Docusaurus OpenAPI Doc Generator

OpenAPI plugin for generating API reference docs in Docusaurus v2.

---

Overview

The docusaurus-plugin-openapi-docs package extends the Docusaurus CLI with commands for generating MDX using the OpenAPI specification as the source. The resulting MDX is fully compatible with plugin-content-docs and can be used to render beautiful reference API docs by setting docItemComponent to @theme/ApiItem, a custom component included in the docusaurus-theme-openapi-docs theme.

Key Features:

• Compatible: Works with Swagger 2.0 and OpenAPI 3.0.
• Fast: Convert large OpenAPI specs into MDX docs in seconds. 🔥
• Stylish: Based on the same Infima styling framework that powers the Docusaurus UI.
• Flexible: Supports single, multi and even micro OpenAPI specs.

Configuring docusaurus.config.js (Plugin and theme usage)

Here is an example of properly configuring docusaurus.config.js file for docusaurus-plugin-openapi-docs and docusaurus-theme-openapi-docs usage.

// docusaurus.config.js

{
  presets: [
    [
      "classic",
      /** @type {import('@docusaurus/preset-classic').Options} */
      ({
        docs: {
          sidebarPath: require.resolve("./sidebars.js"),
          editUrl:
            "https://github.com/facebook/docusaurus/tree/main/packages/create-docusaurus/templates/shared/",
          docLayoutComponent: "@theme/DocPage",
          docItemComponent: "@theme/ApiItem" // derived from docusaurus-theme-openapi-docs
        },
        blog: {
          showReadingTime: true,
          editUrl:
            "https://github.com/facebook/docusaurus/tree/main/packages/create-docusaurus/templates/shared/"
        },
        theme: {
          customCss: require.resolve("./src/css/custom.css")
        }
      })
    ]
  ],

  plugins: [
    [
      'docusaurus-plugin-openapi-docs',
      {
        id: "api", // plugin id
        docsPluginId: "classic", // id of plugin-content-docs or preset for rendering docs
        config: {
          petstore: { // the <id> referenced when running CLI commands
            specPath: "examples/petstore.yaml", // path to OpenAPI spec, URLs supported
            outputDir: "api/petstore", // output directory for generated files
            sidebarOptions: { // optional, instructs plugin to generate sidebar.js
              groupPathsBy: "tag", // group sidebar items by operation "tag"
            },
          },
          burgers: {
            specPath: "examples/food/burgers/openapi.yaml",
            outputDir: "api/food/burgers",
          }
        }
      },
    ]
  ],
  themes: ["docusaurus-theme-openapi-docs"], // export theme components
}

Note: You may optionally configure a dedicated @docusaurus/plugin-content-docs instance for use with docusaurus-theme-openapi-docs by setting docItemComponent to @theme/ApiItem.

Generating OpenAPI Docs

To generate all OpenAPI docs, run the following command from the root directory of your project:

yarn docusaurus gen-api-docs all

This will generate API docs for all of the OpenAPI specification (OAS) files referenced in your docusaurus-plugin-openapi-docs config.

You may also generate OpenAPI docs for a single path or OAS by specifying the unique id:

yarn docusaurus gen-api-docs <id>

Example:

yarn docusaurus gen-api-docs burgers

The example above will only generate API docs relative to burgers.

Cleaning API Docs

To clean/remove all API Docs, run the following command from the root directory of your project:

yarn docusaurus clean-api-docs all

You may also remove a particular set of API docs by specifying the unique id of your desired spec instance.

yarn docusaurus clean-api-docs <id>

Example:

yarn docusaurus clean-api-docs burgers

The example above will remove all API docs relative to burgers.

Versioning OpenAPI docs

To generate all versioned OpenAPI docs, run the following command from the root directory of your project:

yarn docusaurus gen-api-docs:version <id>:all

Example:

yarn docusaurus gen-api-docs:version petstore:all

This will generate API docs for all of the OpenAPI specification (OAS) files referenced in your versions config and will also generate a versions.json file.

Substitue all with a specific version ID to generate/clean a specific version. Generating for all or a specific version ID will automatically update the versions.json file.
