Top 7 Common Mistakes to Avoid When Developing React Native Apps

The best choice for cross-platform app development is React Native. The React Native framework makes it possible for developers to create projects quickly for business owners and IT professionals around the globe. React Native is developed by Facebook, is an open-source cross-platform framework.

Being a renowned React Native app development company, we have immense expertise in cross-platform app development. We have ample experience in customized feature-rich mobile application development that is compatible with multi-platforms.

In this blog, we have outlined the safety guidelines for developers and entrepreneurs using React Native. React Native mistakes that can impede user experience should be avoided to ensure a great user experience.

Developing React Native Apps: 7 mistakes to avoid

1. Choosing the wrong redux store layout

Developers tend to focus more on planning the design of the application rather than the processing of data when working on an innovative project.

With Redux, you can store data correctly and manage and debug app states. When planned properly, it can serve as a valuable tool for managing app data. If not, it can cause many problems.

Additionally, it should be noted that Redux is not highly suited for small projects when it comes to application development. This is because you will be required to write a significant amount of code, even for small changes. Therefore, it is better to choose React Native for large-scale applications and avoid it for small-scale applications.

2. Modifying state within a render function

Data contains all of the information regarding a component that will be displayed on the state. The program collects and displays data from the store. Using the set state() function in React, you can take the new object state and compare it to the previous one. Once this has been done, a new state will be added to the initial state, and data will be sent around. 

This cycle would run in a vicious circle. A direct mutation would cause the life cycle to be tangled, and the previous states could be corrupted.

Appliances can sometimes display abnormal behaviour or crash. This leaves you with no idea of your state and creating custom code instead of React. If you directly modify the state, you can get these fixes. Thus, to avoid ruin, you will create a child component and pass down the prop of the content inside the function.

3. Ignoring external modules’ codes

External modules often save developers a lot of time. In addition, the documentation makes things easier and faster.

Even so, it is more likely that modules will break or they will not work. As such, developers should take this step seriously as a React Native best practice. This enables us to determine why a module isn’t working and how to fix it.

4. An incorrect estimate

Application layout:

The layout of the application varies from the Android version to the iOS version.

Forms:

It is suggested to make an estimation of the validation layout based on the information provided currently. Compared to a hybrid app, you will have to write more codes when using the React Native framework.

Web Application:

There should be a review of several backend endpoints. A clear logic should be apparent in the app with regards to the database structure and how entities are connected.

5. Components that lack state

Stateless components, however, mean they do not extend classes since they use arguments as display and props in the DOM. Features include:

• No use of local variables 
• Simple testing 
• Fast implementation.

With the passage of time, the development community is increasingly focusing on pure components. Here are the reasons –

Performs shallow comparison –

UI applications with complex UIs will benefit from this since rendering operations will be reduced. It uses a life cycle method called shouldComponentUpdate, which performs automatic comparisons followed by a check to see if a re-render is required. Whenever the parent component re-renders a stateless component, the component will re-render. Pure components, however, are re-rendered only if the state or props change.

Performs side effects –

Within componentDidmount, developers can generate AJAX requests or conduct other DOM operations.

6. Statements left in “console.log.”

Logging statements in the console are beneficial. You can even debug the app’s execution with their assistance. What happens, however, if you leave the log statements in the app?

If your render methods and logic are kept inside, primarily those asynchronous, the JavaScript thread can be bottlenecked, which is a severe problem. Combined, all of these factors slow down an application.

7. Leaving native images unoptimized

The picture optimization within React Native apps is not something you want to ignore as a developer. Optimization permits resizing localized images then uploads them to a cloud storage server like S3 to get a CDN URL that will be returned via API. This method can speed up the loading process of images.
