Vue.js is a popular JavaScript framework that enables reactive and flexible user interfaces (UI). It uses a reactive data binding system, which makes it easy to build complex applications with multiple components.
Vue.js Hooks are a powerful feature of Vue.js that allows you to use the state and context of your Vue.js components. Vue.js Hooks provide a simple way to add lifecycle methods, computed properties, and watch properties.
Vue.js Hooks are simple JavaScript functions that let you use a component's state and context in a more streamlined way. In Vue.js Hooks, you can easily define new reactive properties, access existing ones, and even create new methods.
Vue.js Hooks are divided into two separate categories: Composition API Hooks and Options API Hooks.
Composition API Hooks are new Vue.js Hooks that were introduced in Vue.js 3. They are a powerful new feature that allows you to create more detailed and complex reusable logic in your Vue.js components.
Below are some Composition API Hooks that are commonly used:
setup - It is the first hook to be executed before the creation phase. It will only be executed once.
computed - This hook is used to define a computed property that is based on other reactive properties of your component.
watch - This hook is used to monitor changes in your reactive properties.
provide and inject - These hooks are used to enable the sharing of data and dependency injection across your application.
Options API Hooks are the original hooks that were introduced in Vue.js 2. They are still in use in Vue.js 3 but are not recommended because of their limitations and complexity.
Below are some Options API Hooks that are commonly used:
data - It is used to initialize the data properties for your component.
created - It is one of the most commonly used hooks in Vue.js. This hook is executed once the component has been created.
mounted - This hook is executed once the component has been mounted on the DOM.
updated - This hook is executed when your component’s reactive data changes.
Vue.js Hooks provide a wide range of benefits and are a must-have in any Vue.js application. By using them, you can make your code more efficient, easier to read, and much simpler to maintain.
So, if you are starting with Vue.js, Vue.js Hooks are the perfect starting point for you. Start implementing them in your applications and see the benefits for yourself.
