Angular best practices

Building scalable software is a challenging task. When we think about scalability in front-end applications, we can think of increasing complexity, more and more business rules, a growing amount of data loaded into the application and large teams often distributed around the world. In order to deal with mentioned factors to maintain a high quality of delivery and prevent technical debt, robust and well-grounded architecture is necessary. Angular itself is a quite opinionated framework, forcing developers to do things the proper way, yet there are a lot of places where things can go wrong. In this article, I will present high-level recommendations of well-designed Angular application architecture based on best practices and battle-proven patterns. Our ultimate goal in this article is to learn how to design Angular application in order to maintain sustainable development speed and ease of adding new features in the long run. To achieve these goals, we will apply:

• proper abstractions between application layers,

• unidirectional data flow,

• reactive state management,

• modular design,

• smart and dumb components pattern
