Why choose an expert Node.js API development studio
IRPR has shipped 200+ Node.js APIs for clients in 50+ countries. Here are the numbers that matter.
We focus on Node.js API development exclusively. Our team averages 10+ years of experience with Node.js, Express, and GraphQL. Every API is built with security, performance, and maintainability in mind.
Clients choose IRPR because we deliver on time and on budget. 98% of our projects ship within the original timeline. Our fixed-price model means no surprise invoices.
The difference between a generic dev shop and an expert Node.js API studio
Not all API developers are equal. Here is what sets IRPR apart from typical agencies.
Generic dev shops often bill by the hour and give you a junior developer. They skip documentation and monitoring. You end up with an API that breaks in production and no one to fix it.
IRPR is different. We assign senior Node.js engineers only. We ship OpenAPI documentation, CI/CD pipelines, and monitoring from day one. Your API is production-ready from the first deploy.
- Hourly billing with no cap
- No API documentation
- No security audit
- No CI/CD pipeline
- No monitoring or alerts
- No post-launch support
- Fixed price from day one
- OpenAPI 3.0 documentation included
- Security review with OWASP top 10
- CI/CD pipeline on GitHub Actions
- Sentry error tracking and Datadog monitoring
- 30 days post-launch support
Our Node.js API development process
Every API project follows a structured 4-step process. This guarantees clarity, speed, and quality.
We start with a 2-week Roadmap phase where we define the API architecture, endpoints, data models, and compliance requirements. You get a fixed price and a detailed timeline.
Then we build your API in 8-12 weeks with weekly demos. You see progress every Friday. We deploy to a staging environment so you can test live.
What ships with every Node.js API project
When you hire IRPR as your expert Node.js API development studio, you get more than just code.
We believe in shipping a complete product. That means documentation, tests, infrastructure, and monitoring are included by default. There are no hidden line items.
Everything below is part of the fixed price. You own all of it from day one.
- Source code in your private GitHub repo
- OpenAPI 3.0 specification
- Postman collection with examples
- Unit tests with Jest (90%+ coverage)
- Integration tests for all endpoints
- CI/CD pipeline on GitHub Actions
- Docker containerization with docker-compose
- Sentry error tracking
- Datadog monitoring dashboard
- Deployment guide for AWS/GCP/Azure
