Include Files

About 3 min

Let the Markdown file in your VuePress site support including other files.

Settings

import { defineUserConfig } from "vuepress";
import { hopeTheme } from "vuepress-theme-hope";

export default defineUserConfig({
  theme: hopeTheme({
    markdown: {
      include: true,
    },
  }),
});

Syntax

Use  to include a file.

To partially import the file, you can specify the range of lines to be included:

Also, you can include file region:

File region

File region is a concept in vscode, where the region content is surrounded by #region and #endregion comments.

Here are some examples:

HTML

<!doctype html>
<html lang="zh-CN">
  <head>
    <meta charset="UTF-8" />
    <meta http-equiv="X-UA-Compatible" content="IE=edge" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <title>Document</title>
  </head>
  <body>
    <!-- region snippet -->

      Lorem ipsum dolor, sit amet consectetur adipisicing elit. Eligendi,
      repellendus. Voluptatibus alias cupiditate at, fuga tenetur error officiis
      provident quisquam autem, porro facere! Neque quibusdam animi quaerat
      eligendi recusandae eaque.
    </p>
    <!-- endregion snippet -->

You can also set an object to customize include filepath and include behavior.

interface IncludeOptions {
  /**
   * handle include filePath
   *
   * @default (path) => path
   */
  resolvePath?: (path: string, cwd: string | null) => string;
  /**
   * Whether deep include files in included Markdown files
   *
   * @default false
   */
  deep?: boolean;
  /**
   * Whether use `<!-- @include: xxx -->` instead of `@include: xxx` to include files
   *
   * @default true
   */
  useComment?: boolean;
  /**
   * Whether resolve the image related path in the included Markdown file
   *
   * @default true
   */
  resolveImagePath?: boolean;
  /**
   * Whether resolve the related file link path in the included Markdown file
   *
   * @default true
   */
  resolveLinkPath?: boolean;
}

E.g.: you can use @src as an alias for your source directory.

import { defineUserConfig } from "vuepress";
import { getDirname, path } from "vuepress/utils";
import { hopeTheme } from "vuepress-theme-hope";

const __dirname = getDirname(import.meta.url);

export default defineUserConfig({
  theme: hopeTheme({
    markdown: {
      // Add `@src` alias support
      include: {
        resolvePath: (file) => {
          if (file.startsWith("@src"))
            return file.replace("@src", path.resolve(__dirname, ".."));

          return file;
        },
      },
    },
  }),
});

Also, to place your Markdown files directly besides your actual files, but don't want them rendered as pages, you can set pagePatterns options in VuePress config. See pagePatterns for more details.

import { defineUserConfig } from "vuepress";
import { hopeTheme } from "vuepress-theme-hope";

export default defineUserConfig({
  // now any file with `.snippet.md` extension will not be rendered as a page
  pagePatterns: ["**/*.md", "!**/*.snippet.md", "!.vuepress", "!node_modules"],

  theme: hopeTheme({
    markdown: {
      include: true,
    },
  }),
});
