海外TECH	DEV Community	Grilling Vue 3 Essentials on Pinia Skewers	https://dev.to/philipjohnbasile/grilling-vue-3-essentials-on-pinia-skewers-3noc	Grilling Vue Essentials on Pinia SkewersWelcome to our deep dive into the dynamic world of Vue the latest iteration of the progressive JavaScript framework that has taken the development community by storm Vue brings a plethora of exciting features and improvements that not only enhance the performance but also make the development process more efficient and enjoyable In this comprehensive guide we ll traverse the breadth of Vue from its novel Composition API to the core concepts of reactivity components directives and routing We will demystify these topics with plenty of code examples and useful tips ensuring you have a solid understanding by the end of your reading journey As we venture further we ll also touch upon state management in Vue and explore Pinia a nimble and intuitive alternative to Vuex We ll show you how to leverage Pinia s power to make your applications more robust and maintainable Whether you re a newcomer to Vue or a seasoned developer looking to upgrade your skills this guide is designed to equip you with the knowledge and confidence to build amazing Vue applications So buckle up and let s dive right in Basic Vue App Vue applications are initialized slightly differently from Vue Here s a basic Vue application import createApp from vue import App from App vue createApp App mount app This is how you create a new Vue application and mount it to an HTML element with id app Vue Component Here s an example of a simple Vue component import defineComponent from vue export default defineComponent name MyComponent data return message Hello Vue This code defines a new component called MyComponent The data function returns an object with the component s data Vue Props Props are custom attributes you can register on a Vue component import defineComponent from vue export default defineComponent name ChildComponent props message String In this code we re defining a prop message which expects a String value Vue Directives Vue js uses double braces as place holders for data Vue js directives are HTML attributes with the prefix v lt template gt lt div gt lt This will print the message data property gt lt p gt message lt p gt lt This will bind the title attribute of the p element to the message data property gt lt p v bind title message gt lt p gt lt This will conditionally render the p element only if showMessage is true gt lt p v if showMessage gt message lt p gt lt This will handle the click event calling the updateMessage method gt lt button v on click updateMessage gt Update lt button gt lt div gt lt template gt Vue Options API vs Composition API In Vue we have the new Composition API as an alternative to the Options API for organizing logic code in a component Here s a comparison Options API import defineComponent from vue export default defineComponent data return count methods increment this count Composition API import defineComponent ref from vue export default defineComponent setup const count ref function increment count value return count increment Both codes do the same thing increment a counter but the Composition API provides a more flexible way to compose component logic Vue Lifecycle Hooks Lifecycle hooks in Vue have slightly different names from Vue They are prefixed with on instead of using the before prefix and camelCase convention For instance beforeCreate becomes onBeforeMount in Vue import onMounted onUpdated onUnmounted from vue export default setup onMounted gt console log Component is mounted onUpdated gt console log Component is updated onUnmounted gt console log Component is unmounted Vue Computed Properties Computed properties allow you to declare a property that is used in the template and is dependent on other properties import computed from vue export default setup const firstName ref John const lastName ref Doe const fullName computed gt firstName value lastName value return firstName lastName fullName In the template you can use fullName and it will always display the current firstName and lastName concatenated Vue Watchers Watchers are useful for executing logic when a reactive property changes import watch ref from vue export default setup const count ref watch count newValue oldValue gt console log Count changed from oldValue to newValue return count This will log a message every time count is changed Vue Teleport Vue introduces the lt teleport gt component that allows you to define a component that is placed in one part of the DOM but is moved to another part of the DOM at render time lt teleport to body gt lt div v if isModalOpen class modal gt lt modal content gt lt div gt lt teleport gt This would render the modal element as a direct child of the body element even if the teleport component is nested deep within the DOM tree Vue Suspense Vue adds the lt suspense gt component that provides a better user experience while waiting for a component to load It displays some fallback content until the primary content is ready to be rendered lt suspense gt lt template default gt lt AsyncComponent gt lt template gt lt template fallback gt lt div gt Loading lt div gt lt template gt lt suspense gt In this example Loading will be displayed until AsyncComponent finishes loading Vue Provide Inject Provide and inject allow an ancestor component to serve as a dependency injector for all its descendants regardless of how deep the component hierarchy is as long as they are