Overview

OpenAPI plugin for generating API reference docs in Docusaurus v3.

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 when combined with the docusaurus-theme-openapi-docs theme.

Key Features:

Compatible: Works with Swagger 2.0 and OpenAPI 3.x.
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.

Compatibility Matrix

Docusaurus OpenAPI Docs	Docusaurus
4.0.x (current)	`3.5.0 - 3.5.2`
3.0.x (end-of-support)	`3.0.1 - 3.4.0`
2.2.3 (legacy)	`2.4.1 - 2.4.3`
1.7.3 (end-of-support)	`2.0.1 - 2.2.0`

tip

If you"re building a Docusaurus site from scratch the easiest way to get started is by installing from template.

Bootstrapping from Template (new Docusaurus site)

Run the following to bootstrap a Docsaurus v2 site (classic theme) with docusaurus-openapi-docs:

npx create-docusaurus@3.5.2 my-website --package-manager yarn

When prompted to select a template choose Git repository.

Template Repository URL:

https://github.com/PaloAltoNetworks/docusaurus-template-openapi-docs.git

When asked how the template repo should be cloned choose "copy" (unless you know better).

cd my-website
yarn start

If all goes well, you should be greeted by a brand new Docusaurus site that includes API reference docs for the ubiquitous Petstore API!

Installation (existing Docusaurus site)

note

Both the plugin and theme are currently designed to pair with a specific Docusaurus release. The Docusaurus badge in the README.md and at the top of this page will always reflect the current compatible versions.

Plugin

yarn add docusaurus-plugin-openapi-docs

Theme

yarn add docusaurus-theme-openapi-docs

Configuration

Configuring `docusaurus.config.ts` (Plugin and theme usage)

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

note

Instructions may differ slightly for sites that haven't migrated to typescript.

// docusaurus.config.ts
// note that parts of the complete config were left out for brevity
import type * as Preset from "@docusaurus/preset-classic";
import type { Config } from "@docusaurus/types";
import type * as Plugin from "@docusaurus/types/src/plugin";
import type * as OpenApiPlugin from "docusaurus-plugin-openapi-docs";

{
  presets: [
    [
      "classic",
      {
        docs: {
          sidebarPath: "./sidebars.ts",
          docItemComponent: "@theme/ApiItem", // Derived from docusaurus-theme-openapi
        },
        theme: {
          customCss: "./src/css/custom.css",
        },
      } satisfies Preset.Options,
    ],
  ],

  plugins: [
    [
      'docusaurus-plugin-openapi-docs',
      {
        id: "api", // plugin id
        docsPluginId: "classic", // configured for preset-classic
        config: {
          petstore: {
            specPath: "examples/petstore.yaml",
            outputDir: "docs/petstore",
            sidebarOptions: {
              groupPathsBy: "tag",
            },
          } satisfies OpenApiPlugin.Options,
        }
      },
    ]
  ],
  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:

note

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

yarn docusaurus gen-api-docs all

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

yarn docusaurus gen-api-docs <id>

Example:

generating API docs for 'petstore'

yarn docusaurus gen-api-docs petstore

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:

cleaning API docs for 'petstore'

yarn docusaurus clean-api-docs petstore

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

Examples:

generate all versioned API docs for 'petstore'

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

generate version 1.0.0 API docs for 'petstore'

yarn docusaurus gen-api-docs:version petstore:1.0.0

tip

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.

See versions options for a list of available options. For a complete example of how to configure versining see the demo configuration.
