The Vue.js component lifecycle includes several key stages:

  • beforeCreate — initialization, data and events are not yet available.
  • created — data and methods are available, but the DOM is not yet created.
  • beforeMount — before the component is mounted to the DOM.
  • mounted — the component is mounted, and you can work with the DOM.
  • beforeUpdate — before reactive data updates.
  • updated — after the DOM has been updated.
  • beforeUnmount (Vue 3) / beforeDestroy (Vue 2) — before the component is removed.
  • unmounted / destroyed — after the component has been removed.

I often used mounted for initializing third-party libraries and API requests, created for preparing data, and beforeUnmount for cleaning timers or unsubscribing from events.
