Docusaurus OpenAPI Doc Generator

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.

Generating OpenAPI Docs

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

1yarn 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:

1yarn docusaurus gen-api-docs <id>

Example:

1yarn 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:

1yarn 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.

1yarn docusaurus clean-api-docs <id>

Example:

1yarn 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:

1yarn docusaurus gen-api-docs:version <id>:all

Example:

1yarn 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.
