These different components remain loosely coupled and the transfer of information is fast and carried out efficiently. Since data formats aren’t defined, it serves a more diverse purpose and is easier to develop. An HTTP request is used to access and use the data with commands such as PUT, GET, DELETE, POST, etc.Ī REST API, basically defines how different applications communicate over HTTP. REST API stands for Representational State Transfer, which presents some constraints of the REST architecture style. It is an architectural style for designing networked applications (i.e., apps that use a network to communicate). Instead, they only have to provide data to the client, enabling services using different technologies to communicate in a standard way. One key advantage of an API is that developers or requesters don’t need to know the inner workings of the software. Both X and Y will be explained in the documentation for the API and specified in the contract between the two parties.ĪPIs can be used to create programs like a library (e.g., Python API), an Operating System, or a web server (a web API). If a requester sends X to a responder, the responder will give the requester Y. APIs also help create more consistency across apps for the same platform.ĪPIs are like a contract between the program’s requester (the client) and the responder (aka the server). With APIs, developers can save time by taking advantage of a platform’s implementation and reducing the amount of code.
In this article, you will gain information about Java REST Clients & API Frameworks. However, Java REST clients and frameworks are the most common and straightforward way for building RESTful applications. When it comes to building RESTful APIs, various frameworks in Java, Node.js, Python, etc., are available to streamline the application development processes across the client and server-side sub-systems. It can also be a set of configuration files and tools such as transpilers, compilers, and other programs.

Frameworks remove the complexities of managing the individual operations related to the designing of web applications and offer boilerplate code to simplify the programming logic.ĭepending on the complexity and requirements, frameworks can have a single or many libraries. For example, if they want to create a RESTful web application, Java REST clients and frameworks provide libraries and functions that make it easier to code the applications’ frontend, backend, or both. A framework offers a set of libraries, tools, and programs to support developers and creators in achieving goals like designing an application.
