support jest.config.mjs and jest.config.cjs #9225
Description
🚀 Feature Proposal
jest.config.js is using commonjs. Can we use jest.config.mjs and jest.config.cjs for config file in node 13.2?
Motivation
esm support for config file
Example
// jest.config.mjs
export default {
// [...]
// Replace `ts-jest` with the preset you want to use
// from the above list
preset: 'ts-jest/presets/js-with-ts',
};Pitch
Why does this feature belong in the Jest core platform?
Common feature proposals that do not typically make it to core:
- New matchers (see jest-extended)
- Changes to the default reporter (use custom reporters instead)
- Changes to node/jsdom test environments (use custom environments instead)
