Is It Possible to Run Components Built Against Different Versions of Polymer on the Same Page?

[Walter Rumsby]

Hi,

As far as I can tell Polymer is a global object in the browser.

Let's say I have a page that pulls in multiple components. Say a couple from http://googlewebcomponents.github.io/ and say a couple I wrote myself. For whatever reason I can't Vulcanize all the components together (although I can Vulcanize the set from googlewebcomponents and the set I wrote myself).

Does this mean that both sets of components need to use the same Polymer version when running on a page? I'm worried that unless there is guaranteed backwards compatibility (which I assume can't be the case with a < 1.0.0 release) then running the most recent version of Polymer isn't guaranteed to work.

Thanks,

Walter

Yes, they will need to have compatible versions of Polymer to work together (to the best of my knowledge), just like jQuery plugins have to have a compatible version of jQuery to run properly.

This is going to be 100x more painful today than it will be once Polymer reaches 0.9/1.0 -- presumably at that point the API will be very stable and breaking changes will occur infrequently.
