Node.js lets one team own the whole stack in one language. Its event-driven runtime suits the I/O-heavy API and real-time workloads most of our clients actually run. It is a poor fit for CPU-bound number crunching, and we will say so.
When to Choose Node.js
Reach for Node.js when the work is I/O-bound: APIs, real-time feeds, integrations, BFF layers. Sharing TypeScript types between client and server saves real time.
Core Technical Strengths
- Excellent throughput on I/O-bound APIs
- Shared TypeScript types across client and server
- First-class real-time support with WebSockets
- Fast cold starts for serverless deployments
Common Enterprise Use Cases
- REST and GraphQL APIs
- Real-time chat, notifications and live dashboards
- Backend-for-frontend and API gateway layers
- Third-party integration and webhook services
