Swagger helps in creating Restful Api, I get that. Where would you use LoopBack, is this another tool for creating Rest api. LoopBack has support swagger 2.0. I am confused here, can they be used interchangeably.
回答1:
Swagger is a documentation framework. If you attach the appropriate annotations to your code, it produces a "live" documentation site that lets users see all your REST services in a visual way, including their request and response formats, with the ability to execute sample calls.
Loopback is a framework that helps you actually write the REST services themselves.
回答2:
Swagger is a powerful open source framework backed by a large ecosystem of tools that helps you design, build, document, and consume your RESTful APIs
You can use the editor , to build the REST specification, without coding, then you use the Swagger generator to convert this human readable file, into real code on more than 10 languages, you can auto generate server and clients.
