ExpressJS - HTTP Methods

The HTTP method is supplied in the request and specifies the operation that the client has requested. The below table summarizes the most used HTTP methods:

Method	Description
GET	The GET method requests a representation of the specified resource. Requests using GET should only retrieve data and should have no other effect.
POST	The POST method requests that the server accept the data enclosed in the request as a new object/entity of the resource identified by the URI.
PUT	The PUT method requests that the server accept the data enclosed in the request as a modification to existing object identified by the URI. If it does not exist then PUT method should create one.
DELETE	The DELETE method requests that the server delete the specified resource.

These are the most common HTTP methods. To learn more about them, head over to http://www.tutorialspoint.com/http/http_methods.htm.
