We already caught the case that the request body is not built up properly and got missing keys that we expect. 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. In a perfect world everything works smoothly without any errors.

While this post does its best to cover overall API design patterns, you’ll want to look at standards and conventions specific to your industry or a specific feature. Very few of us are building completely unique APIs, so there is a lot to learn from others. In essence, understanding and applying these API design patterns and their secrets is key to developing APIs that are not only functional but are also robust, scalable, and a delight to integrate with. As you employ these patterns in your projects, remember that the ultimate goal is to create APIs that are efficient, user-friendly, and adaptable to future needs.
Benefits of using API Gateway in Microservices
When you take a look at options.apis in our swagger.js file, you will see that we've included the path to our workout routes and to the workout file inside our database folder. This is the most important thing in the setup that will make the whole magic happen. Inside Postman or another HTTP client of your choice, define a new request that gets all workouts. I've done it inside the browser until now, but I'd like to visualize the response times better for you. That's the reason why I'm requesting the resource via Postman right now.

With streaming, the server incrementally handles the large datasynchronously, such as Cloud Spanner API. With media, the large data flowsthrough a large storage system, such as Google Cloud Storage, and the servercan handle the data asynchronously, such as Google Drive API. Any information that the client needs to send prior to the half-close mustbe defined as part of the request message. You can find out more about defining methods, requests, and responses inthe Standard Methods chapter of this DesignGuide. If a duplicate request is detected, the server should return the responsefor the previously successful request, because the client most likely did notreceive the previous response.
Best Practices in API Design
The chosen representation structures strongly influence the design time and runtime qualities of an API. The evolution of API specifications and their implementations has to be governed. Rate limiting improves API performance by preventing abuse and denial-of-service attacks through setting constraints on the number of requests a user can make in a specific timeframe. To protect web services and ensure access to sensitive data for only authorized clients, API authentication is non-negotiable. From API keys to OAuth 2.0 and JSON Web Tokens (JWT), there are numerous authentication mechanisms that provide robust authentication and information integrity.
How to succeed as a data engineer without the burnout
For instance, some like ‘get’ and some like ‘retrieve’, so it’s just better to let the HTTP GET verb tell us what and endpoint does. 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 isn’t a single approach to API design that will work for every organization.
So you have to add another checking logic to that route and validate if the user has the privilege to access this resource. It makes a lot of sense to use a cache to serve data from, when the data is an often requested resource or/and querying that data from the database is a heavy lift and may take multiple seconds. All we do here is check if we actually have a truthy value for the key "mode" inside our "filterParams". If this is true, we filter all those workouts that have got the same "mode". If this is not true, then there is no query parameter called "mode" and we return all workouts because we don't need to filter.

Let us recapitulate what microservices actually are (and where theycame from). To address these and many other related design issues and chooseworking combinations from the many possible design options, applicationcontext and requirements must be known. Our Microservice API Patterns(MAP) cover and organize this solution space. Discover the art of crafting perfect REST API endpoints, where consistency and simplicity transform complex web development into a seamless experience. Managing deprecated API endpoints is an art that requires clear communication, providing a clear deprecation timeframe, and offering a long enough sunset period.
Accept and respond with JSON
For custom methods, they should have their own XxxResponse messages evenif they are empty, because it is very likely their functionality will grow overtime and need to return additional data.

The diagram shows the different components and design patterns that can be used in RESTful API design. The client makes HTTP requests to interact with the resources. The resources can be either collections or items, and the HTTP methods used to interact with them include GET, POST, PUT, and DELETE. API design patterns are an essential aspect of software development that allows developers to create reliable, scalable, and reusable code. With the increasing popularity of microservices and cloud computing, designing an effective API has become more critical than ever.
This article establishes context and scope of MAP, highlights service design challenges, and suggests entry points into the pattern language. Our Patterns for API Design, also known as Microservice API Patterns (MAP), capture proven solutions to problems commonly encountered when specifying, implementing and maintaining message-based APIs. Adopting specifications like OpenAPI for API design brings a host of benefits. From supporting a design-first approach to ensuring comprehensive and accurate documentation, OpenAPI takes the guesswork out of API design, and implementation. The meticulous crafting of Resource URIs in RESTful APIs, based on nouns representing resources, enhances clarity and effectiveness. But remember, while nested endpoints clarify relationships between resources, don’t nest deeper than three levels to maintain elegance and readability.
It sets constraints on the number of requests a user can make in a given timeframe, preventing API abuse and reducing the chances of denial-of-service attacks. They provide clear and concise information about any errors that might occur during the API’s operation. Uniform exception handling across the API allows for predictable error management and streamlines both API and client interactions. This should be an excellent starting point for anyone who wants to get their hands into RESTful services, with not just the basics, but essential patterns as well. The enemy of design patterns are anti-patterns, which seem sounds but are counter-productive when executed.

To make sure that when our REST API app responds with JSON that clients interpret it as such, we should set Content-Type in the response header to application/json after the request is made. 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. Back in our workout controller we receive the return value from workoutService.getAllWorkouts() and simply send it as a response to the client.
We are now passing incoming requests with "/api/v1" to our version 1 router, that will route each request to the corresponding controller method later. Inside the Controller we'll be handling all stuff that is related to HTTP. That means we're dealing with requests and responses for our endpoints. Above that layer is also a little Router from Express that passes requests to the corresponding controller. The resourcemust be accessed using the standard Get and Update methods, as wellas any custom methods that are appropriate for your use case.
This will be a very slow response of course, or it'll bring our systems down (maybe with 200,000 😁). We'll also need a record router to catch the specific requests for the records, but we don't need it right now. This could be a great chance for you to implement the CRUD operations for the records with their own routes and train a bit. 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. 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.
