Run online
- Use the browser playground as the subscriber surface.
- Run the Node publisher locally against the same channel.
Run locally
- Run the Node publisher script with a valid API key.
- Subscribe from the browser playground on the same canonical channel.
Expected output
- The browser receives Node-published messages with the same payload shape defined by the shared scenario.
Troubleshooting
- If no events arrive, confirm both runtimes use the same channel and environment URLs.
Hybrid workflow
This page documents a local-to-browser bridge flow rather than a second hosted app. The browser subscriber lives in the instant demo, and the Node publisher lives in the repo script listed below.
