FAQ

Frequently asked questions about Node.js Development

  • Yes, companies like Netflix, PayPal and LinkedIn use Node.js in large-scale production. With a well-designed architecture (microservices, message queues), Node.js scales perfectly.

  • A basic REST API with authentication and CRUD starts from 3,000EUR. Complex APIs with microservices, WebSocket and message queues can reach 15,000EUR or more.

  • Node.js is ideal for real-time applications, high-performance APIs and when the frontend uses JavaScript. Python is better for machine learning and heavy data processing. We advise you based on your case.

  • Yes, we set up CI/CD pipelines, Docker, monitoring with PM2 or similar, and automated deployment on AWS, Google Cloud or any cloud provider.

  • Yes, we perform migrations from PHP, Java, .NET or other languages to Node.js. We plan the migration in phases to maintain service continuity.
