I have a solid grasp of programming principles and can write functions and classes in languages like Python and JavaScript. However, I'm struggling with how to structure my project folders when I try to build a full application. While tutorials often show everything in one or two files, my experience with GitHub shows a variety of folder structures including src, lib, utils, assets, components, and services. This leaves me confused, and I often end up with a single, overwhelming 500-line file because I'm afraid of splitting things up incorrectly. I'm wondering how others learned proper project architecture. Is there a specific structure for the languages I use, or do people just figure it out as they go along?

Remember, the directory structure should primarily help you understand your own project better. Look at existing projects on GitHub and question why each folder is there. Some languages, like Go, have more rigid structures, while Python allows for a looser arrangement. Start with a project similar to yours, emulate its folder structure, and modify it as needed. If something isn't necessary, don't hesitate to remove or consolidate it! Ultimately, your code's functionality is what really matters.
The best way to learn project structure is through experience—working on real projects and experimenting. A good approach is to look at Java projects, which tend to have a clear and consistent folder structure. IDEs like IntelliJ can also help by allowing you to easily refactor your code when you're unhappy with its organization. Focus on breaking your code into smaller, manageable functions. The simpler and clearer your code, the easier it will be for others (including your future self) to understand.
Transitioning from scripts to projects can be tough! The key is starting simply and allowing your folder organization to develop based on your project's growth. Checking out small open-source projects can provide insight and inspiration for structuring your own work as you refine it over time.
What helped me was understanding that a project's architecture grows from real needs rather than strict upfront rules. For instance, if you notice duplicate code, that might suggest you need to refactor and create shared components. Keep asking yourself questions like 'Is this file publicly accessible?' and 'What changes together?' This will help you group files effectively without overcomplicating things from the start.
Exactly! Starting with two pages can quickly reveal structural needs, and you can build from there.

Absolutely, breaking code into small pieces is like solving a jigsaw puzzle!
