by React Native Example

studying-react-native-crud

Application developed as an assignment to college, subject Development for Mobile Devices, at UFPR, in order to learn building React Native applications. The project seeks to apply knowledge in functional components, screens navigation, Context API and reducers; This application is fully offline (no external data fetching).

The intent was to create a simple notes application with CRUD operations (create, read, update & delete) to explore the React API in mobile devices environment. We should have a screen to display a list of existing notes, feature to delete notes and features to see/edit new or existing notes in another screen. The state should be managed by React Context API and changes dispatched to a reducer.

Lessons Learned

  • Build a swipeable component;
  • React Native Navigation (stack mode);
  • React Context API (including useContext hook);
  • useReducer hooks to dispatch actions;
  • Babel plugin jsx-control-statements!!! AWESOME ?
