useAmp

AMP support is one of our advanced features, you can read more about AMP here.

To enable AMP, add the following config to your page:

export const config = { amp: true }

The amp config accepts the following values:

• true - The page will be AMP-only
• 'hybrid' - The page will have two versions, one with AMP and another one with HTML

To learn more about the amp config, read the sections below.

AMP First Page

Take a look at the following example:

export const config = { amp: true }   function About(props) {   return <h3>My AMP About Page!</h3> }   export default About

The page above is an AMP-only page, which means:

• The page has no Next.js or React client-side runtime
• The page is automatically optimized with AMP Optimizer, an optimizer that applies the same transformations as AMP caches (improves performance by up to 42%)
• The page has a user-accessible (optimized) version of the page and a search-engine indexable (unoptimized) version of the page

Hybrid AMP Page

Take a look at the following example:

import { useAmp } from 'next/amp'   export const config = { amp: 'hybrid' }   function About(props) {   const isAmp = useAmp()     return (     <div>       <h3>My AMP About Page!</h3>       {isAmp ? (         <amp-img           width="300"           height="300"           src="/my-img.jpg"           alt="a cool image"           layout="responsive"         />       ) : (         <img width="300" height="300" src="/my-img.jpg" alt="a cool image" />       )}     </div>   ) }   export default About

The page above is a hybrid AMP page, which means:

• The page is rendered as traditional HTML (default) and AMP HTML (by adding ?amp=1 to the URL)
• The AMP version of the page only has valid optimizations applied with AMP Optimizer so that it is indexable by search-engines

The page uses useAmp to differentiate between modes, it's a React Hook that returns true if the page is using AMP, and false otherwise.
