Code Refactoring – How to Recognize the Need for It in Your Company? Step by Step
At Codema, a company with extensive experience in the IT industry, we understand the crucial role that code refactoring plays in maintaining the health and efficiency of applications. From our experience, there are several technical indicators that signal the need for refactoring. We would like to share our insights and practices that have helped us effectively improve our clients’ projects.
- Code complexity
At Codema, we recognize that increased code complexity can lead to problems. Therefore, we use metrics such as cyclomatic complexity to monitor and simplify code structures, enhancing readability and ease of maintenance.
- High number of errors
Regular occurrences of errors indicate problematic areas of code. At Codema, we employ continuous testing and code analysis to quickly identify and fix errors before they become critical issues.
- Application performance
Noticing a decline in application performance, we focus on optimizing and simplifying the code, often leading to improved operation speed and efficiency.
- Code duplication
At Codema, we emphasize the elimination of code duplication. We use tools for automatic detection and refactoring of repeating code segments, increasing project consistency and efficiency.
- Difficulties in extending functionality
When adding new features becomes challenging, we know it’s time for refactoring. We apply practices like modular design to facilitate extension and scaling of applications.
- Technological updates
In response to changes in external technologies, at Codema, we regularly update and adapt code to ensure compatibility and performance.
- Testing
We pay special attention to the ease of testing code. Refactoring at Codema includes creating code that is easier to test and maintain.
- Code clarity and documentation
We emphasize the importance of code clarity and documentation. At Codema, we regularly conduct code review sessions to ensure our code is understandable and well-documented.
- Size of classes and functions
We strive to keep classes and functions at reasonable sizes. We know that smaller, well-defined modules are easier to maintain and understand.
- Team feedback
At Codema, we value our team’s opinions. Regular meetings and technical discussions help us identify areas requiring refactoring.
As you can see, code refactoring is a key process that helps maintain the high quality of applications. Recognizing the need for refactoring requires analysis of application performance, evaluation of code quality, and user feedback. When the process is properly planned and executed, it can bring significant benefits to the quality and efficiency of applications.
At Codema, refactoring is not only a technical necessity but also an opportunity for continuous improvement and development of our projects. We offer comprehensive support to clients from the first contact, conducting audits and professional identification of refactoring needs in our clients’ companies. We will advise you on whether code refactoring is right for you and your company and the extent to which it should be conducted.
