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

   The primary language support is JavaScript, which can be challenging for teams with limited experience in this ecosystem.

2. 02

   Limited documentation and examples for complex use cases

   Official documentation lacks detailed guides on advanced configurations and integrations beyond basic setup scenarios.

3. 03

   Frequent breaking changes between versions

   Historical updates from v0.1 to v0.2 required significant rework of existing chain definitions, impacting stability for long-term projects.

4. 04

   Limited language support beyond JavaScript

   While there are community-supported SDKs in other languages like TypeScript, official support is primarily focused on JavaScript.

What it does well

• Real-time data streaming and synchronization

• Scalable architecture for handling high volumes of concurrent connections

• Event-driven communication model

• Supports multiple transports including WebSockets, SockJS, and HTTP long-polling
