If you have Errors like this:

Error: Cannot resolve module 'fs'

so you need to modify your webpack config file:

...
target: 'node',
node: {
    fs: "empty",
    __dirname: false,
}
...

If you have problem with jszip or mkdirp, then you need also add these lines:

...
externals: [
    {
        './jszip': 'jszip',
        './cptable': 'var cptable',
        'Mkdirp': 'mkdirp',
        'Xlsx': 'xlsx'
    }
]
...
