Angular 10 module depends on 'bignumber.js'. CommonJS or AMD dependencies can cause optimization bailouts.

After upgrading to Angular version 10 I get the message depends on 'bignumber.js'. CommonJS or AMD dependencies can cause optimization bailouts. Are you going to publishing an ES module?

It's the bignumber.mjs file.

See the package.json:

"module": "bignumber.mjs",

Did anyone found a solution how angular build finds the *.mjs file? I have the same problem too.

@phip1611 The way I found was to rename the bignumber.mjs -> bignumber.js There is probably a better way that I don't know 😉

Same issue here, any update?

This is because in Angular you must add this for each CommonJS Dependency: "options": { "allowedCommonJsDependencies": ["bignumber.js"] }

This option tells the compiler to ignore the warning. Not fixing the issue.

I'm not 100% sure why, but importing like that seems to solve the warning:

import { BigNumber } from 'bignumber.js/bignumber';

I confirm this. I changed my imports. Thanks @gabrielbiga
