Finding the Ideal Location for Controllers in an Express.js Project

I'm relatively new to software development and one concept that I find challenging is organizing the directory structure of various projects. As I prepare to embark on an Express project, I prefer keeping controller classes separate from route callbacks for better organization. However, I am unsure about the ideal location to place my controllers within the project. Currently, my project structure looks like this:

.
├── bin
├── config
├── controllers
├── migrations
├── models
├── public
│   ├── images
│   ├── javascripts
│   └── stylesheets
├── routes
├── seeders
└── views

The Sequelize CLI generated this structure, but I inserted controllers into the main directory. Should I move controllers to a src folder instead? I would appreciate any guidance on how to optimize this setup efficiently. There are numerous opinions and conflicting information available, so clarity on this matter would be invaluable. Thank you.

Answer №1

When it comes to organizing Express projects, there is no definitive standard structure to follow. The flexibility allows developers to arrange their projects in a way that makes sense and is easy to understand. In your situation, having controllers in the controllers/ directory is perfectly acceptable for a few reasons:

  1. It's logical to separate logic into distinct files
  2. The purpose of the controllers/ directory is clear from its name
  3. Files within controllers/ can be effortlessly imported into routes/ files

Therefore, sticking with this setup is fine. However, don't hesitate to reorganize if you start to feel overwhelmed by your project - remember, there are no strict rules to adhere to.
