Node.js
Fast back ends, real-time features and one language across your whole stack.
Node.js runs JavaScript on the server. We use it for APIs, SaaS back ends and anything that needs live updates, and because your front end speaks the same language, one team can move across the whole product.
import express from 'express';import { db } from './db';const app = express();app.use(express.json());app.post('/orders', async (req, res) => { const order = await db.order.create({ data: req.body }); io.emit('order:new', order); res.status(201).json(order);});app.listen(3000);- 2009First released

What we build with Node.js
Server-side work that stays fast under load and is simple for the next developer to pick up.
Web apps & SaaS back ends
Accounts, billing, permissions and the business logic behind your product, written in TypeScript and easy to extend.
REST & GraphQL APIs
Clean, documented APIs for your web and mobile apps, and for partners who need to connect to you.
Real-time apps
Chat, live dashboards, notifications and collaborative editing over WebSockets, one of the things Node.js does best.
Microservices & serverless
Splitting a large system into services, or running functions on AWS Lambda, when it genuinely makes things simpler.
E-commerce back ends
Carts, checkouts, stock and order flows, connected to Stripe, shipping providers and your warehouse.
IoT back ends
Services that collect data from connected devices, process it as it arrives and push commands back.
Migration & upgrades
Moving an old PHP or Java back end to Node.js, or bringing an outdated Node.js app up to a supported version.
Support & dedicated team
Monitoring, security patches and dependency updates, or Node.js developers who work as part of your team.
Node.js vs. a thread-per-request server
Where Node.js’s event loop helps, and the one place it needs care.
Open connections per server
Non-blocking I/O holds thousands of sockets cheaplyReal-time features
WebSockets and live updates are a natural fitCode shared with the front end
Same language and types on both sidesHeavy number-crunching
We move it to worker threads or a separate service
Key things to know about Node.js
Node.js is an open-source runtime that runs JavaScript outside the browser, built on the V8 engine from Chrome. Most of our Node.js work is written in TypeScript, which adds types and catches mistakes before they reach production.
It handles many requests at once without waiting on each one. That makes it a good fit for APIs, real-time features and services that spend their time talking to databases and other systems.
For long, CPU-heavy calculations (video encoding, large reports) we move the work into background jobs or a separate service, so the API stays quick for everyone else.

How a Node.js project runs
Four stages, with working endpoints you can try from the first sprint.
- 01
Map the system
We look at who calls your back end, what data it owns and what it connects to, then agree the scope.
- 02
Design the API
Endpoints, data models and error handling are written down first, so front-end work can start in parallel.
- 03
Build and review
Two-week sprints, code reviews on every change, and a staging environment you can use at any time.
- 04
Launch and monitor
Load testing before go-live, then logging, alerts and uptime monitoring so problems are caught early.

Node.js questions
What is Node.js used for?
Mostly for back ends: APIs, SaaS platforms, real-time features like chat and live dashboards, and services that connect other systems together.
Is Node.js fast enough for a large product?
Yes, for the kind of work most products do: handling requests, reading and writing data, calling other services. Netflix, PayPal and Walmart run large parts of their platforms on it.
Do you use JavaScript or TypeScript?
TypeScript, unless you have a reason not to. It catches a whole class of bugs before release and makes the code easier for the next developer to understand.
Can you work on our existing Node.js code?
Yes. We begin with a short audit of the code, dependencies and infrastructure, fix anything urgent, and then continue with your roadmap.
How long does a Node.js back end take to build?
A focused API for an MVP usually takes 6–10 weeks. Larger platforms with many integrations take 3–6 months. You get a timeline before work starts.
