Node.js development

Node.js runs JavaScript on the server, so the same language, and sometimes the same code, covers both ends of your product. It is fast for the input and output heavy work most web apps do, and it lets a smaller team own the whole stack without switching languages.

Where it fits

When Node.js is the right choice

You want one language across the front-end and back-end, so a small team can move fast.
Your backend mostly handles requests, APIs and real-time updates rather than heavy computation.
You need real-time features like live updates or chat, where Node's model fits naturally.
You value a vast package ecosystem and a large talent pool.

Where it does not

When we would reach for something else

For data science, machine learning or AI-heavy work, we keep that on Python and let Node handle the web layer.
For computation-bound number crunching, a compiled language will use your servers more efficiently.
If your team's strength is another backend language, the gain from switching rarely covers the cost.

Our approach

How we build with Node.js

We build Node.js services in TypeScript, with a clear structure, sensible error handling and tests around the parts that matter. We use it where sharing code and skills across the front-end and back-end pays off, and we keep the heavy data or AI work in the language best suited to it. Everything ships documented and yours to run.

Common questions

Node.js FAQ

Node.js or Python for our backend?

If your product is mostly web and real-time work and you want one language across the stack, Node.js is a strong fit. If it leans on data, machine learning or AI, Python is usually better. Many systems use both: Node for the web layer, Python for the intelligence. We will recommend the split that fits your product.

Is Node.js fast enough for production?

For the request-and-response work most web apps do, yes, and it handles many simultaneous connections well. Where raw computation is the bottleneck, we move that specific work to a better-suited tool rather than forcing everything through one language.

What about Express or NestJS?

Those are the frameworks we build Node services with: Express when we want something lightweight and explicit, NestJS when a larger app benefits from more structure. We choose based on the size and shape of the project.
