Add scrollTo helper

[nlfurniss]

Inspired by the scrollTo helper from ember-native-dom-helpers.

If people are receptive to this, I'll add some tests :)

Looks good generally, tests and some more docs (thinking some examples) seem like a good next step...

[rwjblue]

Updates look good, I think we need a few more tests for the various error conditions that we throw for.

[rwjblue]

I think I've gotten CI fixed on master now, mind rebasing?

[nlfurniss]

Investigating why this is failing in Ember 2.0 for Cannot read property 'buildInstance' of undefined

I'd love to see this ported!

[nlfurniss]

Removed scrolling of window/document, added tests for error states

Looks like a downstream package has dropped support for Node 6 without bumping major versions (therefore breaking CI for us when using "floating dependencies"). I reported the issue over in socketio/engine.io#589, but I'm not sure yet if they will fix the issue.

If it does not look like they intend to resolve that issue in a day or so, I'll mark the floating dependencies CI run as an allowed failure so that we are unblocked.

[nlfurniss]

@rwjblue seems like this issue in socketio isn't getting fixed, would it be possible to allow this failure?

[rwjblue]

@nlfurniss - We have dropped support for Node 8 and lower now, I think this will pass with a rebase...

[rwjblue]

Rerolled yarn.lock in #814 and restarted the build here to try to fix those TS issues.

[nlfurniss]

passes 🎉

[rwjblue]

Thank you @nlfurniss!

Is this missing from API.md?

[nlfurniss]

@amk221 yes it is, I'll create an issue to add it once this code is published in a non-beta version

ah ok, just spotted randomly. 👍
