Compatibility with IE11 about bwip-js

[metafloor]

You would likely have to go back to version 1 to get IE11 compatibility, but I would not recommend that. There have been a lot of bug fixes in the cross-compiled code, plus the BWIPP postscript source code has progressed considerably since then.

A better approach would be to use webpack to translate/polyfill the current release to ES5 - [ "web", "es5" ] target - with bwip-js/dist/bwip-js.js as the source.

Hi, thanks for reply. I am almost unaware of HTML/Js programming. Do you mean by useing webpack to translate/polyfill the current release to ES5, it will work in ie11?

[metafloor]

Yes. My understanding is that IE11 was mostly ES5 compliant, and implemented some ES6 features. For example, Uint8Array. Downgrading the latest bwip-js release to ES5 will incur runtime cost, but you're working with such an ancient javascript engine that performance is likely the least of your worries....

Hi, thanks for help. I will be thankful if you could guide me a little how to convert latest release to ES5.

I am not proficient with webpack - just use a minimal config of it to test tree shaking with this project. There are tons of websites that show how to use it. Plus its reference and user manuals are pretty good. Good luck!
