ember-cli-babel-polyfills

library2.0.1jsnpmunverified

An Ember addon (v2.0.1, latest) that automatically produces split builds of Babel polyfills (using core-js directly since v2.0.0) for evergreen and legacy browsers. It injects three script tags into index.html: polyfill-shared.js, polyfill-evergreen.js, and polyfill-legacy.js (the latter with nomodule attribute to skip modern browsers). Key differentiator: dynamic polyfill generation via Babel's presetEnv, so only necessary polyfills are shipped to each browser category. Suitable for Ember apps using Babel 7+; drops support for Babel 6 in v2.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

default (addon)

✓ ember install ember-cli-babel-polyfills

✗ npm install ember-cli-babel-polyfills --save-dev

Install as an Ember addon via ember install; direct npm install may miss blueprint steps.

EmberCliBabelPolyfillsConfig

✓ import type { EmberCliBabelPolyfillsConfig } from 'ember-cli-babel-polyfills';

Type is exported for TypeScript config usage, but not a runtime value.

Configuration in ember-cli-build.js

✓ let app = new EmberApp(defaults, { 'ember-cli-babel-polyfills': { evergreenTargets: [...] } });

✗ let app = new EmberApp(defaults, { babelPolyfills: { ... } });

Key must be the addon name as string; common mistake is using a different key.

Installs the addon and shows basic configuration for customizing browser targets.

// Install the addon ember install ember-cli-babel-polyfills // No further configuration needed; polyfills are auto-added. // To customize targets, edit ember-cli-build.js: let app = new EmberApp(defaults, { 'ember-cli-babel-polyfills': { evergreenTargets: [ 'last 2 Chrome versions', 'last 2 Firefox versions', 'last 2 Safari versions', ], legacyTargets: [ 'last 1 version', '> 1%', 'not dead', ], includeScriptTags: true, }, });

Debug

Known issues

breakingv2.0.0 drops support for Babel 6 and switches from @babel/polyfill to core-js directly.

fix

Upgrade to Babel 7 and ensure your app uses ember-cli-babel ^7.0.0.

affects: >=2.0.0

gotchaThe addon expects ember-cli-build.js configuration key to be exactly 'ember-cli-babel-polyfills' (string).

fix

Use string key 'ember-cli-babel-polyfills' in EmberApp options.

affects: *

gotchaincludeScriptTags: false will not inject any script tags; you must manually add them.

fix

Set includeScriptTags: true or manually add polyfill scripts to your index.html.
