• AMP

AMP支持是我们的高级功能之一，您可以在这里阅读更多关于AMP的信息.

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

export const config = { amp: true }

The ampconfig 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 ampconfig, 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=1to 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 useAmpto differentiate between modes, it's a React Hook that returns trueif the page is using AMP, and falseotherwise.
