Which is the most challenging part of an app development project? Developers must assure that the mobile app would work everywhere smoothly. To solve this problem, React Native has made its entry to the app development world. A cross-platform development framework, i.e., React Native, has achieved success within a short time. Of course, it has drawn the attention of developers struggling to build an app that runs smoothly on every platform. Lots of app development companies have started designing their React Native apps as the best cross-platform development solutions.
Moreover, code reusability of the React Native framework has simplified the programming process. With some knowledge of web development and official documentation, developers can create the cross-platform app. These advantages have also curtailed the app development cost. However, without the relevant information about this framework, you have a chance to make mistakes.
Thus, in this article, we will discuss the common mistakes one must avoid while developing the React Native app.
No optimization of images of the React Native apps-
Some React Native developers do not focus on the need to optimize images. Ultimately, they find an adverse effect on their app performance. To prevent degrading performance of your app, it is essential to keep images optimized.
Besides, this optimization process also affects your app size, and you can find a lightweight app with this trick. A reliable React Native app development company does not avoid image optimization steps for a better quality app. Also, your app will not consume much storage space and high memory.
What are the ways of loading images fast?
- Use smaller images
- Cache these images to load them fast
- Instead of JPG format, you can choose PNG
Improper management of Redux store for React Native apps-
Lots of developers like to deal with innovative app development solutions. However, instead of focusing on data, they put a higher priority on the app layout.
Redux plays an important role in the proper storage and management of data. It also helps the React Native developer to debug app states.
Not to mention, Redux is a reliable tool to control app data in a way that you desire. However, when you cannot use Redux, there will be a full mess-up.
Another notable factor is that it is not the right choice for small app development projects. Although it is a minor change, you may need to write long codes. Thus, React Native can be the perfect option only for large-scale applications.
We have some tips for use Redux for your React Native mobile apps with the right configuration and file structure.
- Organize and define files while developing a store hierarchy
- Add the first reducer option- You may also need diverse states due to the apps’ difference.
- By adding several reducers, you can combine them.
- Decide on the need of using middleware
- The last step is to adjust the Redux store
Lots of programmers choose Redux, and they do not think of their viability.
No use of the right coding practices
A wrong coding practice could result in a serious issue to your app. You are familiar with the basics of coding. However, do you know something applicable only to React Native applications? Let us now see what problem you can encounter without the best coding practices.
- You cannot scale up the app anytime- At times, you may think of altering the code based on your needs and purposes. To do it, you are bound to write several code lines. Therefore, you must apply the proper coding practice to deal with the app development process.
- You will face readability issues- For higher code readability, you need to define types of prop and separate render elements into some easily interpretablehelper function().
Overlooked console.log statement
Some React Native app developers do not give high priority to console.log statement. However, this statement simplifies the task of detecting bugs from the app very easily.
Moreover, console.log statement is the best option to identify issues in the code lines and find app performance problems. Sometimes, you cannot make out why your app is not performing rightly. To detect hitches in your efforts, you may rely on the console.log statement. Also, use this statement to ensure better app quality.
Mistakes in estimation
Lots of novice React Native developers make this mistake while developing the app. They must have different layout estimation for iOS and Android versions. Furthermore, they have to think of the reusable components for these apps. The app page structure has to be entirely different for iOS and Android mobiles.
While estimating forms, developers have to deal with the validation layout. Besides, they need to check endpoints offered by the backend at the time of designing the web app.
Proper coding is essential to manage the app logic. Ensure that you know the database structure and connection of entities. It helps you in organizing your Redux store.
No unit test
Some developers are not much attentive while creating their apps. Surely, you may find several apps performing smoothly without undergoing the unit test. However, it is not the right approach.
Although the unit test is not an obligation, it is necessary to make sure that your app segments are working independently. You have to check out the app functionalities with this unit.
Besides, we think it to be a major mistake in developing React Native applications. You have to do a unit test for every component and track the potential bugs.
No analysis of the outer module codes
Some React Native mobile app developers add outer modules to the app development project. However, they make the mistake of avoiding the outside module codes. These outer modules may have some issues. They do not work in the way we desire. Thus, a proper analysis is vital for smooth app performance.
Using stateless components to have better performance
Some programmers rely on stateless components to find reliable app performance. However, what are these components? Stateless components have no local state, and they come up in the DOM. The common features of stateless components are-
- Developers can implement them fast
- They can test those components easily
- These statements do not use local and state variables
Instead of these stateless components, it is better to use PureComponent. Lots of programmers choose PureComponent for the implementation of class-based React Native mobile app components. Also, there is no need to re-render these components unnecessarily for several times. Thus, you can find the best performance and speed in your app.
To sum up, you have to keep away from these mistakes when you develop a React Native mobile app. When you are creating an app for the first time, it is better to avoid React Native. The best choice is to hire professional developers from a Mobile app development agency. A minor mistake can delay the overall development. Thus, save time and money with the right steps during the mobile app development.
