Realtime and Frontend

The full, version-pinned reference ships inside your installed @trigger.dev/sdk. Read it before writing code — it always matches the SDK version in this project, so it never drifts:

• Skill: node_modules/@trigger.dev/sdk/skills/trigger-realtime-and-frontend/SKILL.md — run subscriptions, @trigger.dev/react-hooks, streams, frontend triggering, and scoped tokens.
• Docs: the full, version-pinned docs ship bundled at node_modules/@trigger.dev/sdk/docs/realtime/; the skill above lists the exact pages it draws from in its sources: frontmatter. Grep for a hook, e.g. grep -rl "useRealtimeRun" node_modules/@trigger.dev/sdk/docs/.

If those paths don't exist, @trigger.dev/sdk isn't installed yet — install it first. In a non-hoisted layout, resolve the package with node -p "require.resolve('@trigger.dev/sdk/package.json')" and read skills/ + docs/ beside it.

Common mistakes

1. CRITICAL: Triggering from the browser with a Public Access Token. The read token from createPublicToken cannot trigger tasks.

   • Wrong: useTaskTrigger("my-task", { accessToken: publicAccessTokenFromCreatePublicToken })
   • Correct: mint a single-use Trigger Token with auth.createTriggerPublicToken("my-task") and pass that.

2. Token with no scopes. A scopeless token authorizes nothing, so every subscribe 403s.

   • Wrong: await auth.createPublicToken()
   • Correct: await auth.createPublicToken({ scopes: { read: { runs: ["run_1234"] } } })
