1. gem install apiaryio // to use apiary cli
2. create a new api on apiary because you need the same.
3. hapi-swagger to generate swagger.json from routes
Example:
var swagger2apiary = require('swagger2apiary');
var gen = new swagger2apiary({token:'TOKEN from apiary',api_name:'NAME OF API',port:'PORT API RUNS ON'}}
gen.generate();
Note: Api must be running in order to gen docs because it pulls from localhost:PORT/swagger.yaml
Second Note: Currently apiary CLI only allows .yaml format for swagger documentation
