I'm getting pretty comfortable with writing functions and classes in languages like Python and JavaScript. I can tackle coding challenges easily, but I really struggle when it comes to structuring a project folder for a more substantial application. Tutorials often keep things in one or two files, but I see examples on GitHub with lots of folders like src, lib, utils, assets, components, and services. I end up overwhelmed, and my projects often turn into huge files with hundreds of lines because I'm scared of splitting my code incorrectly or causing issues like circular imports. How did you learn about effective project architecture? Are there any standard structures you follow for your coding projects, or do you just wing it?

Often, architecture evolves from real problems rather than being a strict plan from the get-go. For example, you might start with a few basic pages and then notice similarities that lead you to refactor into a shared structure. This naturally justifies organizing files into categories like public endpoints and internal code. Instead of stressing about rules, keep asking yourself questions like, 'Who needs to access this?' or 'What belongs together?' If you find yourself staring at a long file, that's usually a sign that it's time to split things up logically based on your needs.
Transitioning from writing scripts to managing proper projects is a big step. My advice would be to start off simply and allow your structure to develop organically. Check out some small open-source projects for inspiration, and let your organization improve as your project grows. With experience, it'll become much easier to determine what folder structures work best for you.
The best way to learn project structure is through time and experience, plus working on larger projects with other developers. If you're looking for a specific structure, Java has a pretty solid one you can follow. Play around with various setups, and definitely use a good IDE like IntelliJ that lets you refactor easily if you don't like your organization. When it comes to functions, try to keep them small and manageable. The simpler the function, the easier it is for someone else (or future you) to understand what it does. Avoid long, complicated functions as they tend to lead to more bugs. Good code is often boring and straightforward!
Absolutely! Keeping it simple is like assembling a jigsaw puzzle.
Remember that the directory structure is there to help you understand your project better. Take a step back and analyze existing projects on GitHub. Ask yourself why certain files are in particular places. Sometimes it's all freeform, while other times it's shaped by the language or framework you're using. For example, Go projects usually follow a standard setup, while Python projects can be more flexible. To start, you might want to mimic a project structure that aligns with your language or genre. As you grow, remove what you don't need or create directories that make your work easier. Ultimately, your directory should reflect what helps you the most!
That's such a great point! Each time I refactor, the folder structure gets clearer.
