Frequently Asked Questions

“We built strategies before development that work just for you.”

How does Node.js handle concurrency and scalability?

Node.js is designed to handle concurrency and scalability by using an event-driven, non-blocking I/O model. This means that Node.js can handle multiple requests simultaneously and respond to them in real-time, which makes it ideal for building scalable applications. Additionally, Node.js has a built-in cluster module that allows us to easily scale your application across multiple CPU cores.

What makes Node.js suitable for developing large-scale enterprise applications?

Node.js can be used to develop large-scale enterprise applications, particularly those that require high scalability and real-time data processing. As Node.js supports high-speed code execution, it has been used by large companies such as Walmart, Netflix, and PayPal to develop high-performance, scalable applications.

What makes Node.js web development so popular?

Due to its popular frameworks and libraries used in web development, it has gained some popularity. This includes Express.js, Koa.js, and Hapi.js for building web applications as well as Socket.io for real-time communication between clients and servers.

Can you build a Frontend with Node.js?

Our experienced developers can build both frontend and backend applications with the help of Node.js runtime using only JavaScript. Thus, eliminating the need to switch contexts between various languages.

How do you take care of intellectual property rights?

At the outset of every project, we establish a Non-Disclosure Agreement with each client to uphold strict confidentiality standards. Our commitment to safeguarding our clients’ information and intellectual property is of the utmost importance to us, and we take every precaution to ensure that it remains secure and private.
