Use these backend functions to subscribe to runs and streams from your server-side code or other tasks.

​
Overview

There are three main categories of functionality:
  • Subscribe functions - Subscribe to run updates using async iterators
  • Metadata - Update and subscribe to run metadata in real-time
  • Streams - Emit and consume real-time streaming data from your tasks

​
Authentication

All backend functions support both server-side and client-side authentication:
  • Server-side: Use your API key (automatically handled in tasks)
  • Client-side: Generate a Public Access Token with appropriate scopes
See our authentication guide for detailed information on creating and using tokens.

​
Quick example

Subscribe to a run: 
import { runs, tasks } from "@trigger.dev/sdk/v3";

// Trigger a task
const handle = await tasks.trigger("my-task", { some: "data" });

// Subscribe to real-time updates
for await (const run of runs.subscribeToRun(handle.id)) {
  console.log(`Run ${run.id} status: ${run.status}`);
}
