Get Route Parameter Input from the Client
Problem Explanation
If someone tells you to build a GET or POST endpoint you would achieve the same using app.get(...) or app.post(...) accordingly.
Hints
Hint #1
In order to get route parameters from a POST request, the general format is as follows:
app.post("/:param1/:param2", (req, res) => {
// Access the corresponding key in the req.params
// object as defined in the endpoint
var param1 = req.params.param1;
// OR use destructuring to get multiple parameters
var { param1, param2 } = req.params;
// Send the req.params object as a JSON Response
res.json(req.params);
});
