npm install
npm run dev # Start dev server on port 3000A Node peer that syncs over the relay without a browser — useful for backups or a long-lived sync node. It runs the same engine as the app, so it is end-to-end encrypted (keyhive) and identifies as one of your linked devices.
npm run cli -- accept-invite "<link>" # link this device (Settings -> Link Device in the app), then exit
npm run cli -- list # print every accessible document: id, versions, last-modified
npm run cli -- show <docId> [version] # render a document version as JSON to stdout (default: current)
npm run cli -- diff <docId> [from] [to] # print Automerge patch ops between two versions (default: latest change)
npm run cli -- sync # keep the recent docs open and sync continuously (Ctrl-C to stop)PORT- Server port (default 3000)AUTOMERGE_DATA_DIR- Persistent storage directory (default.data)NODE_ENV=production- Disables request logging, serves built frontend
