod.

The type assertion remains unsafe and could cause runtime errors if the response format doesn't match expectations. As per coding guidelines, Zod validation should be used.

Apply this diff to add safe validation:

+
+const BatchDataSchema = z.object({

+    z.object({
+      body: z.string(),
+      seq_num: z.number(),
+      timestamp: z.number(),
+    })
+  ),
+});

Then update the transform:

              } else {
                if (chunk.event === "batch") {
-                  const data = safeParseJSON(chunk.data) as {
-                    records: Array<{ body: string; seq_num: number; timestamp: number }>;
-                  };
+                  const parsed = safeParseJSON(chunk.data);
+                  const result = BatchDataSchema.safeParse(parsed);
+

501-521: Add error handling for stream subscription and processing.

The promise chain lacks error handling. If subscription.subscribe() rejects or stream processing fails, it will cause an unhandled promise rejection.

Apply this diff to add error handling:

                // Start stream processing in the background
                subscription.subscribe().then((stream) => {
                  stream
                    .pipeThrough(

                            chunk: chunk.chunk as TStreams[typeof streamKey],
                            run,
                          });

46-59: Fix Timeout-Seconds parsing to prevent NaN bypass.

The truthy check on line 47 allows NaN to slip through validation. When parseInt returns NaN, it's falsy, so the subsequent isNaN check on line 49 is skipped, and timeoutInSeconds becomes undefined. However, invalid inputs like non-numeric strings should be rejected with a 400 error.

Apply this fix:

-    const timeoutInSecondsRaw = request.headers.get("Timeout-Seconds") ?? undefined;
-    const timeoutInSeconds = timeoutInSecondsRaw ? parseInt(timeoutInSecondsRaw) : undefined;
-
-    if (timeoutInSeconds && isNaN(timeoutInSeconds)) {
-      return new Response("Invalid timeout seconds", { status: 400 });
-    }
-
-    if (timeoutInSeconds && timeoutInSeconds < 1) {
-      return new Response("Timeout seconds must be greater than 0", { status: 400 });
-    }
-
-    if (timeoutInSeconds && timeoutInSeconds > 600) {
-      return new Response("Timeout seconds must be less than 600", { status: 400 });
-    }
+    const timeoutInSecondsRaw = request.headers.get("Timeout-Seconds");
+    let timeoutInSeconds: number | undefined;
+    if (timeoutInSecondsRaw !== null) {
+      const n = Number(timeoutInSecondsRaw.trim());
+      if (!Number.isFinite(n)) {
+        return new Response("Invalid timeout seconds", { status: 400 });
+      }
+      if (n < 1) {
+        return new Response("Timeout seconds must be greater than 0", { status: 400 });
+      }
+      if (n > 600) {

96-106: Strengthen X-Resume-From-Chunk validation to reject fractional values.

The current validation checks isNaN(parsed) || parsed < 0, but doesn't verify the value is an integer. Fractional values like "5.7" will pass and could cause issues downstream.

Apply this fix:

       const resumeFromChunk = request.headers.get("X-Resume-From-Chunk");
       let resumeFromChunkNumber: number | undefined = undefined;
       if (resumeFromChunk) {
         const parsed = parseInt(resumeFromChunk, 10);
-        if (isNaN(parsed) || parsed < 0) {
+        if (!Number.isInteger(parsed) || parsed < 0) {
           return new Response(`Invalid X-Resume-From-Chunk header value: ${resumeFromChunk}`, {
             status: 400,
           });
         }
         resumeFromChunkNumber = parsed;
       }

88-116: Enforce v1-only for server-side ingest to prevent runtime errors.

The action path accepts X-Stream-Version from the client (line 90) and uses it to select the stream instance (line 108). When streamVersion is "v2", S2RealtimeStreams.ingestData will throw "S2 streams are written to S2 via the client, not from the server". It's better to fail fast with a clear 400 error.

Apply this fix:

       // Extract client ID from header, default to "default" if not provided
       const clientId = request.headers.get("X-Client-Id") || "default";
-      const streamVersion = request.headers.get("X-Stream-Version") || "v1";
+      const streamVersion = (request.headers.get("X-Stream-Version") || "v1").toLowerCase();
+      
+      if (streamVersion !== "v1") {
+        return new Response("Server-side ingest is only supported for v1 streams", { status: 400 });
+      }

       if (!request.body) {
         return new Response("No body provided", { status: 400 });
       }

       const resumeFromChunk = request.headers.get("X-Resume-From-Chunk");
       let resumeFromChunkNumber: number | undefined = undefined;
       if (resumeFromChunk) {
         const parsed = parseInt(resumeFromChunk, 10);
         if (!Number.isInteger(parsed) || parsed < 0) {
           return new Response(`Invalid X-Resume-From-Chunk header value: ${resumeFromChunk}`, {
             status: 400,
           });

60-62: Restore caller abort support when AbortSignal.any is unavailable.

