Best Practices of ReactJS

In this chapter, we will list the best practices, methods, and techniques of React that will help us maintain consistency in the application development process.

• State−It is advisable to avoid this state as much as possible. Centralizing the state and passing it as a prop to the component tree is a good practice. Whenever we have a group of components that need the same data, we should set up a container element around them to save the state. Flux pattern is a good method for handling the state of React applications.

• PropTypes−Always define PropType. This will help track all props in the application and will also be very useful for any developer working on the same project.

• Render−Most of the application logic should be moved inside the render method. We should minimize the logic in the component lifecycle methods and move that logic to the render method. The less state and props we use, the cleaner the code will be. We should always keep the state as simple as possible. If we need to calculate something from the state or props, we can do it in the render method.

• Composition−The React team suggests using the single responsibility principle. This means that a component should be responsible for only one function. If some components have multiple functions, we should refactor and create a new component for each function.

• Higher Order Components (HOC)−Previous versions of React provided mixins for handling reusable features. Since mixins are not recommended for use now, one of the solutions is to use HOC.
