Sello is an Android and iOS app for selling and buying used books. It fetches your location and profile (via Facebook API) and finds books for sale within a self choosen radius. After you find a seller/buyer you get connect via a chat to conclude your business! I made this on my spare time, on the side of my studies in computer science (2nd year).
This app was originally ment for students (on campus), since I thought new school books were (and still are) extremely expensive. Nevertheless, it will work for every type of books and could easily be extended to include different products.
It has never been easier to make an mobile application compatible on several platforms. In summary, I used:
- React Native
- Redux
- Expo
- Firebase
- Facebook API
- Small 3rd party libaries and native libaries to collect data (see package.json)
Firebase backend to handle
- Auth system
- Real-time response
And React native frontend.
