Some details of the REST APIs course
What you’ll gain from the REST APIs course:
Many of you may have come across the term REST API but how many of actually know about it? There is a very good chance that only a few of you know about it in details. If you are interested to learn about REST API in details, you are at the right place. We have the Udemy REST APIs with Flask and Python course for you. And we have listed all the details about the REST API in this review below. Let’s take a look at it.
Overview
Before we move on to any further details, it’s important for you to learn the meaning of REST and API separately. Let’s start with REST first.
To define it in simple terms, REST is the short form of Representational State Transfer. It is completely dependent on a client-server, cacheable communications protocol and stateless and is known to use the HTTP protocol. The good thing about REST is that it is easy to enter and is also a good performer at the same time.
REST is basically an architectural style which is used to develop and design network applications. Instead of making use of complex mechanisms, it uses HTTP in order to make calls between machines. REST is known to rely on HTTP for creating, updating, reading and deleting operations. If you put it all together, you get CRUD.
Now that you have a basic idea about REST, it’s time to learn about API.
API is the short form of Application Programming Interface. This is not only intuitive but it also opinionated and documented. It is considered to be one of the greatest assets of a company.
Now that you know the meaning of both the terms, it should be easier for you to understand REST API. To get a full understanding of REST API, the REST APIs with Flask and Python course is a right choice.
A REST API can be defined as a set of functions used by the developers to receive and perform responses through the HTTP protocol. For example, POST and GET.
One of the main advantages of using the REST API is that they can be applied to any programming language. This is because it makes use of HTTP. This also makes it easy to test. One of the best examples of REST protocol is the World Wide Web.
REST API is capable of providing details including request limitations, query parameters, response format, language support, HTTPS support, callback usage, etc.
The world of software engineering has been completely transformed since the time REST was developed by Roy Fielding who is known as the father of HTTP specification. REST has become an integral part of API.
Today, you won’t find single applications or projects that don’t make use of REST API. It has benefited some of the big companies to generate business including Facebook, Twitter, YouTube, and others. REST is considered to be the most efficient and logical standard when it comes to the development of APIs for web services. To learn about REST APIs, the bestseller “REST APIs with Flask and Python” is highly recommended.
In order to understand REST from the depth, you need to know about its features as well. The features that define REST include.
1. Stateless
One of the most important features of the REST API is that it has a stateless service. A REST HTTP request is known to consist of all the important information that is needed by the server to give a response. The server doesn’t memorize the request once it has been served. This is why it is called a stateless service. In this REST APIs with Flask and Python course, you can learn REST APIs from the complete beginner to expert.
2. Client-server based architecture
Client-server architecture is basically a computing model which allows the server to host, manage and deliver the services and resources required by the client. The main characteristic of this architecture is that it has more than one client computer linked to the central server over an internet connection.
3. Multiple layered systems
Another important characteristic of the REST API is that it can be served from more than one server. For example, when a request is sent by a client, response and request can be transferred to different servers in order to send back a response to the client. This is actually considered to be a good strategy as it helps to keep the internet application loosely coupled.
4. Cacheable
According to most of the developers, they assume that a technology stack is obstructing their API or application. However, that is not the case in reality. One of the most important parts of a web
application is the data. You need to cache content and send it as a response so that you can scale the web application nicely. In case, if the cache is an invalid one, you should fix the problem. This is why it is important to cache REST services so that it becomes easily scalable.
5. Implementation freedom
REST in simple terms is only used to define your online services. The main advantage of making use of REST is that it can be implemented in various ways. This allows you to develop REST services according to your wish. However, you should not forget that the caching of REST services is important for scaling.
6. Representation of resources
REST API is known to make use of URI or Uniform Resource Identifier which is important to map the data or resources. You can also take the benefit of requesting a particular data format as a response. In this case, the Internet Media Type will prompt the server about the type of the requested resource.
So these are the main features of REST API. All these together make it more useful to the developers. Having said that, to have a depth learning of REST APIs, don’t miss out on the REST APIs with Flask and Python course at Udemy. Now, let’s move on to the next section where you will get to learn about the benefits of using REST API.
The main advantages of using REST for development include the following:
1. It separates the server and the client
The REST protocol is developed in a way that it completely separates the user interface from the data storage and server. This is considered to be a big advantage when it comes to making developments. For example, it makes the interface more portable to all the other platforms. Not just that, but it also boosts the scalability of each of the projects. In addition, it also enables the components to evolve independently.
2. It is independent of the type of language and platform
The next main benefit of REST API is that it can easily adapt to the type of platforms or syntax it is used in. this as a result gives the freedom to test or change the state within the development. When you are using REST API, you can use any server including Python, PHP, Node.js or Java.
3. Visibility, scalability, and reliability
As already mentioned above, the REST API separates the server and the client. But this has a big advantage as it allows the developers to scale the product without any issue. This also allows them to check other servers and make modifications in the database. However, this is only possible when all the requests are sent correctly. To put it in simple words, by separating the two, it becomes easier to have the back and the front on separate servers. This, as a result, makes the applications more flexible and easy to work with.
Disadvantages
The main disadvantages of REST include:
Now the big question is why you should choose REST APIs. You can find the answer to your question in the REST APIs with Flask and Python course or these given pointers as followed.
It is scalable
One of the main reasons that make this protocol special from the rest is its scalable nature. This has been made possible because of the separation between server and client which allows the developers to scale the product without any trouble.
It is independent
Since both the server and the client is separated by the protocol, it allows development in the different areas of the project. Not just that, but REST API also adapts to the working platform and syntax at all times. This, as a result, gives the opportunity to different environments within the development.
It is portable and flexible
The developers are able to make changes since they are able to migrate from one server to the other whenever they want. Not just that, but it has also made it easier to have back and front on two different servers. This is considered to be a great management advantage.
After going through the details of REST API, hopefully, the concept of the same is clear to you. REST is ideal when it comes to improving performance by caching online service requests. If you want to learn more about the REST API, you can look up the internet.
