Disable babel plugin on CircleCI

Question

I'd like to disable/not install one specific npm package in my app when CircleCI runs its tests, because the package makes the build process fail.

To be specific, it is a babel plugin for react-intl that automatically parses the files and pulls strings in another folder (babel-plugin-react-intl).

What is the best way of achieving this? Can this be done in the .babelrc file for example?

Answer 1

How you install and run tests locally should be the same as your CI setup.

If you need to disable a babel transform for tests - have them run as a different NODE_ENV and make sure your .babelrc only includes the plugin for the specific NODE_ENV eg:

{
  "env": {
    "production": {
      "plugins": ["react-intl"]
    }
  }
}

See: https://babeljs.io/docs/usage/babelrc/#env-option
