Node.js. Node.js and MongoDB. Static Version This was the sixth in a series of posts leading up to Node.js Knockout on how to use node.js. This post was written by 10gen and is cross-posted from their blog. 10gen is the corporate sponsor of MongoDB. MongoDB bridges the gap between key-value stores (which are fast and highly scalable) and traditional RDBMS systems (which provide rich queries and deep functionality). Node and MongoDB Node.js is turning out to be a framework of choice for building real-time applications of all kinds, from analytics systems to chat servers to location-based tracking services.
The rationale is certainly there. Node.js MongodB Driver Especially impressive to us at 10gen has been the community support for Node.js and MongoDB. Hummingbird Need a real-world example? Mongoose Of course, one of the admitted difficulties in working with Node.js is dealing with deep callback structures. View the discussion thread. Node.JS. You use Node.js to write event-driven, scalable network programs in server-side JavaScript. Node.js runs on Google’s V8. This section describes the available tools and suggested practices for using Node.js with MongoDB. For a more detailed discussion, see the Node.js Driver Manual. The following are the README and source code: Node.js Driver The MongoDB Node.js driver is the officially supported node.js driver for MongoDB.
Install or Upgrade The easiest way to install is to use npm: Object Mappers Because MongoDB is so easy to use, the basic Node.js driver can be the best solution for many applications. Other Notable Projects Mongoskin: Layer for node-mongodb-native.Mongolia: Lightweight MongoDB ORM/driver wrapper.Mongojs: Somewhat mimics the MongoDB shell api. Each of these projects build on top of the native Node.js driver, and so some knowledge of that is useful, especially if you work with a custom MongoDB configuration. 3rd Party Drivers A few 3rd party drivers exist. Getting Started with Node.js on Windows. UPDATE: New packages and further items What a difference a year makes.
Last year at the first conference solely dedicated to JavaScript, JSConf 2009, there was a big focus on the uses of JavaScript on the client side. This year, there was a marked change with server-side JavaScript taking up about half the sessions at JSConf 2010 this past April. The rise of server-side JavaScript has been in large part to two platforms, Narwahl and node.js. Why Node? In this series, I’m going to focus a little bit on getting started on node.js and how you can mix the Reactive Extensions for JavaScript into your node solutions.
Getting Started One downside has been in the past for me, being a developer who uses Windows frequently (given that I’m employed by Microsoft), has been the lack of native support for Windows. When installing Cygwin, I chose the following packages: Once that installs, before you’ll be able to successfully build anything, you should do a rebaseall by doing the following steps: Why Developers Should Pay Attention to Node.js. There's a substantial amount of buzz and enthusiasm right now about Node.js. So what is it, and why should you care about it (well, other than "I said so")? ReadWriteWeb chatted with Javascript developer Guillermo Rauch, co-founder and CTO of LearnBoost in order to get some insights. ReadWriteWeb: So, what is Node.js? ReadWriteWeb: Why should developers care? Rauch: First of all, most web developers are already using jQuery, MooTools, or similar frameworks to leverage JavaScript on the browser.
That means they'll be instantly familiar with Node.js, even though it's a different environment with unique idioms and constructs. Secondly, thanks to the expressiveness of JavaScript and the concise yet powerful Node.js API, you can build programs that have been typically considered out of reach or too time consuming. And lastly, you won't be alone. ReadWriteWeb: What are the key benefits of Node.js? Rauch: There are several: Fast. Rauch: It's incomplete. This is the only problem I see right now. Introduction to Nodejs (taking javascript to the server-side) - GeexHQ.
0inShare Web Technologies so far Remeber those days when we used only the basic features of html to bring texts, images, tables and few other layouts into our webpage, Later CSS came into the picture and created a huge impact or it has actually influenced the way a normal web user-interface is made. After creating webpages & designs using markups and CSS, developers turned their focus onto the data transfer techniques, thats when Ajax came into the picture. Ajax is one among the awesome web technologies that has taken the web user experience to another level, these days we do a lot of work on the web in less time and without actually reloading a full page.
