Defining a Route and Query in a Database

The route functions (get, post, put, delete) receives a callback function. That callback function receives two parameters (request and response) when someone access the route parameter. Request holds the information about incoming request while response is used to send a response back to the client. Each route combined with the port addess serves as an endpoint through which, the frontend can communicate to the backend server, send request and receive response. Provided below is the syntax through which we can create a route to submit the form data received from the frontend.

Node

app.post(‘/api/form’, (req, res) => {
const { username, password } = req.body;
const newForm = new Form({
username,
password
});

newForm.save((err, savedForm) => {
if (err) {
console.error(‘Error saving form:’, err);
res.status(500).json({ error: ‘Error saving form’ });
} else {
console.log(‘Form saved successfully:’, savedForm);
res.status(200).json({ message: ‘Form saved successfully’ });
}
});
});

Getting Started with MERN Stack

M (MongoDB) E (Express.js) R (React.js) N (Node.js) stack is a popular Javascript language-based stack for building full-stack applications, MongoDB, ExpressJs, and NodeJs being responsible for server building and React for client-side development. This article is going to be your guide if you want to get started with the MERN stack development.