in the same parent chain import provide inject from vue const ThemeSymbol Symbol Ancestor componentexport default defineComponent setup provide ThemeSymbol dark Descendant componentexport default defineComponent setup const theme inject ThemeSymbol theme now equals dark Vue Emitting Custom Events In Vue custom events can be emitted using the emit function which is provided as the second argument to the setup function export default defineComponent setup props emit const onClick gt emit my event payload for the event return onClick You can listen to this event in a parent component like so lt MyComponent my event handleMyEvent gt Vue Directives Let s take a look at a custom directive example in Vue Let s make a directive that changes the color of the text in an element import directive createApp from vue const colorDirective directive beforeMount el binding vnode prevVnode el style color binding value createApp App directive color colorDirective mount app We can use this directive in a component like this lt div v color red gt This is a red text lt div gt Vue Plugins Creating a plugin in Vue involves exposing an install function Here s a basic example export default install app options app config globalProperties myPlugin plugin logic goes here You can then use your plugin like this import MyPlugin from my plugin createApp App use MyPlugin options mount app Vue Router Vue Router is the official router for Vue js Here s how you define routes and use them in Vue import createRouter createWebHistory from vue router import Home from views Home vue import About from views About vue const routes path name Home component Home path about name About component About const router createRouter history createWebHistory process env BASE URL routes export default router In your main js import createApp from vue import App from App vue import router from router createApp App use router mount app Vue State Management with Vuex Vuex is the official state management library for Vue js Here s a basic example Install Vuex with npm npm install vuex next saveStore creation import createStore from vuex export default createStore state count mutations increment state state count actions increment context context commit increment modules Usage in component import computed from vue import useStore from vuex export default setup const store useStore const count computed gt store state count function increment store dispatch increment return count increment Vue and Axios Axios is often used in Vue applications to make HTTP requests Here s how you might use it to fetch data from an API First install Axios npm install axiosThen use it in your component import reactive onMounted from vue import axios from axios export default setup const state reactive posts error null onMounted async gt try const response await axios get state posts response data catch error state error error return state Vue Render Function Sometimes you might need more control over the rendering process For these cases Vue provides a render function API import h from vue export default render return h div Hello Vue with Render function Vue Testing with Vue Test Utils Vue Test Utils is the official unit testing utility library for Vue js Here s a simple test for a component using Jest and Vue Test Utils First install necessary packages npm install save dev vue test utils jestThen a simple test could look like this import mount from vue test utils import Counter from Counter vue test increments count when button is clicked async gt const wrapper mount Counter wrapper find button trigger click await wrapper vm nextTick expect wrapper find div text toMatch Vue Mixins Mixins are a way to distribute reusable functionalities for Vue components Here s how you define and use a mixin Define a mixin objectconst myMixin created this hello methods hello console log hello from mixin Component that uses the mixinexport default mixins myMixin Now whenever this component is created it will log hello from mixin Vue Slots Slots provide a way to define placeholders in a component template that can be filled with content from a parent component Here s a simple example In the child component lt template gt lt div gt lt slot gt lt slot gt lt div gt lt template gt In the parent component lt template gt lt ChildComponent gt lt p gt This is some original content lt p gt lt ChildComponent gt lt template gt Vue Scoped Slots Scoped slots are a way to create slots that have access to properties from the child component In the child component lt template gt lt div gt lt slot name header user user gt user firstName lt slot gt lt div gt lt template gt lt script gt export default data return user firstName John lastName Doe lt script gt In the parent component lt template gt lt ChildComponent gt lt template header user gt lt p gt user firstName user lastName lt p gt lt template gt lt ChildComponent gt lt template gt Vue Transition amp Animation Vue provides various ways to apply transition effects to elements when they are added updated or removed from the DOM Here s an example lt template gt lt div gt lt button click show show gt Toggle lt button gt lt transition name fade gt lt p v if show gt Hello lt p gt lt transition gt lt div gt lt template gt lt script gt export default data return show true lt script gt lt style gt fade enter active fade leave active transition opacity s fade enter fade leave to opacity lt style gt Vue Custom Events Vue components can emit custom events with the emit method export default setup props emit