@svel/cli-plugin-babel

babel plugin for svelte-cli

Configuration

Uses Babel 7 + babel-loader + @svel/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 svelte.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 svelte.config.js.

Installing in an Already Created Project

vue add @svel/babel
