Vue.js Components Fundamentals

Communication Between Components with Custom Events

We know how to pass data to a child component through props. In this lesson, we'll learn how to communicate from a child to a parent component through custom events.

We will use a custom event to notify the plan-picker of which plan has been selected, and make sure we have the right logic in place so the user can only select one plan at a time.

Important Note

Since Vue.js 3 became the default you must now specify version 2 when getting Vue from a CDN.
