1. To build the JS and CSS files and start the configurator:
- With NW.js: Run `npm start`.
- With Chrome: Run `./node_modules/gulp/bin/gulp.js`. Then open `chrome://extensions`, enable
the `Developer mode`, click on the `Load unpacked extension...` button and select the `inav-configurator` directory.
Other tasks are also defined in `gulpfile.js`. To run a task, use `./node_modules/gulp/bin/gulp.js task-name`. Available ones are:
- **build**: Generate JS and CSS output files used by the configurator from their sources. It must be run whenever changes are made to any `.js` or `.css` files in order to have those changes appear
in the configurator. If new files are added, they must be included in `gulpfile.js`. See the comments at the top of `gulpfile.js` to learn how to do so. See also the `watch` task.
- **watch**: Watch JS and CSS sources for changes and run the `build` task whenever they're edited.
- **dist**: Create a distribution of the app (valid for packaging both as a Chrome app or a NW.js app)
in the `./dist/` directory.
- **release**: Create NW.js apps for each supported platform (win32, osx64 and linux64) in the `./apps`
This configurator is the only configurator with support for INAV specific features. It will likely require that you run the latest firmware on the flight controller.
If you are experiencing any problems please make sure you are running the [latest firmware version](https://github.com/iNavFlight/inav/releases).
Please note - the application will automatically update itself when new versions are released. Please ensure you maintain configuration backups as described in the INAV documentation.
