mock-websocket-json-server

A json and WebSocket capable server, ideal for frontend development.

This is a base mock-server setup. Taking advantage of the fact that json-server is based on express, it is combined with the ws package to provide realtime capabilities while mocking.

This implementation utilizes:

1. Express
2. json-server
3. ws

• Start the simple (default) json-server with yarn serve:json. (more simplified codebase: 05ccaf08ceacca04476b0bebd05f384db8dabcf3) Run curl http://localhost:3000/transactions on a separate terminal to retrieve all transaction records.

• Start the fully capable custom websocket-json-server with yarn serve.

  • This script allows serving endpoint under a subpath, e.g. /api/,
  • as well as extend json-server functionality with custom logic (e.g. datetime filtering).
  • Add websocket capabilities on top of the custom server, under the subpath /feed.

Run curl http://localhost:4000/api/transactions on a separate terminal to retrieve all transaction records.

Or curl -X GET "http://127.0.0.1:4000/api/transactions/?datetime=2022-06-26T10:00:00Z" to retrieve transaction after the provided datetime.

Connect to the WebSocket on the endpoint ws://localhost:4000/feed.

Use a reverse proxy with TLS termination capabilities (e.g. NGinX, Caddy) to enable secure communications.

Note: Check out the json-server branch if you are not interested in WebSocket capabilities.

Note 2: Check the commit sequence to understand the required (followed) steps to setup this mock server.
