What are the best practices for Reactjs?
If you are looking to make the most out of your React powered creations, you are most likely to follow Reactjs best practices. Doing so will help you to keep your code organized throughout your app development. In this article, we will list the best practices to follow while working with your React-based application.
- Keep Components small and function-specific: As we know that React follows Component-based structure i.e., it allows the developers to break the complex UI into small pieces called components. However, it is possible to have huge components that can execute a no. of tasks at a time but it is advisable to keep them small and specific to one task only. Function-specific components make testing and maintenance easier. If components are small, they can be reused across multiple projects and can be updated easily.
It’s good to create as many function-specific components as you want and to recombine them in a way to achieve the desired goal.
- Lazy loading for saving Bandwidth and time: Lazy Loading allows you to load components lazily through code splitting without the help from any external libraries. Lazy loading is a technique of rendering only needed items first, then quietly wrapping up non-critical items later. Lazy loading in react is carried out by using React.lazy() function.
Sometimes getting lazy can be productive, so get lazy with react and saves bandwidth and loading time by delivering the content whenever a user needs it.
- Don’t Repeat Yourself (DRY): One way to keep your code healthy is to avoid duplication. It is good to make a habit of not repeating yourself to keep your code as brief and concise as possible. You can achieve this by examining the code for patterns and similarities. If you find any, it’s a possibility that you are repeating code and there is a need to eliminate duplication.
- PropTypes: It is good to keep propTypes as minimal as possible and all the propTypes used should always be defined. Very long or very short prop names are bad news. It’s a good idea to define propTypes in an easily recognizable way making it useful for any developer working on the same project.
- Naming in the End: Name a component after the function that it executes so that it should be easily identifiable. Naming a component corresponding to its function increases its reusability.
- Comment only where required: Attach comments to code only where required. More comments against code make it visually untidy which in turn becomes tough for a developer to distinguish between comments and code.
Conclusion
I hope the above list of React best practices will put your project on the right track and will help in avoiding any potential problem later in the development.
