What is the HTTP PATCH method?

The HTTP PATCH method is a request method used to make partial modifications to an existing resource. It’s similar to the HTTP PUT method, which is used to create a new resource or overwrite a representation of the target resource that is known by the client. However, the PATCH method is used to modify only a part of the resource, rather than replacing the entire resource.

How does the HTTP PATCH method work?

The HTTP PATCH method works by sending a request to the server with the changes that need to be made to the resource. The server then applies those changes to the resource and returns a response to the client. The PATCH method is useful when you want to update only a few fields of a resource without replacing the entire resource.

Advantages of using the HTTP PATCH method

The PATCH method in HTTP is used to partially update a resource on the server. It allows you to send only the data that needs to be updated, rather than sending the entire resource. This can be advantageous in situations where you want to make small, specific changes to a resource without having to resend the entire resource.

Advantages of using the HTTP PATCH method include:

  1. Efficiency: PATCH allows for more efficient use of network resources by sending only the changes that need to be made, reducing the amount of data transmitted.
  2. Partial Updates: PATCH enables you to update specific parts of a resource without affecting the rest of the resource, providing granular control over updates.
  3. Idempotent: When used properly, PATCH requests are idempotent, meaning that multiple identical requests will produce the same result as a single request, reducing the risk of unintended side effects.

These advantages make HTTP PATCH particularly useful for specific use cases where only a subset of resource data needs to be updated.

Disadvantages of using the HTTP PATCH method

There are also some disadvantages to using the HTTP PATCH method, some of the disadvantages of using the HTTP PATCH method are:

When to use the HTTP PATCH method

The HTTP PATCH method is best used when you want to update only a few fields of a resource without replacing the entire resource. It’s also useful when you want to update a resource that has multiple fields, but you only have access to some of those fields. For example, you might want to update a user’s email address without changing their password.

How to use the HTTP PATCH method

To use the HTTP PATCH method, you need to send a request to the server with the changes that need to be made to the resource. The request should include a JSON patch document that describes the changes that need to be made. The server will then apply those changes to the resource and return a response to the client.
