Part 1: Code Structure and Organization

Ilya Pavlov

Good code organization is crucial for the readability and maintainability of my projects. Read more about code structure and organization in this blog.

Monolithic files

Combining all routes and logic into a single file often leads to cluttered and hard-to-read code. This can result in frustration for both developers and users. According to coding standards, it is better to split the code into logical modules. Instead of one large file for a web application, it is recommended to split the code into separate files for routes, controllers, and models. This makes it not only more organized but also easier to make changes.

Confusion of responsibilities: Combining different responsibilities in the same function makes the code harder to test and maintain. It is important that each function has a single responsibility, which aligns with the SOLID principle of Single Responsibility. For example, instead of a function that both fetches and processes data, two separate functions can be created. This makes testing and reusing the code easier.

Lack of modularity

Not separating different logic can lead to code duplication and difficulties in reusing code for other purposes. By using modules and components, reusable code can be created that can be applied across different projects. This saves time and reduces the chance of errors.

Poor file organization: Not organizing code into logical modules or folders can make the codebase difficult to navigate. It is essential that projects have a clear folder structure so developers can easily find the files they need. This includes using clear and descriptive file names, which promotes collaboration within teams.
