海外TECH	DEV Community	Building a music player application in react js	https://dev.to/aviyel/building-a-music-player-application-in-react-js-3ngd	Building a music player application in react jsIn this blog tutorial we are going to set up and build music player applications using react js from absolutely scratch There is an article specifically for you if you want to learn more about react React from absolute scratchWe will be building the UI and its functionalities from absolute ground level However before we begin the final version of the app should look something like this You can also check out the final live version of this application music player app react netlify appSo without any further ado let s get this party started Installing react applicationLet s get started with our first react application So the first thing you need to do is install Node js if you don t have it already installed on your system So for that visit Node js official site and install the correct and appropriate version We need node js because we can utilize the node package manager or NPM feature Now create a blank folder and open it inside the code editor of your choice For this tutorial I will be using VScode Next step let s open the integrated terminal and type npx create react app music payer react app this command will create the app inside the current directory and that application will be named as music payer react appIt usually only takes a few minutes to install Normally when downloading packages we would use npm to download them into the project but here we are using npx the package runner which will download and configure everything for us so that we can begin with an amazing template Now It s time to start our development server so for that simply type npm start and that s going to automatically open react app in the browser So this is how the boilerplate template appears right away Now it s time to investigate the file and folder structure provided by create react app There is a folder called node module that contains all of our node dependencies Then there s a public folder where the only thing that matters is the index html file So this appears to be a standard HTML file complete with head body and meta tags You ll notice a div with the id root inside our body tag followed by the fallback noscript tag which will be visible only if the user s browser has javascript disabled lt index html gt lt DOCTYPE html gt lt html lang en gt lt head gt lt meta charset utf gt lt link rel icon href PUBLIC URL favicon ico gt lt meta name viewport content width device width initial scale gt lt meta name theme color content gt lt meta name description content Web site created using create react app gt lt link rel apple touch icon href PUBLIC URL logo png gt lt link rel manifest href PUBLIC URL manifest json gt lt title gt React practice lt title gt lt head gt lt body gt lt noscript gt You need to enable JavaScript to run this app lt noscript gt lt div id root gt lt div gt lt body gt lt html gt So you re probably wondering where the content comes from Remember that All of our source code is contained within our source or src folder and react will inject it into the root div element Let s take a look at our src folder which contains some stylesheets javascript files and SVG files Now head over to our App js file App jsimport logo from logo svg import App css function App return lt div className App gt lt header className App header gt lt img src logo className App logo alt logo gt lt p gt Edit lt code gt src App js lt code gt and save to reload lt p gt lt a className App link href target blank rel noopener noreferrer gt Learn React lt a gt lt header gt lt div gt export default App In this case we re simply importing react from react and logo from our logo using standard javascript Following that we have a normal javascript function called APP and this function in react is known as a functional component and this function is returning a react element that looks like HTML but is actually an jsx as you can see there is a div tag with a className of APP and we can t say class by itself because the class is a reserved word in javascript so in jsx we have to use className Following that we have the header and then the image and notice on the image source that we have our logo which is actually a javascript variable that we imported at the top so in order to use the javascript within JSX we must surround it with curly brackets and then we have a paragraph an anchor tag and that is all for this component NOTE Because of the export we are able to extract the component and place it on the webpage Export appears at the bottom of the app js file indicating that we are exporting the App function So Now let s look at the index js file index jsimport React from react import ReactDOM from react dom import index css import App from App import reportWebVitals from reportWebVitals ReactDOM render lt React StrictMode gt lt App gt lt React StrictMode gt document getElementById root reportWebVitals So in this case we re importing react from react again and this time we re also importing react dom and then we re importing the CSS stylesheet file and finally we re importing App from App js which is the file we just discussed and there s service worker which is used to make your application work completely offline Then we invoke ReactDom render which accepts two parameters The first parameter is the jsx object and within jsx we can include our user defined components so react strict mode is a react defined component whereas App is a user defined component and the second parameter is document getElementById root which targets the root div in our index html file and is how we access the content in our webpage Note ReactDom renders our content into our root div located at our index html file Creating a music player application Let s create a simple music player application in react from the ground up but first let s create a prototype or mindmap of our final application So our final app will look something like this Before we begin building our projects we must first clean them up by removing some of the files provided by create react app Your src files should look like this after you ve cleaned them up Now within the public folder make another folder called songs and songs images and within that songs folder add all the songs that you want and inside the songs images add the cover images of that songs All the songs and songs images are available for download from hereReact music