const onClick gt emit myEvent Hello Vue return onClick In a parent component you can listen to this event with v on or lt ChildComponent myEvent handleMyEvent gt Vue Server Side Rendering SSR Vue js also supports building server rendered applications using vue server renderer However it s recommended to use Nuxt js when building server rendered applications with Vue js as it abstracts away a lot of the complexities of managing server rendered state and provides a higher level more opinionated framework with conventions Vue Renderless Components A renderless component is a component that doesn t render any of its own HTML but instead provides functionality to other components This is an advanced technique used to create reusable functions as components import ref from vue export default name RenderlessCounter setup slots const count ref const increment gt count value return gt slots default count count value increment Then you can use this renderless component like so lt RenderlessCounter v slot count increment gt lt button click increment gt You clicked me count times lt button gt lt RenderlessCounter gt Vue Composition API vs Options API Vue introduced a new way of writing components called the Composition API which is an alternative to the Options API used in Vue Here s the same component written with both APIs Composition API import ref from vue export default setup const count ref function increment count value return count increment Options API export default data return count methods increment this count Vue and TypeScript Vue has better TypeScript support than Vue You can write components like this import defineComponent from vue export default defineComponent name HelloWorld props msg String setup props TypeScript can infer the type of props console log props msg Vue and the Vue CLI The Vue CLI is a powerful tool that can help you bootstrap your Vue js applications It comes with a graphical user interface and it s flexible supporting a variety of configurations Install Vue CLI globally with npm npm install g vue cliCreate a new project vue create my projectServe the project cd my projectnpm run serve Vue Filters Vue filters are removed in Vue The recommended migration strategy is to use methods or computed properties instead import ref computed from vue export default setup const message ref hello const uppercaseMessage computed gt message value toUpperCase return message uppercaseMessage Vue Functional Components Functional components are a type of component that doesn t have any state and consists purely of a render function Functional components in Vue are written like this export default functional true render component logic Vue Custom Composition Functions With the Composition API you can create custom composition functions Here s an example of a custom hook that fetches data from an API import ref onMounted from vue import axios from axios export function useFetchData url const data ref null const isLoading ref true onMounted async gt try const response await axios get url data value response data catch error console error error finally isLoading value false return data isLoading Then you can use this function in a component import useFetchData from useFetchData export default setup const data isLoading useFetchData api data return data isLoading Vue Teleport The lt teleport gt component lets you control where your component s template is rendered in the DOM It s great for modals pop ups and other UI elements that need to break out of their container Here s an example of how to use it lt teleport to end of body gt lt div class modal gt This will be rendered at the end of the body lt div gt lt teleport gt Vue Suspense The lt Suspense gt component lets you wait for some condition and display some fallback content while waiting It s mostly used with async components Here s an example lt Suspense gt lt template default gt lt AsyncComponent gt lt template gt lt template fallback gt lt div gt Loading lt div gt lt template gt lt Suspense gt Vue Reactivity with Proxies Vue uses JavaScript Proxies for its reactivity system which allows it to track changes to objects and arrays better than Vue This is a low level detail and you normally won t have to worry about it but it s part of what makes Vue more powerful and flexible than Vue The teaching could go on indefinitely as Vue is a broad and deep framework that offers a multitude of functionalities and patterns But hopefully this guide has given you a solid foundation on which to build your Vue knowledge Remember to practice what you ve learned as practical application is key to solidifying these concepts Let me know if you have more questions or need information on other topics PiniaPinia is an alternative state management library for Vue js It aims to provide a simpler and more straightforward API than Vuex and it s fully compatible with the Vue Composition API First let s install Pinia npm install piniaCreating a store In Pinia instead of defining one big Vuex store you define multiple smaller stores Here s an example of a store import defineStore from pinia export const useCounterStore defineStore id counter state gt count actions increment this count reset this count Accessing the store In a Vue component you can access the store like this import useCounterStore from stores counter export default setup const counter useCounterStore return count counter count increment counter increment reset counter reset Using the store in the template And you can use the store in your template