Clean code to develop successful apps

Mobile apps have become an increasingly integral part of our lives in the current modern and digital world. We rely on them when making purchases online; socializing with friends and family members, and the list is endless.

Mobile app development companies have their work cut out as evident from the massive demand for apps from corporate companies, organizations, and even government. One of the most critical factors that mobile app developers need to keep in mind when developing these mobile applications is the code. It is imperative that they apply clean code processes to ensure that the final version of the app functions correctly and delivers the expected results.

WHAT IS CLEAN CODE?

This is one of the most common questions that we get from clients and mobile app developers. Simply put, clean code is a programming code that is easy to change, adapt, and understand. App developers rely on it to transform the business ideas of the clients into a fully functional mobile apps.

Mobile apps that are written as per the stipulated clean code rules and standards are user-friendly and easy to scale. Any app developer who comes across the code years down the road will be able to understand exactly what was your idea or intention when developing the application. As a result, they will be able to adjust and update the mobile app more conveniently and quickly as opposed to if the code was unclear.

Let us shift gears and look at three primary rules of creating a clean code.

METHOD EXTRACTIONS

The first question that you need to ask yourself is how long your method is. If it has too many loops or exceeds 20 lines, then you need to consider revising it. It is recommended to extract it to another method that has a name that explains its function easily.

Method extractions help to read the code structure easily. Usually, it is easier and less stressful to read a method that comprises of 20 lines calling five different methods than a method that contains 300 lines that are not logically named and have twisted commentary.

LESS CODE WORKS BETTER FOR YOUR APP

During the initial stages of creating mobile applications, most app development companies end up writing more code than needed. There may be too many variables which do not add any significant value to the applications as well as blocks of logic and “if” statements. All these unnecessary additions can be extracted to a separate method. It is also important to note it is not mandatory to assign a result to every variable that you create unless the functioning of the app is dependent on it.

The bottom line is that mobile app development companies should strive to reduce the amount of code in one place by expunging unused or unnecessary variables. The goal should be to create a code that is self-explanatory, so, as the app developer removes the variables, does not forget to remove the comments as well.

PRACTICE GOOD NAMING

Give colleagues or any mobile app developer who may be hired to improve the application down the road an easy time by properly naming the class, method, and all variables that you create. One of the guaranteed ways of achieving this goal is by avoiding using abbreviations on the app code.

For instance, an app developer would have to check the method body to know the meaning of “userAction”. The names should be self-explanatory.

AVOIDING TECHNICAL DEBT

Unknown to most mobile app developers is that creating confusing or sloppy codes automatically introduces technical debt to the project. Well, technical debt can positively influence the project if carefully considered in context, but excessive technical debt can be depressing and chase away valuable talent to the competitors. This approach is based on the fact that mobile app development companies get more job satisfaction from the quality of their work than quantity.

Concisely, high technical debt lowers the chances of reuse and set low quality standards throughout the entire code base.

READING CODE IS NOT A WALK IN THE PARK

Mobile app developers get immense satisfaction when they provide credible solutions to difficult problems. However, writing an app code is easy, but reading and interpreting it correctly is not. This is one of the main reasons why most app developers prefer rewriting the entire code instead of spending hours reading and trying to comprehend what the existing code means.

If you come up with a code that you can hardly follow at the time, there is a high chance that you will not be able to understand it later on. Not being able to comprehend your own code weeks or months after you write it can be really demoralizing and depressing.

FOUNDATIONAL SKILL

Over the last three years, good software practices and ethics such as TDD and unit testing and professional refactoring have gained massive traction across the globe. These two practices help code maintainability and quality. Adhering to this code writing principles is a foundational trait or skill that pays the highest dividends later on especially when refactoring or testing the code.

Implementing clean code principles results in a source code that is highly modular and thus it becomes easier to not only test but also read.

THE PRIMARY AUTHOR OF THE CODE

Unknown to most mobile app developers is that other experts in the industry will read every line of code that they write 20 or more times during its lifetime. These experts will be working tirelessly to improve the app by incorporating new features or fixing bugs to promote its functioning.

Just like how renowned book authors who use short paragraphs, headings, and chapters to present their thoughts and ideas in an easy to understand format, mobile app development companies use a similar system. The only difference is that app developers use different terminologies to describe methods, classes, and namespaces.

CONCLUSION

Writing a clean code for a mobile app will not only help you create a project that is user-friendly, but also makes it easy for other app developers to implement changes in the future.
