Spectral

Spectral is a programmable linting engine and validation tool designed to enforce style guidelines and schema correctness within OpenAPI specifications and JSON configuration files. It functions as a rule-based validator that analyzes structured text files to ensure data consistency and adherence to predefined constraints.

The engine utilizes a configuration-driven execution model, allowing users to manage pluggable rule sets and integrate JSON Schema definitions. It supports the creation of custom function-based rules to define complex validation logic beyond static declarations.

The project provides tools for API design governance and documentation quality, automating the verification of OpenAPI and JSON/YAML documents. It employs rule-based abstract syntax tree validation and systematic document traversal to identify and report violations.

Features

  • API Governance Toolkits - Provides a toolkit for enforcing consistent style guidelines across multiple API definitions.
  • JSON-Schema - Integrates standardized JSON Schema definitions to enforce data types and required fields within documents.
  • OpenAPI Specification Linters - Checks OpenAPI documents for consistency and correctness to ensure they follow standard design rules.
  • Linters - Provides a utility to validate JSON and YAML documents against predefined or custom rules to ensure consistency.
  • AST Validation - Employs rule-based abstract syntax tree validation to identify and report structural violations in documents.
  • JSON Schema Validation - Automates the verification of structured JSON and YAML files to ensure adherence to schemas and prevent errors.
  • Linting Engines - Functions as a programmable linting engine that analyzes structured text files using declarative patterns.
  • API Documentation Linting - Improves API documentation quality by catching missing descriptions or incorrect formats during development.
  • AST Visitor Patterns - Utilizes the visitor design pattern to systematically traverse the document hierarchy and report violations.
  • Custom Validation Functions - Allows the use of external JavaScript functions to define complex validation logic beyond static declarations.
  • Configuration-Driven Rules - Uses local configuration files to determine which validation rules to apply and how to report errors.
  • Linting Rule Configurations - Provides a system for defining custom linting rule configurations to maintain standardization across files.
  • Pluggable Rule Sets - Supports modular collections of validation constraints that can be toggled or extended through configuration files.
  • API Design Tools - Linter for detecting errors in JSON and YAML API files.
  • API Specification Tools - Lints YAML or JSON files against custom rulesets.

How this analysis was created: This summary and feature list were written by an AI model that read the project's README and public documentation pages. Each feature links to the documentation it came from; stars, license and language come straight from the GitHub API. The model does not read the source code, and the analysis is refreshed when the project is re-analysed. Learn more on our About page.

    go-swagger is a toolkit for working with Swagger/OpenAPI 2.0 specifications in Go. It generates server, client, and CLI code from a specification document, and can also produce a specification by scanning annotated Go source code. The project includes a static validation engine that checks documents against the schema and project-specific rules, and a specification transformation pipeline that resolves, flattens, and merges documents. The toolkit generates both client and server code from the same specification, ensuring consistency in request and response handling. It also produces a command
