blitz.io, powered by Mu Dynamics, is a self-service load and performance testing platform. Built for API, cloud, web and mobile application developers, blitz.io quickly and inexpensively helps you ensure performance and scalabilty. And we make this super fun.Why Load Test?
Node.js is purdy fast, but if you are not careful in the way you invoke backend services like CouchDB or MongoDB, you can easily cause pipeline stall making your app not scale to a large number of users. Typically you will end up with each concurrent request taking longer and longer resulting in timeouts and fail whales. Load testing shows you what kind of concurrency you can achieve with your app and how it’s actually scaling out.Signing up

If your app is at
http://my.cool.app, the following blitz line will
generate concurrent hits against your app:
--pattern 1-250:60 --region virginia http://my.cool.app
As simple as that. If your
connect routes have
parameters in them that you use for looking up in your favorite
database, you can read up on variables
to parameterize query arguments and route paths so you can simulate
production workloads on your app.
At the start of the event, we are providing all contestants with enough blitz-power so you can generate lots of hits against your cool node.js app for 48 hours. We are also working on a scoreboard so you get bragging rights on the app with the most number of hits. Watch this page at the start of the event and you’ll know what to do.
For those developers that don’t like UI and prefer command line, here’s
the simplest way to run iterative load tests right after you
your changes to the app:
$ gem install blitz $ blitz api:init $ blitz curl --pattern 1-250:60 --region virginia http://my.cool.app
To build cool node.js apps is awesome, to watch it scale out? priceless!
