I don't understand the advantages, could you clarify? - In what way are RESTyped definitions lighter? A Swagger definition is just a JSON or YAML file and can be used without shipping any additional code (e.g. by https://github.com/swagger-api/swagger-js https://github.com/swagger-api/swagger-js). - Swagger only requires a build step when the definition is used to generate code. Definitions can be distributed via NPM (e.g. https://www.npmjs.com/package/appveyor-swagger https://www.npmjs.com/package/appveyor-swagger). Edit: I realized you were talking about RESTyped being lighter/nobuild compared to Swagger Codegen specifically for TypeScript because it is written in TypeScript. Seems reasonable.
