Export-all.macro NPM

The problem

You want to export all files that match a glob without having to export them individually.

This solution

This is a babel-plugin-macro which allows you to export files that match a glob. It supports export statements for synchronous resolution.

Installation

This module is distributed via npm which is bundled with node and should be installed as one of your project's devDependencies:

npm install --save-dev export-all.macro

Usage

Once you've configured babel-plugin-macros you can import/require export-all.macro.

The exportAll functions accept a glob and will transpile your code to export statements for each file that matches the given glob.

Let's imagine you have a directory called my-files with the files a.js, b.js, c.js, and d.js.

Here are a few before/after examples:

exportAll uses static exports: README:1 exportAll uses static exports

import exportAll from 'export-all.macro'

exportAll('./files/*.js')

      ↓ ↓ ↓ ↓ ↓ ↓

export * from './files/a.js'
export * from './files/b.js'
export * from './files/c.js'
export * from './files/d.js'

Caveats

Some static analysis tools (like ESLint, Flow, and Jest) wont like this very much without a little additional work. So Jest's watch mode may not pick up all your tests that are relevant based on changes and some ESLint plugins (like eslint-plugin-import) will probably fail on this.
