What are some examples of query parameters in Express?

Can you give me some examples of query parameters in Express?

Sure! In Express, query parameters are used to filter or modify the response. For example, you can use /users?age=25 to get users who are 25 years old.

What if I want to filter by multiple parameters?

You can do that by adding more parameters, like /users?age=25&gender=male to filter users who are 25 years old and male.

How do I access these parameters in my Express app?

You can access query parameters using req.query. For example, const age = req.query.age; will give you the age parameter.

Can you show me a code snippet for that?

Absolutely! Here's a simple example:

app.get('/users', (req, res) => {
  const age = req.query.age;
  // Your logic here
});
