When using this option, you can set specific directives such as max-age, must-revalidate or no-transform.

Yes, especially in enterprise environments for their security, extensibility, and standardized protocol.
Architecture
For example, your cookbook API may need to return only recipes from a specific category, or you want to show the recipes with the least prep time. Rather than create redundant endpoints, plan for smart parameters from the start. In addition to the API architecture and recommendations outlined in Roy Fielding’s dissertation, we now have two decades of practical application. When designing API projects, it makes sense to build upon the REST best practices and guidelines for web services already implemented by countless others.

The API design process benefits both consumers and producers by ensuring that APIs support business objectives while remaining easy to use, adaptable, testable, and well-documented. API design should occur early in the API lifecycle in order to achieve alignment among key stakeholders and to help teams identify issues before they become ingrained. API design is also an important part of an effective API governance strategy, as it helps teams standardize API patterns that can be reused across their organization.
API Gateway Patterns in Microservices
We filter all the records that are related to the workout id out of the query parameter. Chances are high that have we to implement CRUD endpoints for the records as well, because records should be added, updated or deleted in the future as well. I always imagine that the HTTP verb describes the action (what we'd like to do) and the URL itself (that points towards a resource) the target.
A long and difficult-to-read base URL is not just bad to look at, but can also be prone to mistakes when trying to recode it. There’s no rule on keeping the resource nouns singular or plural, though it is advisable to keep collections plural. Having the same plurality across all resources and collections respectively for consistency is good practice.

It’s important to thoroughly understand how an API will be used and get feedback from collaborators, such as with mock API servers. As you design your API, you’ll want to rely on these methods to express the primary purpose of a call rather than adding the purpose to the RESTful API URL. Versioning is important in API design because it allows you to make changes to your API without breaking existing clients.
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. In our example we're not using a real database such as MongoDB or PostgreSQL because I'd like to focus more on the best practices itself.
It should provide examples and code snippets to help developers get started quickly. Additionally, documentation should be kept up-to-date with any changes to the API, to ensure that developers always have the most accurate information. Understanding API design patterns is crucial for creating high-quality APIs that meet the needs of both developers and end-users. By following best practices and leveraging established patterns, developers can create APIs that are intuitive, reliable, and user-friendly, improving the overall experience for all stakeholders.
Essential Patterns for REST API Endpoints
By versioning an API, clients can continue to use an older version of the API while newer versions are developed. This allows clients to gradually migrate to the new version of the API without breaking existing functionality. Message Queue APIs facilitate asynchronous communication and processing through message queues. Event-driven APIs are based on responding to events or changes rather than traditional request-response models. 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.
As you can see, we've added the two properties "memberId" and "member" to our records inside the database. This has the huge advantage that we don't have to nest deeper our existing endpoint. The endpoint now becomes less manageable the more nesting we add to it. Therefore it's a good practice to store the URI to receive information about a member directly into the record. Now we're able to create a new route in our workout router and direct the request to our record service.
The above suggestions are just that — advice and recommendations which can be used or discarded depending on your user case and requirement. One of the main reasons why API design is crucial is to help the end consumer use your API. Their needs should be the guiding light towards designing and building a great API. Notice the data types and an example described in each response item an end user can expect from a successful GET call. The successful response an end user would receive in JSON would look as follows. The issue is whether you should wrap the data (especially collections) with another key in your response.
We're using "$ref" to create a reference and are referencing the path to our schema we've defined inside our workout file. Typically this definition will be inside your schema or model file where you've defined your database models. When you take a close look at our response, you'll see that we haven't defined the correct return value because we're just saying that our "data" property will be an array of empty objects. Always remember that the documentation is usually the first interaction consumers have with your API. The faster users can understand the documentation, the faster they can use the API. I think there's a lot truth in this statement because if an API is not well documented it can't be used properly and therefore becomes useless.
