rollup-plugin-root-import

Add the ability to import modules by the root path, like babel-root-slash-import.

// import a module relative to a specified root directory
import UserModel from '/models/user';

// illustrative - if we were in /views/user, we can reference a model's module
// using an absolute path from the root of the project, rather than relative to
// the current module
class UserView {
  // ...
}

Install

$ yarn add rollup-plugin-root-import

or

$ npm install --save-dev rollup-plugin-root-import

Usage

import { rollup } from 'rollup';
import rootImport from 'rollup-plugin-root-import';

rollup({
  entry: 'client/src/main.js',
  plugins: [
    rootImport({
      // Will first look in `client/src/*` and then `common/src/*`.
      root: `${__dirname}/common/src`,
      useInput: 'prepend',

      // If we don't find the file verbatim, try adding these extensions
      extensions: '.js',
    }),
  ],
});

API

rootImport([options])

Creates a rollup plugin to resolve absolute-pathed imports relative to the project's entry or specified root directory/ies.

Options:

• root an optional string or ordered array of strings, which represent the roots from which to try and resolve imports. You should specify absolute paths (i.e. using __dirname) in order for downstream Rollup plugins to match module IDs.
• useInput if provided, should be either 'prepend' or 'append', where each signify that the directory containing the entry should be prepended or appended to the array of roots, respectively. By default, if root is provided and useInput is not provided, the directory of the entry module will not be used to resolve absolute-pathed imports.
• extensions, if provided, specifies a string or ordered array of strings, each of which represents an extension to append to the resolved file if the import isn't found verbatim.
