Angular supports most recent browsers. This includes the following specific versions:
|Firefox||latest and extended support release (ESR)|
|Edge||2 most recent major versions|
|Safari||2 most recent major versions|
|iOS||2 most recent major versions|
|Android||2 most recent major versions|
Angular's continuous integration process runs unit tests of the framework on all of these browsers for every pull request, using Sauce Labs.
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 compensate by loading polyfill scripts ("polyfills") for the browsers that you must support. See instructions on how to include polyfills into your project below.
The suggested polyfills are the ones that run full Angular applications. You might need additional polyfills to support features not covered by this list.
NOTE: Polyfills cannot magically transform an old, slow browser into a modern, fast one.
The Angular CLI provides support for polyfills. If you are not using the CLI to create your projects, see Polyfill instructions for non-CLI users.
When you create a project with the
ng new command, a
zone.js) are installed automatically for you when you create your project with
ng new, and their corresponding
importstatements are already enabled in the
If you are not using the CLI, add your polyfill scripts directly to the host web page (
