Travel Planning App API using Node & Express.js

In this article, we’ll walk through the step-by-step process of creating a Travel Planning App With Node and ExpressJS. This application will provide users with the ability to plan their trips by searching for destinations, booking flights and hotels, submitting reviews, receiving notifications, sharing their trips on social media, and processing payments.

Prerequisites:

• NodeJS
• ExpressJS
• MongoDB

Approach to Create Travel Planning App API using Node and ExpressJS:

• Identify key features like user authentication, booking flights/hotels, reviews, notifications, and payments.
• Install Node.js, npm, and ExpressJS.
• Create a new project directory and initialize it.
• Implement features like user authentication, booking, review submission, and payment processing using Express.js controllers and routes.
• Integrate third-party APIs for flight/hotel booking, implement notifications, and enable trip sharing on social media.

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 body-parser bcrypt jsonwebtoken 

Step 3: Create folders for different parts of the application such as models, controllers, 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, Trip, Booking, Review, Notification, and Payment.

Step 5: Create controller functions for each feature such as searchDestinations, bookFlight, bookHotel, submitReview, sendNotification, shareTrip, and processPayment. Implement authentication middleware (authenticate) to protect routes that require authentication. Define route handlers for each feature in separate route files (authRoutes.js, tripRoutes.js, bookingRoutes.js, etc.).

Project Structure:

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

"dependencies": {
 "express": "^4.18.2",
 "mongoose": "^8.2.1",
 "body-parser": "^1.20.2",
 "bcrypt": "^5.1.1",
 "jsonwebtoken": "^9.0.2"
}

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

Start your server using the following command:

node app.js
