Understanding the Folder Structure

The importance of folder structure

The importance of creating a good architecture in a Node.js project can’t be overemphasized. This will determine if the project can scale and stand the test of time as the application begins to grow and more features need to be added. Some of the reasons for having a good folder structure or architecture in a Node.js project include the following:

• Separation of concern. This helps to reduce duplication of work, i.e., the codebase will become maintainable.
• Easy implementation of business logic.
• Programming practices like “don’t repeat yourself” (DRY), dependency injection, singularity of purpose, etc., can be implemented in the project.

The structure of our Node.js application

The code below shows the structure of the backend folder in our course management application using Node.js. Next, we take a closer look at the function each folder and file performs.
