Why Choose an Experienced Node.js API Development Vendor?
Building a scalable Node.js API requires deep knowledge of async patterns, error handling, and database optimization.
IRPR has shipped 200+ Node.js APIs over the last 8 years. Every project follows a proven process: Idea, Roadmap, Product, Release. We use automated testing and CI/CD to catch bugs early.
Our senior engineers average 12+ years of experience. We deliver fixed-price quotes after a 2-week Roadmap phase. No hourly billing, no scope creep.
The Difference Between Generic Dev Shops and IRPR
Not all Node.js API vendors deliver the same quality. Here is what sets IRPR apart.
Generic dev shops often work hourly, skip documentation, and hand off untested code. IRPR treats your API as a product with full lifecycle support.
We produce OpenAPI specs, automated tests, and deployment scripts by default. You get source code ownership and a 30-day post-launch support period.
- Hourly billing with no cap
- No API documentation
- No testing strategy
- Unclear code ownership
- 6-12 month delivery
- No post-launch support
- Fixed price from roadmap phase
- OpenAPI 3.0 specs included
- Automated test coverage >80%
- Full source code ownership
- 8-12 week delivery
- Sentry monitoring + 30 day support
Our API Development Process
We follow a structured 4-phase process to deliver reliable Node.js APIs on time and on budget.
Phase 1 (Roadmap) takes 2 weeks and produces a fixed price, timeline, and architecture document. Phase 2 (Architecture) finalizes the data model, endpoints, and tech stack.
Phase 3 (Development) delivers code in 2-week sprints with demos. Phase 4 (Release) deploys to production with monitoring and a 30-day warranty.
What Ships With Every Node.js API
Every API project includes a complete delivery package, not just code.
You get everything needed to run and maintain the API independently. No hidden extras or add-on costs.
- Source code in your private GitHub repo
- OpenAPI 3.0 specification
- CI/CD pipeline with GitHub Actions
- Unit and integration tests (>80% coverage)
- Docker container setup for local development
- API rate limiting and JWT authentication
- Sentry error tracking and performance monitoring
- Postman collection with example requests
- Deployment scripts for AWS, GCP, or Azure
- 30 days of post-launch support
