TypeScript 支持

Docusaurus 由 TypeScript 写成，并提供一流的 TypeScript 支持。

The minimum required version is TypeScript 5.0.

Initialization​

Docusaurus 支持编写和使用 TypeScript 主题组件。 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

下面是一些关于如何将现有项目迁移到 TypeScript 的指南。

Setup​

Add the following packages to your project:

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

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

tsconfig.json
{
  "extends": "@docusaurus/tsconfig",
  "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.

现在，你可以开始撰写 TypeScript 主题组件了。

Typing the config file​

It is possible to use a TypeScript config file in Docusaurus.

docusaurus.config.ts
import type {Config} from '@docusaurus/types';
import type * as Preset from '@docusaurus/preset-classic';

const config: Config = {
  title: 'My Site',
  favicon: 'img/favicon.ico',

  /* Your site config here */

  presets: [
    [
      'classic',
      {
        /* Your preset config here */
      } satisfies Preset.Options,
    ],
  ],

  themeConfig: {
    /* Your theme config here */
  } satisfies Preset.ThemeConfig,
};

export default config;
It is also possible to use JSDoc type annotations within a .js file:

默认情况下，Docusaurus TypeScript 配置不会对 JavaScript 文件进行类型检查。

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

docusaurus.config.js
// @ts-check

/** @type {import('@docusaurus/types').Config} */
const config = {
  tagline: 'Dinosaurs are cool',
  favicon: 'img/favicon.ico',

  /* Your site config here */

  presets: [
    [
      '@docusaurus/preset-classic',
      /** @type {import('@docusaurus/preset-classic').Options} */
      (
        {
          /* Your preset config here */
        }
      ),
    ],
  ],
  themeConfig:
    /** @type {import('@docusaurus/preset-classic').ThemeConfig} */
    (
      {
        /* Your theme config here */
      }
    ),
};

export default config;
提示

类型注解非常有用，它能够帮助你的编辑器理解配置对象的类型！

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

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.
