Empty URL parameters can be handled in Node.js using Express by checking if the parameter exists and then assigning a default value if it is empty. Here is an example:
app.get('/users/:id', (req, res) => {
const id = req.params.id || 'default';
// handle the ID
});
In this example, if the id
parameter in the URL is empty or not provided, it will default to the string 'default'
. This way, we can handle the scenario where the parameter is empty without causing errors in our code.
