Are you concerned about issues, maintenance, and crashes in your Ruby on Rails application? It may be time to review the code quality of your application.
Before making any business decisions, it is always preferable to thoroughly understand the problem. But what if you could go further and prevent those problems from the start? This is where maintaining code quality in your Ruby on Rails application comes into play. When the code in your application is of excellent quality, it performs optimally.

Mallow has been in custom software development for over a decade, and we strongly believe in the importance of adhering to best practices to maintain code quality for all applications. We have witnessed this approach consistently improve the overall quality of the application, as this ultimately results in reduced maintenance hours and a better user experience.
After going through this article, you will understand how to measure the quality of your Ruby on Rails application’s code and discover useful tools that can assist you in the evaluation process.
What attributes define a code with high quality?
Smooth operation and long-term success of your application rely heavily on the quality of the code. Well-written and readable code, adherence to coding standards and best practices, appropriate documentation, efficient algorithms, and effective error handling are some important aspects of code with good quality.
Below mentioned are some points that give you an overview of the fundamental characteristics associated with good code quality.
Efficiency: Good code quality promotes efficient algorithms and data structures, minimising unnecessary computations and reducing time complexity. It emphasises proper resource management, such as efficient memory allocation and deallocation, preventing memory leaks and optimising resource utilisation.
Maintainability: High-quality code is characterised by its ease of maintenance. It is modular, comprising clearly defined interfaces facilitating communication between different components. Modifications can be made to the code without causing disruptions to other parts of the system.
The code should convey business logic : In many instances, you can’t always expect the same developer to take up your application’s task every time. And for you to not spend much on the development costs, the newly onboarded developers should be able to understand the code and business logic behind it clearly and start the development quickly.
Reliability and Reusability: An application’s code could be considered reliable if it works as intended and does not crash, hang, or produce unexpected results. It should handle error conditions gracefully and not introduce new bugs or security vulnerabilities.Reusability means the code can be used in different parts of the system or different systems altogether. It is designed with abstraction and encapsulation in mind, making it easy to reuse without modification.
Scalability: The application has been built with code that can handle increasing traffic and usage levels without degrading performance or stability.
Testability: When code is easily testable, it indicates it is well-structured, modular, and follows good coding practices. Testable code is designed to allow for comprehensive and efficient testing, enabling developers to write meaningful tests and identify potential issues early on. High testability promotes the codebase’s maintainability, extensibility, and robustness.
Security: Security scanning is a crucial aspect of ensuring the integrity and protection of code against potential vulnerabilities such as injection attacks, XSS and CSRF and other malicious attacks. It involves evaluating various security aspects, such as input validation, access control, and data encryption, to identify potential weaknesses that can be exploited.
