HTTP Request Methods

71

#description

Node.js provides a built-in module for making HTTP requests to another server. The HTTP module can be used to issue HTTP requests with various methods, such as GET, POST, PUT and DELETE, while accessing data from different resources.

HTTP Request Methods are the verbs that HTTP clients use to send requests to servers. They tell the server what action to perform on the resource that the client is referring to.

Here are the most commonly used HTTP Request Methods:
  1. GET: The GET method is used to retrieve information from the server, specified by a URL. The server responds with the requested data, if it exists.
  1. POST: The POST method is used to submit an entity to the specified resource, often resulting in a change in server state. This could be used for submitting form data to the server, for example.
  1. PUT: The PUT method is used to update an existing resource, identified by a URL. The client will usually send the entire resource with any updates to the server.
  1. DELETE: The DELETE method is used to delete a specified resource. The server will usually respond with a 200 OK status code if the resource was successfully deleted.

These are only a few examples of HTTP Request Methods, but there are several others, like HEAD, OPTIONS, CONNECT, PATCH, and more that you can use depending on your needs. Understanding how to use HTTP Request Methods in Node.js is essential for building effective web applications.
