Polymer应用程序Firebase托管部署不起作用

Question

I have created a Polymer app using the starter kit from the yeoman generator as a starting point. The app works fine locally. After doing a full build, I did a firebase init, and a firebase deploy. I get no errors, however, when I launch the app URL, I get what looks like vulcanized JavaScript displayed in chrome.

I am not sure what is wrong. No errors reported.

Thanks

I've had a similar problem. After running vulcanize the page would only show JavaScript instead of the actual page content. Started like:

'),t=""+t+"";try{this.Ea.eb.open(),this.Ea.eb.write(t),this.Ea.eb.close()}catch(o){Cb("frame writing exception")...

There was also a syntax error in the index.bundle.js, which might have caused the problem.

Uncaught SyntaxError: Unexpected token ILLEGAL -> index.build.js:13 Uncaught SyntaxError: Unexpected token ILLEGAL

I couldn't get the project to run in vulcanized state afterwards. Solved the problem by creating a new poylmer starter kit project. Worked like a charm after I copied my files into the fresh directory. Hope this might help you.

The problem comes from Firebase library when you "vulcanize" your elements.

You have to exclude it from your vulcanize task (in gulpfile.js)
