The above implementation increased complexity. Use the following feature-based modularity for a rather readable code.
The current backend project structure needs to be refactored to improve readability, maintainability, and scalability. This refactor will involve modularizing the codebase by feature and making several other structural improvements to simplify future development and onboarding for new developers.
Further Modularity by Feature:
auth/
, spotify/
, and test/
.Flatten Middleware and Utility Structure:
authMiddleware.js
) into the respective feature directory.utils/
).Use Index Files for Imports:
index.js
files in each feature and utility directory to export all related modules.Document Folder Purpose:

Please assign this issue to the backend team and prioritize it for the upcoming sprint.
Description
Our backend codebase has grown, and the current flat file structure makes it challenging to manage and scale the application efficiently. To enhance maintainability, readability, and scalability, we need to reorganize the backend into a more modular structure. This refactoring will separate concerns, making it easier to add new features, fix bugs, and collaborate with other developers.
Tasks
Create a New Modular Project Structure
Organize the backend directory into the following subdirectories:
Move Existing Files to Appropriate Directories
.env.example
with all necessary environment variables.server.js
to the root of thebackend/
directory.spotifyRoutes.js
toroutes/spotifyRoutes.js
.auth.js
toroutes/authRoutes.js
.routes/index.js
to aggregate all routes.controllers/spotifyController.js
and move route handlers fromspotifyRoutes.js
.controllers/authController.js
and move route handlers fromauth.js
.spotifyClientCredentials.js
toservices/spotifyClientCredentials.js
.auth.js
toservices/authService.js
.services/spotifyService.js
for Spotify API interactions.middleware/rateLimiter.js
for rate-limiting middleware.middleware/authMiddleware.js
for authentication middleware.middleware/errorHandler.js
for global error handling.utils/logger.js
for logging utilities.models/user.js
for user schema (optional, for future use).Adjust Code to Match the New Structure
require
orimport
statements to reflect new file locations.server.js
to use the new routes and middleware.server.js
and require necessary services.Centralize Configuration
config/config.js
:Implement Middleware Functions
middleware/rateLimiter.js
.ensureAuthenticated
function tomiddleware/authMiddleware.js
.middleware/errorHandler.js
.server.js
.Isolate OAuth Code
services/authService.js
andcontrollers/authController.js
.routes/authRoutes.js
and do not interfere with current functionality.Update Environment Variables
.env.example
with placeholders for all required environment variables..env
files are listed in.gitignore
to prevent sensitive data from being committed.config/config.js
for accessing environment variables.Test the Application
