|
| ## Upgrading from 12 to 13 |
|
|
| To update to Next.js version 13, run the following command using your preferred package manager: |
|
|
| ```bash filename="Terminal" |
| npm i next@13 react@latest react-dom@latest eslint-config-next@13 |
| ``` |
|
|
| ```bash filename="Terminal" |
| yarn add next@13 react@latest react-dom@latest eslint-config-next@13 |
| ``` |
|
|
| ```bash filename="Terminal" |
| pnpm i next@13 react@latest react-dom@latest eslint-config-next@13 |
| ``` |
|
|
| ```bash filename="Terminal" |
| bun add next@13 react@latest react-dom@latest eslint-config-next@13 |
| ``` |
|
|
| > **Good to know:** If you are using TypeScript, ensure you also upgrade `@types/react` and `@types/react-dom` to their latest versions. |
|
|
| ### v13 Summary |
|
|
| - The [Supported Browsers](/docs/architecture/supported-browsers) have been changed to drop Internet Explorer and target modern browsers. |
| - The minimum Node.js version has been bumped from 12.22.0 to 16.14.0, since 12.x and 14.x have reached end-of-life. |
| - The minimum React version has been bumped from 17.0.2 to 18.2.0. |
| - The `swcMinify` configuration property was changed from `false` to `true`. See [Next.js Compiler](/docs/architecture/nextjs-compiler) for more info. |
| - The `next/image` import was renamed to `next/legacy/image`. The `next/future/image` import was renamed to `next/image`. A [codemod is available](/docs/pages/guides/upgrading/codemods#next-image-to-legacy-image) to safely and automatically rename your imports. |
| - The `next/link` child can no longer be `<a>`. Add the `legacyBehavior` prop to use the legacy behavior or remove the `<a>` to upgrade. A [codemod is available](/docs/pages/guides/upgrading/codemods#new-link) to automatically upgrade your code. |
| - The `target` configuration property has been removed and superseded by [Output File Tracing](/docs/pages/api-reference/config/next-config-js/output). |
|
|
| ## Migrating shared features |
|
|
| Next.js 13 introduces a new [`app` directory](/docs/app) with new features and conventions. However, upgrading to Next.js 13 does **not** require using the new `app` Router. |
|
|
| You can continue using `pages` with new features that work in both directories, such as the updated [Image component](#image-component), [Link component](#link-component), [Script component](#script-component), and [Font optimization](#font-optimization). |
|
|
| ### `<Image/>` Component |
|
|
| Next.js 12 introduced many improvements to the Image Component with a temporary import: `next/future/image`. These improvements included less client-side JavaScript, easier ways to extend and style images, better accessibility, and native browser lazy loading. |
|
|
| Starting in Next.js 13, this new behavior is now the default for `next/image`. |
|
|
| There are two codemods to help you migrate to the new Image Component: |
|
|
| - [next-image-to-legacy-image](/docs/pages/guides/upgrading/codemods#next-image-to-legacy-image): This codemod will safely and automatically rename `next/image` imports to `next/legacy/image` to maintain the same behavior as Next.js 12. We recommend running this codemod to quickly update to Next.js 13 automatically. |
| - [next-image-experimental](/docs/pages/guides/upgrading/codemods#next-image-experimental): After running the previous codemod, you can optionally run this experimental codemod to upgrade `next/legacy/image` to the new `next/image`, which will remove unused props and add inline styles. Please note this codemod is experimental and only covers static usage (such as `<Image src={img} layout="responsive" />`) but not dynamic usage (such as `<Image {...props} />`). |
|
|
| Alternatively, you can manually update by following the [migration guide](/docs/pages/guides/upgrading/codemods#next-image-experimental) and also see the [legacy comparison](/docs/pages/api-reference/components/image-legacy#comparison). |
|
|
| ### `<Link>` Component |
|
|
| The [`<Link>` Component](/docs/pages/api-reference/components/link) no longer requires manually adding an `<a>` tag as a child. This behavior was added as an experimental option in [version 12.2](https://nextjs.org/blog/next-12-2) and is now the default. In Next.js 13, `<Link>` always renders `<a>` and allows you to forward props to the underlying tag. |
|
|
| For example: |
|
|
| ```jsx |
| import Link from 'next/link' |
|
|
| |
| <Link href="/about"> |
| <a>About</a> |
| </Link> |
|
|
| |
| <Link href="/about"> |
| About |
| </Link> |
| ``` |
|
|
| To upgrade your links to Next.js 13, you can use the [`new-link` codemod](/docs/pages/guides/upgrading/codemods#new-link). |
|
|
| ### `<Script>` Component |
|
|
| The behavior of [`next/script`](/docs/pages/api-reference/components/script) has been updated to support both `pages` and `app`. If incrementally adopting `app`, read the [upgrade guide](/docs/pages/guides/upgrading). |
|
|
| ### Font Optimization |
|
|
| Previously, Next.js helped you optimize fonts by inlining font CSS. Version 13 introduces the new [`next/font`](/docs/pages/api-reference/components/font) module which gives you the ability to customize your font loading experience while still ensuring great performance and privacy. |
|
|
| See [Optimizing Fonts](/docs/pages/api-reference/components/font) to learn how to use `next/font`. |
