There is no github.io site for this project (no gh-pages branch).
https://www.npmjs.com/package/r2-shared-js
Command line install:
npm install r2-shared-js
OR
yarn add r2-shared-js
...or manually add in your package.json:
  "dependencies": {
    "r2-shared-js": "latest"
  }The JavaScript code distributed in the NPM package is usable as-is (no transpilation required), as it is automatically-generated from the TypeScript source.
Several ECMAScript flavours are provided out-of-the-box: ES5, ES6-2015, ES7-2016, ES8-2017:
https://unpkg.com/r2-shared-js/dist/
(alternatively, GitHub mirror with semantic-versioning release tags: https://github.com/edrlab/r2-shared-js-dist/tree/develop/dist/ )
The JavaScript code is not bundled, and it uses require() statement for imports (NodeJS style).
More information about NodeJS compatibility:
Note that web-browser Javascript is currently not supported (only NodeJS runtimes).
The type definitions (aka "typings") are included as *.d.ts files in ./node_modules/r2-shared-js/dist/**, so this package can be used directly in a TypeScript project.
Example usage:
// from index file
import { Publication } from "r2-shared-js/dist/es5/src";
// ES5 import (assuming node_modules/r2-shared-js/):
import { Publication } from "r2-shared-js/dist/es5/src/models/publication";
// ... or alternatively using a convenient path alias in the TypeScript config (+ WebPack etc.):
import { Publication } from "@r2-shared-js/models/publication";https://david-dm.org/readium/r2-shared-js
A package-lock.json is provided (modern NPM replacement for npm-shrinkwrap.json).
A yarn.lock file is currently not provided at the root of the source tree.
