There are a few PaaSs such as nodejitsu and Heroku. Or you can indeed set up nodejs on a linux box i. Not relevant at all. Even bash could serve that many requests, on the slowest server. Scratch server. Slowest VM. The most important reasons to start your next project using Node All the coolest dudes are into it You can hangout at the cooler and have lots of Node adventures to brag about. You're a penny pincher when it comes to cloud hosting costs.
What to expect You'll feel safe and secure with Express without all the server bloatware you never needed. Runs like a rocket and scales well. You dream it. You installed it. The node package repo npmjs. Your brain will get time warped in the land of nested callbacks Sequelize and Passport are your new API friends. Debugging mostly async code will get umm Time for all Noders to master Typescript.
Who uses it? Yes I could have answered this question in the traditional way. I think I'm qualified to do so but most of it has already been said and I thought some light hearted fun would break the monotony. I regularly contribute technical answers on other questions.
CleanCrispCode: Yes indeed! I am just putting my thought on the same: When to use Node. JS If your server side code requires very few cpu cycles. If you are from Javascript back ground and comfortable in writing Single Threaded code just like client side JS. When NOT to use Node. Scalability Consideration with Node. JS Node. JS itself does not utilize all core of underlying system and it is single threaded by default, you have to write logic by your own to utilize multi core processor and make it multi threaded.
JS Alternatives There are other option to use in place of Node. Braiam 4, 11 11 gold badges 50 50 silver badges 73 73 bronze badges. Ajay Tiwari Ajay Tiwari 3, 1 1 gold badge 14 14 silver badges 13 13 bronze badges.
If my understanding is right, one of the strengths of the node. So Node. OndraPeterka: You are right that Node. It is non blocking IO only for incoming requests to server but not for outgoing request from your app request handler. This really boost up Node app performance at least twice. However, I think performance should be more than twice when they stablize cluster lib. You can use node. Use fork.
See stackoverflow. Node handles multiple cores very well with the cluster module. Show 1 more comment. BoxerBucks BoxerBucks 3, 2 2 gold badges 19 19 silver badges 25 25 bronze badges.
And these packages are all relatively fresh, so they have the benefit of hindsight and tend to conform to recent web standards. With all due respect, a lot of packages on npm are terrible, because npm doesn't have a mechanism to rate packages. Hindsight from CPAN anyone? I don't know about when you made the comment but as of right now the ws library supports that spec — Jonathan Gray. Edit Its been several years since I have started using nodejs and I have used it in making many different things including static file servers, simple analytics, chat apps and much more.
This is my take on when to use nodejs When to use When making system which put emphasis on concurrency and speed. Sockets only servers like chat apps, irc apps, etc. Social networks which put emphasis on realtime resources like geolocation, video stream, audio stream, etc. Handling small chunks of data really fast like an analytics webapp. As exposing a REST only api. When not to use Its a very versatile webserver so you can use it wherever you want but probably not these places.
Simple blogs and static sites. Just as a static file server. Simple blogs can still benefit from Node. For serving static files, you can still use Node. Apache httpd server is a dinosaur which is dying - see this Netcraft survey. I would say otherwise - take a look at ghost. Also, creating a simple page in NodeJs, say using sailsjs. Vinayak Bevinakatti Vinayak Bevinakatti So In traditional system what will happens : 1. Now here is , how node will do it: 3. So no waiting, no threading , no memory consumption — yes this is nodeway for serving rest API.

My one more reason to choose Node. Sean Zhao Sean Zhao 1, 11 11 silver badges 12 12 bronze badges. Actually Cloud9 IDE and the others koding the one i use support almost all kind of web language. Are you serious dude? Donning asbestos longjohns Let me include a few quotes that are relevant here: Warning: Node. The Appendix, which I did not really want after the rising crescendo in the last chapters and the conclusion, talks about what I was able to find in the ecosystem, and provided a workaround for moronic literalism: Another database that seemed like a perfect fit, and may yet be redeemable, is a server-side implementation of the HTML5 key-value store.

I leave it as an exercise to the reader, but it's enough to look at the so called solutions for flow control. That's not really an answer. You claim that the existing solutions are "terrible hacks", yet fail to point out any of them.
Have you considered that you might simply not understand or be aware of the correct methods for scaling Node. I updated my answer a little. Maybe you still have complaints, but if you think it is wrong you should comment with details That would be more productive for the community imo. For realtime applications like chat,collaborative editing better we go with nodejs as it is event base where fire event and data to clients from server.
Simple and easy to understand as it is javascript base where most of people have idea. Lot of plugins available. Drawbacks:- Node will support most of databases but best is mongodb which won't support complex joins and others. Compilation Errors Naeem Shaikh While you don't get compile-time checking, JSDoc allows you to add any type info you'd like so that things make more sense when you come back. Properly decomposed small functions are also typically quite easy to grok due to their well-defined environment the closure.
Bad stack traces can often be resolved with some re-factoring to ensure you aren't splitting your logic up with an asynchronous callback in between. Keeping your async callbacks within the same closure makes it easy to reason about and maintain. I have spent 30 years with compiled languages, but after using it for only about a year JavaScript is now my language of choice. But it's a different mindset. Un-typed variable are actually an advantage in many cases.
When you need to do things concurrently asynchronous callbacks are much safer, easier and ultimately more productive than any language where you have to use threads. And you have to know JavaScript anyway because its the language of the browser.
I do sympathize with the concerns raised, and I note that some efforts have been made to address them, although they are certainly not universally applied. There is an amazing project called Tern which can provide type derivation from static analysis of Javascript code and libraries.
It has plugins for various editors. And then there is Go , one of many compile-to-Javascript languages! The Overflow Blog. Does ES6 make JavaScript frameworks obsolete? You may be asking, what kind of apps can I make with Node. The answer is: Node. Below are some of the apps you can develop using Node. Looking at the rate at which Node.
