babel-preset-es2015-ie

library6.7.0jsnpmunverified

A Babel preset that includes all ES2015 plugins with additional transforms to ensure compatibility with Internet Explorer 9 and 10. Version 6.7.0 is the latest stable release, designed for Babel 6. It wraps the official babel-preset-es2015 and adds IE-specific polyfills or transforms for features like default parameters, destructuring, and spread operators that are not fully supported in older IE versions. Unlike the base preset, it targets IE>=9 specifically, making it suitable for legacy enterprise applications. The package is no longer actively maintained as Babel 6 is deprecated in favor of Babel 7 and @babel/preset-env.

Default (as preset)

✓ { "presets": ["es2015-ie"] }

✗ { "presets": ["babel-preset-es2015-ie"] }

In .babelrc or Babel config, use the preset name without the 'babel-preset-' prefix.

Default (Node API)

✓ require('babel-core').transform('code', { presets: ['es2015-ie'] })

✗ var preset = require('babel-preset-es2015-ie'); require('babel-core').transform('code', { presets: [preset] })

When using the Node API, pass the preset name as a string, not the required module.

Via CLI

✓ babel script.js --presets es2015-ie

✗ babel script.js --presets babel-preset-es2015-ie

CLI also expects the short preset name.

Shows installation, configuration in .babelrc, and a basic ES2015 arrow function/map example that will be transpiled for IE9+.

// Install the preset // npm install --save-dev babel-preset-es2015-ie // .babelrc { "presets": ["es2015-ie"] } // Example ES2015 code (will be transpiled for IE9+) const sum = (a, b) => a + b; let numbers = [1, 2, 3]; let doubled = numbers.map(n => n * 2); console.log(doubled);

Debug

Known issues

deprecatedbabel-preset-es2015-ie is deprecated; Babel 6 is end-of-life. Use @babel/preset-env with IE targets instead.

fix

Migrate to Babel 7 and use @babel/preset-env with targets: { ie: '9' }.

affects: >=0.0.0

gotchaThe preset does not include a polyfill for Promise, Map, Set, etc. Those must be added separately (e.g., babel-polyfill).

fix

Add import 'babel-polyfill' or configure core-js polyfills in Babel 7.

affects: >=6.0.0

breakingThis preset is designed for Babel 6 only. It will not work with Babel 7 (which uses @babel/ scoped packages).

fix

Upgrade to @babel/preset-env and use Babel 7.

affects: >=0.0.0

Errors

fix

Downgrade to Babel 6 or migrate to @babel/preset-env.

Add additional presets or plugins (e.g., babel-plugin-syntax-dynamic-import).
