Node.js Development Company

The perfect tool for data-intensive applications

Node.js is an open-source, cross-platform JavaScript runtime environment that executes code outside of a browser. It is commonly used for creating scalable, server-side web apps. Node.js is built on the V8 JavaScript engine from Google Chrome and provides an event-driven, non-blocking I/O model that is efficient and lightweight for real-time applications. It is commonly used by Netflix, LinkedIn, Uber, eBay, and even NASA.

Node.js is an open-source, cross-platform JavaScript runtime environment that executes JavaScript code outside of a browser. It is commonly used for creating scalable, server-side web apps. Node.js is built on the V8 JavaScript engine from Google Chrome and provides an event-driven, non-blocking I/O model that makes it efficient and lightweight for real-time applications. Nest.js, on the other hand, is a framework for building server-side applications using Node.js. It is built on top of Express.js, a popular web application framework for Node.js. Nest.js provides a robust set of features and architectural patterns, inspired by Angular, to help developers create scalable and maintainable applications. Nest.js supports a wide range of features out of the box, including routing, middleware, authentication, database integration, and more. It also has a vibrant and active community, with a rich ecosystem of plugins and libraries that extend its capabilities. Overall, Node.js and Nest.js together provide a powerful platform for building server-side applications in JavaScript, allowing developers to leverage their skills and knowledge of the language across the entire web development stack.
To hire Node developers, consider using online catalogues like Clutch or Goodfirms, attending relevant events and conferences, or searching for Node.js development companies online. Review their portfolio, dedicated developers, blog, and testimonials from clients to assess their experience, expertise, and customer satisfaction before making a decision.
