Sending 405 from express.js when there is a route match but no HTTP method match

Question

I\'m looking for a clean way to have my express app return 405 Method Not Allowed if a client sends a request that matches a mapped url route but does not match the mapped H

I have been doing it this way:

Say if you have GET and POST method handlers for /. You can wrap the path with app.route or router.route and assign the handlers accordingly.

    app.route("/").get((req, res) => {
            /* DO SOMETHING*/
    }).post((req, res) => {
            /* DO SOMETHING*/
    }).all((req, res) => {
            res.status(405).send();
    });

• http://expressjs.com/en/4x/api.html#app.route
• http://expressjs.com/en/4x/api.html#router.route

A request will get matched to the route and filtered through the handlers. If a handler is present, it will get handled as usual. Else, it will reach the all handler that will set the status code to 405 and ending the request.
