I love Node.js and MongoDB (A database that goes well with Node). I will use it for embedded systems and backends for web apps. I have questions for frontend JS:
Which front end JS framework is good for PWAs(progressive web apps)
Most other frontend frameworks support Vue. For e.g. Ionic..
The server side rendering can bring magic of SEO friendly sites while being single page application.
I've been using AngularJS and Vue.js extensively and can recommend AngularJS in a more enterprise environment and Vue.js for personal projects. AngularJS has, in my humble opinion, a lot of boilerplate code, which is useful keeping things organised in a team setup. Vue.js has a more minimalistic approach.
