Hello there,

Is there any plan to update to pdf.js v2.4.456?

This newer release of pdf.js seems to include much better modularity. It includes more or less the work of nearly 6 months with several bugfixes to the application as well as the handling of PDFs

I see. IE10 and IE11 not begin the best example of a modern browser, at somepoint pdfjs probably wants to use more features of modern JS. It may not be the only one that come up.

We only use evergreen browsers in the last 5 years of projects. But if I had to perhaps I would suggest using a polyfill:

https://www.npmjs.com/package/weakmap-polyfill or https://github.com/ungap/weakmap

The reason, is there are tons of improvements to pdfjs, so I guess the polyfill, working, would be the better solution while taking all other advanges.

The mozilla guys mentioned in the changelog something interesting:

“From now on we produce a non-translated/non-polyfilled build for modern browsers by default. However, we also provide the translated/polyfilled build for older browsers in a separate bundle (with the -es5-dist.zip suffix).” So, they do provide a separate bundle that has such compatibility.

Not sure how to make such optional dependency work. Some libraries use peer dependency, and you do whatever you want in your webapp at the end.

In the meantime, after many months a new release appeared yesterday, it includes performance optimizations/improvements:
