海外TECH	DEV Community	A Guide to Understanding Vue Lifecycle Hooks	https://dev.to/smpnjn/a-guide-to-understanding-vue-lifecycle-hooks-kdl	A Guide to Understanding Vue Lifecycle HooksLike other frameworks Vue has a number of lifecycle hooks which allow us to attach code to specific events that occur while a Vue application is being created or used for example when the component loads when a component is added to the DOM or when something is deleted Vue has a lot of lifecycle hooks and what can be confusing is what each one means or does In this guide we ll be covering what each lifecycle hook does and how to use them PrerequisitesIf you are unfamiliar with Vue you might want to check out my guide on creating your first Vue applications before doing this one Alternatively you can read my guide on creating a to do list in Vue if you are slightly more familiar with it Lifecycle Hooks in VueThe important thing to note here is that Vue has two paradigms when it comes to lifecycle hooks One is using the Compositions API something introduced in Vue and the other is the Options API which is the prototypical pattern of defining Vue components In this guide we ll start with the Options API and then build off that to show how things work in the compositions API Example of Options APIIf you are unfamiliar with the Options API it is the version of Vue that looks like the code below export default name Component Name data return phoneNumber mounted Lifecycle Hooks DiagramTo understand when each lifecycle hook fires let s look at a diagram Below an image depicts when each lifecycle hook fires Running a Lifecycle HookTo run any lifecycle hook with the Options API you can add it to your Javascript prototype For example if you want to use beforeCreate the first hook fired after a new component is detected you could add it like this export default name Component Name data return someData mounted Any code you want to fire immediately before the Options API loads up Now that we ve covered when the different hooks occur let s look at what each of them do and when they happen beforeCreate Called at the point the component is initialized data and computed properties are not available at this point It is useful for calling APIs which do not adjust the data of the component If you update data here it will be lost once the Options API loads up created Called after the instance has finished processing all state operations You have access to reactive data computed properties methods and watchers el which is where Vue stores the component HTML is not available yet since the DOM element is not created If you want to fire something like an API or update data you can do it here beforeMount This hook runs immediately before rendering occurs The template has been compiled so it is stored in memory but it has not been attached to the page yet None of the DOM elements have been created yet el is still unavailable at this stage This is not called when doing server side rendering of a site mounted The component is mounted and shown on the page el is now available so you can now access and manipulate the DOM from Vue This will only fire after all child components are fully mounted It s useful to use this when you want to do something to the DOM after it has loaded like perhaps change a particular element within it This is not called when doing server side rendering of a site beforeUpdate Sometimes you wil change data in your Vue component by updating it in a watcher or by a user interaction When you change data or cause a re render in your component an update event will fire Immediately before the re render occurs beforeUpdate will fire After this event the component will be re rendered and updated with the latest data You can use this hook to access the current state of the DOM and even update data from it This is not called when doing server side rendering of a site updated After an update is fired and the DOM has been updated to match the latest data updated will fire This happens immediately after the re render Now if you access el or anything else about the DOM content it will show the new re rendered version If you have a parent component the child component updated is called first followed by the parent updated hook This is not called when doing server side rendering of a site beforeUnmount If a component is removed then it becomes unmounted Before the component is completely removed beforeUnmount fires This event still has access to the DOM elements and anything else to do with the component This is useful in deletion events for example you can use this event to notify a server that a user has deleted a Node in a table for instance You still have access to this el as well as data watchers and methods if you need to use them This is not called when doing server side rendering of a site unmount Once completely removed the unmount event fires This can be used to clean up other data or event listeners or timers to let them know that this component no longer exists on the page You still have access to this el as well as data watchers and methods if you need to use them This is not called when doing server side rendering of a site Using Vue Lifecycle Hooks with the Composition APIIf you are used to using the Options API the above hooks will make a lot of sense If you ve mainly used Vue you may be more used to using the Composition API The Composition API is complementary to the Options API but we use hooks slightly differently Let s take a look at how it works created and beforeCreated are replaced with setup In the compositions API created and beforeCreated are not accessible Instead they are replaced with setup This makes sense since there is no Options API to load Any code you would have put in created or beforeCreated can now safely go in setup Hooks can be used alongside setup Hooks can still be used alongside setup in the same way they are in the Options API and this is pretty intuitive For example export default data return msg setup console log Component setup complete mounted console log this el However another way you may see this done is by defining the hooks within the setup function itself using composition API functions If we do things this way the hooks are named slightly differently beforeMount becomes onBeforeMount mounted becomes onMounted beforeUpdate becomes onBeforeUpdate updated becomes onUpdated beforeUnmount becomes onBeforeUnmount unmounted becomes onUnmounted These functions do exactly the same thing as I described in the previous section but they are called slightly differently All of these hooks must be called within either the setup function or in a setup script For example you must either run your hooks within a setup function like this export default setup All hooks must go here Or alternatively within a script tag with the setup attribute like so lt script setup gt All hooks must go within this setup script lt script gt As such if you want to call hooks using this methodology your code will look like this instead export default setup All hooks must go here onBeforeMount gt Code for beforeMount onBeforeUpdate gt Code for beforeUpdate There is no fundamental performance improvement or reason why this is better It is just another way of doing it and in some cases it ll make your code easier to read and maintain For other instances you might be better off using the Options API so use whichever you feel more comfortable with ConclusionThe Vue Lifecycle is quite complicated but it gives us a lot of tools to run code update data and make sure our components display the way we want them to In this guide we ve covered how it works when to use each part of the lifecycle and how the Compositions API works a little differently from the Options API in regards to lifecycle hooks If you ve enjoyed this you might enjoy some of my other Vue content Here are some relevant links How Vue Components WorkHow to use
