I think we should consider doing this differently. Right now we don't have a guarantee that this identifier doesn't already exist (practically it probably won't matter but just in case…). We can use babel helpers to generate a unique identifier to use though and it'll be tracked on a per-file basis. This is how I did it for the object-assign transform: https://github.com/facebook/fbjs/blob/7c77c3c2ebcf0f1174512a66a08998dcff3d4cc5/babel-preset/plugins/object-assign.js#L15-L27

I think that all React* modules currently capitalized React...

The pattern is actually this:
- export an object or class? Upper case
- export a function? lower case
The only other one we have of the latter that starts with react is reactComponentExpect

I think this looks good other than my inlines. Can you post build size numbers? |
|
Yep, I wonder if there are things I can do to further reduce the size. It's much better than not rewriting invariant calls (leave them as-is) though. |
