Why Node.js for API Development
Node.js offers non-blocking I/O and a rich ecosystem for building fast, reliable APIs.
Node.js handles thousands of concurrent connections with minimal overhead. Its event-driven architecture makes it ideal for real-time applications and microservices. The npm ecosystem provides mature libraries for auth, validation, and database access.
IRPR has shipped 200+ Node.js APIs for startups and enterprises alike. Our APIs consistently achieve 99.9% uptime and sub-200ms response times at peak load. Every API is built with security, monitoring, and documentation from day one.
Choosing the Right API Partner
Not all Node.js developers deliver production-grade APIs.
Generic freelancers often skip security audits, rate limiting, and proper documentation. This leads to fragile APIs that break under load and create technical debt.
IRPR builds APIs that are secure, documented, and ready for scale. Every project includes a security audit in the Roadmap phase, automatic documentation generation, and a full CI/CD pipeline.
- No security audit
- No rate limiting built in
- No OpenAPI documentation
- No CI/CD pipeline
- No error monitoring
- No SLA
- Security audit in every Roadmap phase
- Built-in rate limiting and authentication
- Swagger/OpenAPI docs auto-generated
- CI/CD with GitHub Actions and Docker
- Sentry error tracking included
- 99.9% uptime SLA
How We Build Your Node.js API
Four phases from idea to production.
Our process begins with a 2-week Roadmap phase where we define architecture, data models, and endpoints. You get a fixed price and timeline before any development starts.
We then iterate in weekly sprints, delivering a working API at each step. Post-launch we provide monitoring, load testing, and a 3-month warranty.
What You Get When You Ship
Every Node.js API project includes these deliverables by default.
No hidden costs or missing pieces. The code is yours from day one.
- Source code in your GitHub repo
- CI/CD pipeline (GitHub Actions + AWS/GCP)
- Sentry error tracking setup
- Swagger/OpenAPI documentation
- Postman collection for all endpoints
- Load testing report (k6 or Artillery)
- Deployment scripts and runbooks
- Security audit report (OWASP top 10)
- Schema ERD and data flow diagrams
- Admin dashboard (if applicable)
