Inngest Realtime

When

Use when streaming durable workflow updates to a UI in real time — live order status, AI agent token streaming from a function to the browser, log tailing for long-running jobs, or human-in-the-loop approval flows. Covers Inngest v4 native realtime: typed channels, publishing from inside step.run, minting subscription tokens via server actions, and consuming the stream from React/Next.js. Do not install the v3-era @inngest/realtime package on inngest@4.
