Polymer 1.x application doesn't work with Chrome v80

[andriyaucar]

Description

I have Angular 5.x project. It works fine with Chrome 79. But after Chrome 80 version update, lots of errors occured. I did instructions in https://developers.google.com/web/updates/2019/07/web-components-time-to-upgrade but it still doesn't work. Do you have any comment or recommendation?

Browsers Affected

• Chrome
• Firefox
• Edge
• Safari 11
• Safari 10
• IE 11

Versions

• Polymer: v1.9.1
• webcomponents: v0.7.24

And I used

<script src="bower_components/webcomponentsjs/webcomponents-lite.js"></script>
<script>
  window.Polymer = {
    dom: 'shadow',
    lazyRegister: true,
    useNativeCSSProperties: true
  };
</script>

Hello, andryaucar... put the polyfills and if you use Raven.js - Sentry SDK for JavaScript use a condicional to test raven is loaded.. for me works!!!

[andriyaucar]

My project have polyfills.ts as below;

import 'core-js/es6/object';
import 'core-js/es6/string';
import 'core-js/es6/array';
import 'core-js/es7/reflect';
import 'zone.js/dist/zone';

And I don't use Raven.js.

The problem still continues.

@andriyaucar what errors are you seeing? And is there an application URL you can share, or is this an internal app?

[andriyaucar]

I see below errors on console;

zone.js:2969 GET http://localhost:xx/bower_components/iron-dropdown/iron-dropdown.html 404 (Not Found)
zone.js:2969 GET http://localhost:xx/bower_components/iron-ajax/iron-ajax.html 404 (Not Found)
zone.js:2969 GET http://localhost:xx/bower_components/promise-polyfill/promise-polyfill-lite.html 404 (Not Found)

Yes it is internal app.

And I see below warnings as well;

HTML Imports is deprecated and has now been removed as of M80. See https://www.chromestatus.com/features/5144752345317376 and https://developers.google.com/web/updates/2019/07/web-components-time-to-upgrade for more details.

hi @andriyaucar, my Polymer projects are using this soluctions:

    <script src="bower_components/webcomponentsjs/webcomponents-lite.min.js"></script>
    <script src="bower_components/webcomponentsjs/CustomElements.min.js"></script>
    <script src="bower_components/webcomponentsjs/HTMLImports.min.js"></script>

and

<script>
      // Setup Polymer options
      window.Polymer = {
        lazyRegister: true,
        passiveTouchGestures: true
      };

      // Load webcomponentsjs polyfill if browser does not support native Web Components
      (function() {
        'use strict';

        var onload = function() {
          // For native Imports, manually fire WebComponentsReady so user code
          // can use the same code path for native and polyfill'd imports.
          if (!window.HTMLImports) {
            document.dispatchEvent(
              new CustomEvent('WebComponentsReady', {bubbles: true})
            );
          }
        };

        var webComponentsSupported = (
          'registerElement' in document
          && 'import' in document.createElement('link')
          && 'content' in document.createElement('template')
        );

        if (!webComponentsSupported) {
          var script = document.createElement('script');
          script.async = true;
          script.src = '/bower_components/webcomponentsjs/webcomponents-lite.min.js';
          script.onload = onload;
          document.head.appendChild(script);
        } else {
          onload();
        }
      })();

      // Workaround due to an issue on older versions of IE11 running on W10
      if (!window.location.origin) {
        window.location.origin = window.location.protocol + '//' + window.location.hostname + (window.location.port ? ':' + window.location.port: '');
      }
    </script>

and my bower.json has this dependencie

{
"webcomponentsjs": "^0.7.24"
}

I am also having the same issue with an internal app.

The application is build on Angular 1.5

As per the site
"https://www.polymer-project.org/blog/2018-10-02-webcomponents-v0-deprecations"
I have added in the following for loading polyfills

<script src="/bower_components/webcomponentsjs/webcomponents-lite.min.js"></script>

but adding or removing this script does not have any effect on the UI.

Kindly help

Hi Athur

Even I am facing same issue for my internal project which uses Polymerjs1. I have loaded webcomponents-lite.min.js as suggested in https://developers.google.com/web/updates/2019/07/web-components-time-to-upgrade#load-the-v0-polyfills. But it still does not work.

DO you know any workaround?

[adesh70695]

The issue is fixed for me now. Check the path for webcomponents and add them in correct place.

Webcomponent file is not able to load any imports

[diksha0291]

I have somehow fixed the errors that i was facing, it was due to loading of webcomponent js in multiple html.

The new issue now I am facing is all files of <link rel="import" are loaded by webcomponent js , but they are not imported in document. Could you please assist here
