Understanding: babel-preset-react-app

[sathishsoundharajan]

Hi,
Just for understanding purpose to check either i misunderstood or a bug.

In babel-preset-react-app package between this lines (https://github.com/facebookincubator/create-react-app/blob/master/packages/babel-preset-react-app/index.js#L56-L63) you are adding two react-plugins for development/test mode.

Now lines (https://github.com/facebookincubator/create-react-app/blob/master/packages/babel-preset-react-app/index.js#L80-L88) will add full babel-react-preset itself which contains those two packages as dependencies

Now can help me understand why we are adding separately once again on top ?

Thanks for the question @bboysathish! babel-preset-react does have those plugins as dependencies, but if you look at the source code, it does not enable them at the moment.

Here's a discussion in the Babel repository about adding them to the preset: babel/babel#4702

@fson Thanks for the info. Made a pull request to explain.
