What is the best JS framework ?

How does it work ?

getters/setters (ES5)

let _name = "joe";

const user = {
    get name() {
        console.log("accès en lecture à la propriété")
        return _name
    },
    set name(value) {
        console.log("accès en écriture à la propriété")
        _name = value
    }
}

How does it work ?

Next in Vue 3 : Proxy (ES6)

const _user = { name: "joe" }

const user = new Proxy(_user, {
    get(obj, key) {
        console.log(`accès en lecture à la propriété ${key}`)
        return Reflect.get(obj, key)
    },
    set (obj, key, value) {
        console.log(`accès en écriture à la propriété ${key} 
                     avec la valeur ${value}`)
        return Reflect.set(obj, key, value)
    }
})

Vue Reactivity System

  • AngularJS 1.x : synchronous dirty-checking
     
  • Angular 2+ : Zones (~= async dirty-checking)
     
  • React : manual updates (setState)
                 manual optimizations (shouldComponentUpdate)
                 diff against a Virtual DOM to optimize rendering
     

  • Vue : auto updates (setters / proxies)
             auto optimization  (dependency tracking)
             diff against a Virtual DOM

Vue@Worldline

PWA La Banque Postale, Jessy Archiles &  Yann Perthuis:

very easy to start, for everyone
very happy with Vue for our PWA

lightweight but less complete than Angular

ewLabs, Arnaud Berthillot:

easiest learning curve, good documentation

quickly adopted and loved by the community
adapted for small to medium web projects

SDCO: used in 3 projects currently in development
Coming soon: a 1-day training session for Vue.js by SDCO

  • Simple:  small API surface, you can start in 2 hours
  • Lightweight: 20kb .min.gzip runtime
  • Versatile: can be used with almost any stack
  • Stable and mature, rich ecosystem
  • Takes the best ideas from competitors
  • Almost no API breaking changes in 4 years

To sum up

Vue is also great to make games
