Build Vue-like components in React. Get the goodness of Vue-reactivty system such as watchers and computed properties and remove the need of using React's setState
completely.
$ npm install --save react-vue-component
-
import {Component} from "react-vue-component"; class App extends Component { state = { name: "Bob", } componentDidMount() { this.name = "Albert"; } watch { name(newName, oldName) { console.log("name has changed!"); }, } computed { fullName(){ return this.name + " Lolzer"; } } methods { changeName() { // Changing name will also change the computed property fullName this.name = "John"; } } render() { // states, methods, and computed properties can be accessed directly via `this` just like in Vue const {name, fullName, changeName} = this; return ( <div> <p>{name}</p> <p>{fullName}</p> <a onClick={() => this.changeName()}>Change my name</a> </div> ) } }
- In Vue, in order to "reactively" add/delete key-value pairs from an object, you will need to use
set(obj, key, value)
anddelete(obj,key)
respectively.
import {Component} from "react-vue-component";
class App extends Component {
state = {
obj : {
name: "Prev"
}
}
methods {
addToObj() {
this.set(this.obj, "age", 20);
}
deleteName() {
this.delete(this.obj, "name");
}
}
watch {
// nested watchers
"obj.name" : (newName, oldName) => {
console.log("Obj.name has changed");
}
"obj.age" : (newAge, oldAge) => {
console.log("Obj.age has changed");
}
}
render() {
const {obj} = this;
return (
<div>
Object.keys(obj).map(key =>
<p><strong>{key}</strong>: {obj[key]}</p>
)
<a onClick={() => this.addToObj()}>Add new key</a>
<a onClick={() => this.deleteName()}>Delete name</a>
</div>
)
}
}

Behind the scenes,
componentWillMount
is being used to inject Vue's reactivity system thus it is made impossible to overwrite. Instead, usebeforeMount
as an equivalent replacement: -
import {Component} from "react-vue-component"; class App extends Component { beforeMount(){ console.log("before mount! component hasnt render yet...") } ... }
- All credits to the Vue core team for their awesome reactivity system.
