Vue3 + APIs

VueJS is a modern JavaScript frontend framework. Many popular websites use it for simplicity and performance every day. Vue offers a wide range of features to customize behavior, extend it, and use it for a variety of projects.

In this course, you will learn about some of the advanced features of Vue by learning all about Vue’s lifecycle hooks, reusing code, handling events, and creating custom form controls. You’ll then cover advanced templating concepts before learning about internationalization and gaining a deeper understanding of Vue. Then, you’ll learn how to create complex applications with Vuex and your own plugins, along with state handling communication with APIs. At the end, a selection of libraries and plugins is built as a more frequently reusable code for Vue.

This course requires a basic understanding of Vue to take full advantage of its contents. The practical examples discussed in this course will give you an edge in developing cleaner reusable code efficiently.

Advanced VueJS: Build Better Applications Efficiently

**Directives** let us attach encapsulated logic to otherwise unrelated components. Unlike mixins or even renderless components, they don’t imply any relationship between the components that use them. Directives are independent.

Vue offers many different directives, such as `v-slot` for using slots, and `v-model` for `@input` and `:value`, which is syntactic sugar. In addition, there are many more directives, such as `v-if`, `v-for`, and `v-bind`.

## How to define custom directives

We can define custom directives via `Vue.directive()`. The method takes two arguments—the name of the directive and an object of options or a function. The name of the directive defines how we can use the directive. For example, if we give our custom directive the name `logger`, we can use it as `v-logger`.

The second parameter, the directive options, can either be a function or an object that defines several hooks with the same signature as the single function. Vue’s TypeScript definitions for the directive function show us which parameters these functions receive from Vue.
