ReferenceError: globalThis is not defined in old browsers

[OliverWall]

Hi.
Big thanks for you libriary. It very comfortable and functionallity libriary.

Problem:
I developed react component using react-imask ^6.0.0, but i found a bug in production of several users who use old browser.

Example

Workspace:
mozilla 58.0 or other old browser
test application for you

Run app in firefox.

ErrorMessage: ReferenceError: globalThis is not defined

What can i do? I have several users in production and they get this error, because of this I can't use your library =(

Will Its possible fix in next release?

I recently updated my imask library from 6.0.1 to 6.0.3 and ran into the same problem.
Clients using old browsers and IE will get the same reference error.

this isn't a new issue: #296

[OliverWall]

Do I understand correctly that globalThis will be removed in the next release 6.0.4?

Hello guys! Thanks for using imask and helping to improve it.

Since 6.0.0 only umd build contains polyfills. If you are using bundlers then probably you are using es build. So you have to include polyfills manually according to environment you want to support.
List of all polyfills to support down to ie 11 is here: https://github.com/uNmAnNeR/imaskjs/blob/master/packages/imask/src/polyfills.js
As you can see, there are some more options except globalThis.

Here is interersting discussion about polyfilling: w3ctag/polyfills#6 (comment)

@OliverWall no, globalThis will be here
@stijnbollen #296 is little bit different but directed me to exclude globalThis along side with other polyfills.

Please don't close this issue until it will be in a guide. I can't get why this still is not described. Really sorry about that.

[OliverWall]

Thanks for answer.

I will wait for help or the guide from you. Right now i use react-imask v.6.0.3 and still get error in this compoent. I installed package from NPM.

@OliverWall
the solution is pretty simple:

• npm install core-js
• copy polyfills that target platform requires from https://github.com/uNmAnNeR/imaskjs/blob/master/packages/imask/src/polyfills.js

If you need only globalThis polyfill, then also this one could be used: https://github.com/ungap/global-this/

polyfills should be imported before imask
