      <p>I was recently explaining and demonstrating Nix and direnv to a colleague and showing how, when I moved into a directory, new packages or different versions of packages became available.</p>

      <p>If I left the directory, I was reverted back to my global packages and versions.</p>

      <p>In this demonstration, I was showing how I can have different versions of PHP and node for a particular project - replacing a lot of what I'd previously used tools like Vagrant and Docker for.</p>

      <p>I came up with a comparison between Nix and nvm - the node version manager - a tool that allows you to install multiple versions of nodejs and switch between them.</p>

      <p>Using Nix and direnv is more seamless, but it works for everything.</p>

      <p>I'm able to switch versions of PHP, MySQL, MariaDB, PostgreSQL or anything else I need with Nix.</p>

      <p>Not just node, and without needing containers.</p>
