API design refers to the process of developing application programming interfaces (APIs) that expose data and application functionality for use by developers and users. APIs are important to modern organizations, adding new capabilities to everything from their operations and products to their partnership strategies. It’s no longer a stretch to say that most organizations don’t ask whether to engage in API programs, but how to do so. Hand holding your end consumer to success whenever they hit a road block working with your API will go a long way in improving developer experience and preventing API misuse. Describe these error responses well, but keep them concise and neat. Provide enough information in the error codes for an end user to start work on fixing the cause, and, if you feel there’s more information needed, provide links to additional documentation.

Cache data to improve performance
Much as documentation is built and rebuilt as you update your API description, mock servers can also automatically have your latest changes. Integrate with your own API as you build it by including mock server endpoints in your code, or coordinate with API consumers and collaborators to write tests or sample code. Code you write against a mock server isn’t wasted, because only the server root will change when you move to production. These standards and informal working agreements look a lot like the beginnings of an API.
Step 2: Define the API contract with a specification
See the source code of this example application to understand it better. So our resource URIs and their representation are fixed now. Let’s decide all the applications’ possible operations and map those operations to the resource URIs. This sub-collection of configurations will be a subset of the primary collection of configurations and will be specific to a device only. In the next chapter, we explore ways to make the client react to changes on the server in real time. Business is so good, in fact, we decide we want to start tracking orders by customer to gauge loyalty.

The documentation helps make developers' lives a lot easier, too. If you've got resources that should only be available to authenticated users, you should protect them with an authentication check. We've spoken about best practices to increase the usability and performance of our API. You can build the best API, but when it is a vulnerable piece of software running on a server it becomes useless and dangerous.
6. Single Configuration Resource under a Single Device
This can be handled inside another middleware we use for the routes we'd like to protect. For example our POST request to /api/v1/workouts for creating a new workout. We can define a new cache by calling apicache.middleware and use it as a middleware inside our get route. You just have to put it as a parameter between the actual path and our workout controller.
Adopt RESTful API Principles and Use HTTP Methods Wisely
For example all workouts that have the mode "For Time". Imagine we've got 2,000 workouts, 450 records, and 500 members stored in our DB. When calling our endpoint to get all workouts we don't want to send all 2,000 workouts at once. This will be a very slow response of course, or it'll bring our systems down (maybe with 200,000 😁). Every error that gets thrown inside our Workout.createNewWorkout() method will be caught inside our catch block. We're just throwing it back, so we can adjust our responses later inside our controller.
Determine Resource Representations
We can’t manipulate this data as easily on the client-side, especially in browsers. It ends up being a lot of extra work just to do normal data transfer. Mocking API calls before they’re in production is a good idea.

Many server-side app frameworks set the response header automatically. Some HTTP clients look at the Content-Type response header and parse the data according to that format. A REST API is an application programming interface architecture style that conforms to specific architectural constraints, like stateless communication and cacheable data.

But as I've written in the introduction this isn't always very wise and should be considered by the engineer themself. That's the reason why it's always a good practice to return proper HTTP error codes for different cases. This helps the consumer or the engineer who built the API to identify the problem more easily. If you try to add the same workout for a second time, you still receive a 201 status code, but without the newly inserted workout. Now you can go to your HTTP client, send the POST request again, and you should receive the newly created workout as JSON.
Use the same presentation fields as the primary collection. Opposite to collection URI, a single resource URI includes complete information about a particular device. It also includes a list of links to sub-resources and other supported operations.
REStful APIs comprise majorly of HTTP methods which have well defined and unique actions against any resource. Here’s a list of commonly used HTTP methods that define the CRUD operations for any resource or collection in a RESTful API. Reading documentation is one way to determine how an API works. Live calls add another dimension to that understanding.
I think I started this in, I forgot now, '16, I think Dynamic Duo or '15 and '16, which is -- we have a custom processor for Palladium, and we use FPGA for Protium, okay? So as a result, over the years, this has become the right approach, okay? I mean NVIDIA is no longer doing just chip development.
To do that, we need a database and a collection of methods that actually handle the database interaction. Our database will be a simple JSON file that is pre-filled with some workouts already. An alternative to this practice would be to look into GraphQL. However, the problem could persist if there is a large amount of potential data to fetch.
Jump right back into our workout service and implement the logic for getAllWorkouts. Again, I've chosen to name the method inside here the same as the one in the service and the controller. Let's create our service layer by implementing the next best practice. We also don't force the clients to use the new version straight away. They can use the current version and migrate on their own when the new version is stable. The big advantage is that we can work on new features or improvements on a new version while the clients are still using the current version and are not affected by breaking changes.
So as you know, you will see more and more, not just big chips on a single node, but multiple chips in a package for this AI workload and also 3D stacking of those chips. So what this allows is not just emulating a single large chip but multiple chips, which is super critical for AI, okay? And so that will be the primary demand as more capacity chips require more hardware, okay?
A small team can work through this uncertainty without losing much productivity. But as a team grows, it needs a clearer contract between designers and developers. Establish code-free connectivity with your enterprise applications, databases, and cloud applications to integrate all your data.
