expressjsHow do I access query parameters in Express.js?

In Express.js, you can access query parameters by using the req.query object. This object contains the query string parameters in the URL as key-value pairs. For example, if the URL is http://localhost:3000/search?q=express, then req.query will be:

{
  q: 'express'
}

To access a specific query parameter, you can use bracket notation, like so:

const query = req.query['q'];
console.log(query); // 'express'

In the code above:

• req is the request object
• req.query is the object containing the query string parameters
• req.query['q'] is the specific query parameter we are accessing
