ember-classic-import-meta-glob

Implements RFC#939: import.meta.glob for ember-classic (pre-embroider).

Compatibility

See working demos here: https://github.com/NullVoxPopuli/ember-import-meta-glob-demos

• Apps using ember-source v3.28
• ember-auto-import v2
  • unless the paths being imported are under the allowAppImports config
• not embroider. For embroider, use babel-plugin-transform-vite-meta-glob

Installation

pnpm add ember-classic-import-meta-glob

Usage

Default usage:

// If you type this in your app:
const widgets = import.meta.glob('./widgets/*.js')

// It gets automatically converted into something like this:
const widgets = {
  './widgets/first.js': () => import('./widgets/first.js'),
  './widgets/second.js': () => import('./widgets/second.js'),
}

Example with eager: true

// If you type this in your app:
const widgets = import.meta.glob('./widgets/*.js', { eager: true } )

// It gets automatically converted into something like this:
import * as a from './widgets/first.js';
import * as b from './widgets/first.js';
const widgets = {
  './widgets/first.js': a,
  './widgets/second.js': b,
}

Differences from RFC#939

• Extensions in the import paths are optional -- this because they do not exist at runtime, and the implementation for this version of import.meta.glob cannot determine what the original file names were.
• the keys in the return object from glob will not contain file name extensions, because they do not exist at runtime.

For ember-classic, this is meant to ease migration to the new, modern features, reducing the overall diff you'd need if you didn't have entire feature sets that are available to embroider.
