Is it possible to pass data using a GET request?

Yes, it is possible.

Data is transmitted as parameters in the query string, appended to the URI after the ? symbol. Each parameter is a pair of "key=value", separated by the & symbol.

For example:

/users?id=123&status=active

Features and limitations of GET requests for data transmission:

• Data visibility: Parameters are visible in the URL, making them unsuitable for transmitting confidential information.
• URL length limit: Most browsers and servers have a maximum URL length limit, restricting the amount of data transmitted.
• Cacheability: Responses to GET requests can be cached.
• Idempotency: Performing the same GET request multiple times should have the same effect as doing it once. It should not change the server's state.
• Usage: Intended for retrieving data, not for sending data to change the server's state.

// Example of retrieving GET request parameters in Node.js using Express

const express = require('express');
const app = express();

app.get('/users', (req, res) => {
  const userId = req.query.id; // Getting the 'id' parameter
  const userStatus = req.query.status; // Getting the 'status' parameter

  console.log(`User ID: ${userId}, Status: ${userStatus}`);

  res.send(`Received data: ID=${userId}, Status=${userStatus}`);
});

app.listen(3000, () => {
  console.log('Server listening on port 3000');
});
