Detect Polymer compatibility

[Martin Kleinschrodt]

So there's this Polymer-based app I've been working on and I'm frighteningly close to releasing it to the public. Now I'd like to tell anyone who is using a browser that is not supported by Polymer to go to hell. Or to go get a decent browser - I haven't decided yet. Anyway, is there a reliable way to detect if a browser is supported by Polymer? I'm guessing this could be done relatively easily with feature detection if one knew the exact set of features that is required for Polymer to function properly. Are you perhaps maintaining a list of these features? Or is there even something like a js snippet somewhere? That would be tremendously useful.

Thanks!
Martin

According to Polymer's browser support matrix these are the set of features:

• MutationObserver
• HTML Imports
• Custom Elements
• Shadow DOM
• MDV
• Pointer Events
• Pointer Gestures
• Web Animations

Thanks, I didn't see that. Ironically the table is not showing in Chrome 32 on my Mac. Maybe I wasn't being clear enough, though. What I mean is: What features does the browser have to support for the polyfills to work? After all, almost none of the features listed on the compatibility page are natively implemented by any of the browsers yet. The page clearly states which browsers are supported by the polyfills but detecting the exact type and version of a browser is messy and I'd much rather rely on feature detection.

Also, this page is usually useful too to see what browsers and platform we run our unit tests on.

but it is broken at the moment.