33-47: Consider memoizing S2RealtimeStreams instances to reduce overhead.

A new S2RealtimeStreams instance is created on every call when streamVersion !== "v1". Since the instance holds connection state and configuration, recreating it repeatedly is inefficient.

const s2InstanceCache = new Map<string, S2RealtimeStreams>();

1146-1154: Reset RealtimeStreamViewer when stream changes

Switching between span entities that are both realtime-stream will reuse the same RealtimeStreamViewer instance, so the prior stream’s chunks, view mode, and scroll state linger until the hook tears down.

Learning: When using `assertExhaustive` in a `switch` statement in TypeScript (e.g., in the `shouldRetryError` function in `packages/core/src/v3/errors.ts`), and it throws an error, it's acceptable not to add a `return` statement afterward, as control flow will not proceed beyond the `assertExhaustive` call.

Learning: In modern PostgreSQL versions (11+), adding a column with a constant default value (like DEFAULT false, DEFAULT 0, DEFAULT 'text') does NOT require a table rewrite. PostgreSQL stores the default value in the catalog and applies it virtually when reading rows. Only non-constant defaults or more complex scenarios require table rewrites. Avoid suggesting multi-step migrations for simple constant defaults.

Prevent unhandled rejection from buffer task

When the source stream errors (or is aborted), startBuffering rethrows and the promise stored in bufferReaderTask rejects with nobody awaiting it, producing an unhandled rejection and leaving the request loop unaware of the failure. Capture the error, release the reader lock, and have the sender side fail fast so the task run doesn't crash later.

packages/core/src/v3/realtimeStreams/streamsWriterV1.ts lines 80-206: the buffer
task currently rethrows stream errors causing an unhandled rejection; instead
catch the error, record it to an instance field (e.g. this.bufferReaderError),
release the reader lock/close the reader (call this.streamReader!.releaseLock()
or this.streamReader!.cancel()), set streamComplete appropriately, and return
normally so bufferReaderTask resolves rather than rejects; then make the
request/sender path check this.bufferReaderError before/after awaiting buffered
data and fail fast (reject) with that error so the overall request loop observes
the failure and can cleanup (destroy request, stop retries).

455-455: Fix startIndex falsy check that drops lastEventId when startIndex is 0.

46-58: Fix Timeout-Seconds validation (truthy guard bug remains)

The truthy checks still let "0" and "NaN" slip through, so callers can request a zero-second timeout or send garbage and reach streamResponse, which breaks the promised 1–600 s bounds. Parse explicitly, enforce finiteness, and clamp the range before using it.

80-103: Stop buffer task rejections from leaking to the process

If the source stream errors (or the task aborts), the async IIFE rethrows the failure. Nothing awaits bufferReaderTask, so Node flags an unhandled rejection and the reader lock never gets released, leaving the sender loop spinning forever. Capture the error, release the reader, and let the send loop surface it so we can abort cleanly.

500-521: Handle subscription/pipe failures for stream fan-out

apps/webapp/app/models/organization.server.ts (1)

30-30: Environment variable access violates coding guidelines.

This line directly accesses process.env.BLOCKED_USERS instead of using the env export from app/env.server.ts. While this is existing code (not introduced in this PR), it should be refactored for consistency.

As per coding guidelines:

Apply this diff to align with the coding guidelines:

-  if (typeof process.env.BLOCKED_USERS === "string" && process.env.BLOCKED_USERS.includes(userId)) {
+  if (typeof env.BLOCKED_USERS === "string" && env.BLOCKED_USERS.includes(userId)) {

Note: Ensure BLOCKED_USERS is exported from ~/env.server.ts.

apps/webapp/app/routes/realtime.v1.streams.$runId.$target.$streamId.ts (1)

150-152: Remove unreachable null check.

The createLoaderApiRoute builder already validates that resource is non-null before invoking the handler (see apiBuilder.server.ts lines 185-195), so this null check is unreachable dead code.

Apply this diff to remove the dead code:

   async ({ request, params, resource: run, authentication }) => {
-    if (!run) {
-      return new Response("Run not found", { status: 404 });
-    }
-
     const targetId =
packages/core/src/v3/realtimeStreams/index.ts (1)

26-32: Consider explicit return type documentation.

