Zopstore Web App Built using Three Layered Architecture

Abstract

A web application may be made rather easily, but testing, structuring, cleaning, and maintaining the code is a barrier. To address this, we use the Go language and adhere to the Three Layered Architecture. The three layers—handler, service, and datastore—are separate from one another. After receiving the request body, the handler layer parses it for any necessary information. The response is then written to the response writer after the service layer, where the program's entire logic is defined, has been called. Additionally, this layer converses with the datastore layer. It invokes the datastore layer after taking what it requires from the handler layer. All of the data is kept in the datastore layer. Any data storage device can be used. The only layer that interacts with the datastore is the use case layer. This is how we test each layer separately to make sure they don't affect one another.
