Server-side web frameworks

Building a web server like we just did is tedious and not scalable. There are a lot of things we need to implement, from routing to persisting data to rendering views. For such use cases, it's best to use a framework that can provide us with all the bells and whistles needed to quickly get started so we can focus on the application logic rather than spending time configuring and reinventing what others have already built.

Developers and even giant corporations, such as IBM, are betting that server-side Swift is the future by building frameworks in the form of Swift packages that make it very easy to build a web application. A few months after Swift was open sourced, one startup created a server-side framework called Perfect, which is very popular for building an entire server backend in Swift. IBM has spent a lot of effort creating Kitura, which is their take on a server-side swift framework that is lightweight and customizable, similar to express in Node.js or Sinatra in Ruby. Vapor is also a very popular framework with a lot of features.
