Use Socket.IO for chat applications, live collaboration, real-time dashboards, multiplayer games, or any feature where the server needs to push updates to clients. The automatic reconnection and room system make it production-ready out of the box.
Use TypeScript for any JavaScript project that will grow beyond a few hundred lines or be worked on by more than one person. The upfront cost of adding types pays back quickly in editor autocomplete, safe refactoring, and catching bugs before runtime.
Socket.IO's abstraction layer adds overhead — if you're communicating between services where you control both ends, raw WebSockets or Server-Sent Events (for one-way) are lighter. For very high throughput (millions of concurrent connections), the overhead of Socket.IO's protocol becomes meaningful.
TypeScript adds a compilation step and a learning curve. For tiny scripts, config files, or throwaway code, plain JavaScript is faster to write. TypeScript's type system also has limits — it can't track runtime behaviour, only the shape of values at compile time.
