@snowpack/babel-plugin-package-import

Babel plugin to rewrite package imports from their package name to their resolved web_modules URL. Uses the import-map.json file contained in each web_modules/ directory to map each package.

npm install --save-dev @snowpack/babel-plugin-package-import

// babel.config.json / .babelrc
"plugins": [["@snowpack/babel-plugin-package-import", { /* options */ }]]

Plugin Options

Note: All config options are optional.

• webModulesUrl: The hosted URL path reference for web_modules imports. Can be:
  • An absolute path ("/web_modules"). This is the default.
  • An absolute URL ("https://foobar.com/web_modules/")
  • A relative path prefix ("./web_modules", "../web_modules"). NOTE: Relative paths are relative from the current working directory / Babel's "root".
• webModulesDir: The web_modules installed location on disk. Can be an absolute path, or relative to the current working directory.
  • Defaults to "${cwd}/web_modules".
• importMap: The name/location of the "import-map.json" file generated by Snowpack.
  • Defaults to "${webModulesDir}/import-map.json".
• moduleResolution: Control how the plugin rewrites relative/local imports. Defaults to "none".
  • "none": Leave relative imports untouched.
  • "node": Rewrite all relative paths to use node's built-in resolution, resolving things like missing file extensions and directory imports. This is useful to assist migrating an older, bundled project to Snowpack.
• ignore: Array of import specifiers to ignore and leave untouched / bare.
