v0.1.1在 OpenClaw 上管理 Expo React Native 应用,支持创建应用、添加屏幕、本地网页预览及在 /home/patron/apps 内安全检查预览状态。
Installation
cancorteaw-app
Local Expo / React Native app builder runner for my OpenClaw server.
This skill is a controlled runner that only executes an allowlisted script:
/home/patron/apps/_bin/appctl
and that script is restricted to operate under:
/home/patron/apps/<project>.
What it does
This skill wraps appctl to provide a safe, repeatable workflow:
- Create a new Expo app scaffold under
/home/patron/apps/<name> - Add a screen file under
/home/patron/apps/<name>/app/<Screen>.tsx - Start a web preview (
expo start --web) bound to127.0.0.1on a chosen port - Check status of the preview process
Commands
1) Create a new app
Command:
- new <name>
Example:
- new demoapp
Result:
- Creates /home/patron/apps/demoapp
- Initializes git (best-effort)
- Uses npx create-expo-app in non-interactive mode
2) Add a screen
Command:
- add-screen <name> <screenName> <title>
Example:
- add-screen demoapp Settings "Settings"
Result:
- Writes: /home/patron/apps/demoapp/app/Settings.tsx
- Makes a git commit (best-effort)
3) Start web preview
Command:
- preview <name>
Environment:
- EXPO_PORT (optional): override preview port
Default: 19006
Example:
- preview demoapp
- EXPO_PORT=19010 preview demoapp
Result:
- Starts npx expo start --web --port <port>
- Writes logs to: /home/patron/apps/_logs/<name>.preview.log
- Writes pid to: /home/patron/apps/_state/<name>.pid
- Writes port to: /home/patron/apps/_state/<name>.port
4) Status
Command:
- status <name>
Example:
- status demoapp
Result: - Prints RUNNING with URL if process is alive - Otherwise prints STOPPED
Safety / Guardrails
- The runner is allowlisted: only
node,npm,npx,git,bash,python3can be invoked. - All project paths are constrained to
/home/patron/apps. - Preview binds to
127.0.0.1(loopback). Expose it externally only via explicit SSH tunnel if desired. - Telemetry is disabled for Expo in preview (
EXPO_NO_TELEMETRY=1).
Troubleshooting
- If
previewsays running but page doesn’t load: check the log file in/home/patron/apps/_logs/. - If a port is busy: set
EXPO_PORTto a free port and re-runpreview. - To stop preview:
kill $(cat /home/patron/apps/_state/<name>.pid)(if pid exists).
