Nowadays, with the increased popularity of Single Page Application (SPA), developing a Front-end application requires more tools, more frameworks and also more attention from software engineers to application architecture so as to make sure high performance and scalability. When the complexity of your SPA increases, more people have to work on the application at the same time and a larger number of components and UI elements are built. That results in the application scalability becoming a signification problem. Without a good approach, the more complicated our application becomes, the buggier, the more unproductive and low-performing it becomes. React and Redux are one of many technical stacks which provides a lot of support to developers to build a solid SPA in an easy and effective way. They are easy to pick up and to be productive with. This presention will discuss benefits of using React and Redux as well as how to architect application in order to scale effectively without sacrificing benefits we have from React and Redux.
