What is Node.js
- It propels the tasks to the computer’s file system.
- Allows the system to wait until the file is opened and read.
- The content is sent easily to the Client.
- It then readies itself to take care of the upcoming requests.
But Node.js manages the file request differently, as follows:
- Node.js can hurl the task to computers file system.
- Node.js readies to get a hold of the subsequent request.
- The server returns the content instantly to the client after opening and reading the files.
It must be noted that Node.js completely diminishes the wait period and takes on the next requests. Its speed of operation has to be seen to be believed. Node.js runs as asynchronously programming, non-blocking, and single threaded, making it supremely memory efficient. Node.js files have the ability to execute different level of events at ease. Ideally, ones that try to look p for port access on the server. But Node.js files are required to be kicked off on the server. Node.js files have extensions ‘.js’. But there are several tasks that node.js can perform, and some of these are:
- Collection of form data.
- Perform all actions on the server – opening, creating, reading, writing, deleting and closing files.
- Addition, deletion, and modifying data in the database.
- Creating a dynamic page content.
How It Works
Some of the best features of Node.js are discussed below:
- Security: A Node.js core is fully secure. But a problem exists with installation of third-party packages. The way these are configured, installed and deployed may require additional security to protect web applications from the hacker.
- Node.js Vs PHP: Some programmers prefer PHP because it is easier to learn than Node.js, and features an integrated Database. But Node.js is far more extensive than PHP. Node.js is also blindingly faster compared to PHP, and these two features often make Node.js the first choice.
- Use: Node.js uses an event-driven, non-blocking I/O model, that make sit light-weight and efficient, perfect for Data-intensive, Real-time applications that run across distributed devices.
- Scalability: Node.js offers easy scalability.
- Performance: Node.js is known for high performance.
- Support: Node.js has the support of a large and active community.
- Node Package Manager (NPM): NPM is the root of almost all deployment systems for Node.js, and underlies the many PaaS (Platform-as-a-Service) providers for Node.js. Its simple and dependable package management has supported the Node Ecosystem grow spectacularly in recent history.
The Future of Node.js
Node.js has the fastest runtime among all programming languages, thanks to the dominant language and also the support and assistance by the major browsers. The future appears to be challenging and strikingly brilliant for Node.js in the front-end world, as it seems like no front-end improvement is possible without Node.js. Development with Node.js lives up to its high reputation as the new standard for Enterprise Applications. Some experts and top drawer developers are even beginning to claim that it is so powerful, that it has the potential to replace Java for good. This would dethrone Java as the most trusted language, which is a spot that Java has held since 1995. For example, recently PayPal transferred all apps from Java to Node.js, for which the main reason is the ability of Node.js to iterate rapidly.
