Having verbs in our API endpoint paths isn’t useful and it makes it unnecessarily long since it doesn’t convey any new information. 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. We've defined some basic metadata of our API, created the docs in JSON format, and created a function that makes our docs available. Because we've planned to have different versions of our API, the docs will be a bit different, too. That's the reason why I'd like to define our swagger file to spin up our documentation inside the corresponding version folder. In Express, for example, you can implement it as a middleware like we did with our cache for specific routes and check first if the request is authenticated before it accesses a resource.

Accept and respond with data in JSON format
Systems that implement REST APIs can scale efficiently because REST optimizes client-server interactions. Statelessness removes server load because the server does not have to retain past client request information. Well-managed caching partially or completely eliminates some client-server interactions. All these features support scalability without causing communication bottlenecks that reduce performance. In REST architectural style, servers can temporarily extend or customize client functionality by transferring software programming code to the client. For example, when you fill a registration form on any website, your browser immediately highlights any mistakes you make, such as incorrect phone numbers.

RESTful APIs have various methods to indicate the type of operation we are going to perform with this API. Radix UI is quickly rising in popularity and has become an excellent go-to solution for building modern design systems and websites. It is recommended to use fewer nesting levels to prevent overcomplicating your application; you can use filtering to reduce the number of nesting levels. Two-level nesting typically keeps the API simpler and gets the job done.
Apply consistent formatting
This makes it easy to visualize associations, aggregation and composition. A similar thought process is helpful in identifying RestAPI Models. When the stake holder is a real person it is a user persona and when it is another system it is a system persona. It is suggested that you have those understanding before attempting design. A good API makes is easy to develop a program by providing all the building blocks intuitively and efficienty. Here is the complete diagram to easily understand REST API’s principles, methods, and best practices.
Retrieving data from the database is usually required in bulk instead of from a single object because most operations are plural and list-based. Therefore, we should use plurals for the endpoints in our API. This keeps things simple and consistent between our API and the databases. However, when we want to refer to verbs, we mostly refer to HTTP methods such as GET, POST, PUT, and DELETE.
The script makes sure that the development server restarts automatically when we make changes (thanks to nodemon). We won't overcomplicate things, and we'll build a simple but organized project structure. 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.
Swagger UI is a popular API visualization example that makes the in/out data structure of an API visible; it also exhibits simulated responses to given API caller requests. Some users can create their own account within a particular application, but do not have permission to delete it. Other users might have read permission, but not permission to update, create or delete a resource.
The code
The update operation is an idempotent operation, and HTTP PUT is also an idempotent method. The only difference is that configurations for a device are only two, so only two configuration items are listed as subresources under the device.

Simply put, a REST API is a medium for two computers to communicate over HTTP (Hypertext Transfer Protocol), in the same way clients and servers communicate. It is a software architectural style created by Roy Fielding in 2000 to guide the design of architecture for the web. These decisions should be captured in an API definition, which is a human- and machine-readable representation of an API's intended functionality.
I know that documentation is definitely not a favorite task of developers, but it's a necessary thing to do. 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.
This format can be different from the internal representation of the resource on the server application. For example, the server can store data as text but send it in an HTML representation format. The code above uses Response, an object in Python that records and stores a server's response to an HTTP request. Express.js is another REST API framework for Node.js that enables developers to create a response object and program custom responses to GET, PUT, DELETE. Then, they can simply call a specific port number using the .listen command.
