Hence so if we click on a button then value will change and again DOM will updated.
Updated():–To see the re-rendering of DOM events this call comes into picture. So this hook is considered after mount() hook. In other words we can say that in here data object is ready to connect with DOM model.īeforeUpdate():–This hook is invoked together with updated() hook when we make some changes in our DOM. Hence this the stage where $el css selector comes into picture. Mounted():–After template compilation becomes complete then the template is mounted on Virtual DOM using Vue instantiation process. Once the template is being compiled immediately the output of this stage is given to mount() stage. This callback is called by Vue system after observation of computedproperties,methods and watchers etc.īeforeMount():–This call back is really happened just for compilation of template. Just we Vue consider it as the beginning of program.Ĭreated():–Once the Vue instance is being created most of the data observation related task is automatically covered in this callback. Nothing much is happened in this callback. Each step and stage is described in easy way so you can understand the execution flow of the system callback hooks.īeforeCreate():–This callback hook is the starting point of Vue call backs system.
