Spectral is a flexible JSON/YAML linter for creating automated style guides, with baked in support for OpenAPI (v3.1, v3.0, and v2.0), Arazzo v1.0, as well as AsyncAPI v2.x.
Spectral, being a generic YAML/JSON linter, needs a ruleset to lint files. A ruleset is a JSON, YAML, or JavaScript/TypeScript file (often the file is called .spectral.yaml for a YAML ruleset) that contains a collection of rules, which can be used to lint other JSON or YAML files such as an API description.
Linting isn’t just about validating OpenAPI or JSON Schema documents against specifications. It’s for enforcing style guides to ensure that your APIs are consistent, valid, and of high quality.
This is free and open source software.
Features include:
- Custom Rulesets: Create custom rules to lint JSON or YAML objects.
- Ready-to-use Rulesets: Validate and lint OpenAPI v2 & v3.x, AsyncAPI, and Arazzo v1 Documents.
- API Style Guides: Automated API Style Guides using rulesets improve consistency across all your APIs.
- Ready-to-use Functions: Built-in set of functions to help create custom rules. Functions include pattern checks, parameter checks, alphabetical ordering, a specified number of characters, provided keys are present in an object, etc.
- Custom Functions: Create custom functions for advanced use cases.
