What is Node.js (Express, NestJS)

Where Node.js helps a business

• The client's team already writes JavaScript and TypeScript and wants to maintain the back end themselves.
• The service has to hold many simultaneous connections: chats, notifications, real-time webhooks.
• The project already runs on Node.js and needs further work.

How we use it

Nuxt, which powers the studio website and the online store storefront, itself runs on Node.js to render pages on the server. But separate server logic we write in other languages: the store API in FastAPI, bots in Python, and the high-load Peregovorka chat in Go.

Common problems

• A zoo of languages. If the project already has a Python bot, a second server language doubles the maintenance.
• Builds need memory. A Nuxt build does not fit in a small server's memory, so we build the image on a workstation.

When you do not need it

If you have no JavaScript team of your own, the back-end language is better chosen for the task and for whoever will maintain it. We discuss that in a free audit under Websites.
