Signup Form Using Node.js and MongoDB

Signup Form using Node.js and MongoDB allows users to register by storing their details securely in a MongoDB database. It connects the frontend form with a Node.js backend to handle validation and data storage.

Installations

Include a few packages for our Nodejs application.

npm install express --save

Express allows us to set up middlewares to respond to HTTP Requests.

npm install body-parser --save

To read HTTP POST data , you have to use the "body-parser" node module.

npm install mongoose --save

Mongoose is an object document mapping (ODM) layer which sits on the top of Node's MongoDB driver.

app.js

This is the main executable application file

Start the MongoDB, run:

node app.js

Go to the browser and open http://127.0.0.1:3000/

Fill the above form

This will add a record named "David Smith" in MongoDB. Let's have a check in MongoDB for the same record. The record is now saved in the "gfg" database in "details" collection.
