Node.js Folder Structure
If you are new to Node.js, it can be daunting to create a folder structure that will work for your project. The structure you choose will depend on the size and complexity of your project. Here are some common approaches:
Basic Structure
The simplest approach is to have a single file, index.js
, in the root of your project. This file will contain all your code. This works well for small projects, but as your project grows, it becomes harder to manage.
index.js
Modular Structure
A more organized approach is to split your code into modules. Each module should have a specific responsibility. This makes it easier to maintain and test your code.
Your folder structure might look like this:
app.js
: This is the main file where you set up your app.routes/
: This folder contains all your route files.models/
: This folder contains all your database models.views/
: This folder contains all your view files.
app.js
routes/
index.js
models/
user.js
product.js
views/
home.ejs
about.ejs
Layered Structure
For larger projects, a layered structure may be more appropriate. This approach separates your code into layers: presentation, business logic, and data access.
Your folder structure might look like this:
app.js
: This is the main file where you set up your app.presentation/
: This folder contains all your view files.business/
: This folder contains all your business logic files.data-access/
: This folder contains all your data access files.models/
: This folder contains all your database models.
app.js
presentation/
views/
home.ejs
about.ejs
business/
services/
user.js
product.js
data-access/
repositories/
user-repo.js
product-repo.js
models/
user.js
product.js
Choose the folder structure that works best for your project. The most important thing is to keep your code organized and manageable.
