A full-stack Swagger/OpenAPI editor with Monaco code editor, bidirectional conversion, and Go hexagonal backend.
This is a developer tool for editing Swagger/OpenAPI specifications and converting them to a normalised JSON format optimised for database storage. The Monaco editor (the engine behind VS Code) handles the code editing with full syntax highlighting and validation.
The conversion is bidirectional — you can go from OpenAPI 3.0.x or Swagger 2.0 (JSON and YAML) to the normalised format and back. This is useful when you need to store API specs in a database but want to present them in standard format.
The Go backend follows hexagonal architecture with ports and adapters. The GraphQL API uses gqlgen. Domain-driven design patterns keep the business logic clean and testable.
The frontend is React 19 + TypeScript with Vitest for testing. There are convenience scripts for setup, development, and building the full stack.
