Resolving issues with JavaScript caused by Polymer updates

I am a novice when it comes to working with Polymer. From what I have gathered, there seems to be compatibility issues with Mozilla and Safari. After researching on StackOverflow, I found that adding

addEventListener('WebComponentsReady', function() {
});

could potentially resolve the browser compatibility issues. I implemented this solution in my code and it did help with displaying content properly in Mozilla. However, it ended up causing conflicts with the JavaScript code I had written alongside Polymer. I attempted two different approaches, the first one being:

addEventListener('WebComponentsReady', function() {
    Polymer({
      is: "main-header"
    }); });

Even after trying this method, error logs continued to appear in the console. When I tried wrapping the entire script inside the event listener, it still did not work. For example:

 addEventListener('WebComponentsReady', function() {
    Polymer({
      is: "main-header"
    }); 
    // extra code here
 });

I suspect that enclosing the addEventListener within the whole code might be contributing to the issue. Does anyone have suggestions for resolving this problem? Are there any alternative solutions besides utilizing an event listener in the code?

Answer №1

If you're looking for a solution, consider using Polymer-CLI

It already has some polyfills built-in. Although I'm not exactly sure which ones are included, the one you're asking about might be there.

Answer №2

After some investigation, I discovered that utilizing

addEventListener('WebComponentsReady', function() {
});

was causing issues with my JavaScript due to a clash with

addEventListener('HTMLImportsReady', function() {
});

I ultimately had to eliminate it in order to ensure the script ran smoothly.
