Use the mounting feature in express instead http://expressjs.com/en/4x/api.html#app.onmount
api version ====
Wrapper for express routing methods to help with versioning apis
##Usage
>varapiv=require('api-version');>varapp=express();>varapi=apiv.version(app,'/api','v1');>varapi2=apiv.version(app,'/api','v2');>api.get('/user',function(){>});>api.post('/user',function(){>});>api2.get('/user',function(){>});>```>Since the routes were added using api instead of app, the routes turn out to be>```/api/v1/userand
/api/v2/user
