Node.js

Node.js development services

APIs, real-time systems, and backend services in the same language as your frontend, built to hold up under real traffic.

What is Node.js?

Node.js is a JavaScript runtime for building server-side software: APIs, background jobs, and real-time services that run outside the browser. Codiot builds Node backends for products that already run JavaScript on the frontend, so one team and one language cover the whole stack, and for systems where large numbers of concurrent connections matter more than raw per-request computation.

What we build

Real projects, not a tech-stack badge.

REST and GraphQL APIs

Typed, documented APIs with authentication, validation, and error handling designed in rather than bolted on.

Real-time features

WebSocket services for chat, live dashboards, notifications, and collaborative editing, where holding many open connections cheaply is the whole point.

Backend for frontend

A Node layer that shapes data specifically for your web or mobile client, so the frontend stops stitching together five upstream calls.

Integrations and background jobs

Queues, scheduled work, webhooks, and third-party integrations that retry properly and fail visibly.

The honest take

When this is the right choice, and when it isn't.

Good for

Teams already shipping JavaScript or TypeScript on the frontend, products with real-time or high-concurrency requirements, and API layers that need to move as fast as the product does.

When not to use it

CPU-heavy work such as large-scale data processing, video encoding, or numerical computation. Node's single-threaded event loop is built for waiting on input and output, not for sustained computation, and a different runtime will serve you better.

TypeScript by default, so the contract between frontend and backend is checked rather than assumedInput validated at the boundary, never trusted from the clientStructured logging and error tracking wired in before launch, not after the first incidentLong-running work moved to a queue instead of blocking a requestDependencies kept few and current, because every package is code you now own

FAQ

Common questions, answered plainly.

Is Node.js good for production backends?

Yes, and it is widely used for exactly that. It suits APIs, real-time services, and integration layers particularly well because it handles many concurrent connections cheaply. The caveat is computation: heavy CPU work blocks the event loop, so that work belongs in a queue, a worker, or a different runtime.

Node.js or .NET for a backend?

Node fits when your team already writes JavaScript or TypeScript, when the work is input and output heavy, or when you want one language across the stack. .NET fits when you are in the Microsoft ecosystem, need heavier computation, or want its stronger built-in structure for large enterprise systems. Both are sound; the deciding factor is usually your team and your existing stack.

Can you work on our existing Node codebase?

Yes. Most Node engagements start with a short audit of what exists: dependency health, test coverage, error handling, and the parts that make changes risky. We then extend it or replace pieces incrementally rather than proposing a rewrite by default.
