/Angular 2

Browser support

Angular supports most recent browsers. This includes the following specific versions:

Chrome Firefox Edge IE Safari iOS Android IE mobile
latest latest 14 11 10 10 Marshmallow (6.0) 11
13 10 9 9 Lollipop(5.0, 5.1)
9 8 8 KitKat(4.4)
7 7 Jelly Bean(4.1, 4.2, 4.3)

Angular's continuous integration process runs unit tests of the framework on all of these browsers for every pull request, using SauceLabs and Browserstack.


Angular is built on the latest standards of the web platform. Targeting such a wide range of browsers is challenging because they do not support all features of modern browsers.

You can compensate by loading polyfill scripts ("polyfills") on the host web page (index.html) that implement missing features in JavaScript.

<script src="node_modules/core-js/client/shim.min.js"></script>

A particular browser may require at least one polyfill to run any Angular application. You may need additional polyfills for specific features.

The tables below can help you determine which polyfills to load, depending on the browsers you target and the features you use.

The suggested polyfills are the ones that run full Angular applications. You may need additional polyfills to support features not covered by this list. Note that polyfills cannot magically transform an old, slow browser into a modern, fast one.

Mandatory polyfills

These are the polyfills required to run an Angular application on each supported browser:

Browsers (desktop & mobile) Polyfills required
Chrome, Firefox, Edge, Safari 9+ None
Safari 7 & 8, IE10 & 11, Android 4.1+




Optional browser features to polyfill

Some features of Angular may require additional polyfills.

For example, the animations library relies on the standard web animation API, which is only available in Chrome and Firefox today. You'll need a polyfill to use animations in other browsers.

Here are the features which may require additional polyfills:

Feature Polyfill Browsers (desktop & mobile)

Web Animations

All but Chrome and FirefoxNot supported in IE9
Date, currency, decimal and percent pipes

Intl API

All but Chrome, Firefox, Edge, IE11 and Safari 10
NgClass on SVG elements


IE10, IE11
Http when sending and receiving binary data

Typed Array BlobFormData

IE 9

Suggested polyfills

Below are the polyfills which are used to test the framework itself. They are a good starting point for an application.
