Android:
- in addition to capacitor dependencies, android ndk for stockfish compilation (to install with Android Studio).
Make sure you installed all deps:
$ npm install
Capacitor needs the web app before update, so build it:
$ npm run build
Update capacitor:
$ npx cap update
$ npm run serve
Will serve assets at http://localhost:8080
.
Once the server is running, browse to http://localhost:8080/www.
Be sure to Toggle Device Mode in your browser, or else you won't be able to click on anything.
The easiest way to do it is to open the native IDE. Capacitor has a command for that:
$ npx cap open
