You gotta install crypto-js using

npm install crypto-js

In your js files, you have to import module you wanna use

import sha256 from 'crypto-js/sha256';

Now you can use those functions

sha256(nonce + message);

You have do define message and nonce before this

Thanks, can you please explain to me why doesn't import * as crypto from crypto-js work?

@RyanDsouza, in-order to do import *, all modules has to be exported. That's not the case with crypto-js if you look at the code for sha256.js, github.com/brix/crypto-js/blob/develop/src/sha256.js. They're just defining a function . Check out my other answer about how export and import works in node stackoverflow.com/questions/21117160/…
