Known weaknesses

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

1. 01

   Steep learning curve for non-JavaScript developers

   Kalm's low-level socket routing and middleware framework require a deep understanding of JavaScript and its asynchronous patterns.

2. 02

   Limited language support beyond JavaScript

   The primary development language is JavaScript, with limited official support for other languages, making it less accessible to polyglot teams.

3. 03

   Frequent breaking changes between versions

   Historical version updates have included significant API changes that required substantial refactoring in existing projects (v0.1 to v0.2 migration).

4. 04

   Complex setup and configuration for beginners

   Setting up Kalm requires detailed knowledge of network configurations, middleware chaining, and socket handling which can be overwhelming for new users.

What it does well

• Low-level socket routing capabilities

• Middleware framework for network communication
