require.main === module is different after ncc

[ajcrites]

This is node.js's recommended method for determining the main module.

If you have a file like:

// index.js
console.log(require.main === module);

$ node .
true
$ ncc run .        # or build
false

ncc should have the output file function the same as when using node.

Can't this be fixed by simply doing this:

{
    plugins: [
        new webpack.DefinePlugin( {
            "require.main": "require.main",
        } ),
    ],
}
