How to Build a Music Download Website with JavaScript196

In this tutorial, we'll build a music download website using JavaScript. We'll cover how to set up the server, handle file uploads, and create a user interface for browsing and downloading music. You'll need some basic knowledge of HTML, CSS, and JavaScript to follow along.

Prerequisites

installed on your system
A text editor or IDE
A music file to upload

Setting up the Server

We'll use Express as our web framework. Open your terminal and run the following command to create a new Express app:```
npm init express-generator my-music-app
```

This will create a new directory called "my-music-app" with all the necessary files for an Express app. Now, navigate to the "my-music-app" directory and run the following command to start the server:```
npm start
```

The server will be running on port 3000 by default. You can visit localhost:3000 in your browser to see the default Express welcome page.

Handling File Uploads

We need to handle file uploads in order to allow users to upload music to our website. We'll use the multer library for this. Install multer by running the following command:```
npm install multer
```

Now, modify the file to handle file uploads:```javascript
// ... existing code
// Import the multer library
const multer = require('multer');
// Set up the multer storage engine
const storage = ({
destination: './uploads/',
filename: (req, file, cb) => {
cb(null, () + '-' + );
}
});
// Initialize the multer upload object
const upload = multer({ storage });
// ... existing code
// Add a POST route to handle file uploads
('/upload', ('music'), (req, res) => {
// The file will be uploaded to the uploads/ directory
({ success: true, file: });
});
```

Creating a User Interface

Now, let's create a simple user interface for browsing and downloading music. Open the views/ file and add the following code:```html



Music Download Website





Upload





```

This HTML code creates a simple form for uploading music and a list to display the uploaded music files. We'll add the JavaScript code to handle the user interface in the next step.

JavaScript Code

Create a new file called and add the following JavaScript code:```javascript
// Fetch the music list element
const musicList = ('music-list');
// Function to display the uploaded music files
const displayMusicFiles = (files) => {
((file) => {
// Create a list item for each file
const li = ('li');
= ``;
// Add the list item to the music list
(li);
});
};
// Function to handle form submission
const handleFormSubmit = (e) => {
();
// Get the form data
const formData = new FormData();
// Send the form data to the server
fetch('/upload', {
method: 'POST',
body: formData
})
.then((res) => ())
.then((data) => {
// Display the uploaded file
displayMusicFiles([]);
})
.catch((err) => {
(err);
});
};
// Add event listener to the form
const form = ('form');
('submit', handleFormSubmit);
```

This JavaScript code handles the form submission and displays the uploaded music files in the list. When the user submits the form, the handleFormSubmit function is called. This function sends the form data to the server, which handles the file upload and returns the file information. The displayMusicFiles function is then called to display the uploaded file in the list.

Conclusion

In this tutorial, we built a basic music download website using JavaScript. We covered how to set up the server, handle file uploads, and create a user interface for browsing and downloading music. This website can be further enhanced by adding features such as user authentication, song streaming, and a search bar. Feel free to experiment with the code and build upon it to create your own custom music download website.
