FAQs
NodeJS is an open-source, cross-platform, back-end JavaScript runtime environment. It executes JavaScript code outside of a web browser, allowing developers to use JavaScript for Server-Side App Development.
NodeJS is perfect for building real-time apps (like chat and streaming), APIs, and scalable backend systems that handle heavy traffic with ease.
JavaScript runs in browsers; NodeJS lets you run JavaScript on servers to power full web applications.
NodeJS Developers are software engineers who specialize in using the NodeJS runtime to build the backend (server-side) of web and mobile applications. They are experts in JavaScript, API design, and database management.
Both are used for Server-Side App Development. NodeJS is “asynchronous” or “non-blocking” by default, meaning it can handle many connections at once, which is ideal for real-time apps. PHP is typically “synchronous,” which makes it simpler for traditional, content-heavy websites (like WordPress).
Rates from leading firms in the USA usually range between $75 and $150 per hour. The total cost of a full-scale, custom enterprise application can vary from $75,000 to over $500,000, depending on factors like project size, complexity, and required integrations.
Express.js is the most popular, minimal, and flexible web application framework for NodeJS. It provides a simple set of tools for building web and mobile application APIs, and it is the de facto standard for NodeJS development.
