Logseq Electron Debug Skill

Use this when you need to inspect the Electron renderer (DOM, network, localStorage, Logseq APIs like logseq.api.*).

Prefer launching Electron from static/ (Electron Forge) instead of the root yarn dev-electron-app (gulp wrapper). The wrapper can be noisy and can surface false-negative exit codes even when the app launched.

Quick Start (Remote Debugging Port)

1. Ensure the dev app is built:

cd /Users/brz/repos/logseq
yarn watch

2. Start Electron with a remote debugging port:

cd /Users/brz/repos/logseq/static
yarn electron:dev -- -- --remote-debugging-port=9333

If you want to bypass Yarn and see the real command:

cd /Users/brz/repos/logseq/static
./node_modules/.bin/electron-forge start -- --remote-debugging-port=9333

3. Verify the port is live:

curl http://127.0.0.1:9333/json/list

4. Attach Chrome:

• Open chrome://inspect/#devices
• Add localhost:9333
• Click “inspect”

Common Pitfall: yarn dev-electron-app Does Not Forward Flags

yarn dev-electron-app runs via gulp electron, and it hard-calls yarn electron:dev without a way to pass through --remote-debugging-port=... unless you edit the gulp task (see /Users/brz/repos/logseq/gulpfile.js).

If you need a debug port, start via static/ as shown above.

Notes

• If a desktop Logseq instance is already running, quit it first. Electron single-instance behavior can make it look like flags were applied when they were not.
• Pick a port that is not in use (9333 is usually safe).
