I want to make Hello, world with the Polymer firebase-collection element.
I expect to see one or more repetitions of Hello, world and no errors in the console. Instead, I see no Hello, world and many console errors beginning with:
ReferenceError: Firebase is not defined
To recreate the problem, follow these steps:
- Open this jsBin.
- ❌ Observe no Hello, world and errors in the console.
Notice the <firebase-collection> code is simply a copy/paste from the official documentation located here.
