How long does it take to build a Node.js API?

Most APIs are delivered in 8-12 weeks. Simpler integrations can ship in 8 weeks; complex systems involving microservices or real-time processing take up to 12 weeks. IRPR has a 98% on-time delivery record.

What tech stack do you use for Node.js API development?

IRPR uses Express.js or NestJS for the API framework, PostgreSQL or MongoDB for data storage, Redis for caching, and Docker for containerization. For real-time features we use Socket.IO. For GraphQL we use Apollo Server.

Can you integrate the Node.js API with third-party services?

Yes, IRPR has built integrations with 50+ services including Stripe, Salesforce, HubSpot, Twilio, and AWS S3. We handle authentication, rate limiting, and error handling for each integration.

Do you build Node.js APIs for healthcare?

Yes, IRPR builds HIPAA-compliant Node.js APIs for healthcare clients. We use AWS KMS for encryption, HAPI FHIR for standard data exchange, and maintain audit logs. Our team has completed 3 HIPAA projects in 2024.

Who owns the code after the project?

You own everything — the full source code, documentation, and infrastructure configurations. IRPR does not license or reuse your code. We deliver the repository and all intellectual property upon final payment.

How quickly can we start?

We can begin the Discovery phase within 1-2 weeks of signing the contract. The total timeline to production is 8-12 weeks from kickoff. Contact us to schedule a free discovery call.

Do you offer ongoing maintenance after launch?

Yes, IRPR offers optional post-launch support plans starting at $5K/month. These include bug fixes, minor enhancements, and 24/7 incident response. You can cancel at any time.

Why Premium Node.js API Development Matters

A well-built API is the backbone of modern applications. Without it, you risk downtime, security gaps, and slow iterations.

IRPR has shipped over 200 production APIs for clients in 50+ countries. Every API undergoes load testing (k6), security audits (OWASP), and performance optimization before release.

Our APIs handle millions of requests per day with 99.9% uptime. We use Node.js clusters, Redis caching, and PostgreSQL connection pooling to ensure consistent speed.

Generic Dev Shop vs IRPR

Most agencies deliver APIs that break under load. We don't.

A generic shop writes endpoints fast but skips testing, documentation, and monitoring. You get code that works on a laptop but fails in production.

IRPR builds APIs that are production-ready from day one. Every endpoint is documented, tested, and monitored.

the difference

✗ Generic Dev Shop

No load testing before launch
Missing API documentation
No CI/CD pipeline
No error monitoring (Sentry, Datadog)
No security audit (OWASP)
No fixed timeline or price

✓ IRPR

Load tested with k6 (10,000 concurrent users)
OpenAPI 3.0 auto-generated docs
GitHub Actions CI/CD with deployment to AWS/GCP
Sentry error tracking + Datadog dashboards
OWASP security review and penetration testing
Fixed price and 8-12 week delivery

Our Node.js API Development Process

We follow a 4-phase process from idea to deployment.

Phase 1 (Idea): We define the API contract, endpoints, and data models with you. Phase 2 (Roadmap): We deliver a detailed spec with mockups and a fixed quote.

Phase 3 (Product): We build, test, and deploy the API in 6-10 weeks. Phase 4 (Release): We hand over code, documentation, and monitoring dashboards.

1. Discovery (1 week)

We interview stakeholders, review existing systems, and define API scope. Deliverable: API contract document with endpoints and data models.

2. Roadmap (1 week)

We produce a detailed technical spec with wireframes, cost breakdown, and timeline. You get a fixed price for the entire build.

3. Build (6-8 weeks)

Our senior engineers build the API in sprints. Every endpoint has automated tests and passes code review.

4. Release (1 week)

We deploy to production, configure monitoring (Datadog, Sentry), and hand over the repo. You own the code.
