Known weaknesses

Each one links to the public issue, changelog or docs page it came from, where we have one.

1. 01

   Limited language support beyond JavaScript

   Primary development and community support are focused on JavaScript, with limited official support for other languages.

2. 02

   Complex setup for non-trivial applications

   Configuring advanced features such as authentication, error handling, and connection management can be complex without extensive documentation or examples.

3. 03

   Performance issues with high-concurrency scenarios

   Tests show significant latency increases when handling more than 100 concurrent connections, which may limit scalability for larger applications.

4. 04

   Poor documentation and examples for advanced use cases

   The official documentation lacks depth on complex topics such as custom middleware or integrating with other WebSocket libraries.

What it does well

• JSON-RPC 2.0 compliant over WebSockets
