Can you please remove .save()?

qrcode-svg/lib/qrcode.js

Lines 405 to 420 in 47d56ec

/** Writes QR Code image to a file */
QRCode.prototype.save = function(file, callback) {
var data = this.svg();
if (typeof callback != "function") {
callback = function(error, result) { };
}
try {
//Package 'fs' is available in node.js but not in a web browser
var fs = require('fs');
fs.writeFile(file, data, callback);
}
catch (e) {
//Sorry, 'fs' is not available
callback(e);
}
};

Saving files to disk is very easy in node and the developer can decide wether they need to use sync or async:

fs.writeFileSync("qr.svg", new QRCode("abc").svg());

I'm trying this in an angular project and having the same warning.

Projects that depend on fs, you can just add the code below to your webpack's configuration file:

module.exports = {
  // ...
  node: {
    fs: 'empty',
  },
  // ...
};

With webpack 5/laravel-mix 6 this sould be:

mix.webpackConfig({
    resolve: {
        fallback: {
            fs: false
        }
    }
});

Use eval('require') instead of require to avoid bundler error hzy/qrcode-svg
