With Polyfills

Next.js supports IE11 and all modern browsers (Edge, Firefox, Chrome, Safari, Opera, et al) with no required configuration. It also adds some polyfills by default.

If your own code or any external npm dependencies require features not supported by your target browsers, you need to add polyfills yourself.

In this case, you should add a top-level import for the specific polyfill you need in your Custom <App> or the individual component.

Deploy your own

Deploy the example using Vercel:

How to use

Execute create-next-app with npm or Yarn to bootstrap the example:

npx create-next-app --example with-polyfills with-polyfills-app
# or
yarn create next-app --example with-polyfills with-polyfills-app

Deploy it to the cloud with Vercel (Documentation).