player app Github Now go to your App js file and create a useState because this hook will enable us to integrate the state into our functional component useState unlike state in class components does not work with object values If necessary we can use primitives directly and create multiple react hooks for multiple variables const state setState useState initialState Hooks in React must always be declared at the top of a function This also aids in the preservation of state between all rendering for the component Now change the songs initialization like the following illustration Copy and paste the code below into your App js file App jsimport React from react import useState useEffect from react import App css const App gt const songs setSongs useState title orries artist Peachy album Shiloh track orries year img src songs images orries Cover front e jpg src songs orries mp title oops artist potsu album oops track year img src songs images oops Cover front e jpg src songs oops mp title pm

Cover front e jpg src songs Can We Kiss Forever mp return lt div className App gt MusicPlayer lt div gt export default App Now within the src folder make another folder called components and within that folder make three components Player PlayerControls and PlayerDetails After adding the component it s time to install fontawesome library to our project So for that simply copy and paste the following code in package json and inside the dependencies and type npm install in your integrated terminal fortawesome fontawesome svg core fortawesome free solid svg icons fortawesome react fontawesome and also let s import the minified version of fontawesome css CDN link in the index html file located inside the public folder lt link rel stylesheet href gt Your final index html file should look somewhat similar to this index html lt DOCTYPE html gt lt html lang en gt lt head gt lt meta charset utf gt lt link rel icon href PUBLIC URL favicon ico gt lt meta name viewport content width device width initial scale gt lt meta name theme color content gt lt link rel stylesheet href gt lt meta name description content Web site created using create react app gt lt link rel apple

JavaScript to run this app lt noscript gt lt div id root gt lt div gt lt body gt lt html gt Let s head over to our PlayerControl components and add the following code This component will display the controls for the music player PlayerControls jsimport React from react import FontAwesomeIcon from fortawesome react fontawesome import faPlay faPause faForward faBackward from fortawesome free solid svg icons function PlayerControls props return lt div className music player controls gt lt button className skip btn onClick gt props SkipSong false gt lt FontAwesomeIcon icon faBackward gt lt button gt lt button className play btn onClick gt props setIsPlaying props isPlaying gt lt FontAwesomeIcon icon props isPlaying faPause faPlay gt lt button gt lt button className skip btn onClick gt props SkipSong gt lt FontAwesomeIcon icon faForward gt lt button gt lt div gt export default PlayerControls Now let s head over to our PlayerDetails components This component will list out all the details of the Songs PlayerDetails jsimport React from react function PlayerDetails props return lt div className music player details gt lt div className details img gt lt img className details img image src props song img src alt props song title gt lt div gt lt div class range gt lt div gt lt div className artist info gt lt h className details title gt props song title lt h gt lt h className details artist gt props song artist lt h gt lt div class line gt lt div gt lt div gt lt div gt export default PlayerDetails Finally it s time to update our Player component This will be the primary component through which we will make our application function The first step is to import useState useRef useEffect and the components we previously created and import it within our player components Player jsimport React useState useRef useEffect from react import PlayerDetails from PlayerDetails import PlayerControls from PlayerControls We discussed useState hook previously let s dive into useEffect hook By using this Hook you tell React that your component needs to do something after render React will remember the function you passed we ll refer to it as our “effect and call it later after performing the DOM updates To this effect we set the document title but we could also perform data fetching or call some other imperative API Placing useEffect inside the component lets us access the count state variable or any props right from the effect We don t need a special API to read it ーit s already in the function scope Hooks embrace JavaScript closures and avoid introducing React specific APIs where JavaScript already provides a solution useEffect the hook is somewhat similar to the life cycle methods that we are aware of for class components It runs after every render of the component including the initial render Hence it can be thought of as a combination of componentDidMount componentDidUpdate and componentWillUnmount If we want to control the behavior of when the effect should run only on initial render or only when a particular state variable changes we can pass in dependencies to the effect to do so This hook also provides a clean up option to allow cleaning up of resources before the component is destroyed basic syntax of the effect useEffect didUpdate We dived into useState and useEffect hooks So you might be wondering “what is useRef hook “ This hook simply returns a mutable ref object with the passed argument as its current property initialValue The returned object will be retained for the duration of the component s lifetime const refContainer useRef initialValue Let us jump right back into the code So inside the Player component utilize the two hooks useState and useRef hooks Player jsconst audioElement useRef null const isPlaying setIsPlaying useState false After that utilize the useEffect hook to implement the pause and play functionalityuseEffect gt if isPlaying audioElement current play else audioElement current pause Now Create a function that actually skips or forwards the songs const SkipSong forwards true gt if forwards props setCurrentSongIndex gt let temp props currentSongIndex temp if temp gt props songs length temp return temp else props setCurrentSongIndex gt let temp props currentSongIndex temp if temp lt temp props songs length return temp Finally add the following code inside the return statement lt p
