Vue Update Prop

Posted on  by admin
In this tutorial, you’ll learn how to watch props for changes in Vue.js.

When you pass data as a prop to a component it will be updated reactively. But if you need to call a method or perform some other actions on prop changes this code will help you.

If the yourProp changes, the yourPropChanged property will become true.

Answer originally edited into question by OP @Marek, copied here by the community.

Prop being mutated: "propRoomSelected". The value will actually change inside the component, but not outside the component.

The value of a parent property cannot be changed inside a component, and, in fact, the updated value will be lost if the parent re-renders for any reason.
