useWebSocket Composable with Reconnection

Wrapping WebSocket in a composable, auto-reconnect with exponential backoff, status tracking.

Wrapping WebSockets in a Composable

Raw WebSocket handling scattered across components gets messy. A useWebSocket composable centralizes connection state, reconnection, and message handling — and you reuse it everywhere.

We will build it piece by piece.

Tracking Status with a Ref

Expose the connection state as a reactive status ref so the UI can show "Connecting", "Open", or "Closed" badges.

import { ref } from "vue"

export function useWebSocket(url) {
  const status = ref("CLOSED") // CONNECTING | OPEN | CLOSED
  // ...
  return { status }
}
