Error "cannot find module 'xxx'" when bundled with webpack

[madtisa]

Description

I was unable to configure webpack the way that __non_webpack__require__ is defined, so using bundle always results in error: "Cannot find module". Is it a bug or am I missing something (and if so, how can I make it work)?

Bundled real require looks like this (all requires are replaced to __webpack__require__s, but __non_webpack__require__ is ignored and is always undefined):

function realRequire(modulePath) {
    if (typeof __non_webpack__require__ === 'function') {
        return __non_webpack__require__(modulePath)
    }

    return __webpack_require__("./node_modules/real-require/src sync recursive")(modulePath)
}

Demos that displays this behavior

• Demo project 1 (localized example): imitate-real-require.zip
• Demo project 2 (usage example): bundle-real-require.zip

As a workaround you can forcefully define __non_webpack__require__ to globalThis.require in webpack.config.js:

const {DefinePlugin} = require('webpack');
module.exports = {
    ...
    plugins: [
        new DefinePlugin({
            __non_webpack__require__: 'globalThis.require',
        }),
    ]
}
