feat: Add match method

[getspooky]

Sometimes you may need to register a route that responds to multiple HTTP verbs.
You may do so using the match method.
example :
app.match(['get','post'], '/' ,function(req,res) { console.log(req.method); });

Hello, and thanks for your pull request! We actually have a nice API for doing this registration: The Route object 😃 :

app.route('/')
  .get(function(req,res) { console.log(req.method); })
  .post(function(req,res) { console.log(req.method); })

You can also type your method only once by using a function reference:

function handleRequest (req,res) { console.log(req.method); }

app.route('/')
  .get(handleRequest)
  .post(handleRequest)

For more information, see our route documentation: http://expressjs.com/en/api.html#app.route

Hello and thank you for responding 😉
Sometimes method chaining makes code more readable, but if you get carried away, it can make it less readable and there is no need to chain the methods that handle the same function.

function handleRequest (req,res) { console.log(req.method); }
app.route('/')
  .get(handleRequest)
  .post(handleRequest)
  .put(handleRequest)

I think the match method could solve this problem:

app.match(['get','post','put'], '/' ,function(req,res) {
 console.log(req.method);
 });

Hm. I have never quite seen in the wild the ability to use the same function for different methods. Can you provide some use cases for even needing that to be built into the framework? It seems unlikely a handler to just log the method would be a use case.

I would suggest opening a new issue with your proposal and provide some great examples of what you would have to write in the real world without this helper so we can better understand the utility of it. As in, make the case in an issue to add it :)

On the surface, this PR doesn't add anything a user cannot already do with our route API, and I'm unsure what kind of handlers would exist that could handle both a GET, POST, and PUT all together without ended up with a switch internally to do different actions based on the method.

Hi @getspooky! This request seems similar to #4181.

I agree with @dougwilson, the best option here is to use app.route but in case that you need a switch approach I recommend the following (DRY):

app.all('/', (req, res) => {
    const validMethods = ["GET", "POST"];
    const { method }  = req
    if (validMethods.contains(method)) {
        return res.send(`Current method: ${method}`)
    }
    res.status(405).send() //405 Method Not Allowed
})
