doc/contributors/extensions/dev-console.md
The dev-console extension provides a dev socket so you can run backend commands on a local Puter instance (e.g. commands registered in CommandService).
The extension is opt-in. Set the environment variable DEVCONSOLE=1 when starting Puter. The npm run dev script already does this:
npm run dev
With DEVCONSOLE=1, the extension registers a dev-socket service that creates a UNIX socket and runs command lines through CommandService.
See Backend – dev socket for how to connect (e.g. rlwrap nc -U ./dev.sock) and run commands like help, logs:indent, etc.
The extension lives in extensions/dev-console/. It only registers the dev-socket service when DEVCONSOLE=1; otherwise the extension loads but does nothing, so it does not affect default runs.