And then we have javascripts on the client side for creating all the user interactions along with ajax & more other technologies Taking Javascript to the server-side However, Node.js is a bit different from these solutions, because it is event-based rather than thread based. Featuring “nodeJs†p>To exit hit “ctrl + c†p> Node.js. Node.js. Node.js is an open source, cross-platform runtime environment for server-side and networking applications.
Node.js applications are written in JavaScript, and can be run within the Node.js runtime on OS X, Microsoft Windows, Linux, FreeBSD, NonStop and IBM i. Node.js provides an event-driven architecture and a non-blocking I/O API that optimizes an application's throughput and scalability. These technologies are commonly used for real-time web applications. Node.js is gaining adoption as a server-side platform[4] and is used by Microsoft,[5][6] Yahoo! History[edit] Ryan Dahl, creator of Node.js Node.js was invented in 2009 by Ryan Dahl, and other developers working at Joyent.[17] Node.js was created and first published for Linux use in 2009.
Dahl was inspired to create Node.js after seeing a file upload progress bar on Flickr. In June 2011, Microsoft partnered with Joyent to implement a native Windows version of Node.js.[23] The first Node.js build to support Windows was released in July. Why You Should Pay Attention to Node.Js ? tecosystems. Learning Server-Side JavaScript with Node.js. Meet Node.js | PeepCode Screencasts for Web Developers and Alpha Geeks. Preview Download Free Preview NOTE: The code download has been updated for the latest Node 0.6.10 release and NPM 1.1.1. The Web has seen at least four major advancements in browser technology, about once every five years. Ajax has been around for five years, and we’re at the next jump: persistent connections between server and client. Node.js makes it easy to write asynchronous, event-driven applications that serve static, dynamic, and persistent data to clients while using a minimum amount of RAM and CPU time.

If you’ve been paying attention to news about web technology in the last year, you’ve most likely heard the name node.js mentioned at least once or twice.
What happened next probably went like this: you asked, “What is it?” And someone (or Google) told you that it was a way to write web servers using JavaScript. If that didn’t scare you away, you might then have asked, “Why would you want to use it?” And the answer might have been along the lines of it taking advantage of non-blocking, event-driven IO to enable high concurrency in long polling or comet-based applications.
At which point you stopped asking questions. I don’t blame you. To help break apart that wall of jargon, here’s my attempt at explaining what node.js is and why you should be paying attention to it. So here’s how it is, how it’s always been: a browser sends a request to a website. Then there was Ajax. Now think about what that means for a traditional web server like Apache. So what’s the solution? Virtual Panel: The Node.js Ecosystem - Frameworks, Libraries and Best Practices. Node.JS and the WebSocket protocol. After reading Simon Willison’s post on Node.JS, I decided I’d give it a try myself.
Today I released node.websocket.js After a couple of months I’ve been watching the progress on the WebSocket protocol, which gives JavaScript developers full-duplex communications channels in the browser. This is a very exciting alternative to the COMET techniques we’re used to seeing. Node.JS is a framework for networked, event-driven applications, where JavaScript has a natural fit. This particular implementation is built on top of the excellent V8 engine. Running the server is as simple as: Logging (in the Redis storage, an excellent persistent key-value storage mechanism which will be subject of another post) will begin. Var a = new WebSocket();a.onmessage = function(event){ console.log(event.data);}; As you might know or induce already, the wonder of WebSocket is only available to a few selected browsers.
Twisted. Twisted is an event-driven networking engine written in Python and licensed under the open source MIT license. Twisted runs on Python 2 and an ever growing subset also works with Python 3. Twisted makes it easy to implement custom network applications. Here's a TCP server that echoes back everything that's written to it: from twisted.internet import protocol, reactor, endpoints class Echo(protocol.Protocol): def dataReceived(self, data): self.transport.write(data) class EchoFactory(protocol.Factory): def buildProtocol(self, addr): return Echo() endpoints.serverFromString(reactor, "tcp:1234").listen(EchoFactory()) reactor.run() Learn more about writing servers, writing clients and the core networking libraries , including support for SSL, UDP, scheduled events, unit testing infrastructure, and much more.
