# tRPC - Subscriptions

Push live updates from your tRPC server to the client

## What this does

Your app needs to show things as they happen, not only when someone refreshes. This helps you stream events from a tRPC server, using server-sent events by default or WebSocket, recover missed events after a reconnect, keep connections alive with pings, and tidy up when a client leaves.

### Top 3 things it does for you

- Stream live events to the client
- Pick up where a dropped connection left off
- Keep an idle connection alive

## About tRPC - Subscriptions

This sets up real-time event streams with async generator subscriptions, written as .subscription(async function*() { yield }). SSE through httpSubscriptionLink is recommended over WebSocket.

It uses tracked(id, data) from @trpc/server for reconnection recovery with lastEventId. For WebSocket it covers wsLink and createWSClient from @trpc/client and applyWSSHandler from @trpc/server/adapters/ws.

It also configures SSE ping through initTRPC.create({ sse: { ping: { enabled, intervalMs } } }), uses AbortSignal via opts.signal for cleanup, and routes subscriptions with splitLink.
