List of Supported Browsers / Versions and Suggested Polyfils

[konung]

Hi

1. I was wondering if there is a list of supported browsers and versions of those browsers.
2. And possibly a list of polyfills for legacy ones?

Specifically, I have a requirement for an app to be run in a corporate environment where for various reasons they have legacy computers with IE 11. Those computers can't be updated or replaced and are limited to corporate network only - so no public internet (for security reasons). I'm considering using web-awesome for the internal application that those computers will access - among other users.

I'm wondering if Web Awesome (or Shoelace 2) is a good option, and can be made to work on IE 11 through some polyfills? I know IE 11 supports custom elements through shadow DOM generally speaking, the question if WebAwesome will work in IE 11

Traditionally, Shoelace has had a "last two major versions" support policy for evergreen browsers. We may expand this a bit for Web Awesome, but IE 11 has never been on the list of supported browsers for either project.

It's worth noting that support for Internet Explorer ended on June 15, 2022. While I realize some organizations may continue to use it against Microsoft's advice to switch to Edge via "Internet Explorer Mode", it doesn't make sense for us to target that browser as many of the modern APIs we use would need to be polyfilled and a handful likely can't be properly polyfilled.

I know that's probably not what you want to hear, but hopefully these orgs are able to stop using an unsupported, antiquated browser sooner than later!

I hear you .

Unfortunately that's not an option update or replace these systems.

In automotive and healthcare industry for example there are systems that are 20-30 years old that are never going to be replaced, upgraded or re-built from scratch, because the companies/people that built them are no longer in busines, long retired and there is not enough market to justify developing and building new devices, with similar features , because they serve legacy markets.

So all IT and sysadmins can do is restrict them to intranets , lock them down as much as possible , and hope for the best.

And the only feasible way to develop any new admin software and provide access to is via web - thankfully they can s to ll run IE 11 or older ESR Firefox versions .

Not asking webawesome to support this edge 😂🤦‍♂️ case. Believe me - if we could put newer modern systems in place - we would . Just wondering if polyfills could work, so we can provide access to newer services . I guess will stick to html , cas , and jQuery 😀

Yup. Its quite unfortunate that this is the case.

Unfortunately I expect this to be a constant cat and mouse game for you of trying to get polyfills working.

Particularly newer CSS features such as :has(), the color-mix API, and a number of other of features that probably arent possible to polyfill in IE11, in addition, we have other things like the popover API, dialog element, ElementInternals, etc.

I'm sorry you've found yourself in this situation, and im not sure there's a whole lot we can do to support you :/
