Hostinger’s platform offers scalability, full control, and industry-standard KVM virtualization. Browsers like Chrome and Firefox have runtime environments. Before Node.js was created, JavaScript could only run in a browser. Node.js handles JSON with ease, both in its native modules and in the ecosystem. Since JSON is the standard format for data exchange in web applications, this feature simplifies the development of APIs and interaction with databases.
- By separating the two, you can run multiple instances of your app on different servers, which can help to distribute the load and improve performance.
- Stat() method returns an object that contains information about the file, such as the file size, creation date, and modified date.
- Node.js uses an event-driven, non-blocking I/O model that allows it to handle I/O operations more efficiently.
- Buffers only deal with binary data, and it can not be resizable.
- Type npm -v in CMD or terminal and press Enter to check the version of npm for Node.
- Once you have Node.js installed, you can start building and running applications easily.
Event-driven
For example, let’s say you are writing a program and you need it to do the following. It should read some text from a file, print that text to the console, query a database for a list of users and filter the users based on their age. Did you know that you can master Node.js by combining official tutorials, interactive platforms like NodeSchool, and practical projects? Engage with the community through forums, meetups, and open-source contributions. All in all, Node.js empowers developers to create innovative and scalable web applications. By embracing these techniques, developers can create highly responsive and scalable Node.js applications.
How to download and install Node.js
Authentication is the process of verifying a user’s identity while authorization is determining what actions can be performed. We use packages like Passport and JWT to implement authentication and authorization. The tls module provides an implementation of the Transport Layer Security (TLS) and Secure Socket Layer (SSL) protocols that are built on top of OpenSSL.
What is a first-class function in Javascript?
On the other hand, managing packages with npm is vital for Node.js developers, simplifying dependency handling. Node.js has disrupted traditional server-side development with its asynchronous, event-driven approach, challenging established technologies like PHP, Java, and C#. It has a strong focus on asynchronous and I/O, this gives node access to the underlying computer operating system, file system, and networking. Number of IDEs such as Atom, JetBrains WebStorm, NetBeans, and Visual Studio Code support development of Node.js applications. Cloud-hosting platforms like Google Cloud Platform and AWS Elastic Beanstalk can be used to host Node.js applications.
Asynchronous
This prevents any blocking and enables other code to run junior node js developer in the meantime. An event-driven programming approach uses events to trigger various functions. An event can be anything, such as typing a key or clicking a mouse button.
By run-time environment, the infrastructure to build and run software applications is meant. Node JS is a runtime environment for the JavaScript language similar to how you would use a Python interpreter to run Python code on your computer. Node JS is being used to run and execute JavaScript code in the server to build backend services. Deploy Node.js applications on Hostinger’s VPS hosting for top-notch performance.

Difference between setImmediate() and process.nextTick() methods
Python isn’t an ideal platform to deal with real-time web applications. The fastest speed and great performance are largely due to Node.js being based on Chrome’s V8 which is a very fast and powerful engine. Python is slower than Node.js, As Node.js Software development is based on fast and powerful Chrome’s V8 engine, Node.js utilizes JavaScript interpreter.
