Compare/Contrast Koa with Express

Koa is known as being a lightweight framework created by the Express team, for Node.js, running on V8.

• For both, you require the framework and use app.listen on the server.
• Koa uses ES6 generators and yield next()
• Koa uses this.request and this.response while Express uses (req,res)
• Koa does not have a built-in router, while Express does.
• Koa requires a separate middleware to handle routes.
• Koa does not use callbacks, while Express does.
• Koa has built-in error handling, while Express does not.
• Koa and Express both use the same method calls:

.get()
.put()
.post()
.delete()

There are pros and cons to Koa and Express. The freedom of choice is yours!
