API Gateway

Manages all other microservices, and exposes an API for frontend clients to use.

Goals of this project:

• Learn about microservices
• Learn about gRPC
• Be able to use this service along with other microservice (have an API Gateway, a frontend in React, and interact with a To-Dos service.

To-do:

• Expose a REST Server
• Add a validator external package
• Interact with other gRPC servers such as the Users gRPC, and the To-dos gRPC (microservices)
• Validate authorization tokens (JWTs) for protected endpoints.
• Add data from to-dos gRPC
• Refactor repeated code in middleware.

Overall project architecture

API Gateway

• REST API (returns in JSON)
• A client for all the gRPC microservices (reads all the gRPC services).
• Responsible for the interactions between all the microservices.

Users gRPC

• Manages the users in the architecture

To-dos gRPC

• Manages all the to-dos.
• Maybe will be used for note-taking as well.

Frontend

• In React, will only call and use data from the API Gateway.
