Get Route Parameter Input from the Client |
Get Route Parameter Input from the Client
If someone tells you to build a GET or POST endpoint you would achieve the same using app.get(...)
or app.post(...)
accordingly.
Hint
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.parameter1;
// OR use destructuring to get multiple paramters
var { param1, param2 } = req.params;
// Send the req.params object as a JSON Response
res.json(req.params);
});
Solution
app.get("/:word/echo", (req, res) => {
const { word } = req.params;
res.json({
echo: word
});
});
