rollup-plugin-node-resolve-next v0.3.0

rollup-plugin-node-resolve-next

Rollup plugin for imports resolution using enhanced Node.js algorithm.

Could be used as an alternative to both rollup-plugin-node-resolve and rollup-plugin-node-resolve-angular modules.

Features

• Resolves imported modules using Node.js Resolution Algorithm

• Doesn't implement the resolution on it's own, but instead delegates this complex task to a well supported module: browserify/resolve

• Has a well-structured architecture and doesn't mix the concepts like rollup-plugin-node-resolve does. Module resolution and embedding conditionals are two separate concepts

• Allows flexibility in control of which modules will be embedded and which externalized using glob patterns on module ids (more flexible and convenient solution)

• Supports main/module/es2015 fields of package.json for different build targets

• Reliable: written in TypeScript and automatically tested

• Deduplicates dependencies by resolving symlinks in paths (useful in monorepo projects)

Example

// rollup.config.js
import nodeResolveNext from 'rollup-plugin-node-resolve-next';

export default {
  input: 'main.js',
  output: {
    file: 'bundle.js',
    format: 'es',
  },
  plugins: [
    nodeResolveNext({
      mode: 'ESM2015',
      embed: {
        mode: 'EMBED_MATCHED',
        patterns: [
          '@lodash/*',
          'tslib',
        ] ,
      },
      extensions: ['.js', '.jsx'],
    }),
  ],
};

Options

options.mode [enum/string] — controls the build target. See the Build Targets section for more details

options.embed.mode [enum/string] — controls the module embedding mode, possible values are:

• EMBED_EVERYTHING — embeds all imported modules to the bundle
• EMBED_MATCHED — embeds only matched modules
• EMBED_UNMATCHED — embeds only non-matched modules

options.embed.patterns [Array<string>] — list of glob patterns used to configure the matching. Used only in EMBED_MATCHED and EMBED_UNMATCHED modes.

options.extensions [Array<string>] — list of allowed extensions (['.js'] by default).

options.resolveSymlinks [boolean] — Whether to resolve symlinks in the destination paths. This will help to deduplicate dependencies in monorepo projects or in projects where npm link is used.

Build Targets

The plugin supports various main fields from package.json manifests of the imported modules for different build targets:

• In NORMAL mode only the main field is used (this is the default)
• In ESM5 mode the module field is used with fallback to main

• In ESM2015 mode the es2015 field is used with fallback to module or main
