vue-hooks
POC for using React Hooks in Vue. Totally experimental, don't use this in production.
React-style Hooks
import Vue from "vue"
import { withHooks, useState, useEffect } from "vue-hooks"
// a custom hook...
function useWindowWidth() {
const [width, setWidth] = useState(window.innerWidth)
const handleResize = () => {
setWidth(window.innerWidth)
};
useEffect(() => {
window.addEventListener("resize", handleResize)
return () => {
window.removeEventListener("resize", handleResize)
}
}, [])
return width
}
const Foo = withHooks(h => {
// state
const [count, setCount] = useState(0)
// effect
useEffect(() => {
document.title = "count is " + count
})
// custom hook
const width = useWindowWidth()
return h("div", [
h("span", `count is: ${count}`),
h(
"button",
{
on: {
click: () => setCount(count + 1)
}
},
"+"
),
h("div", `window width is: ${width}`)
])
})
// just so you know this is Vue...
new Vue({
el: "#app",
render(h) {
return h("div", [h(Foo), h(Foo)])
}
})
Vue-style Hooks
API that maps Vue's existing API.
import {
withHooks,
useData,
useComputed,
useWatch,
useMounted,
useUpdated,
useDestroyed
} from "vue-hooks"
const Foo = withHooks(h => {
const data = useData({
count: 0
})
const double = useComputed(() => data.count * 2)
useWatch(() => data.count, (val, prevVal) => {
console.log(`count is: ${val}`)
})
useMounted(() => {
console.log('mounted!')
})
useUpdated(() => {
console.log('updated!')
})
useDestroyed(() => {
console.log('destroyed!')
})
return h('div', [
h('div', `count is ${data.count}`),
h('div', `double count is ${double}`),
h('button', { on: { click: () => {
// still got that direct mutation!
data.count++
}}}, 'count++')
])
})
Usage in Normal Vue Components
import { hooks, useData, useComputed } from 'vue-hooks'
Vue.use(hooks)
new Vue({
template: `
<div @click="data.count++">
{{ data.count }} {{ double }}
</div>
`,
hooks() {
const data = useData({
count: 0
})
const double = useComputed(() => data.count * 2)
return {
data,
double
}
}
})
