As you've might noticed, there are some properties missing like "id", "createdAt" and "updatedAt". That's the job of our API to add those properties before inserting it. At the moment nothing should have changed inside our responses.
REST API design best practices and guidelines
Most representations are defined in either XML or JSON format. We will see XML examples as it is more expressive of how data is composed. This tutorial will teach us to design REST APIs for a network-based application. Please note that the takeaway from this whole exercise is learning how to apply REST principles in the application design process. My recommendation is, it is perfectly okay to use nouns are part of an URI when it is absolutely necessary. There are standard APIs such as Github APIs takes this approach selectively, such as in star a repository.

Once the models are identified and filled with attributes, identifying APIs along with its input and response becomes very easy. Any capability the resource requires could be potentially an API that needs to be exposed to the outside world. Looking to the API from each of their perspective will help the product owner com up with a complete set of user stories. This approach has the advantages of allowing the team to quickly implement APIs and also providing the flexibility to react very quickly to any unexpected API requirement changes.
What does the RESTful API client request contain?
To enforce the principle of least privilege, we need to add role checks either for a single role, or have more granular roles for each user. As the returned response since we filtered by lastName and age. XML isn’t widely supported by frameworks without transforming the data ourselves to something that can be used, and that’s usually JSON. 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. There might be best practices that are important while others might not seem to apply to your current situation.
Code on demand
All API requests for the same resource should look the same, no matter where the request comes from. The REST API should ensure that the same piece of data, such as the name or email address of a user, belongs to only one uniform resource identifier (URI). Resources shouldn’t be too large but should contain every piece of information that the client might need.
It doesn't make much sense to use verbs inside your endpoints and is, in fact, pretty useless. Generally each URL should point towards a resource (remember the box example from above). One thing that might go wrong is the database insertion Workout.createNewWorkout(). I like to wrap this thing in a try/catch block to catch the error when it occurs. For example, returning something like "The username is already signed up" should be well thought out because you're providing information about your users that you should really hide. First, we create a simple Util Function to overwrite our JSON file to persist the data.
There might be situations where you can't or shouldn't follow a certain convention. So every engineer has to decide this for themselves or with their. By following this approach, you will not need to find and remove its references from other places as well. In the case of async operation, the application shall return a task id that can be tracked for success/failure status. Subresource representation will be either same as or a subset of the primary presentation.
The code
Now we know our server is running and our endpoints are behaving as expected. Let's see some more realistic example of how our API might be consumed by a front end app. Now that our server is up and running, let's implement a simple test suit to check if each of our endpoints behaves as expected. These are the functions responsible for interacting with our data layer (database) and returning the corresponding information to our controllers. A large number of people wrongly relate resource methods to HTTP methods (i.e., GET/PUT/POST/DELETE). Roy Fielding has never mentioned any recommendation around which method to use in which condition.
How to Design a REST API
Because clients and servers work independently, we need some interface that can facilitate communication between them. A client sends a request to the server via the API, which returns the response in a standardized format like JSON or XML. Express.js is a popular web application framework for Node.js, which is used to build web applications and APIs.
In other words, let's start implementing endpoints for creating, reading, updating and deleting workouts. The new directory /src/v1/routes will store all our routes for version 1. But for now let's add a simple index.js file to test things out.

If you are planning to make changes to your API, always make sure to assign the proper version so that the client end does not break. You should provide options for clients to either continue using the previous version or try the newer one. In this article, we’ll take a deeper look at the best practices for designing REST APIs to ensure the best performance possible. I'm a fullstack dev (javascript | typescript | react | node | AWS) and computer engineering student. Here I write about the things I learn along my path to becoming the best developer I can be.
That's fine, because as I've said earlier, it's the responsibility of every engineer to pick out the best practices that can be applied to their current situation. So we can concentrate on the important thing, the documentation itself. In my opinion, the documentation of swagger/OpenAPI is very good and there are a lot of great examples out there on the internet. This schema can be referenced now in our response of our endpoint.
