I just updated to jest 24 and it seems like transformIgnorePatterns does not work.

this is the error I receive:

/Users/lemoustachiste/work/frontend/node_modules/my-untranspiled-package/build/bundle.js:7948
    export default Package$1;
    ^^^^^^
    SyntaxError: Unexpected token export
jest config:

  'modulePaths': [
    '<rootDir>/src/',
    '<rootDir>/node_modules'
  'transformIgnorePatterns': [
    'node_modules/(?!(my-untranspiled-package)/)'
  'transform': {
    '^.+\\.(ts|tsx)$': 'ts-jest',
    '^.+\\.(js|jsx)$': 'babel-jest',

The project is still configured for babel 6. It is working fine with Jest 23.
So I started by updating to babel 7 but still encountered the issue.
I then found this comment: https://github.com/facebook/jest/issues/7578#issuecomment-451671656
which pointed to this part of the docs: https://jestjs.io/docs/en/getting-started#using-babel
And sure enough, extracting the babel config to its own file out of the package.json fixed the issue.
