It's hard to contribute to native part of react-native for me. Of course tests are the most important, but do you consider adding linters too?
Linters also could distract and restrict too much. Now it looks like this:

react-native/React/Views/RCTNavItem.m:53:3: ivar assignment outside accessors or init P2
react-native/React/Modules/RCTUIManager.m:525:7: long variable name P3 Variable name with 21 characters is longer than the threshold of 20
react-native/React/Modules/RCTUIManager.m:1114:1: deep nested block P3 Block depth of 6 exceeds limit of 5
react-native/React/Modules/RCTUIManager.m:81:1: high npath complexity P2 NPath Complexity Number 258 exceeds limit of 200
react-native/Libraries/PushNotificationIOS/RCTPushNotificationManager.m:87:31: unused method parameter P3 The parameter 'application' is unused.
P1=0[0] P2=339[10] P3=545[20]

(P for Priority)

  • Add oclint and ocstyle (or write custom rules for oslint for consistent code styling conventions, sush as whitespaces, new lines, code blocks formatting, etc.).
  • Setup rules such as CODE_COMPLEXITY to avoid most of the current warnings and adopt linter to react-native conventions. Update code to Suppress OCLint Warnings.
  • Leave it as an option just for contributors and if it will work properly for a certain time then eventually add it to .travisci

Cool, would be great to have objC lint - not sure what the best option is though, so passing to Nick.

A bit of naive approach.
