I ended up using fast-xml-parser instead

Webpack 5 no longer polyfills Node.js core modules automatically which means if you use them in your code running in browsers or alike, you will have to install compatible modules from npm and include them yourself.

I have the same problem, but in my case I don't use some functionalities with xml2js and I've decided my problem with update section resolve in webpack.config:


resolve: {
    fallback: { 
        "stream": require.resolve("stream-browserify"),
        "string_decoder": false,
        "buffer": false,
        "events": false
    }
}
