Development 🖥️

Formatting and Linting ✨

# Make sure no linting errors
npm run lint-err-only

# Make sure no TypeScript errors
npm run tsc-check

Building the App 🔨

Make sure to run npm install before trying the steps below!

Web Version

Building using this method for general development is highly recommended over the iOS and Android methods, it's much easier to debug and inspect changes. Running the app with iOS and Android simulators is only recommended to double-check that the changes you made are compatible with both platforms.

Start server:

npm run start

The app should then be available at http://localhost:5173/

iOS and Android Simulators (with Hot Reload)

If below doesn't work, check that network URL after displayed after running npm run start-exposed matches the URL in the capacitor.config.ts file

Start server in one terminal:

npm run start-exposed

Then run the script for the platform in another terminal:

iOS

npm run ios-live-reload

You can then select the type of iOS device you'd like to use as a simulator

To view debug info (inspect elements, view console output)

• If you've never done this before, you'll likely have to the make sure "Show features for web developers" is enabled under Safari's Settings

  

• Open Safari and click the iOS simulator for Hakubun under Develop -> iOS device you chose as simulator -> IP address displayed. If this is not displayed, make sure you followed the previous step. If it's still not displayed, opening Xcode can sometimes make it appear

  

Android

npm run android-live-reload

To view debug info (inspect elements, view console output)

• In Chrome, go to chrome://inspect/#devices

• An address should be available under "Remote Target", you can click on "inspect" to bring up a web inspector. This can be used to inspect elements and view console output

  

Testing