The setGlobalManager and #getManager methods work correctly, but consider adding JSDoc comments to clarify the boolean return value from setGlobalManager indicates success/failure of registration.

+  /**
+   * Registers a global manager for realtime streams.
+   * @returns true if registration succeeded, false if a manager was already registered
+   */
   setGlobalManager(manager: RealtimeStreamsManager): boolean {
     return registerGlobal(API_NAME, manager);

Use TaskRun version instead of client-provided header.

The POST handler trusts the client-provided X-Stream-Version header to select the stream backend, but each TaskRun has an authoritative realtimeStreamsVersion field that should be used instead. Allowing clients to specify the version creates a mismatch risk where v2 data could be routed to a v1 run's stream (or vice versa).

The PUT handler demonstrates the correct pattern at lines 70-76 by using updatedRun.realtimeStreamsVersion.

Apply this diff after adding realtimeStreamsVersion to the query (see previous comment):

-      // Extract client ID from header, default to "default" if not provided
       const clientId = request.headers.get("X-Client-Id") || "default";
-      const streamVersion = request.headers.get("X-Stream-Version") || "v1";

Fetch realtimeStreamsVersion for loader.

The loader's TaskRun query doesn't select realtimeStreamsVersion, forcing the handler to trust the client-provided X-Stream-Version header (line 172). This creates the same version mismatch risk as in the action handler.

Use TaskRun version in loader.

Similar to the action handler, the loader should use run.realtimeStreamsVersion from the database rather than the client-provided X-Stream-Version header.

Verify all instantiation sites have been updated.

The constructor signature changed from accepting multiple parameters (apiClient, streamsBaseUrl, streamsVersion) to just ApiClient. Ensure all code that instantiates StandardMetadataManager has been updated to match the new signature.

Run the following script to find all instantiation sites:

The web search didn't help (returned unrelated metadata classes). Let me check the actual test file to see what the context is.

Fix test file instantiation to match updated constructor signature.

The test file at packages/core/test/standardMetadataManager.test.ts:35 still passes the old constructor arguments. Update it to remove the server.http.url().origin parameter:

-    manager = new StandardMetadataManager(apiClient, server.http.url().origin);
+    manager = new StandardMetadataManager(apiClient);

The CLI files were correctly updated; only the test file was missed.

now takes a single ApiClient parameter, but the test at

ApiClient (or its mock) consistent with the new constructor, and adjust any
setup/mocks or imports in the test to provide an ApiClient instance as before.

Verify no code paths are calling this deprecated method.

The fetchStream method now always throws a runtime error. This is a breaking behavior change that could cause failures if any code is still calling this method.

Run the following script to check for any remaining calls to this method:

Additionally, consider improving the error message to provide migration guidance:

-    throw new Error("This needs to use the new realtime streams API");
+    throw new Error(
+      "fetchStream has been deprecated. Use realtimeStreams.read(runId, streamKey, options) instead. " +
+      "See the realtime streams v2 documentation for migration details."

Verify if error message provides migration guidance.

This is a breaking change: the fetchStream method in manager throws an error, which propagates through the public wrapper API to active call sites. A call at packages/trigger-sdk/src/v3/metadata.ts:248 invokes runMetadata.fetchStream(key, signal), which delegates to the manager's throwing implementation.

The error message "This needs to use the new realtime streams API" lacks actionable migration details. To help developers transition, improve the error message:

-    throw new Error("This needs to use the new realtime streams API");
+    throw new Error(
+      "fetchStream is deprecated. Use the realtime streams v2 API instead. " +
+      "See migration guide: https://docs.trigger.dev/realtime-streams-v2"
+    );
🤖 Prompt for AI Agents
In packages/core/src/v3/runMetadata/manager.ts around lines 305 to 307, the
thrown Error("This needs to use the new realtime streams API") is too vague for
callers and breaks existing integrations; replace it with a clearer, actionable
error that tells developers what to use and how to migrate (e.g. reference the
new realtime streams API entry point, the new method name to call, and a short
example or link to docs), include the original key and suggestion to pass
AbortSignal to the new API, and consider using a specific Error subclass or
error code like "MigrationError: use realtimeStreams.fetchStream(key, signal) —
see docs: <doc-URL>" so callers can detect and handle the migration case
programmatically.

1026-1068: Fix startIndex handling to allow explicit 0 value.

