Node JS is the event-driven JavaScript runtime powering modern web APIs, real-time systems, streaming applications, and tool-using AI agents. UpWve Technologies ships typed TypeScript services on NestJS, Fastify, and Express — with BullMQ queues, Prisma / Drizzle ORMs, Socket.io / native WebSockets, and full observability through OpenTelemetry and Sentry.
Our Node JS tech stack
The modern Node ecosystem we ship production backends with.
Our Node JS development services
REST and GraphQL APIs, real-time systems, microservices, queue workers, AI gateways, and full-stack Node + Next platforms.
REST & GraphQL APIs
Typed Node APIs with NestJS or Fastify, DTOs validated by Zod, OpenAPI auto-documentation, and authentication middleware ready for production.
Microservices
NestJS or Fastify microservice architectures with typed message contracts over RabbitMQ / NATS / Kafka, distributed tracing, and contract testing.
Real-Time & WebSockets
Chat, collaboration, live dashboards, and presence systems with Socket.io, native WebSockets, or WebTransport. Horizontally scaled through Redis adapters.
Queue Systems
High-throughput background job pipelines with BullMQ / Temporal — scheduled jobs, retries, dead-letter queues, and Horizon-style dashboards.
Full-Stack Node + Next
End-to-end TypeScript platforms with Next JS on the front and Node microservices or tRPC on the back — shared types, shared validation, one codebase.

Node backend cost is quoted per project and depends on scope, load profile, integrations, and data sensitivity. We tailor the scope to your budget. Written estimate within 48 hours, free, with no obligation.
Focused APIs: 4–8 weeks. Real-time systems: 8–12 weeks. Microservice platforms: 12–20 weeks. Staging live by end of week three.
NestJS for large, opinionated codebases with DI, modules, and long lifespans. Fastify for high-throughput APIs where raw performance matters. Express when we're maintaining existing code. We pick per project.
Yes. Every new project is TypeScript with strict mode, Zod / Valibot runtime validation, ESLint, and Prettier. No JavaScript-only codebases for new work.
Socket.io or native WebSockets with a Redis adapter for horizontal scaling. We also build with WebTransport or SSE where they fit better, and pair with BullMQ for durable background workflows.
Prisma for rapid velocity and strong migrations; Drizzle for raw SQL control and tighter performance. For very write-heavy or analytical workloads we also reach for Kysely or raw SQL with typed wrappers.
Clustering, horizontal scaling behind an ALB / Ingress, Redis-backed sessions, BullMQ for queue-driven workflows, PostgreSQL read replicas, caching tiers, and OpenTelemetry-driven profiling. We benchmark before we optimize.
Vitest or Jest for unit and integration tests, Supertest for HTTP, contract tests for services, and Testcontainers for real-database integration tests. CI runs the suite plus TypeScript strict and ESLint on every PR.
Yes. Docker images, Kubernetes (EKS / AKS / GKE / on-prem), serverless on AWS Lambda / Vercel / Cloudflare, Terraform-managed infra, and GitHub Actions / GitLab CI pipelines.
Yes. Typed OpenAI / Anthropic / Gemini clients, streaming SSE endpoints, LangChain.js / LlamaIndex.ts RAG, typed tool schemas via Zod, and LangSmith / Helicone tracing.
Yes. 90 days of post-launch support included, then an optional retainer covering on-call, P1 SLAs, Node LTS upgrades, dependency hygiene, and monthly performance reports.
You do. Full IP assignment on invoice — source, infra-as-code, CI/CD, and every typed package we publish.
