Open Source YAML Editors

Swagger Editor lets you edit Swagger API specifications in YAML inside your browser and to preview documentations in real time. Valid Swagger JSON descriptions can then be generated and used with the full Swagger tooling (code generation, documentation, etc). swagger-editor is a traditional npm module intended for use in single-page applications that are capable of resolving dependencies (via Webpack, Browserify, etc). swagger-editor-dist is a dependency-free module that includes everything you need to serve Swagger Editor in a server-side project, or a web project that can't resolve npm module dependencies. If you're building a single-page application, using swagger-editor is strongly recommended, since swagger-editor-dist is significantly larger.

The swagger module provides tools for designing and building Swagger-compliant APIs entirely in Node.js. It integrates with popular Node.js servers, including Express, Hapi, Restify, and Sails, as well as any Connect-based middleware. With swagger, you can specify, build, and test your API from the very beginning, on your laptop. It allows you to change and iterate your design without rewriting the logic of your implementation. Remember, one great thing about this approach is that all of the Swagger validation logic is handled for you, and all of the routing logic is managed through the Swagger configuration. You don't have to code (or recode!) any of that stuff yourself.
