Configuration

To use the extension, we recommend you create a configuration file called .redocly.yaml and place it in the root directory of your workspace. If the extension detects that this file doesn't exist, it prompts you to create it automatically for the current workspace.

Here's an example of what your directory structure could look like:

├── workspace
│   ├── openapi-definitions
│   │   ├── production.yaml
│   │   └── test.yaml
│   ├── .redocly.yaml
│   ├── some-file.txt

The .redocly.yaml configuration file defines the criteria for validating OpenAPI definitions.

Add the following example contents to the file and save the changes:

Copy
Copied
apiDefinitions:
  main: path/to/your-openapi.yaml
  test: path/to/another-openapi.yaml
lint:
  extends:
    - recommended
  rules:
    tag-description: off
    operation-summary: error
    no-unresolved-refs: error
    no-unused-components: error
    operation-2xx-response: error
    operation-operationId: error
    operation-singular-tag: error
    no-enum-type-mismatch: error
    no-identical-paths: error
    no-ambiguous-paths: error

This will let you start working with the extension. You can modify the file at any point to control the behavior of the extension. When modifying the .redocly.yaml file, you must save it to disk for your changes to apply.

To learn more about built-in rules you can use, refer to the Redocly CLI documentation. The linting guide provides more information on how to configure the linter.

Note that you can add multiple paths to OpenAPI files under apiDefinitions, each in its own line with a custom, unique name as the key. Files listed in this section will be automatically validated by the extension when you open them in VS Code. Changes made to apiDefinitions are dynamically reflected in the preview panel.
