Vuejs Events Emit

Introduction

As a front-end developer, you must have heard of Vuejs, one of the popular JavaScript frameworks. Vuejs provides a powerful way to manage components and events. In this article, we will discuss “Vuejs Events Emit” and how it can be used to send data between components.

Personal Experience

Before we dive into the technical details, let me share my personal experience with Vuejs Events Emit. I was working on a project where I had to pass data from one component to another. Initially, I was using props to pass the data, but it became difficult to manage as the project grew bigger. Then one of my colleagues suggested using events emit, and it was a game-changer.

What is Vuejs Events Emit?

Vuejs Events Emit is a way to send data from child components to parent components or vice versa. It is based on the publish-subscribe pattern, where the child component publishes an event, and the parent component subscribes to it. When the event is triggered, the parent component can access the data sent by the child component.

How to use Vuejs Events Emit?

The first step is to create an event in the child component using the $emit method. For example:

  this.$emit('eventName', data); 

The second step is to listen to the event in the parent component using the $on method. For example:

  Vue.component('parent-component', {   template: `    
   `,   methods: {    handleEvent(data) {     console.log(data);    }   }  }); 

Events in Vuejs

Vuejs has several built-in events that can be used to interact with components. Some of the most commonly used events are:

• click
• input
• submit
• keydown
• keyup

Conclusion

Vuejs Events Emit is a powerful way to send data between components in Vuejs.
