@serwist/webpack-plugin/dist/chunks/perform-child-compilation.js

A plugin for your webpack build process, helping you generate a manifest of local files that should be precached.

    return p.replace(/\\/g, "/").replace(/(?<!^)\/+/g, "/");

    }
    return originalPath;
};

const performChildCompilation = async (compiler, compilation, name, src, dest, plugins)=>{

        filename: dest
    }, plugins);
    new compiler.webpack.webworker.WebWorkerTemplatePlugin().apply(childCompiler);
