Vue 'deactivated' Lifecycle Hook


Example

Using the deactivated lifecycle hook to log every time the deactivated hook is called.

export default {
  data() {
    return {
      hookLog: []
    }
  },
  deactivated() {
    console.log("deactivated")
    this.hookLog.push("deactivated");
  }
}
Run Example »

Definition and Usage

The deactivated lifecycle hook runs when a cached component is removed from the DOM, but not destroyed.

A component is cached with the use of the built-in <KeepAlive> component.

After a cached component is created, it can be inserted and removed from the DOM many times, and every time such a cached component is removed from the DOM (but not destroyed), the deactivated lifecycle hook is called.

Note: The difference between the deactivated and unmounted hooks is that when a cached component is removed from the DOM (without being destroyed), only the deactivated hook is called.
