Handling PATCH Request

The update a response on the server we use 2 methods, The PATCH & PUT method.

PUT method is simply involves when the client modifies the entire resource

PATCH method involves modifying resource but in this case the client sends partial data that is updated without modifying the entire data

To update a movie on the list we use the ID to target a specific movie. To achieve this we also need to send the request body of the data. Lets say we want to update or change the release year of the movie with ID = 2. Using Postman or thunder client, Lets update the release year👇🏼

Lets use the PUT request method. And even though we are only updating the release year property object, we still need the entire object in the request body. But if we use the PATCH method, e don't need to send the entire object, we only send the property we want to update. 👇🏼

We want to create an API and when a request is sent to the resource we want to update a movie. Lets create the endpoint and write some logic. First we need to identify the movie object we want to update using the ID👇🏼

Lets see the response on the server, The response was successfully updated👇🏼

The object was also updated in our movies.json file as well 👇🏼

Lets update our by writing a logic to handle errors for cases where the client pass a non existing route parameter or ID👇🏼

Lets see the error response on the server when we pass in a non existing route parameter or ID👇🏼

That's all for this lesson.
