This function subscribes to all changes to a run. It returns an async iterator that yields the run object whenever the run is updated. The iterator will complete when the run is finished.

​
Authentication

This function supports both server-side and client-side authentication. For server-side authentication, use your API key. For client-side authentication, you must generate a public access token with one of the following scopes:

  • read:runs
  • read:runs:<runId>

To generate a public access token, use the auth.createPublicToken function:

import { auth } from "@trigger.dev/sdk/v3";

// Somewhere in your backend code
const publicToken = await auth.createPublicToken({
  scopes: {
    read: {
      runs: ["run_1234"],
    },
  },
});
