Introduction of Phoenix Playground for Single-File Phoenix Applications

Wojtek Mach unveils Phoenix Playground, which is designed to make it easier to create and run single-file Phoenix LiveView apps. The concept builds on the ability introduced in Elixir v1.12 to install and use dependencies with `Mix.install/2`. Initially inspired by Gary Rennie's single-file Phoenix LiveView apps, Phoenix Playground aims to remove unnecessary boilerplate and streamline the process further. The platform supports live code reloading, integrates real-time server logs in the browser console, and includes built-in testing support for rapid prototyping and experimentation. Wojtek highlights how Phoenix Playground encapsulates all necessary components like endpoints and routers so developers can focus on building their apps. Users are encouraged to explore and experiment with this new tool for quick development and issue reproduction.
