Yeah, so we use GitHub, and we basically use a variant of continuous deployment where when anyone merges in a feature that they’ve finished with, they ship it immediately, and we bundle it up as a build pack and send it to all of our EC2 servers... Any developer on the team can trigger a build and deploy at any time. So on a given day, we probably deploy 20 or 30 times to prod. GitHub

We use it for a few things. We use it internally for a few dashboards because it’s actually really nice to have real-time dashboard data with Firebase. We also use it extensively for live order updating. For example, when a shopper is picking your items, you'll be able to go on your order screen. There will be live showing like found or not found or whatever. You'll have live position updating of your shopper on the map. You will have live information of the status of the order like “Nicole is now picking up your order,” and all these kind of things, so you don’t have to reload the page or pull or anything. Just live updates happen natively through Firebase API, which is nice. Firebase

Before two weeks ago or so, it used to be Backbone views and models, and everything was on our main store app, and our mobile web app, but actually, we just switched our mobile web app to using ReactJS for the interface. So it’s using Backbone models but ReactJS front-end components. Really, it was borne out of the frustration with how the Backbone model-view bindings worked, and it wasn’t especially performant for large views, and we had to do lots of tricks to make it performant. But swapping that out with React views meant that it could be both simpler and faster without having to spend a lot of time on that.

One other interesting thing about that is, since React actually works okay with the Backbone models and the Backbone router and stuff like that, we didn’t have to rewrite the mobile web application and update it to ReactJS. Rewrites are almost always a bad idea. We were able to upgrade pieces of it at a time, move on to React, and now the entire thing is using React and just has the Backbone router and models and stuff like that that we already had, so it's a lot faster.

So we very, very early on, we were iOS only, then we thought, well we’re missing out on half of the market. We need to add Android. So we had a friend of ours start working on the Android app, and I had to build the API for him, but I was having a really hard time doing that because I didn’t know what he needed exactly, so I built the first version of the web store over the weekend because I wanted to have a client to consume myself for the API I was building.
