rules.push({
                test: /perspective\.wasm\.js$/,
                include: this.options.load_path,
                use: {
                    loader: PSP_WORKER_LOADER,
                    options: this.options.workerLoaderOptions
                }
            });
        }

        rules.push({
            test: /\.js$/,
            loader: "source-map-loader"
        });

        const perspective_config = get_config();
        if (perspective_config) {
            rules.push({

                            replace: JSON.stringify(perspective_config, null, 4)
                        }
