How to create a global custom plugin in Nuxt.js

Nuxt.js supports three types of plugins: custom-built, Vue plugins, and external packages, with the tutorial focusing on creating a global custom plugin using Vue and JavaScript. The example plugin displays a birthday in the console of a Nuxt app, illustrating the process of building, defining, and registering the plugin, as well as subscribing the component to a Vuex store. The tutorial provides a detailed walkthrough of creating a toast component to display messages based on the store's state, using Vuex for state management, and injecting the plugin to be accessible across the app. The guide emphasizes the flexibility and customization potential of custom plugins, encouraging developers to adapt the example to suit their project needs and highlighting the importance of plugins when existing open-source options are insufficient.
