Docusaurus for typescript source code documentation

Docusaurus is a static site generator that can be used to create documentation for your project. You can use it to document your TypeScript code by following these steps.

Installation

Install Docusaurus using npm:

npm install --save-dev docusaurus

Create a new Docusaurus project and follow the prompts to set up your documentation site:

npx docusaurus-init

Create a TypeScript configuration file (tsconfig.json) in the root directory of your project. This file specifies the compiler options for your TypeScript code.

In the docusaurus.config.js file, add the TypeScript configuration file to the presets array under the docs field. This will tell Docusaurus to use the TypeScript configuration when processing your documentation files:

module.exports = {
  ...
  docs: {
    ...
    presets: [
      [
        '@docusaurus/preset-classic',
        {
          ...
          tsconfig: './tsconfig.json',
        },
      ],
    ],
  },
  ...
};

Create your documentation files in the docs directory, using the .tsx extension for TypeScript files that contain JSX. You can then reference these files in your documentation using the standard Docusaurus markdown syntax.

Run the Docusaurus build command to generate your documentation site:

npx docusaurus build

This will compile your TypeScript code and generate the static documentation site in the build directory.

TypeDoc Integration

To use the docusaurus-plugin-typedoc plugin with Docusaurus, follow these steps:

Install the plugin using npm:

npm install --save-dev docusaurus-plugin-typedoc

In your Docusaurus configuration file (docusaurus.config.js), add the plugin to the plugins array:

module.exports = {
  ...
  plugins: ['docusaurus-plugin-typedoc'],
  ...
};

Create a TypeScript configuration file (tsconfig.json) in the root directory of your project. This file specifies the compiler options for your TypeScript code.

In the docusaurus.config.js file, add the TypeScript configuration file to the typedoc field under the plugins section:

module.exports = {
  ...
  plugins: [
    [
      'docusaurus-plugin-typedoc',
      // Plugin / TypeDoc options
      {
        entryPoints: ['../src/index.ts'],
        tsconfig: './tsconfig.json',
      },
    ],
  ],
  ...
};

Run the Docusaurus build command to generate your documentation site:

npx docusaurus build

This will process your TypeScript code using TypeDoc and generate documentation for it, which will be included in your documentation site.

Conclusion

Docusaurus combined with TypeDoc provides an automated documentation pipeline for TypeScript projects, generating navigable API documentation directly from source code comments.
