So anything needs to be done on the request and response object will have to be done in the controller only. Service Requestor Service requestor is the application that is looking for and invoking or initiating an interaction with a service. The RESTful service, Customer Service, will be developed in Node.js with Express.js. Advantages of RESTful Web Services. The bottom-up view of Web services architecture defines the message exchange patterns and extended functionality by placing the fundamental aspects of Web services into relationship: the message, sender, receiver, intermediary, and extended functionality data or context. It will make the API less confusing to the consumers. When Facebook guys started looking for a different way of fetching data from the server, they were trying to resolve the problem of under-fetching or over-fetching that the existing API protocols had. REST is an architectural style not a protocol. It is one of the options for Amazon Web Services. The following figure illustrates using REST for Web Services. Without clearly defining the architecture of the system we cannot build it without any issue. Building web services using the RESTful approach is emerging as a popular alternative to using SOAP-based technologies for deploying services on the internet, due to its lightweight nature and the ability to transmit data directly over HTTP.
