Overview

OpenAPI plugin for generating API reference docs in Docusaurus v2.

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, interactive API reference docs.

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.

Compatibility Matrix

Docusaurus OpenAPI Docs	Docusaurus
3.0.0-beta.x (beta)	`3.0.1 - 3.1.1`
2.0.x (current)	`2.4.1 - 2.4.3`
1.7.3 (legacy)	`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@2.4.3 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

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 the plugin

The plugin configuration is comprised of options that are read by the CLI while generating and cleaning API docs.

note

See plugin configuration options for a more thorough reference.

The following is an example configuration to help get you started.

docusaurus-plugin-openapi-docs
plugins: [
  [
    "docusaurus-plugin-openapi-docs",
    {
      id: "openapi",
      docsPluginId: "<your docs plugin id>", // e.g. "classic" or the plugin-content-docs id
      config: {
        petstore: { // "petstore" is considered the <id> that you will reference in the CLI
          specPath: "examples/petstore.yaml", // path or URL to the OpenAPI spec
          outputDir: "api/petstore", // output directory for generated *.mdx and sidebar.js files
          sidebarOptions: {
            groupPathsBy: "tag", // generate a sidebar.js slice that groups operations by tag
          },
        }
      }
    },
  ]
],

Configuring the theme

To use the theme you"ll need to define it under themes in docusaurus.config.js:

docusaurus-theme-openapi-docs
themes: ["docusaurus-theme-openapi-docs"] // exports ApiItem and ApiDemoPanel

Finally, you"ll need to replace @theme/DocItem with @theme/ApiItem as your docItemComponent. Where you do this will depend on whether you are using @docusaurus/preset-classic or a standalone @docusaurus/plugin-content-docs to render your docs (see examples below).

note

The @theme/ApiItem component is designed to be a drop-in replacement for @theme/DocItem that supports rendering OpenAPI documentation while maintaining backwards compatibility with non-API docs. In other words, it can be used for rendering both API and non-API docs.

preset-classic example
presets: [
  [
    "classic",
    ({
      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" // add @theme/ApiItem here
      },
      blog: {
        showReadingTime: true,
        editUrl:
          "https://github.com/facebook/docusaurus/tree/main/packages/create-docusaurus/templates/shared/"
      },
      theme: {
        customCss: require.resolve("./src/css/custom.css")
      }
    })
  ]
]

plugin-content-docs example
plugins: [
    [
      "@docusaurus/plugin-content-docs",
      {
        path: "docs",
        breadcrumbs: true,
        routeBasePath: "docs",
        include: ["**/*.md", "**/*.mdx"],
        sidebarPath: "sidebars.js",
        docLayoutComponent: "@theme/DocPage",
        docItemComponent: "@theme/ApiItem", // add @theme/ApiItem here
      },
    ],
  ],

                                                           enabled).

tip

If you're configuring multiple docusaurus-plugin-openapi-docs instances use the -p or --plugin-id option to specify which plugin instance to run the commands against.

Options:
  -p, --plugin-id <plugin>  OpenAPI docs plugin ID.
  -h, --help                display help for command

Generating OpenAPI Docs

The following command will generate API docs for all of the OpenAPI specifications referenced in your docusaurus-plugin-openapi-docs config.

yarn docusaurus gen-api-docs all

The following command will generate API docs for a specific id:

yarn docusaurus gen-api-docs <id>

Example:

generating API docs for 'petstore'

yarn docusaurus gen-api-docs petstore

Cleaning API Docs

Occasionally you may need to clean and re-generate API docs, especially following changes to your OpenAPI specification(s).

The following command will clean all API docs referenced in your docusaurus-plugin-openapi-docs config.

yarn docusaurus clean-api-docs all

The following command will clean API docs for a specific id:

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.
