Music Playlist Manager with Node.js and Express.js

In this article, we’ll walk through the step-by-step process of creating a Music Playlist Manager with NodeJS and ExpressJS. This application will provide users with the ability to register, log in, create playlists, add tracks to playlists, update playlists, delete playlists, and manage their user profile. We'll also implement authentication using JWT (JSON Web Tokens) to secure the endpoints.

Prerequisites:

• NodeJS
• ExpressJS
• MongoDB

Approach to Create Music Playlist Manager with Node.js and Express.js

• Identify key features like user User authentication and authorization, Music Playlist Manager (CRUD operations), User playlist management, and Secure APIs using JWT (JSON Web Tokens).
• Install Node.js, npm, ExpressJS, and other project dependencies.
• Create a new project directory and initialize it.
• Ensure MongoDB is installed and running locally or use a cloud-based MongoDB instance. Create a database for your Music Playlist Manager.
• Create Mongoose models to represent User, Playlist, and Track entities.
• Implement Authentication, Authorization Middleware, Music Playlist Manager.

Steps to Create the NodeJS App and Installing Module:

Step 1: Create a NodeJS project using the following command.

npm init -y

Step 2: Install Express.js and other necessary dependencies.

npm install express mongoose jsonwebtoken bcryptjs body-parser express-validator dotenv

Step 3: Create folders for different parts of the application such as models, routes, and middleware. Inside each folder, create corresponding files for different components of the application.

Step 4: Set up a MongoDB database either locally or using a cloud-based service like MongoDB Atlas. Define Mongoose models for the data entities such as User, PlayList, Track.

Project Structure

The updated dependencies in package.json file will look like:

"dependencies": {
 "bcryptjs": "^2.4.3",
 "body-parser": "^1.19.0",
 "dotenv": "^10.0.0",
 "express": "^4.17.1",
 "express-validator": "^7.0.1",
 "jsonwebtoken": "^8.5.1",
 "mongoose": "^6.1.3",
 "nodemon": "^3.1.0"
 }

Example: Below is an example of Travel Planning App with NodeJS and ExpressJS.

Start your server using the following command:

node app.js
