Why Node.js

One runtime for APIs, streaming and edge on a single language

Node.js takes TypeScript from the browser to the server. Same mental model, same dependencies, deployment on any cloud and stable latencies under real load.

01

Full-stack TypeScript

Shared types between frontend and backend with tRPC, Zod and single schemas. Safe refactors, validated contracts and fewer errors at the API boundary.

02

Event-loop concurrency

Non-blocking model for thousands of simultaneous I/O connections: WebSockets, SSE, AI streaming and external API aggregation with stable latencies.

03

Native real-time

Socket.IO, Server-Sent Events and WebSockets over Fastify. Live notifications, real-time dashboards, agentic chat and event feeds with controlled backpressure.

04

Serverless and edge

Deployment on AWS Lambda, Cloudflare Workers and Vercel Edge. Tuned cold starts, native ESM and bundlers calibrated to start under 100 ms.

05

npm ecosystem with criteria

Audited dependencies, deterministic lockfiles and SBOM. Strict semantic versioning and scheduled updates every sprint.

06

BFF and orchestration

Backend-for-frontend that aggregates APIs, normalises contracts and caches responses. One call per view, tight payloads and Core Web Vitals protected.

Technical decision

The framework that fits your workload

Every Node.js project starts by choosing runtime and framework with criteria. Express, Fastify, Hono and serverless cover different scenarios. We decide with data.

Express

Classic REST API

Mature middleware, integration with existing ecosystems and a flat curve for mixed teams. Fits internal APIs, admin panels and progressive migrations.

Mixed teams · Internal APIs

Fastify

High throughput

JSON Schema validation, typed plugin system and performance measured in production. Fits public APIs with high RPS, BFFs and services with strict SLAs.

p95 < 50 ms · 10k+ RPS

Hono

Edge runtime

Lightweight framework compatible with Cloudflare Workers, Vercel Edge and Bun. Fits global APIs, smart redirects and geographically distributed middleware.

Global edge · cold start < 50 ms

Serverless

Lambda and Workers

Node.js functions on AWS Lambda and Cloudflare Workers with IaC in Terraform. Fits elastic loads, webhooks and on-demand event processing.

FAQ

What CTOs ask before signing

Concrete answers on performance, deployment and operations. Every Dinacode Node.js project ships with observability, CI/CD and living documentation.

  • When to choose Node.js over other backends?
    Node.js fits when the bottleneck is I/O: APIs that aggregate external services, real-time over WebSockets, AI streaming or BFFs for modern frontends. For CPU-bound loads we combine Node.js with workers or services in Go, Java or Quarkus as needed.
  • Which framework do you use: Express, Fastify or Hono?
    We decide by load and environment. Express for internal APIs and progressive migrations, Fastify when the SLA demands tight p95 and high RPS, Hono when deployment is edge over Cloudflare Workers or Vercel Edge. Each choice is documented in the technical proposal.
  • Do you work with end-to-end TypeScript?
    Yes. Shared types between frontend and backend with tRPC, Zod or OpenAPI schemas generated from code. The contract lives in one place and the refactor propagates at compile time.
  • How do you handle heavy tasks and background jobs?
    BullMQ over Redis for queues, retries and workflows. For long processes we delegate to dedicated workers, asynchronous AWS Lambda or separate services. The main event loop stays free to serve requests.
  • How do you deploy Node.js services?
    Three models depending on the case: Kubernetes containers for persistent services, AWS Lambda for elastic loads, Cloudflare Workers or Vercel Edge for low-latency global delivery. Infrastructure in Terraform and pipelines in GitHub Actions or GitLab CI.
  • What observability does each project include?
    OpenTelemetry as the standard: distributed tracing, metrics and structured logs. Integration with Grafana, Prometheus and Datadog. Alerts on p95, error rate and event-loop saturation from sprint one.
  • How do you guarantee performance under load?
    Benchmarks with autocannon and k6 before production. Event-loop profiling, connection-pool tuning, Redis caching and CDN. Every release passes load tests with real traffic data.
  • Do you work with legacy Node.js code?
    Yes. We audit the codebase, identify critical points and migrate by slices: callbacks to async/await, JavaScript to strict TypeScript, Express to Fastify when it adds value. Strangler fig on the existing monolith, with the business running.
