Node.js in our architecture
Node.js powers server execution for HiMat web products: Next.js route handlers, middleware, cron-friendly scripts, and standalone API services when deployment should scale independently from the frontend.
TypeScript end-to-end reduces context switching for full-stack squads—shared types between client forms and API validation schemas.
We confirm Node.js because Next.js server runtime and tooling in this repo depend on it, even when clients never touch raw http servers directly.
What we build on Node.js
REST and occasional GraphQL APIs with explicit versioning and OpenAPI docs when partners integrate.
Webhook receivers with signature verification, idempotency keys, and retry-safe processing queues.
Background jobs—email sends, report generation, ingest pipelines—using scheduler platforms or queue workers appropriate to scale.
Auth sessions, OAuth callbacks, and API key management with rate limits.
AI orchestration routes that call OpenAI or OpenRouter with server-held keys, never exposed to browsers.
Reliability and security
Secrets live in environment variables or managed secret stores—not committed configs. Rotation playbooks are documented at handoff.
Input validation uses schema libraries; SQL or NoSQL injection risks are addressed per datastore.
Structured JSON logging aids support, with redaction filters for emails, tokens, and payment identifiers.
Load characteristics drive hosting choice: serverless functions for spiky marketing forms, long-running Node services for websockets or heavy CPU when required.
When Node.js is the right call
Node.js fits when your team already invests in JavaScript/TypeScript and wants one language across UI and API—common for SaaS and content-heavy apps.
When Python or Go services already exist, we integrate via HTTP rather than rewriting—Node.js handles the web tier only.
