to remove manually added event listeners. This is a good place to access the existing DOM before an update, e.g.
If you want to wait until the entire view has been rendered, you can use vm.$nextTick inside of mounted:Ĭalled when data changes, before the DOM is patched. Note that mounted does not guarantee that all child components have also been mounted. If the root instance is mounted to an in-document element, vm.$el will also be in-document when mounted is called. This hook is not called during server-side rendering.Ĭalled after the instance has been mounted, where element, passed to app.mount is replaced by the newly created vm.$el. However, the mounting phase has not been started, and the $el property will not be available yet.Ĭalled right before the mounting begins: the render function is about to be called for the first time. At this stage, the instance has finished processing the options which means the following have been set up: data observation, computed properties, methods, watch/event callbacks. # beforeCreateĬalled synchronously immediately after the instance has been initialized, before data observation and event/watcher setup.Ĭalled synchronously after the instance is created.
The reason is arrow functions bind the parent context, so this will not be the component instance as you expect and this.fetchTodos will be undefined. This means you should not use an arrow function to define a lifecycle method (e.g. All lifecycle hooks automatically have their this context bound to the instance, so that you can access data, computed properties, and methods.
