Redocly CLI

Command-line utility from @Redocly with OpenAPI superpowers. Build, manage and quality-check OpenAPI descriptions, configure and execute API governance, and publish beautiful API documentation. Supports OpenAPI 3.1, 3.0 and OpenAPI 2.0 (legacy Swagger format).

Usage

Node

npx @redocly/cli lint path-to-root-file.yaml

Alternatively, install it globally with npm:

npm install @redocly/cli -g

Then you can use it as redocly [command] [options], for example:

redocly lint path-to-root-file.yaml

Docker

To give the Docker container access to the OpenAPI definition files, you need to mount the containing directory as a volume. Assuming the OAS definition is rooted in the current working directory, you need the following command:

docker run --rm -v $PWD:/spec redocly/cli lint path-to-root-file.yaml

To build and run with a local image, run the following from the project root:

docker build -t redocly/cli .
docker run --rm -v $PWD:/spec redocly/cli lint path-to-root-file.yaml

Common tasks

Generate API reference documentation

Redocly CLI is a great way to render API reference documentation. It uses open source Redoc to build your documentation. Use a command like this:

redocly build-docs openapi.yaml

Your API reference docs are in redoc-static.html by default. You can customize this in many ways. Read the main docs for more information.

:bulb: Redocly also has hosted API reference docs, a (commercial) alternative to Redoc. Both Redoc and Redocly API reference docs can be worked on locally using the preview-docs command.

Lint an API description against a standard

Check your API meets the expected standards using lint to ensure quality in every version of your API. Our API linter is designed for speed on even large documents, so it's easy to run locally, in CI, or anywhere you need it. It's also designed for humans, with meaningful error messages to help you get your API right every time. Try it like this:

redocly lint openapi.yaml

Configure the rules as you wish. No JSONPath here, just type-aware expressions that understand the OpenAPI structure. You can either use the built-in rules to mix-and-match your ideal API standard, or break out the tools to build your own.

Format the output in whatever way you need, the stylish output is as good as it sounds, but if you need JSON or Checkstyle outputs to integrate with other tools, we've got those too.

Multiple files supported so you don't need to bundle your API description to lint it, just give the entry point and Redocly CLI does the rest.

Transform an OpenAPI description

If your OpenAPI description isn't everything you hoped it would be, enhance it with the Redocly decorators feature. This allows you to:

• Publish reference docs with a subset of endpoints for public use
• Improve the docs by adding examples and descriptions
• Adapt an existing OpenAPI description, and replace details like URLs for use on staging platforms

Data collection

This tool collects data to help Redocly improve our products and services. You can opt out by setting the REDOCLY_TELEMETRY environment variable to off.
