Bundler doesn't import index.js if require is on a Directory

[boopathi]

- Project
  \ _ Component
       \ _ index.js
  \ _ App.js

App.js is the entry point

// App.js
var Component = require('./Component');

doesn't import index.js automatically. Had to manually specify

// App.js
var Component = require('./Component/index');

Thanks, we don't implement the full CommonJS spec. We use a different module format, where every module is declared via @providesModule in the docblock, see the example JS code:
https://github.com/facebook/react-native/blob/master/Examples/UIExplorer/SpinnerExample.js#L4

However, I'm aware that this is counter-intuitive for users, because we support part of the spec, namely, packages and relative imports in packages (mainly to be able to use npm modules). Anyways, I'll see if this feature can be safely added, otherwise, will make sure there is an options for users to use CommonJS instead of @providesModule

+1 for normal commonJS instead of the @provides docblock. The node version of commonJS and custom JS build scripts would be the best case scenario.

I actually forgot to close this issue. If lib is a dir with index.js require('./lib') will be the same as require('./lib/index.js').

And you don't have to use @providesModule. There are still differences from node modules and we'll work towards that, but I'm also happy to fix any differences you see in the near term

Actually, please don't use @providesModule. This is an internal convention that shouldn't be exposed to developers.
