Suporte a TypeScript

Docusaurus is written in TypeScript and provides first-class TypeScript support.

Initialization​

O Docusaurus suporta escrever e usar componentes de temas TypeScript. If the init template provides a TypeScript variant, you can directly initialize a site with full TypeScript support by using the --typescript flag.

npx create-docusaurus@latest my-website classic --typescript

Below are some guides on how to migrate an existing project to TypeScript.

Setup​

To start using TypeScript, add @docusaurus/module-type-aliases and the base TS config to your project:

npm install --save-dev typescript @docusaurus/module-type-aliases @tsconfig/docusaurus

Then add tsconfig.json to your project root with the following content:

tsconfig.json
{
  "extends": "@tsconfig/docusaurus/tsconfig.json",
  "compilerOptions": {
    "baseUrl": "."
  }
}

Docusaurus doesn't use this tsconfig.json to compile your project. It is added just for a nicer Editor experience, although you can choose to run tsc to type check your code for yourself or on CI.

Agora você pode começar a escrever componentes de tema TypeScript.

Typing the config file​

It is not possible to use a TypeScript config file in Docusaurus unless you compile it yourself to JavaScript.

We recommend using JSDoc type annotations:

docusaurus.config.js
// @ts-check

/** @type {import('@docusaurus/types').Plugin} */
function MyPlugin(context, options) {
  return {
    name: 'my-plugin',
  };
}

/** @type {import('@docusaurus/types').Config} */
const config = {
  title: 'Docusaurus',
  tagline: 'Build optimized websites quickly, focus on your content',
  organizationName: 'facebook',
  projectName: 'docusaurus',
  plugins: [MyPlugin],
  presets: [
    [
      '@docusaurus/preset-classic',
      /** @type {import('@docusaurus/preset-classic').Options} */
      ({
        docs: {
          path: 'docs',
          sidebarPath: 'sidebars.js',
        },
        blog: {
          path: 'blog',
          postsPerPage: 5,
        },
      }),
    ],
  ],
  themeConfig:
    /** @type {import('@docusaurus/preset-classic').ThemeConfig} */
    ({
      colorMode: {
        defaultMode: 'dark',
      },
      navbar: {
        hideOnScroll: true,
        title: 'Docusaurus',
        logo: {
          alt: 'Docusaurus Logo',
          src: 'img/docusaurus.svg',
          srcDark: 'img/docusaurus_keytar.svg',
        },
      },
    }),
};

module.exports = config;
tip

Type annotations are very useful and help your IDE understand the type of config objects!

The best IDEs (VS Code, WebStorm, IntelliJ...) will provide a nice auto-completion experience.

info

By default, the Docusaurus TypeScript config does not type-check JavaScript files.

The // @ts-check comment ensures the config file is properly type-checked when running npx tsc.

Swizzling TypeScript theme components​

For themes that support TypeScript theme components, you can add the --typescript flag to the end of the swizzle command to get TypeScript source code. For example, the following command will generate index.tsx and styles.module.css into src/theme/Footer.

npm run swizzle @docusaurus/theme-classic Footer -- --typescript

All official Docusaurus themes support TypeScript theme components, including theme-classic, theme-live-codeblock, and theme-search-algolia. If you are a Docusaurus theme package author who wants to add TypeScript support, see the Lifecycle APIs docs.