Line 1043 uses startIndex ? ... which treats 0 as falsy. When a user explicitly passes startIndex: 0 to read from the beginning, this will be ignored and behave as if startIndex was undefined. This breaks the documented API behavior.

    const stream = await apiClient.fetchStream<TPart>(runId, streamKey, {
      signal: abortControllerRef.current?.signal,
      timeoutInSeconds,
-     lastEventId: startIndex ? (startIndex - 1).toString() : undefined,
+     lastEventId: startIndex != null ? (startIndex - 1).toString() : undefined,
    });

794-843: Extract specific option values to prevent unnecessary re-subscriptions.

Including the entire opts object in the dependency array (line 843) will cause triggerRequest to be recreated whenever opts is a new object reference—even if the actual values haven't changed. This is common when passing inline option objects (as shown in the JSDoc examples), and will cause the subscription to restart on every render.

Extract the specific values before the callbacks:

  const apiClient = useApiClient(opts);

1-14: LGTM!

Imports are comprehensive and correctly structured for the streams SDK module.


16-58: LGTM!

Type definitions are clear, well-documented, and provide appropriate flexibility for stream operations.


145-228: LGTM!

The append implementation correctly handles:

  • Overload parameter resolution
  • Span lifecycle management via instance.wait().finally()
  • Special AbortError handling (span ends without exception)
  • Comprehensive error recording for non-abort errors

233-255: LGTM!

ReadStreamOptions type is well-documented with clear defaults and appropriate configuration options.


333-354: LGTM!

Clean overload resolution and delegation to readStreamImpl. The pattern is consistent with the append function.


400-423: LGTM!

Clean namespace export and helper function. The getRunIdForOptions helper correctly resolves special target values ("parent", "root", "self") and provides appropriate fallback behavior.

packages/react-hooks/src/hooks/useRealtime.ts (4)

18-23: LGTM!

Clear documentation for the throttling parameter with appropriate default value.


291-291: LGTM!

Correctly applies the throttle parameter with the default value.


581-620: LGTM!

Type definitions are well-structured and comprehensively documented. The hook properly extends UseApiClientOptions to support authentication via access tokens.


622-752: LGTM!

Excellent API design with clear overloads and comprehensive documentation. The overload resolution cleanly handles both use cases.

⚠️ Potential issue | 🔴 Critical

Wrap fetchStream in try-catch to prevent span leak.

If apiClient.fetchStream throws before creating the stream (e.g., validation error, initial request failure), the span will never be ended since neither onComplete nor onError callbacks will be invoked. This causes span leaks.

Apply this diff to handle synchronous errors:

   const span = tracer.startSpan("streams.read()", {
     attributes: {
       key,
       runId,
       [SemanticInternalAttributes.ENTITY_TYPE]: "realtime-stream",
       [SemanticInternalAttributes.ENTITY_ID]: `${runId}:${key}`,
       [SemanticInternalAttributes.ENTITY_METADATA]: JSON.stringify({
         startIndex: options?.startIndex,
       }),
       [SemanticInternalAttributes.STYLE_ICON]: "streams",
       ...accessoryAttributes({
         items: [
           {
             text: key,
             variant: "normal",
           },
         ],
         style: "codepath",
       }),
     },
   });

-  return await apiClient.fetchStream(runId, key, {
-    signal: options?.signal,
-    timeoutInSeconds: options?.timeoutInSeconds ?? 60,
-    lastEventId: options?.startIndex ? (options.startIndex - 1).toString() : undefined,
-    onComplete: () => {
-      span.end();
-    },
-    onError: (error) => {
-      span.recordException(error);
-      span.setStatus({ code: SpanStatusCode.ERROR });
-      span.end();
-    },
-  });
+  try {
+    return await apiClient.fetchStream(runId, key, {
+      signal: options?.signal,
+      timeoutInSeconds: options?.timeoutInSeconds ?? 60,
+      lastEventId: options?.startIndex ? (options.startIndex - 1).toString() : undefined,
+      onComplete: () => {
+        span.end();
+      },
+      onError: (error) => {
+        span.recordException(error);
+        span.setStatus({ code: SpanStatusCode.ERROR });
+        span.end();
+      },
+    });
+  } catch (error) {
+    if (error instanceof Error && error.name === "AbortError") {
+      span.end();
+      throw error;

+    if (error instanceof Error || typeof error === "string") {
+      span.recordException(error);

+    }
+    
+    span.setStatus({ code: SpanStatusCode.ERROR });
+    span.end();
+    throw error;
+  }
 }

This also adds consistent AbortError handling with the append function.
