您可以配置Next.js webpack加载器来加载markdown文件并将其作为字符串返回，例如：

• • 一月一日**

# Home

This is my **awesome** home!

• • 一米一米一**

import React from 'react';
import markdown from '../docs/home.md';

export default () => {
  return (
    <div>
      <pre>{markdown}</pre>
      <small><i>Import and render markdown using Next.js</i></small>
    </div>
  );
};

• • 一米二米一x**

{
  "name": "example",
  "version": "1.0.0",
  "scripts": {
    "dev": "next",
    "build": "next build",
    "start": "next start"
  },
  "dependencies": {
    "file-loader": "^1.1.6",
    "next": "^4.2.1",
    "raw-loader": "^0.5.1",
    "react": "^16.2.0",
    "react-dom": "^16.2.0"
  }
}

• • 一米三米一x**

module.exports = {
  webpack: (config) => {
    return Object.assign({}, config, {
      externals: Object.assign({}, config.externals, {
        fs: 'fs',
      }),
      module: Object.assign({}, config.module, {
        rules: config.module.rules.concat([
          {
            test: /\.md$/,
            loader: 'emit-file-loader',
            options: {
              name: 'dist/[path][name].[ext]',
            },
          },
          {
            test: /\.md$/,
            loader: 'raw-loader',
          }
        ]),
      }),
    });
  }
};

运行时：

$ npm run dev

会出现如下内容：

使用markdown字符串，你可以做任何你想做的事情。例如，用marksy处理它。

更快的"Next.js方法"是使用插件next-mdx
文件：https://github.com/vercel/next.js/tree/canary/packages/next-mdx

// next.config.js
const withMDX = require('@zeit/next-mdx')({
  extension: /\.mdx?$/
})
module.exports = withMDX({
  pageExtensions: ['js', 'jsx', 'mdx']
})

只需安装raw-loader

npm install --save raw-loader

然后编辑您的next.config.js

webpack: (config) => {
  config.module.rules.push({
    test: /\.md$/,
    use: 'raw-loader',
  });
  return config;
},

更新：不严格要求emit-file-loader，弃用raw-loader以支持资产模块

https://stackoverflow.com/a/47954368/895245的一些更新可能是由于最新的开发：

• 资产模块被取代raw-loader：https://stackoverflow.com/a/47954368/895245不再需要安装任何额外的软件包
• emit-file-loader似乎不再必要，不确定是否需要它，或者它是否用于更专业的东西

所以我们可以稍微简化一下
pages/index.js

import world from '../world.md'

export default function IndexPage() {
  return <div>hello {world}</div>
}

next.config.js

module.exports = {
  webpack: (config, { buildId, dev, isServer, defaultLoaders, webpack }) => {
    config.module.rules.push(
      {
        test: /\.md$/,
        // This is the asset module.
        type: 'asset/source',
      }
    )
    return config
  },
}

package.json

{
  "name": "test",
  "version": "1.0.0",
  "scripts": {
    "dev": "next",
    "build": "next build",
    "start": "next start"
  },
  "dependencies": {
    "next": "12.2.0",
    "react": "17.0.2",
    "react-dom": "17.0.2"
  }
}

让它从Typescript工作

遗憾的是，boch raw-loader和资产模块需要更多的打字工作：https://github.com/webpack-contrib/raw-loader/issues/56#issuecomment-423640398您必须创建一个文件：
global.d.ts

declare module '*.md'

否则，导入将失败，并显示：

Type error: Cannot find module '../world.md' or its corresponding type declarations.

完整示例：
global.d.ts

declare module '*.md'

页/索引.tsx

import world from '../world.md'

export default function IndexPage() {
  const what: string = 'my'
  // Would fail on build as desired.
  // const what2: int = 'world2'
  return <div>hello {what} {world}</div>
}

next.config.js

module.exports = {
  webpack: (config, { buildId, dev, isServer, defaultLoaders, webpack }) => {
    config.module.rules.push(
      {
        test: /\.md$/,
        type: 'asset/source',
      }
    )
    return config
  },
}
