Doesn't work with React Native

[cooperka]

I got a very similar issue to https://github.com/4Catalyzer/babel-plugin-dev-expression/issues/2 using React Native v0.43. After some testing, it turns out this plugin doesn't work at all with React Native :(

Property property of MemberExpression expected node to be of a type ["Identifier"] but instead got "BinaryExpression"

.babelrc:

{
  "presets": ["react-native"],
  "plugins": ["dev-expression"]
}

Any idea what's going on or how to fix it?

Hmm, I think this is picking up on object keys that are __DEV__.

[jquense]

it does do that, i've had to do { '__DEV__': true } to trick it...

[taion]

yeahhhhh what do you think are the odds that they'll accept a PR to fix this upstream? or should we make this an actual fork instead of a copy/paste?
