Readme
This package includes the Babel preset used by Create React App.
Please refer to its documentation:
The easiest way to use this configuration is with Create React App, which includes it by default. You don’t need to install it separately in Create React App projects.
If you want to use this Babel preset in a project not built with Create React App, you can install it with the following steps.
First, install Babel.
Then install babel-preset-react-app.
npm install babel-preset-react-app --save-dev
Then create a file named .babelrc
with following contents in the root folder of your project:
{
"presets": ["react-app"]
}
This preset uses the useBuiltIns
option with transform-object-rest-spread and transform-react-jsx, which assumes that Object.assign
is available or polyfilled.
Make sure you have a .flowconfig
file at the root directory. You can also use the flow
option on .babelrc
:
{
"presets": [["react-app", { "flow": true, "typescript": false }]]
}
Make sure you have a tsconfig.json
file at the root directory. You can also use the typescript
option on .babelrc
:
{
"presets": [["react-app", { "flow": false, "typescript": true }]]
}
Absolute paths are enabled by default for imports. To use relative paths instead, set the absoluteRuntime
option in .babelrc
to false
:
{
"presets": [["react-app", { "absoluteRuntime": false }]]
}
