babel-jest

Babel jest plugin

Usage

If you are already using jest-cli, just add babel-jest and it will automatically compile JavaScript code using babel.

yarn add --dev babel-jest babel-core

Note: If you are using babel version 7 you have to install babel-jest with

> yarn add --dev babel-jest 'babel-core@^7.0.0-0' @babel/core
> ```

If you would like to write your own preprocessor, uninstall and delete babel-jest and set the [config.transform](https://jestjs.io/docs/configuration#transform-object-string-string) option to your preprocessor.

## Setup

_Note: this step is only required if you are using `babel-jest` with additional code preprocessors._

To explicitly define `babel-jest` as a transformer for your JavaScript code, map _.js_ files to the `babel-jest` module.

```json
"transform": {
  "^.+\\.jsx?$": "babel-jest"
},
