### Middleware

A topic you will see discussed frequently is "middleware". If you're not familiar with that term, we suggest you start out by reading a few of these articles:

* [Writing Handsome Golang Middleware](http://laicos.com/writing-handsome-golang-middleware/) _2015-05-05_

## Toolkits and Frameworks

Before you decide to adopt a third party web framework or toolkit, keep in mind that the Go standard library provides all of the tools you need to build a sophisticated, modern web application. Keeping with Go's preference for simplicity and composability over complexity and magic, we suggest you [see how far the standard library can take you](http://golang.org/doc/articles/wiki/).

If you decide you need a bit more infrastructure, start by looking at some of the toolkits and libraries available.
