Vue.js is an open-source JavaScript framework used to create user interfaces and single-page applications. It is popular among developers for its simplicity and scalability, and its wide range of ready-made components and libraries. One of the most important aspects of any Vue.js development is understanding the lifecycle of a component. Knowing when a component is created, updated, or destroyed can be essential for making sure that your application works as expected. In this blog, we will take a deep dive into the Vue.js component lifecycle and explain each of the lifecycle hooks that are available.

We will also provide real-world examples of how these lifecycle hooks can be used to help control the workflow of your application. By the end of this blog, you should have a better understanding of the Vue.js component lifecycle and how you can use it to help develop more efficient applications. Let’s start by taking a look at the different lifecycle hooks available in Vue.js. The most commonly used lifecycle hook is the beforeCreate hook. This hook is triggered as soon as the component instance is created,
export default {
mounted() {
console.log(`the component is now mounted.`)
}
}
The beforeCreate hook is the perfect place to set up any data or logic that will be used throughout the component. Once this hook is finished, the created hook is then triggered. The created hook is the perfect place to set up any reactive data or values, as this is when the data and methods of the component are available. The next lifecycle hook is the mounted hook. This hook is triggered when the component is mounted onto the DOM and is the perfect place to set up any DOM manipulations or any third-party libraries that need to be used. The updated hook is then triggered when any reactive data is changed and is the perfect place to update any DOM elements or any logic that is dependent on the reactive data. The next lifecycle hook is the beforeDestroy hook. This hook is triggered before the component is destroyed, and can be used to clean up any code that was set up in the created or mounted hooks. Finally, the destroyed hook is triggered once the component is destroyed, and can be used to clean up any lingering code or logic.
