Issue with ES6 on 'npm start' #200

Closed iamwhitebox closed 8 years ago

It seems that there is a transpilation error in the controllers while running npm start, here is a snapshot of the error:

/Users/jeffreyjones/Sites/node-express-mongoose-demo/app/controllers/users.js:8 const { wrap: async } = require('co'); ^

check your node version.It should be NodeJs >= 6.x

madhums commented 8 years ago

@nick-ChenZe that's right. @iamwhitebox make sure to have node >= 6.x. That will solve the issue you are facing.

@madhums Can you share some resource which explain what "const { wrap: async } = require('co');" statement is doing. I checked this https://github.com/tj/co repo but couldn't understand how it works. Also, can you share some more resources which let us understand the use of async, function pointers, etc in multiple controllers.
