Is Node JS good for large applications?
It is suitable for large enterprise projects that do complex and complicated computations and data processing. The comparison in terms of development time between Node. js and Java is that, Node. js is easier to learn than Java, leading to faster development when using Node.
HEAVY SERVER-SIDE COMPUTATION/PROCESSING
When it comes to heavy computation, Node. js is not the best platform around.
This unique architecture of NodeJS helps developers manage multiple connections simultaneously. So it's wise to use NodeJS for enterprise apps because of its ability to handle a large number of connection requests efficiently.
The asynchronous feature is what makes the single-thread of the Node. js program quite efficient. It makes the program fast and scalable without using as many resources as a multi-threaded application. Naturally, this makes Node a good fit for data-intensive and I/O intensive programs.
Not Suitable for Heavy-Computing Apps
Node. js doesn't support multi-threaded programming yet. It is able to serve way more complicated applications than Ruby, but it's not suitable for performing long-running calculations. Heavy computations block the incoming requests, which can lead to decrease of performance .
js receives a CPU bound task: Whenever a heavy request comes to the event loop, Node. js would set all the CPU available to process it first, and then answer other requests queued. That results in slow processing and overall delay in the event loop, which is why Node. js is not recommended for heavy computation.
js is single-threaded, CPU-intensive tasks will block all requests from completing, until the task is completed. Therefore Node. js isn't a good solution for CPU-intense tasks".
Java is heavily used for building complex web-based application with an already provided framework built using Java, whereas Node JS is best suited for real-time collaborative drawing or editing applications like Google Docs.
First, Node js is fast and powerful, and therefore capable of handling large data flows. Second, you can easily integrate Node. js with IoT protocols (the integration with MQTT and WebSockets can be a good example).
NodeJS has evolved as the most leading enterprise-ready technology for building sophisticated applications.
Is PHP better than NodeJS?
Due to the V8 engine, asynchronous execution, and real-time server interaction, Node. js offers a better execution speed and certainly outperforms PHP.
If you are looking for real-time web apps, then Node. js might be the best choice for Back-end development as it has all the above features which is very great in delivering excellent performance. It is built on a single-threaded, non-blocking event loop, Google V8 engine and low-level API.
Flash forward to today and Google is a Platinum member of the Node. js Foundation and has a board seat filled by Sarah Novotny, Head of Open Source Strategy, GCP, Google. Google has built a tighter relationship between the Node. js and the V8 JavaScript Engine (V8) communities and has several employees on the Node.
Node.js offers Easy Scalability
With Node. js, you'll have no problems scaling the application horizontally across multiple servers or vertically to increase its performance on a single server.
However, Facebook is using Node for a few things. One is JSGameBench, an HTML5 game benchmarker. Another is a mobile JS framework that has yet to be announced, but will probably be open-sourced.
Ask HN: Why is Node. js hated so much? Probably the worst thing is that the standard library with Node Javascript is tiny. Therefore, you have to pull in a pile of NPM packages to do pretty much anything.
Yes of course they do. Unhandled exceptions (remember that exceptions are exceptional) crash and burn the server. This is why in production we have strong guards against this. We use clusters of nodes that restart any instances of your application if one crashes.
You can achieve multithreading by generating multiple nodes or Node. js V8 engines which in isolation are single-threaded. It is still correct to say Node. js is not multi-threaded.
It runs on one CPU core regardless of how many CPU cores you have in your machine or a virtual machine in the cloud.
No, the answer doesn't have to be multi-threaded.
Why do I need node JS?
js programmers claim to use Node. js for enterprise apps. It's a light, scalable and open-source language platform which makes it very easy to build apps even at the enterprise level also. Overall it increases the efficiency of the development process as it fills the gap between frontend and backend applications.
Node. js is a great choice for developers in 2022, especially due to the infancy of non-blockchain decentralized web frameworks in JavaScript that offer comparably pureness against attack vectors and availability of scaling solutions like peer-to-peer web servers.
Yes, Node. js can run server-side and make connections to databases, as well as serve content via endpoints, if that's what you wish. You can look into Express for an implementation of server technology. Whether or not Node would be capable of replacing Java for your use-case would depend on your actual use-case.
For example, you can develop an application in Java and link to it with JavaScript through an engine like Rhinorun. However, in a real-world scenario, picking Node. js for your web application makes more sense. It's just faster and more scalable than Java, when it comes to web apps.
No, the answer doesn't have to be multi-threaded.
A backend system for an automated vehicle that runs machine-learning algorithms to provide driving instructions to the vehicle in real-time is a CPU intensive application.
libuv is a multi-platform C library that provides support for asynchronous I/O based on event loops. It supports epoll(4) , kqueue(2) , Windows IOCP, and Solaris event ports. It is primarily designed for use in Node. js but it is also used by other software projects.
Node. js Global Objects are the objects that are available in all modules. Global Objects are built-in objects that are part of the JavaScript and can be used directly in the application without importing any particular module.
