Introduction
In the age of digital music, a sleek and functional music player is essential. This tutorial walks you through creating a music player app using Angular and Tailwind CSS. With features like track navigation, a custom progress slider, and a curated playlist, this app is both visually appealing and highly interactive.
Key Features of Harmonic Beats
Track Navigation: Skip forward or backward between tracks.
Custom Progress Slider: Built with CSS for precise playback control.
Playlist Management: Display and select tracks from a scrollable list.
Error Handling: Alerts for playback issues.
Step-by-Step Guide to Building the App
1. Setting Up the Angular Project
Start by setting up an Angular project. If you don't already have Angular CLI installed, do so with:
npm install -g @angular/cli
Then create a new project:
ng new music-player
cd music-player
Install Tailwind CSS:
npm install -D tailwindcss postcss autoprefixer
npx tailwindcss init
Configure tailwind.config.js to include Angular components:
module.exports = {
content: [
"./src/**/*.{html,ts}",
],
theme: {
extend: {},
},
plugins: [],
}
Add Tailwind directives in src/styles.css:
@tailwind base;
@tailwind components;
@tailwind utilities;
2. Designing the UI with Tailwind CSS
Use Tailwind CSS to create a modern, responsive UI. Below is the HTML structure for the component:
<div class="w-full h-screen flex flex-col items-center justify-center p-6 bg-gray-800 text-white">
<h1 class="text-3xl font-bold mb-8">Music Player</h1>
@if (error()) {
<div class="bg-red-500 p-4 mb-4 rounded w-full max-w-md">
<div class="flex items-center">
<span class="material-icons mr-2">error_outline</span>
<div>
<h4 class="font-bold">Error</h4>
<p>{{ error() }}</p>
</div>
</div>
</div>
}
<!-- Current Track -->
<div class="text-center mb-4 w-full max-w-md">
<h2 class="text-2xl font-bold">{{ tracks[currentTrackIndex()].title }}</h2>
<p class="text-gray-400">{{ tracks[currentTrackIndex()].artist }}</p>
</div>
<!-- Custom Slider -->
<div class="relative mb-4 w-full max-w-md">
<input type="range" min="0" max="100" [value]="progress()" (input)="handleSeek($event)"
class="w-full h-2 bg-gray-600 rounded-lg appearance-none cursor-pointer slider-thumb" />
</div>
<!-- Player Controls -->
<div class="flex justify-center space-x-4 mb-6 w-full max-w-md">
<button (click)="handlePrevious()" class="btn">
<i class="fas fa-step-backward"></i>
</button>
<button (click)="handlePlayPause()" class="btn">
@if (isPlaying()) {
<i class="fas fa-pause"></i>
}
@else {
<i class="fas fa-play"></i>
}
</button>
<button (click)="handleNext()" class="btn">
<i class="fas fa-step-forward"></i>
</button>
</div>
<!-- Track List -->
<h3 class="text-xl font-semibold mb-2">Track List</h3>
<div class="h-[200px] w-full max-w-md rounded-md border border-gray-700 p-4 overflow-y-auto custom-scrollbar"
#trackListContainer>
@for (track of tracks; track $index) {
<div class="p-2 cursor-pointer hover:bg-gray-700 rounded-md"
[ngClass]="{ 'bg-gray-700': $index === currentTrackIndex() }" (click)="handleTrackSelect($index)">
<p class="font-medium">{{ track.title }}</p>
<p class="text-sm text-gray-400">{{ track.artist }}</p>
</div>
}
@empty {
<p class="text-gray-400">No tracks found</p>
}
</div>
</div>
3. Adding Interactivity
Define the logic in music-player.component.ts:
Handle Playback: Play, pause, and navigate tracks.
Update Progress: Monitor and display playback progress.
Error Handling: Provide user feedback for audio issues.

5. Deploy and Test
Use Angular CLI to serve the app locally:
