@hpsharon, @kuflash i got the same problem, Uncaught TypeError: d.default.writeFileSync is not a function. my node version is 9.10.1, i put this in index.js, new Sitemap(router) .build('http://localhost:8080/') .save('./sitemap.xml');

this works for me "scripts": { "start:dev": "webpack-dev-server --open --config ./webpack/webpack.config.dev.js" } "devDependencies": { "webpack": "^3.4.1", "webpack-dev-server": "^2.6.1" }

upgrading webpack also works fine, or you can just use the CDNs in index.html
