+## Nuxt.js
+
+Properly configuring all the discussed aspects of a production-ready server-rendered app can be a daunting task. Luckily, there is an excellent community project that aims to make all of this easier: [Nuxt.js](https://nuxtjs.org/). Nuxt.js is a higher-level framework built on top of the Vue ecosystem which provides an extremely streamlined development experience for writing universal Vue applications. Better yet, you can even use it as a static site generator (with pages authored as single-file Vue components)! We highly recommend giving it a try.
