🎯 Choosing Between WebSocket and Socket.io: A Decision Every Dev Faces

Source: Dev.to

The Developer Pain

• WebSocket is elegant… until the real world walks in.
• Sudden network drops.
• You start with clean code and end up managing a rescue mission.

The Practical Developer Choice

• This is where Socket.io quietly becomes a lifesaver.
• Auto‑reconnects.
• Not perfect. Not the fastest.

When to Choose What

Go WebSocket when:

• You need the lowest possible latency and can handle connection edge‑cases yourself.
• Your environment guarantees stable network conditions.

Go Socket.io when:

• You want built‑in reconnection, fallback transports, and event‑based APIs.
• You prefer a higher‑level abstraction that handles many real‑world quirks.

The Dev Lesson

Real‑time systems aren’t about “what works in theory”. If your app touches real users, don’t choose based on purity alone.
