app.METHOD(path, callback [, callback ...])

Routes an HTTP request, where METHOD is the HTTP method of the request, such as GET, PUT, POST, and so on, in lowercase. Thus, the actual methods are app.get(), app.post(), app.put(), and so on. See Routing methods below for the complete list.

Routing methods

Express supports the following routing methods corresponding to the HTTP methods of the same names:

  • checkout
  • copy
  • delete
  • get
  • head
  • lock
  • merge
  • mkactivity
  • mkcol
  • move
  • m-search
  • notify
  • options
  • patch
  • post
  • purge
  • put
  • report
  • search
  • subscribe
  • trace
  • unlock
  • unsubscribe

The API documentation has explicit entries only for the most popular HTTP methods app.get(), app.post(), app.put(), and app.delete(). However, the other methods listed above work in exactly the same way.

To route methods that translate to invalid JavaScript variable names, use the bracket notation. For example, app['m-search']('/', function ....

The `app.get()` function is automatically called for the HTTP `HEAD` method in addition to the `GET` method if `app.head()` was not called for the path before `app.get()`.

The method, app.all(), is not derived from any HTTP method and loads middleware at the specified path for all HTTP request methods. For more information, see app.all.
