Swagger Sample App

Overview

This is an example of using the source2swagger swagger generator. It demonstrates--with some modifications--how to use the source2swagger library to make a set of static JSON files which are swagger compliant.

Instead of having a tight server integration, this technique scans the source code and uses a ruby-based library to generate the swagger json files. It requires that you format your source comments appropriately so the model can be built.

To generate the swagger json

Run ./bin/gen-json.sh to run the (modified) source2swagger library. This sets the input file and output location, and also writes a api-docs file for the resource listing. After running this, you should see files in your public directory

To run the stub server

You can run the sinatra-based server as follows:

ruby src/pet_api.rb 4567

This will start a server listening on http://localhost:4567.

Browsing the docs

With swagger-ui by entering http://localhost:4567/api-docs in the URL.

How it works

After generating the json files, the single api class (pet_api.rb) has two additional routes. They are used to deliver the resource listing and api declarations:

  # respond to requests to /api-docs, and serve contents of ./public/api-docs
  get '/api-docs' do
    res = File.read(File.join('public', 'api-docs'))
    body res
    status 200
  end

  # respond to requests to /api-docs/:api (i.e. /api-docs/pet) and serve contents of ./public/:api
  get '/api-docs/:api' do
    res = File.read(File.join('public', params[:api].to_s))
    body res
    status 200
  end

Note! These paths (public, api-docs, api-docs/:api) are configured in the bin/source2swagger script! If you don't like the way it's configured, start there.
