Introduction

Hey there! If you're reading this, you're probably wondering what HTTP methods are and how they work. Don't worry, you're not alone! HTTP methods can be a bit confusing for beginners, but they're actually a crucial part of how the internet works.

In this blog post, we'll take a closer look at HTTP methods and how we can use them in our code. We'll go over some common use cases and give you some tips and best practices for using HTTP methods effectively.

By the end of this post, you'll have a good understanding of what HTTP methods are and how you can use them.

What are HTTP Methods?

Professional Definition

According to MDN web docs:

HTTP defines a set of request methods to indicate the desired action to be performed for a given resource. Although they can also be nouns, these request methods are sometimes referred to as HTTP verbs.

HTTP stands for Hypertext Transfer Protocol, and it is the foundation of the World Wide Web. HTTP is a set of rules that define how computers communicate with each other over the internet.

HTTP methods, also known as HTTP verbs, are the actions that a client (such as a web browser) can request a server to perform.

Isn't it difficult to grasp? Don't worry, I'll explain everything to you in simple terms.

Easy Explanation

HTTP methods are a way for computers to communicate with each other over the internet. They allow you to do things like visit websites, upload pictures and update your social media profile.

There are four main HTTP methods that are commonly used in web development: GET, POST, PUT, and DELETE.

Let's understand this with an easy example.

Easy Example

Imagine you're at a restaurant, and you want to order some food. You can think of the HTTP methods as the different ways you can ask for what you want.

• GET is like when you ask the waiter for the menu. You're not ordering anything yet, you just want to see what options are available.

• POST is like when you order something new, like a special dish that's not on the menu. Maybe you're feeling adventurous and want to try something different!

• PUT is like when you ask the waiter to change something about your order. Maybe you want to swap out the fries for a salad or add an extra topping to your burger.

• DELETE is like when you want to cancel your order. Maybe you changed your mind and decided you don't want any food after all.

Wooh! That was a fantastic explanation, wasn't it? You should now understand what HTTP methods are.

HTTP methods in action: code examples

Now that you have a bit of background on HTTP methods, let's dive into some code examples.

1. GET Method

The GET method is used to retrieve data from a server or API. Here is an example of how you might use the GET method with the fetch() function in JavaScript:

fetch('https://example.com/api/users')
  .then(response => response.json())
  .then(data => console.log(data))
  .catch(error => console.error(error));

This code sends a GET request to the https://example.com/api/users endpoint and logs the response data to the console. The response.json() method parses the response data into a JSON object and the catch() method handles any errors that might occur.

2. POST Method

The POST method is used to create new resources on a server or API. Here is an example of how you might use the POST method with the fetch() function in JavaScript:

const data = { name: 'John', age: 30 };

fetch('https://example.com/api/users', {
  method: 'POST',
  body: JSON.stringify(data),
  headers: {
    'Content-Type': 'application/json'
  }
})
  .then(response => response.json())
  .then(data => console.log(data))
  .catch(error => console.error(error));

This code sends a POST request to the https://example.com/api/users endpoint with a JSON object containing the data for the new resource. The Content-Type header specifies that the data is in JSON format. The then() and catch() functions handle the response and any errors that might occur.

3. PUT Method

The PUT method is used to update existing resources on a server or API. Here is an example of how you might use the PUT method with the fetch() function in JavaScript:

const data = { name: 'John', age: 31 };

fetch('https://example.com/api/users/1', {
  method: 'PUT',
  body: JSON.stringify(data),
  headers: {
    'Content-Type': 'application/json'
  }
})
  .then(response => response.json())
  .then(data => console.log(data))
  .catch(error => console.error(error));

This code sends a PUT request to the https://example.com/api/users/1 endpoint, which updates the resource with the ID of 1. The Content-Type header specifies that the data is in JSON format. The then() and catch() functions handle the response and any errors that might occur.

4. DELETE Method

The DELETE method is used to delete resources from a server or API. Here is an example of how you might use the DELETE method with the

Sure! Here is the rest of the code example for the DELETE method:

fetch('https://example.com/api/users/1', {
  method: 'DELETE'
})
  .then(response => response.json())
  .then(data => console.log(data))
  .catch(error => console.error(error));

This code sends a DELETE request to the https://example.com/api/users/1 endpoint, which deletes the resource with the ID of 1. The then() and catch() functions handle the response and any errors that might occur.

Advantages of using HTTP methods in code

Improved efficiency

HTTP methods allow you to specify the action that you want the server to perform, which can help streamline communication between the client and server.

This can result in faster and more efficient data transfer, which can improve the overall performance of your web application.

Better organization of data

HTTP methods can help you organize your data in a logical and structured way. For example, you might use the POST method to create new resources, the GET method to retrieve data, the PUT method to update existing resources, and the DELETE method to delete resources. This can help you keep track of your data and ensure that it is being used and managed effectively.

Improved security

By using HTTP methods to specify the actions that are allowed on a server or API, you can help prevent unauthorized access or manipulation of data. This can improve the overall security of your web application.

Enhanced user experience

By using HTTP methods to efficiently manage and retrieve data, you can provide a smoother and more intuitive user experience for your users. This can lead to increased engagement and satisfaction with your web application.

Best practices for using HTTP methods

Here are a few tips and best practices to keep in mind when using HTTP methods in your code:

Use correct HTTP method

It is important to use the correct HTTP method for the action that you are trying to perform.

For example, use the GET method to retrieve data, the POST method to create new resources, the PUT method to update existing resources, and the DELETE method to delete resources.

This can help ensure that your web application is functioning correctly and efficiently.

Keep HTTP methods consistent

It is important to use HTTP methods consistently within your web application.

For example, if you use the GET method to retrieve data on one page, you should use the GET method to retrieve data on all other pages as well.

This can help ensure that your web application is easy to understand and use.

Use Methods along with Status Codes

HTTP status codes are used to indicate the status of a request or response. It is important to use HTTP status codes in combination with HTTP methods to provide more information about the request or response.

For example, if you are using the POST method to create a new resource, you might use the 201 Created status code to indicate that the resource was successfully created.

Use right HTTP methods to ensure security

It is important to use HTTP methods to specify the actions that are allowed on a server or API to prevent unauthorized access or manipulation of data and improve the overall security of your web application.

For example, you might use the GET method to allow users to retrieve data from an API, but use the POST method to limit the ability to create new resources to only certain users or administrators.

This can help ensure that only authorized users can perform certain actions on your server or API.
