In part one, Alex Gorbatchev pulled out the non-breaking API changes, while in part two he separated out breaking APIs. In part three, Be
You are here: Home / StrongBlog / Community / The Node v0.12 Release Branch is Here – What’s Going On? Yesterday tjfontaine created the Node v0.12 release branch. Does that mean a release is imminent? TJ is in charge of when the release hits, so we don’t know precisely, but here’s our take: not so fast. This is just the release branch to work from. The release may be a while still. We sponsor 5 of
New Features Coming to Node v0.12 Node v0.12 has been in development for over a year and along with the community, StrongLoop is excited for it to become generally available. We’ve compiled a list of what’s new in the upcoming release and how to make use of these new features. Cluster round-robin load balancing Performance optimizations Running multiple instances in a single process execSync: a sy

Node.js Performance Tip of the Week: Managing Garbage Collection by Shubhra Kar Jun 25, 2014 / Community, How-To, Please note that as of Aug 3, 2015, StrongOps has been EOL’d. In our last weekly performance tip, we discussed in detail how the Node.js event-loop works as the orchestrator of requests, events and callbacks. We also troubleshot a blocked event-loop which could wreck havoc on applicati
Comparing Winston and Bunyan Node.js Logging by Alex Gorbatchev Jun 24, 2014 / Community, How-To, Resources Lets talk about logging, shall we? Arnold over here carrying a giant log feels like an appropriate intro to this article in which we are going to talk about popular Node.js logging frameworks. If you are writing any kind of long living application, detailed logging is paramount to spotting p

Node.js Performance Tip of the Week: Scaling with Proxies and Clusters by Shubhra Kar May 16, 2014 / Community, How-To, Please note that as of Aug 3, 2015, StrongOps has been EOL’d. In last week’s performance tip, we discussed in detail how to diagnose application performance bottlenecks using CPU profiling on Node.js applications. In this go around we look at scaling Node.js applications in produ
Generators have been all the rage lately. Many Node developers (including myself!) are excited and intrigued about writing their asynchronous code like this: However, this is just one use case (although a clever one) of using generators. In this article, we will explore the strengths of using generators. There is a GitHub repository with the code samples we will go through that you can check out.
You are here: Home / StrongBlog / How-To / Node.js Performance Tip of the Week: Memory Leak Diagnosis In last week’s performance tip, we discussed in detail how to leverage Google V8′s heap profiler to diagnose problems with Node applications. In this go around we look at different leak patterns and how a good diagnosis can lead us to find the root cause of a potentially troublesome production pro
Comparing Node.js Promises, Try/Catch, Angular Zone.js and yes, Zone by Alex Gorbatchev Apr 15, 2014 / Community, How-To Handling errors in asynchronous flow In a previous article we talked about managing async flow and escaping the callback hell. The problem Handling errors in synchronous flow is pretty straightforward and easy. Handling errors in asynchronous flow in a clean and easy to follow m
Beyond Node.js Express: An Intro to Koa.js and a Preview of Zones by Jed Wood Apr 11, 2014 / Community, How-To, LoopBack In late 2013, the team behind Express.js announced a new framework called Koa. It uses some features that require an unstable dev version of Node, but in this post I’ll show you how easy it is give it a try both locally and on Heroku. Before We Start Whether you play it safe and

You are here: Home / StrongBlog / Community / What’s New in Node.js v0.12 – Running Multiple Instances in... An oft-requested feature is the ability to embed Node.js in other applications, particularly in ways that let it integrate with other event loops and (“while you’re at it”) with support for multiple Node execution contexts: that is, the ability to have multiple instances of Node co-exist pe
doAsync1(function () { doAsync2(function () { doAsync3(function () { doAsync4(function () { }) }) }) Callback hell is subjective, as heavily nested code can be perfectly fine sometimes. Asynchronous code is hellish when it becomes overly complex to manage the flow. A good question to see how much “hell” you are in is: how much refactoring pain would I endure if doAsync2 happened before doAsync1? T
What Makes Node.js Faster Than Java? by Issac Roth Jan 30, 2014 / Community Every few weeks someone posts a Java vs Node benchmark, like PayPal’s or Joey Whelan’s. As one of maintainers of Node core and contributors to many npm modules, StrongLoop is happy to see Node winning lately. Everyone knows benchmarks are a specific measurement and don’t account for all cases. Sometimes Java is faster. Som

Creating Desktop Applications With node-webkit by Mike Cantelon Nov 26, 2013 / How-To Editor’s Note: As some of you may know, the node-webkit project was rebranded “nw.js” because they are now using io.js and Chromium. This article was written long before that change. We’re working on a new article with updates examples for you, but much of the content below still applies! [Sputnik:](http://sputni
A Brief History of JavaScript Bridges in Mobile In 2009 Appcelerator’s Titanium 0.8 Version changed from a ‘Hybrid web container’ based approach similar to Phone Gap / Cordova to full ‘Native binding’. The change required Titanium developers to re-architect their code and remove HTML as the top-level implementation. Developers wrote their apps in pure JavaScript. The value to developers and Appcel

How-to: Heap Snapshots and Handling Node.js Memory Leaks by Marc Harter Oct 2, 2013 / How-To _In the beginning, there were memory leaks in JavaScript … and we could not have cared less._ _Then there was Ajax … and we started to care._ _Then there were these long-running Node processes on our production servers … and we really cared a lot!_ Node memory leaks happen. Usually they occur in production
