FWIW, Trello didn’t launch with an API. It’s something we added in the first few months after launch. Just about everything goes through the API now since the mobile apps also use it, so you could say it’s an API first design NOW.

It’s true that Trello never supported IE8, but we never promised or intended to add IE8 support. We wanted to support the browsers of today and tomorrow, which was IE9 at launch.

That rarely happens in our experience. With our internal board, we know who is working on what and in what area of the code. Plus, all code is reviewed by someone working in the same area.

Everyone runs dev environments locally and tests. A dev environment is really easy to set up with mongo and node. Occasionally, we’ll put stuff on a staging environment if we want to test a database or infrastructure change. Big, experimental client changes go to the alpha channel on production.

It was a joke. =)

er, by stable branch, i mean stable _channel_. or whatever channel.

When it's nobody's job, nobody does it. Any developer COULD do it, though.

If there are necessary API changes, we just need to push updates to the API ahead of time. The API needs to be stable and backwards compatible anyway for the mobile apps (and all third party apps).

Right. The there is only one version of the API. Multiple clients.

I hope Doug writes a more technical post about the multi-client build/release process. We have unit tests for the whole API and very few automated tests for the front-end. Client builds are stored in S3. We use mongoDB and will do backfills if necessary (pretty rare). Rolling back the client is just pointing the stable branch to another build.

Yes, this was in perceived rendering time, and yes, the trade-off was worth it. We kept the async rendering stuff localized so it doesn't complicate the app much.

Trello does not support IE8. That line is not in production. I just wanted to show you how to add support if you needed it.

It's true that self-closing, non-void elements are not valid. With gzip, it's probably not even worth the savings in size. I know it's bad and we shouldn't do it and it will probably blow up in our face one day, but it doesn't seem to matter in practice and I just like the way it looks.
