    Bro, WEBrick isn’t very good in production. It’s just not webscale. Let me know if you need help deploying with something else.

    We’re holding an event in Philly (Hack and Hops) in November featuring talks about node projects and why to use node.js over other languages. Any thoughts about Groupon’s possible participation in speaking and in particular about this switch?

    Great to see node working so well for you.

    Do you still using Rails in backend SOA services o replaced it completly with Node.js services?

    Some graphics or your architecture might be cool :)

      We’ll be following up with lots more information over the next month or so. Can’t wait to share it with everybody!

    Nice dood! I <3 node and I am happy to see this great report. I do also love ruby though and I think that it can be scaled.

    Does anyone else find this fascinating that Ruby on Rails was compared to an SOA architecture? Are those really apples to apples?

      Sorry, i didn’t mean it that way.

      We had an architecture problem primarily: Our Ruby on Rails app became a difficult to manage monolith. We use Ruby on Rails for many of our backend services. More to come soon.

    a good choice. node.js is cool

    good news, it’s about time to say goodbye to RoR

    This is awesome! Would love to read about how the transition went. Node FTW!

    “…and we will be blogging stories about this intense transition.”

    next time when you are starting a new website will you still use RoR as your first choice?

    thank you.

    So you had an app that lacked structure, and now it seems like you have an app with a better structure. The fact that these 2 use different languages is wrongfully highlighted in this post.

      I’m also confused by Sean’s post. Everything that was lacking with Groupon’s site could have been solved by using distributed Ruby server apps, and didn’t require a complete rewrite. There must be other issues that led to this decision, which I happen to be very interested in reading about. I am a fan of node.js and I’m trying to figure out how it makes companies more money.

        We could have easily used Ruby to solve this problem, but we went with Node after some consideration. Keep your eyes peeled for a followup post with more details about why we chose Node.js.

  15. October 11, 2013 @11:35 pm

    Can you post some numbers about your transition? How many servers cuts, which packages did you choose? A little about your stack and architecture? That would be great

      We’re working on follow up posts with this kind of detail soon.

    We ( moved to the same web-app-as-API-client approach earlier this year, and are slowly transitioning away from monolithic Rails backend to a collection of services. Its definitely the way to go, I think. The ‘single contract’ thing is really great – felt good when all we had to do to add a new section to our mobile app was deliver the API docs for the endpoints to our mobile app developers and sit back :)

    I think another benefit of SOA is the ‘horses for courses’ thing, whereby you can pick the best technology stack for each service – we have a Geo service built on top of PostGIS, and a messaging system built on MongoDB.

    Interesting times ahead :)

    Hey man you always says follow up post where is follow up post about this transition. Eagerly waiting…………….

    The first followup post is now live at:

    Great work!
