海外TECH	DEV Community	Create A Custom Audio Player Component Using React/Next.js, Tailwind & Howler	https://dev.to/designly/create-a-custom-audio-player-component-using-reactnextjs-tailwind-howler-pgd	Create A Custom Audio Player Component Using React Next js Tailwind amp HowlerReact is a popular front end framework used by developers around the world to build web applications One of the key advantages of React is its ability to create reusable components that can be easily shared across different parts of a project or even between projects However building custom React components can be a challenging task especially if you re not familiar with the tools and libraries that are available In this tutorial we will explore how to create a custom React component that combines the power of Tailwind CSS for styling and Howler for audio playback Tailwind CSS is a popular utility first CSS framework that allows developers to easily style their components using pre defined classes while Howler is a fast and lightweight JavaScript library for audio playback We ll start by setting up a new React project and installing the necessary dependencies We ll then create a new custom component that will render an audio player interface allowing the user to play pause and stop an audio file We ll use Tailwind CSS to style the interface and Howler to handle the audio playback functionality The AudioPlayer ComponentIf you re relatively new to React then you ve probably only dealt with functional components FCs are great for small sized components but for larger more complex interfaces you ll want to use a full fledged React Component class In this example I use FCs for the smaller bits and a class for the player itself import React from react import ReactHowler from react howler import raf from raf import ImVolumeMedium from react icons im import FaPlay FaStop from

to play and stop audio tracks adjust the volume seek through the track and change the playback rate It also uses raf short for requestAnimationFrame to schedule and synchronize animations and updates with the browser s rendering engine This technique is commonly used for performance optimization and smoother animation as it allows the browser to schedule the update for the next frame usually at frames per second and avoids overloading the browser with too many updates in a short period of time In this specific code raf is used to repeatedly call this renderSeekPos when the player is playing which updates the seek position on the seek bar This creates a smooth animation effect and prevents the update from happening too frequently or too infrequently We use several state variables to keep track of the player s current state such as whether the audio is playing or not whether the audio is muted the current volume level and the current seek position Also several event handlers are there to handle user interaction with the audio player such as when the user toggles play or stop mutes or unmutes the audio adjusts the volume or seek position and changes the playback rate The component also uses some custom components such as Loading to show a loading spinner when the audio is loading Switch to toggle the loop mode and TimeItem to display the current time and duration of the audio track Please visit the repository link at bottom for the code for those items LinksGitHub RepoDemo PageThank you for taking the time to read my article and I hope you found it useful or at the very least mildly entertaining For more great information about web dev systems administration and cloud computing please read the Designly Blog Also please leave your comments I love to hear thoughts from
