Node.js development: APIs, real time and applications

Node.js runs JavaScript on the server. It excels at APIs, real-time applications (messaging, notifications, live tracking) and integrations between services. Using the same language for the interface (React, Vue.js) and the server simplifies development and maintenance. Its library ecosystem (npm) is the largest there is; we choose carefully to avoid fragile dependencies.

Good fit

When to choose Node.js?

  • Real time

    Messaging, instant notifications, dashboards that update themselves.

  • An API

    For a mobile app, a React website or partners.

  • Integrations

    Connecting services together: payment, CRM, email marketing, AI.

  • A JavaScript team

    The same language from interface to server.

In all honesty

When it isn't the best choice

For very heavy calculations or data analysis, Python is often better suited. And for a classic management application, a PHP framework such as Laravel can be faster to set up.

Typical projects

What we build with Node.js

API for a mobile app

Accounts, data, payments, notifications.

Messaging or live tracking

Instant exchanges, delivery tracking, alerts.

Connectors between tools

CRM, shop, accounting and email marketing sync.

AI assistant

Chatbot connected to your documents and tools.

Existing code

Takeover, migration and maintenance

An old Node.js application often runs on an engine version that is no longer maintained, with abandoned libraries. We inventory the dependencies, replace the problematic ones, move to a maintained version and set up tests and monitoring.

Frequently asked questions

Frequently asked questions: Node.js

Both suit most projects. Node.js shines for real time and integrations; PHP for classic management applications and simple hosting. We follow your existing systems.

Yes, it runs services used by millions of people. Reliability mainly depends on code quality, tests and monitoring.

On a private server, a cloud service or a specialised hosting platform. Classic shared PHP hosting is usually not suitable.

Yes: audit, documentation, dependency updates, then maintenance.
