53. # react-native talk
- [x] deploying, fastlane
- [x] iOS test flight
- [x] android beta version (alpha, beta, production)
- [x] build via npm scripts
- [x] fastlane pushes all the way into the appstore, just need to click and release it
- [x] android builds just need to be uploaded
- [ ] tests run purely in node, makes it easy to separate react and JS
- [x] simulators
- [x] babelrc removal script
- [x] device specific: the group selector, is just different native UI
- [ ] sync+async architecture
- [ ] offline capability
- [x] debugging with chrome, even on the real device
- [ ] adb can be a saviour
- [ ] error reporting is kinda painful
- [x] GPS on mobile is no fun
- [x] use the rn docs
- [x] the API
- [x] the components
- [ ] as little number of dependencies as possible
