We can all agree that React Native is a great programming framework. In this article, we would like to offer some tips, tricks, and best practices to make creating with React Native even better!

Turn off logs on production

Turning off all logs (either manually or with a script) when creating a release compilation can prevent your application from slowing down. What’s more, it can also slow it down by having many console.log statements, especially if you use logging libraries like redux-logger.

Classify components

Smart containers get data from APIs, provide data to other components and perform most of the calculations. Functional components, on the other hand, provide simple functionality based on input data. What they do is receive data and display it to users. They contain all the customization. Classification into smart components and functional components allows better reuse of them and also organizes the project logically.

Flexbox

Using Flexbox is a good practice. In React Native, Flexbox works almost identically to its CSS opposite. However, note that flexDirection in React Native defaults to column instead of row. Using absolute positioning of elements instead of Flexbox in React Native code breaks the layout and prevents it from being reused.

Keep components concise

By far the best way to design components is to keep them in a way that each component corresponds to a single function. It’s a good idea to avoid having an infinitely long list of components performing multiple tasks. It’s good to have each component render only a specific section of the application page or modify only a single function. It is much easier to keep components small and short. Large components can be problematic to manage.

Track the complexity of your code

Thanks to extensions like code metrics, we can track the complexity of our code. The point is not to pre-optimize everything, because the performance of a released application can always be different from the version on your simulator. However, it’s worth being more or less aware of the computational complexity of your code because it happens that a component spends more time calculating the received data than waiting for the server to respond.

Make life easier with React Native tips

In terms of React & React Native development, for a front-end developer who is involved in creating highly functional UIs, React Native presents one of the best options. That’s why, it’s always good to be up to date with existing techniques and tricks that can make your life with RN in 2022 even easier!
