### Client
1. Build dev version (will include source maps):
> npm run dist:dev
2. Run from `dist` directory:
> npm run start
3. Use the browser's built-in developer tools or your favorite IDE.
### Node.js server
1. `npm run dist:dev`
2. `cd dist`
3. `node --inspect-brk ./index.js`
__HINT__: you might want to set `DEBUG` environment variable (see [debug](https://github.com/visionmedia/debug)):
> DEBUG=* node --inspect-brk ./index.js
### Android server (`scrcpy-server.jar`)
Source code is available [here](https://github.com/NetrisTV/scrcpy/tree/feature/websocket-server)
__HINT__: you might want to build a dev version.
To debug the server:
1. start node server
2. kill server from UI (click button with cross and PID number).
3. upload server package to a device:
> adb push server/build/outputs/apk/debug/server-debug.apk /data/local/tmp/scrcpy-server.jar
4. setup port forwarding:
> adb forward tcp:5005 tcp:5005
5. connect to device with adb shell:
> adb shell
6.1. for Android 8 and below run this in adb shell (single line):
> CLASSPATH=/data/local/tmp/scrcpy-server.jar app_process -agentlib:jdwp=transport=dt_socket,suspend=y,server=y,address=5005 / com.genymobile.scrcpy.Server 1.17-ws5 DEBUG web 8886
6.2. for Android 9 and above:
> CLASSPATH=/data/local/tmp/scrcpy-server.jar app_process -XjdwpProvider:internal -XjdwpOptions:transport=dt_socket,suspend=y,server=y,address=5005 / com.genymobile.scrcpy.Server 1.17-ws5 web DEBUG 8886
7. Open project (scrcpy, not ws-scrcpy) in Android Studio, create `Remote` Debug configuration with:
> Host: localhost, Port: 5005
Connect the debugger to the remote server on the device.
