Replay Node

Replay Node is an alpha Node.js runtime that records scripts so they can be replayed and inspected the same way as browser recordings.

Replay Node

Replay Node is built on Node 16 and is not under active development. It works for scripts that run on that version, but newer Node releases are not supported.

Basics

Replay Node applies the same recording approach as Replay Browser to Node.js. Recordings upload with the Replay CLI and open in Replay DevTools or through Replay MCP like any other recording.

1

Install Replay Node

Install the Replay Node package globally:

Terminal
npm i @replayio/node --global

Record your script

Use replay-node in the same way that you would use node to run your script:

Terminal
replay-node <script>
3

Upload your replay

Upload your recordings with the Replay CLI:

Terminal
replayio upload
4

View your replay

The CLI will upload your replays and provide you with a link to view them.

The following recording(s) will be uploaded:

 8a5ab266…  test.js    Now  31.0ms  Recorded
