Webpack 5 support

[Bilge]

It seems this loader is not compatible with webpack 5. When using with Storybook, my story gives ReferenceError: Buffer is not defined. Not sure what that means as I cannot see any line referencing Buffer, but I guess the point here is just that webpack 5 compatibility is needed.

Not twing-loader issue. Add Buffer plugin from webpack. Like this (sorry, this is half-assed answer, just browsing past, this is one of webpack config files that plugs in webpackFinal key in Storybook main.js)

const webpack = require('webpack');

const bufferPlugin = new webpack.ProvidePlugin({
  Buffer: ['buffer', 'Buffer'],
});

module.exports = {
  bufferPlugin,
};