like this lt template gt lt p gt Count count lt p gt lt button click increment gt Increment lt button gt lt button click reset gt Reset lt button gt lt template gt Setting up Pinia You also need to install Pinia in your application import createApp from vue import createPinia from pinia import App from App vue const app createApp App app use createPinia app mount app That s the basics of Pinia It provides a simpler API and is more focused on the Composition API making it a great choice for Vue applications You can create more complex stores with actions that commit mutations and get state from other stores similar to Vuex Fetching data within a Pinia store Pinia stores can handle async actions which makes them great for fetching data import defineStore from pinia import axios from axios export const useUserStore defineStore id user state gt user null actions async fetchUser id const response await axios get api users id this user response data Computed properties in Pinia store Pinia also supports computed properties in the store Let s modify the previous example to include a computed full name import defineStore from pinia import axios from axios export const useUserStore defineStore id user state gt user null actions async fetchUser id const response await axios get api users id this user response data getters fullName return this user this user firstName this user lastName Accessing one store from another Sometimes you need to access data from one store inside another store You can do this by importing the other store inside the actions or getters import defineStore from pinia import useUserStore from user export const usePostsStore defineStore id posts state gt posts actions userPosts const userStore useUserStore return this posts filter post gt post userId userStore user id Testing Pinia stores Testing Pinia stores is straightforward because you can import the store functions directly into your test and call their actions and getters import useCounterStore from counter test increment increases count gt const counter useCounterStore counter increment expect counter count toBe Server side rendering SSR with Pinia Pinia supports server side rendering SSR out of the box It can serialize the state of your stores and then deserialize it on the client side so the client starts with the same state as the server Pinia provides a more idiomatic way to handle state in Vue with the Composition API and it s rapidly gaining popularity Its flexible and modular nature allows for a cleaner and more maintainable codebase for complex applications As always feel free to ask if you have any questions or need more information on a specific topic Resetting a store To reset a store in Pinia you can define a reset action in your store import defineStore from pinia export const useCounterStore defineStore id counter state gt count actions increment this count reset Resets the state to its initial state Object assign this state this initState The initState property holds a copy of the initial state and Object assign is used to replace the current state with the initial state Handling errors in a Pinia store When handling asynchronous actions in Pinia you ll want to have a way to handle errors You can do this with try catch import defineStore from pinia import axios from axios export const useUserStore defineStore id user state gt user null error null actions async fetchUser id try const response await axios get api users id this user response data catch error this error error Loading state in a Pinia store Often you ll want to display a loading spinner while fetching data You can add a loading state to your store import defineStore from pinia import axios from axios export const useUserStore defineStore id user state gt user null loading false error null actions async fetchUser id this loading true try const response await axios get api users id this user response data catch error this error error finally this loading false Reusing logic across stores Since Pinia stores are just JavaScript functions you can extract common logic into separate functions and reuse them across stores For instance if multiple stores have a loading state you could create a useLoading function export function useLoading return loading false startLoading this loading true stopLoading this loading false Then use it in a store import defineStore from pinia import useLoading from useLoading import axios from axios export const useUserStore defineStore id user state gt useLoading user null error null actions async fetchUser id this startLoading try const response await axios get api users id this user response data catch error this error error finally this stopLoading Mocking external dependencies in tests When testing Pinia stores you may need to mock external dependencies like API calls You can use libraries like jest mock to achieve this Here s an example import useUserStore from user import axios from axios jest mock axios test fetchUser fetches a user async gt const user id name John Doe axios get mockResolvedValue data user const userStore useUserStore await userStore fetchUser user id expect userStore user toEqual user And there you have it We ve journeyed together through the fundamentals of Vue and explored the intriguing world of Pinia We ve unpacked the power of the Composition API delved into creating dynamic components and understood how to manage state using Pinia This guide provides a solid foundation but remember that the world of web development is vast and continually
