Purple Train is a mobile app that provides schedules, predictions, and alerts for MBTA Commuter Rail riders.
The app is written in the elm language, using the experimental elm-native-ui library. See the Elm Native UI in Production blog post about why we are excited about writing mobile apps in elm.
- Make sure you have elm v0.18 installed
yarn run watch
This will start a watch server, which will recompile the elm files when they are saved.
We recommend using elm-format with your editor. You can set it up to format your Elm files when automatically saving them.
Running the app
yarn run start to start the react native packager, which will serve the
ios/PurpleTrain.xcodeproj and run the project to launch an iPhone
Follow the React Native Getting Started guide to create and run a virtual Android device.
See the CONTRIBUTING document. Thank you, contributors!
Updating elm packages for this project is more complicated than most. See DEPENDENCIES.md for detailed instructions.
