With about a little over 1,600 regular active contributors all working together in order to make React Native the success that it is now, the glitter of a much brighter framework has reportedly gone unnoticed by a number of developers that are trying to make a name within the world of cross-platform. The overall demand that React Native is now getting from different developers is not just due to the fact that the industry has massively grown up to an extent where it is now being compared to both Native and React Native modes of development. The overall demand is also reportedly driven by constant updates that reportedly make the framework more advanced.

This demand, however, can only go as far as it can. Ultimately, on the ground level, developers will still have to learn their ways in order to navigate around the whole development process. This is true especially on the front end of being able to understand and also avoid certain React Native app development mistakes through the use of certain React Native testing tools that can help avoid ruining the users’ experience as well as their skills.

Why is React Native popular?

1. React Native uses JavaScript

JavaScript is known to be one of the programming languages which a developer usually starts off with. This would mean that developers would naturally have a detailed resemblance of the subject matter. The main fact that React Native actually relies on JavaScript actually brings down the learning curve to a great extent.

2. Build native applications

Even though most developers work on JavaScript, they still reportedly don’t use the web view for rendering the needed React Native components. One main reason why developers should choose React Native is due to it being able to render real negative elements and also gives developers the flexibility for them to use certain platform specific components as some activity indicators. This gives the platform somewhat of a very recognizable, native-like feeling.

3. Installation process is very straightforward

Direct installation process. The whole installation process should always be direct, of course, minus any of the complicated steps. The whole React Native framework can reportedly be installed through the use of the Node Package Manager, which makes things extremely easy for the developer that already has a JavaScript background for them to follow. Even with the developer’s lack of understanding of JavaScript, React Native will reportedly prevent the developer from the whole hassle of having to download binary coming from the source.

React Native testing tools. There are, however, a few common mistakes that some React Native app developers make. The use of React Native testing tools is also very important in order to spot these mistakes and correct them. However, the developer should really pay close attention and avoid making these mistakes otherwise.

Common React Native mistakes

1. Wrong estimation

Estimation mistakes. Coming up with wrong estimations can be a fatal mistake. Although the platform has a layout for the Android and iOS version, there will still be quite a number of other reusable components. However, there could still be a number of different layouts as well. In fact, the mere structure of a particular application page can also be different on both the Android and the iOS completely. 

It is very important to estimate the validation layout as well when the developer is creating an app in React Native. Users are urged to write more codes in comparison to when they are creating a Hybrid app on let’s say the supposed Cordova.

Check different endpoints. When creating a web app, it is important for the developer to check out the different endpoints which are reportedly offered by the basic backend. Due to the developer having to handle the basic logic within the app, it is important that everything should be coded correctly. Developers should also be able to understand the whole database structure, how certain entities are connected, and more.

2. Wrong planning redux store

As a developer, when getting a particularly innovative project, the developer focuses more on planning out the app layout and also less on the part that handles data. Redux will help store the data correctly when it comes to managing and debugging app states. When things are planned right, this can be quite a powerful tool for developers to manage the app data, when not, this could go wrong and really mess a lot of things up.

Another important note is that the Redux app development is not really suited for small projects. Although small changes could still ask developers to write really long lines of code, it would still be better if the developer would choose this for large scale applications and also avoid it whenever choosing React Native for certain startups.

3. Failing to read external modules’ codes

Although it’s not uncommon for developers to steer clear of external modules, it could still make things much easier and faster especially since they also come with documentation. Most, but not all, of the modules break or they might not really work as originally anticipated.

This is particularly the reason why developers should still read the code and also treat the step as, well, one of the basic React Native practices. Doing this would help the developer find out what is wrong with the module and what can be done to solve it.

4. Left “console.log” statements

Console log statements have proven to be extremely helpful. However, what would happen when the developer leaves the log statements within the app itself? This can be a serious issue later on especially if the render methods and the logics are left inside. Ultimately, the application will become slower.

5. Not being able to optimize React Native images

This should be a top priority for React Native developers. Locally resizing the images then uploading them to the online cloud storage like the known s3 server then proceed to get the cdn link which can then be returned using the API.
