Build Config#

builderConfig#

• Type: RsbuildConfig

Used to customize the configurations of Rsbuild. For detailed configurations, please refer to Rsbuild - Config.

• Example: Use resolve.alias to configure path aliases:

export default defineConfig({
  builderConfig: {
    resolve: {
      alias: {
        '@common': './src/common',
      },
    },
  },
});

• Example: Use tools.rspack to modify the Rspack configuration, such as registering a webpack or Rspack plugin:

export default defineConfig({
  builderConfig: {
    tools: {
      rspack: async config => {
        const { default: ESLintPlugin } = await import('eslint-webpack-plugin');
        config.plugins?.push(new ESLintPlugin());
        return config;
      },
    },
  },
});

builderPlugins#

• Type: RsbuildPlugin[]

Used to register Rsbuild plugins.

You can use the rich plugins of Rsbuild in the Rspress project to quickly extend the building capabilities.

• Example: Support Vue SFC through @rsbuild/plugin-vue

import { defineConfig } from 'rspress/config';
import { pluginVue } from '@rsbuild/plugin-vue';

export default defineConfig({
  builderPlugins: [pluginVue()],
});

• Example: Add Google analytics through rsbuild-plugin-google-analytics

import { defineConfig } from 'rspress/config';
import { pluginGoogleAnalytics } from 'rsbuild-plugin-google-analytics';

export default defineConfig({
  builderPlugins: [
    pluginGoogleAnalytics({
      // replace this with your Google tag ID
      id: 'G-xxxxxxxxxx',
    }),
  ],
});

• Example: Add Open Graph meta tags through rsbuild-plugin-open-graph

import { defineConfig } from 'rspress/config';
import { pluginOpenGraph } from 'rsbuild-plugin-open-graph';

export default defineConfig({
  builderPlugins: [
    pluginOpenGraph({
      title: 'My Website',
      type: 'website',
      // ...options
    }),
  ],
});

You can also override the built-in plugins @rsbuild/plugin-react, @rsbuild/plugin-sass and @rsbuild/plugin-less, and customize relevant plugin options.

• Example: Modify related options of built-in @rsbuild/plugin-less plugin

import { defineConfig } from 'rspress/config';
import { pluginLess } from '@rsbuild/plugin-less';

export default defineConfig({
  builderPlugins: [
    pluginLess({
      lessLoaderOptions: {
        lessOptions: {
          math: 'always',
        },
      },
    }),
  ],
});

Default Config#

If you need to view the default Rspack or Rsbuild configs, you can add the DEBUG=rsbuild parameter when running the rspress dev or rspress build command:

DEBUG=rsbuild rspress dev

After execution, the rsbuild.config.js file is created in the doc_build directory, which contains the complete builderConfig.

Please refer to Rsbuild - Debug Mode for more information on how to debug the Rsbuild.

markdown#

• Type: Object

Configure MDX-related compilation abilities.

markdown.remarkPlugins#

• Type: Array
• Default: []

Configure the remark plugins. for example:

import { defineConfig } from 'rspress/config';

export default defineConfig({
  markdown: {
    remarkPlugins: [
      [
        require('remark-autolink-headings'),
        {
          behavior: 'wrap',
        },
      ],
    ],
  },
});

markdown.rehypePlugins#

• Type: Array

Configure the rehype plugin. for example:

import { defineConfig } from 'rspress/config';

export default defineConfig({
  markdown: {
    rehypePlugins: [
      [
        require('rehype-autolink-headings'),
        {
          behavior: 'wrap',
        },
      ],
    ],
  },
});

markdown.checkDeadLinks#

• Type: boolean
• Default: false

Whether to check for dead links. for example:

import { defineConfig } from 'rspress/config';

export default defineConfig({
  markdown: {
    checkDeadLinks: true,
  },
});

After enabling this config, the framework will check the links in the document based on the conventional routing table. If there is an unreachable link, the build will throw an error and exit.

markdown.mdxRs#

• Type: boolean | { include: (filepath: string) => boolean }

• Default: true

Whether to use the Rust version of the MDX compiler. For example:

import { defineConfig } from 'rspress/config';

export default defineConfig({
  markdown: {
    // Switch to the JS version of the compiler
    mdxRs: false,
  },
});

You can also provide a function to determine which files use the Rust version of MDX compiler. For example:

import { defineConfig } from 'rspress/config';

export default defineConfig({
  markdown: {
    mdxRs: {
      include: (filepath: string) => filepath.includes('foo.mdx'),
    },
  },
});

markdown.showLineNumbers#

• Type: boolean

Whether to display the line number of the code block. Defaults to false.

markdown.defaultWrapCode#

• Type: boolean

Whether to enable long code line wrapping display by default. Defaults to false.

markdown.globalComponents#

• Type: string[]

Register component to the global scope, which will make it automatically available in every MDX file, without any import statements.For example:

import { defineConfig } from 'rspress/config';
import path from 'path';

export default defineConfig({
  markdown: {
    globalComponents: [path.join(__dirname, 'src/src/components/Alert.tsx')],
  },
});

Then you can use the Alert component in any MDX file:

<Alert type="info">This is a info alert</Alert>

markdown.highlightLanguages#

• Type: [string, string][]
• Default:

const DEFAULT_HIGHLIGHT_LANGUAGES = [
  ['js', 'javascript'],
  ['ts', 'typescript'],
  ['jsx', 'tsx'],
  ['xml', 'xml-doc'],
  ['md', 'markdown'],
  ['mdx', 'tsx'],
];

Rspress supports automatic import of highlighted languages and makes some language aliases by default.

• By default, it is implemented based on Prism.js. You can also switch to Shiki through @rspress/plugin-shiki.
• The default configuration alias languages include js, jsx, ts, tsx, xml, md, mdx.

You can also extend these default aliases, such as:

import { defineConfig } from 'rspress/config';
import path from 'path';

export default defineConfig({
  markdown: {
    highlightLanguages: [
      // Alias as md, full name as markdown
      ['md', 'markdown'],
    ],
  },
});

The alias of each language is configured in the format of [string, string]. The former is the alias of the language, and the latter is the full name of the language. You can go to File List to view the full names of all supported languages.
