* refactor: use babel.loadPartialConfigSync (added in babel 7.8) As planned in https://github.com/babel/babel/issues/10746, in babel 8 the old `loadPartialConfig` can't be used synchronously. * refactor: remove dependence on internal babel files, preparing for babel 8 See https://github.com/babel/babel/issues/10746 https://github.com/babel/babel/pull/10899
@vue/cli-plugin-babel
babel plugin for vue-cli
Configuration
Uses Babel 7 + babel-loader + @vue/babel-preset-app by default, but can be configured via babel.config.js to use any other Babel presets or plugins.
By default, babel-loader excludes files inside node_modules dependencies. If you wish to explicitly transpile a dependency module, you will need to add it to the transpileDependencies option in vue.config.js:
module.exports = {
transpileDependencies: [
// can be string or regex
'my-dep',
/other-dep/
]
}
Caching
cache-loader is enabled by default and cache is stored in <projectRoot>/node_modules/.cache/babel-loader.
Parallelization
thread-loader is enabled by default when the machine has more than 1 CPU cores. This can be turned off by setting parallel: false in vue.config.js.
Installing in an Already Created Project
vue add babel
