Package Exports
- babel-jest
- babel-jest/build/index
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (babel-jest) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
babel-jest
Usage
If you are already using jest-cli, add babel-jest and it will automatically compile JavaScript code using Babel.
yarn add --dev babel-jest @babel/coreIf you would like to write your own preprocessor, uninstall and delete babel-jest and set the config.transform 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. Typescript files are also supported.
"transform": {
"^.+\\.[t|j]sx?$": "babel-jest"
},
