7 Most Common Mistakes In React Native Development (And How To Avoid Making Them)

React Native is the best choice for app development. Developers and entrepreneurs across the globe feel great to have chosen such an alluring framework that enables fast development of the project.

React Native is getting popular

The demand for React Native is increasing day by day. The shine of bright JavaScript framework future has not gone unnoticed by the React Native developers. As this demand is expected to go only far, the React Native development companies must learn a way around the development process. Especially on the understanding front and avoid React Native app development mistakes which can ruin the user experience. There are several mentioned and unmentioned benefits of using React Native development. However, some challenges come with React Native app development. But these challenges are something that the React Native developers need to accept and workaround.

07 Common Mistakes in React Native development

1.Wrong Estimation

Layout: With the number of reusable components there come different layouts. The basic structure of an application can also be different in android and iOS.
Forms: A current estimation of the validation layout must also be made. So when you create an app in React Native, you are supposed to write more codes compared to a hybrid app.
Web Apps: Various endpoints present at the backend must also be checked. You must understand the logic in the app along with the database structure and how entities are connected, etc.

2. Wrong Redux storage

As a developer, you must focus on the data handling part as well, along with the panning of an app. Redux when planned efficiently helps in proper data management and debugging of app states. It acts as a powerful tool for managing the app data in large-scale applications.

3. Mutate state inside render function

As shown below view and data are connected. Data is a store that has all the information on the component and view, which will be rendered based on the state. It takes up the new state from the data store and shows it on the screen. However, React has a set state() function which takes up a new object state and compares it to the previous state. Add the new state to the merged previous state and send it across the data store. This cycle will be there throughout the component lifetime.
When you mutate the state directly, then the life cycle will be messed up and it can corrupt all the previous states. The application can behave abnormally or crash sometimes. And when this happens, you will lose the track of all states and might end up writing custom code instead of React. Thus, these problems can occur if you mutate the state directly. So avoiding this mess up, you can create a child component for content that is inside the function and pass it down as a prop.

4. Misuse of Redux

If your application is large, then managing and debugging app states is easy with Redux. But do not use Reduxtime-consuming.

5. Left “console.log”

The console log statements are handy and even help with debugging the app. But this can be a serious problem if you leave log statements in the app itself. If you keep rendering logics inside, those which are asynchronous can lead to a bottleneck in the JavaScript thread. All this can ultimately lead to the application becoming slower.

6. Stateless components

Some developers think that React 16 holds even now. However, the stateless components mean that they do not extend any class as it takes up the argument as display and props in DOM. It comes with features like:
Easy testing ability, Fast implementation, and no use of local variables. Now, with the changing time, it has become crucial to use pure components for the developers.

7. Not optimizing Native images

As a developer, you must not ignore optimizing the images in the apps built using React Native. Optimizing helps in resizing the images locally and then uploading them to cloud storage like a s3 server and then getting the CDN link that can be returned using API. The image loading process can be faster using this process.

While these are only 7, there can be more issues as well, but as a developer, your ultimate goal should be to make as few mistakes as possible.
