An event-driven programming to servers which helps in making the servers work really fast in javascript is node.js. Node.js an event driven programming based is a simplified model created as there were many difficulties reported in server side programming. Node.js uses different modules that are responsible for various core functionality. It runs on various Operating Systems such as MacOS, Linux, and Windows. There are API designs mainly used to make the performance of server side applications better.
API in Node.js
Rest is web standards-based architecture which uses HTTP protocol for carrying out different various functions. Rest client accesses and modified the information using the protocol but for that Rest server simply provides the access. To represent the resource it takes help of different sources such as text, JSON, XML but JSON is the most popular one. The API creates a huge impact on the program’s usability. There are different HTTP methods used to in REST based architecture. API is typically defined as the set of HTTP request messages.
Restful APIs:
GET: It displays the list of all the users. Read-only access to a resource.PUT: Adds resources to the list. It helps tp create a new resource.DELETE: Removes a resource.POST: Update an existing resource. It also helps to create a new resource.According to the client’s request, there will be changes made in the database using those API’s. This Hyper Text Transfer Protocol request message will reduce the complexity. Different functions of adding, deleting, or updating a resource from the list can be carried out with easily.
These were some HTTP methods used by the Restful API in node.js. It creates uniformity in the code and makes it easy to understand and execute as well. Hence node.js provides a rich library of various modules which gives a subject wider scope. The reliability increases and thus error finding and fixing can also be improved.
