Problem

(yep, that headline is overrused) Disclaimer: - I have no control over the website (socket.io), to my knowledge only @rauchg has, so I'm unfortunately not able to fix those issues: https://github.com/socketio/socket.io/issues/2807 https://github.com/socketio/socket.io/issues/2791 https://github.com/socketio/socket.io/issues/2781 https://github.com/socketio/socket.io/issues/2773 https://github.com/socketio/socket.io/issues/2753 https://github.com/socketio/socket.io/issues/2743 https://github.com/socketio/socket.io/issues/2736 - I have no control over the chat example repository, that is the one that is behind the chat example, so I'm unfortunately not able to fix those issues: https://github.com/socketio/socket.io/issues/2821 (and all open PR over there) - I'm not even an expert in Socket.IO, just a developer digging around during his free time between two freelance contracts Now, enough about my limitations. The Server API and Client API were added on Github, do not hesitate if you find something missing! Current to-do list: - [x] release the version `2.0` of Engine.IO Engine.IO will now default to uws as WebSocket engine, that should bring great performance improvements. An important issue about double UTF-8 encoding was also fixed in the parser. The only "problem" is that one of the numerous issues open could need a fix over there, hence the delay. - [ ] complete the API docs (missing methods, code examples...): https://github.com/socketio/socket.io/issues/2350#issuecomm

Enhance Socket.IO Performance with Updated API Documentation

Medium Risk

The Socket.IO library has performance issues and lacks comprehensive API documentation, which leads to inefficient usage and confusion among developers. The transition to Engine.IO version 2.0 with uws as the default WebSocket engine improves performance, but without clear documentation, developers may not utilize the library effectively.

Awaiting Verification

Be the first to verify this fix

  1. 1

    Update Engine.IO to Version 2.0

    Ensure that the latest version of Engine.IO is installed, which includes performance improvements and fixes for double UTF-8 encoding issues. This will enhance the overall performance of Socket.IO applications.

    bash
    npm install engine.io@2.0
  2. 2

    Review and Implement uws as WebSocket Engine

    Switch the WebSocket engine to uws for improved performance. This can be done by modifying the server setup to specify uws as the engine when initializing Socket.IO.

    javascript
    const io = require('socket.io')(server, { engine: { name: 'uws' } });
  3. 3

    Complete Missing API Documentation

    Contribute to the Socket.IO documentation by identifying and documenting missing methods and providing code examples. This will help developers understand how to use the library more effectively.

    markdown
    Refer to existing issues and PRs on GitHub to identify gaps in documentation.
  4. 4

    Test Performance Improvements

    Run performance benchmarks before and after implementing the changes to measure the improvements in latency and throughput. Use tools like Apache Benchmark or Artillery for testing.

    bash
    artillery quick --count 10 -n 20 http://localhost:3000
  5. 5

    Gather Feedback from Users

    Collect feedback from developers using the updated Socket.IO library to identify any remaining issues or areas for improvement. This can be done through surveys or GitHub discussions.

    markdown
    Create a survey form using Google Forms or similar tools.

Validation

Confirm that the performance benchmarks show improved latency and throughput after the updates. Additionally, check that the API documentation is complete and that developers report a better understanding and usage of the library.
