Nuxt layers are a great and intuitive way of sharing code across multiple Nuxt projects. There are many different use cases for creating a Nuxt layer. config. You can create a component library for use across multiple projects using the components directory.
You could create utility and composable libraries using the composables and utils directories. You could create Nuxt module presets, share standard setups across projects, create Nuxt themes, or even enhance code organization in a single project by implementing domain-driven design. The best part, if you already know how to create a Nuxt app, you essentially know how to create a Nuxt layer. In this course, let me show you the basics of how to create a Nuxt layer, and then we'll dive into a real-world example, seeing how I built a Nuxt layer to handle email concerns, like sending emails from multiple email providers and debugging emails via a mail catcher in development.
During the course, you'll learn how to bootstrap a new layer. You'll learn the different strategies for allowing consuming apps to configure your layer. You'll learn how to make imports from your layer both intuitive and functional via aliases as opposed to relative import paths. You'll learn how to use libraries like Hookable to communicate via events or hooks on the server side from your layer to the consuming app or even other layers.
you'll learn how to publish and share layers for use in different projects via NPM or via GitHub directly. Finally, as we look into the real world email layer, you'll get a firsthand glimpse at the flexibility that layers provide. I'll show you how to add custom dev tools that relate directly to the functionality of your layer so that whenever a project installs the layer, it'll automatically have related dev tools to go along with it. I'll show you how to keep up and manage docs inside of a mono repo right alongside your layer source code.
I'll show you how I used hooks, server-side utility functions, extendable classes, development-only server-side API endpoints, and more to make an email layer that's great for both production and development. By the end of the course, you'll not only be an expert in creating your own unique custom layers, but you'll also have a ready-to-go email layer to use in your projects.
