In this tutorial, we will continue building our Admission Portal using Express.js and Node.js. In this sixth part, we will focus on creating endpoints for handling student applications.
Step 1: Set up Express.js Router
In this step, we will create a new file called studentRoutes.js in the routes folder, and set up the Express.js router for handling student-related routes.
Create a new file called studentRoutes.js in the routes folder.
Add the following code to set up the Express.js router:
const express = require(‘express’);
const router = express.Router();
module.exports = router;
Step 2: Create Endpoint for Creating Student Application
In this step, we will create an endpoint for creating a new student application.
Add the following code to studentRoutes.js to create an endpoint for creating a new student application:
router.post(‘/applications’, (req, res) => {
// Handle creating new student application
});
Step 3: Implement Creating Student Application
In this step, we will implement the logic for creating a new student application in the endpoint we created in the previous step.
Add the following code to studentRoutes.js to handle creating a new student application:
router.post(‘/applications’, (req, res) => {
const { name, email, dob, phone, address, program } = req.body;
// Validate input
if (!name || !email || !dob || !phone || !address || !program) {
return res.status(400).json({ message: ‘All fields are required’ });
}
// Create new student application
const newApplication = {
name,
email,
dob,
phone,
address,
program
};
// Save student application to database
// Replace this with actual database logic
// db.saveStudentApplication(newApplication);
res.status(201).json({ message: ‘Student application created successfully’, application: newApplication });
});
Step 4: Test Creating Student Application Endpoint
In this step, we will test the endpoint for creating a new student application using Postman.
Start the server by running npm start in the terminal.
Open Postman and create a new POST request to http://localhost:3000/applications.
Add the required fields (name, email, dob, phone, address, program) in the request body.
Click Send to test the endpoint.
You should receive a response with a success message and the new student application data.
In this tutorial, we continued building our Admission Portal by creating an endpoint for handling student applications. We implemented the logic for creating a new student application and tested the endpoint using Postman. In the next part, we will explore more features and functionalities for our Admission Portal.
