What is Rest API

 


API is short for Application Programming Interface (API), which describes a class library's characteristics or how to use it. Your personal library may contain "API documentation" of available functionality.


A REST API in API Gateway is a collection of resources and methods integrated with back-end HTTP endpoints, Lambda functions, or other AWS services. You can use API Gateway features to help you with all aspects of the API lifecycle, from creation through monitoring your production APIs.


API Gateway REST APIs use a request/response model where a client sends a request to a service and responds back synchronously. This kind of model is suitable for many different kinds of applications that depend on synchronous communication.


When many people refer to API documentation these days, they often refer to an HTTP API that might share your application data over the web. For example, Twitter provides an API that allows users to request tweets in a specific format to easily import them into their own applications. This is where the HTTP API is potent. It can mix and match data from multiple applications to a mixed application or create an application that enhances the experience of using other people's applications.


It is an application that allows us to view, create, edit, and delete parts.


REST is the shorthand for Representational State Transfer, which was proposed by Roy Fielding T to describe the standard way of creating an HTTP API, and he found that the four common behaviors (view, create, edit, and delete) could all be mapped directly to the implementations in HTTP.


The different HTTP methods:

• GET

• POST

• PUT

• DELETE

• OPTIONS

• HEAD

• TRACE

• CONNECT


Most of the time, when you're looking at your browser's dots, you're using the HTTP GET method. The GET method is only used when you request resources from the Internet. When you submit a form, you often use the POST method to send data back to the site. As for the other approaches, some browsers may not fully implement them at all. But that's fine if it's for our use. We have many HTTP methods to choose from to help describe these four behaviors, and we will use client libraries that already know how to use these different HTTP methods.


Rest API benefits:

• Resource oriented, easy to see

• To GET something, you need to GET (GET is safe, does not modify the service resource), you need to POST (POST is unsafe), you need to PUT (PUT is idempotent), and DELETE (DELETE is idempotent).

• Traditional CRUD requires four different interfaces, but the REST API requires only one. (Distinguish between different requests)

What is software architecture design?

I. Concept of system architecture By Edward Crawley, Bruce Cameron, And Daniel Selva co-authored SYSTEM ARCHITECTURE: Strategy and Product Development for Complex Systems. In the book, the word "system" is defined in this way: a system is a set of entities and their relationships, whose functions are greater than the sum of their respective functions. In other words, the function has to be 1+1>2, which is called emergence. For example, a pile of bricks and wood cannot provide shelter from the wind and rain, but they can form a warm house. The function of the house is greater than the sum of the functions of the pile of materials, so the house is a system. Now that you know what a system is, let's look at what a system architecture does: 1) Determine the form and function of the system. To put it bluntly, it's analyzing requirements. 2) Determine the entities, forms, and functions of the entities in the system. It's dividing up the system. To accomplish this tas

differences and benefits between JUnit 4 to JUnit 5:

https://www.baeldung.com/junit-5-migration According to this blog what I study for the Junit 4 and Junit5: JUnit 5 is a powerful and flexible update to the JUnit framework, providing various improvements and new capabilities to organize and describe test cases and to help understand test results. Upgrade to JUnit 5 is quick and easy: Just update your project dependencies and start using the new functionality. JUnit 4 bundles everything into a single JAR file. JUnit 5 consists of three sub-projects, namely JUnit Platform, JUnit Jupiter, and JUnit Vintage. 1. JUnit platform It defines TestEngine's API for developing new testing frameworks that run on the platform. 2.JUnit Jupiter It has all the new JUnit annotations and TestEngine implementations to run tests written with those annotations. 3.JUnit Vintage Support for running tests written by JUnit 3 and JUnit 4 on the JUnit 5 platform. But here are four strong reasons to start writing new test cases with JUnit 5: JUnit 5 takes advan
