One of the latest offerings in the Laravel ecosystem, Laravel Valet, was released this past week. It makes setup of new applications simpler and even allows tunneling back from the public web to a local system for easy sharing. In this post to his site Mohamed Said takes a look at the "magic" behind Valet and how it does what it does.

So yesterday Taylor Otwell and Adam Wathan released Laravel Valet, it's simply a tool that helps OS X users easily run their websites locally for development purposes, without the need to configure anything each time a new project needs to be created.

The idea behind valet is that it configures PHP's built-in web server to always run in the background when the operating system starts, then it proxies all requests to a given domain to point to your localhost 127.0.0.1

He starts by helping you get the tool downloaded (via Composer) and what happens when you run the valet install command. He gets into the detail of each piece that valet sets up:

• the OS X daemon to run the PHP built-in server
• the Valet configuration files
• Dnsmasq (a DNS server)

He then talks about how handles the requests for your local ".dev" sites and the "drivers" it uses to decide which site to serve up.
