Here you'll learn how to create a plugin for Eta by creating a plugin that enables layout support.
Note: this tutorial was created before Eta got built-in layout support. This plugin is no longer necessary if you want to use layouts, but we're leaving this tutorial up because it is a helpful example
Feel free to publish NPM/Deno packages based on this code! A good rule of thumb is to begin plugin packages with eta_plugin_. For example, you could create a plugin called eta_plugin_layouts.
