Короткий опис(реферат):
In the modern world, most applications are built using software as a service (SaaS), client-server approach. With server-rendering is no longer being a common nor recommended practice for most scenarios, Frontend development became separated from the Backend one. They might be built using different languages and technologies and will usually be hosted on two different servers, one for web’s static files serving and another for the application programming interface (also known as API) server. The only thing that ties those two is the HTTP protocol. With that, the whole application development becomes more flexible as frontend and backend teams can work independently of each other and even test their code using mock data (for frontend) and an API development tools like Postman (for backend) to be completely separate.
