Enable stage-0 Babel features on React Native.
npm install babel-preset-react-native-stage-0Have you encountered weird errors in React Native when trying to use babel-preset-react-native and babel-preset-stage-0 together? Are you generally just confused and frustrating by how hard it is to use the latest and greatest Babel features on RN? This preset is for you!
``bash`
npm install babel-preset-react-native-stage-0 --save
Just add a .babelrc file to your React Native project that looks like this:
`json5`
{
"presets": ["react-native-stage-0"]
}
Do you want/need experimental legacy decorator support (provided by babel-plugin-transform-decorators-legacy)? Use this as your .babelrc instead:
`json5`
{
"presets": ["react-native-stage-0/decorator-support"]
}
Q: I added stage-0 to my "presets" list, and now everything is broken!
A: Don't do that! This preset supersedes the need for including the stage-0 preset, and works properly with React Native.
---
Q: I changed my .babelrc to the above, but I'm still getting strange Babel errors!
A: Have you cleared your packager cache? Run the following:
`bash``
watchman watch-del-all
[the command you use to start the packager] --reset-cache
If things are still broken, open an issue and I'll try to help you. I may say "not a problem with this preset", and make you go open an issue on the react-native repo. Don't be mad at me if I do that!
