An equally important challenge in a growing business is scaling your development team. Most technology companies hit a wall with dev team scalability somewhere around ten developers. Having navigated this process fairly successfully over the last few years at Heroku, this post will present what I see as the stages of life in a development team, and the problems and potential solutions at each stage. Stage 1: Homebrewing In the beginning, your company is 2 - 4 guys/gals working in someone’s living room, a cafe, or a coworking space. At this stage, you’re trying to create and vet your minimum viable product, which is a fancy way of saying that you’re trying to figure out what you’re even doing here.

As Node.js continues to rise in popularity and the number of modules on npm rapidly increase it becomes harder and harder to keep up with the useful and unique modules.
So in order to make it a little easier I've compiled a list of some of the great Modules you might not know about. 1. Passport Passport is a simple way to add authentication to your application.

Lorch IIILeave a Comment Percona XtraBackup 2.1 has been in GA now for a little over four months and has some impressive new features to improve backup performance, security, and storage requirements. When used with Percona Server, additional features are enabled that can provide even more dramatic performance improvements. Percona XtraBackup is open source, free MySQL hot backup software that performs non-blocking backups for InnoDB and XtraDB databases. Vagrant. The Hosebird Client streaming library. Apache Thrift.

Omissis/psr-http. Building a Decent API. PHP developers are increasingly moving over to API development, as are a lot of server-side developers.
It's a trend thats been happening for the last few years and it's getting to the point where everyone and their dog are putting articles showing off how to build "awesome" API's. Unfortunately most of these are either woefully inadequate or are promoting bad practices. I'm not going to link to any bad examples because that's just rude, but here are some golden rules that I stick to when building out API's. Never Expose DB Results Directly If you rename a field, then your users are fucked. Use the URI sparingly, and correctly Use the query string for paired params instead of /users/id/5/active/true. Resources are EVERYTHING You're always either asking for one resource, or multiple.
JSON, XML or shut up Don't spend forever trying to make your system output everything under the sun. Authentication OAuth 2 is the shit. Goodbye node-forever, hello PM2. It’s no secret that the devo.ps team has a crush on Javascript; node.js in the backend, AngularJS for our clients, there isn’t much of our stack that isn’t at least in part built with it.
Our approach of building static clients and RESTful JSON APIs means that we run a lot of node.js and I must admit that, despite all of it awesomeness, node.js still is a bit of a headache when it comes to running in production. Tooling and best practices (think monitoring, logging, error traces…) are still lacking when compared to some of the more established languages. So far, we had been relying on the pretty nifty node-forever. Great tool, but a few things were missing: Limited monitoring and logging abilities, Poor support for process management configuration, No support for clusterization, Aging codebase (which meant frequent failures when upgrading Node). This is what led us to write PM2 in the past couple months. So what’s in the box? First things first, you can install it with npm: Scalability, Availability & Stability Patterns. Open Source ETL designed to bridge the gap between business and IT. Erlang on Xen - at the heart of super-elastic clouds.
