Any idea on the purpose of binding the require fn, module.require.bind(module)?

• ncc builds are failing with Error: Cannot find module 'crypto' at this line.
• This PR is the temporary fix to avoid this issue.

ncc transforms the code to this:

exports.crypto = (() => {
    const webCrypto = typeof self === "object" && "crypto" in self ? self.crypto : undefined;
    const nodeRequire =  true &&
        __nccwpck_require__(84310).bind(module); <-- Note the 
    return {
        node: nodeRequire && !webCrypto ? require("crypto") : undefined,
        web: webCrypto
    };
})();

/***/ 84310:
/***/ ((module) => {

function webpackEmptyContext(req) {
	var e = new Error("Cannot find module '" + req + "'");
	e.code = 'MODULE_NOT_FOUND';
	throw e;
}
webpackEmptyContext.keys = () => ([]);
webpackEmptyContext.resolve = webpackEmptyContext;
webpackEmptyContext.id = 84310;
module.exports = webpackEmptyContext;

/***/ }),

This leads to the EA crash looping with this error:

Error: Cannot find module 'crypto'

I think webpack is trying to bundle crypto when it's a native module. You could try the following ncc flag: --external crypto.

If that doesn't work, I would try upgrading ncc to latest to see if it fixes the require statement.

[aiagentdev-1990]

I've tried both of those already and still no luck :(

[aiagentdev-1990]

I even tried building the js-ethereum-cryptography project directly and still see the issue.

[HenryNguyen5]

I’m not sure how important it is to not patch a package. But you could also abandon ncc and switch it up for something like swc or esbuild + do a prod only install for deps.

[krebernisak]

@cds95 we should investigate if we can remove 0.1.3 version altogether and move to v1

[aiagentdev-1990]

@krebernisak @HenryNguyen5 I've opened an issue in the js-ethereum-cryptography repo here.

Edit: I've been told to open another issue at NCC, which I have done here vercel/ncc#985

[boxhock]

Was a fix for this already merged in? Should we close this PR?
