A simple library for composable DOM elements using tagged template strings.
For a more in depth tutorial on getting started, please check out the wiki.
Create an element:
// list.js
var bel = require('bel')
module.exports = function (items) {
return bel`<ul>
${items.map(function (item) {
return bel`<li>${item}</li>`
})}
</ul>`
}
Then pass data to it and add to the DOM:
// app.js
var createList = require('./list.js')
var list = createList([
'grizzly',
'polar',
'brown'
])
document.body.appendChild(list)
// list.js
var bel = require('bel')
// The DOM is built by the data passed in
module.exports = function (items, onselected) {
function render () {
return bel`<ul>
${items.map(function (item) {
return bel`<li>${button(item.id, item.label)}</li>`
})}
</ul>`
}
function button (id, label) {
return bel`<button onclick=${function () {
// Then action gets sent up
onselected(id)
}}>${label}</button>`
}
var element = render()
return element
}
// app.js
var bel = require('bel')
var list = require('./list.js')
module.exports = function (bears) {
function onselected (id) {
// When a bear is selected, rerender with the newly selected item
// This will use DOM diffing to render, sending the data back down again
element.update(render(id))
}
function render (selected) {
return bel`<div className="app">
<h1>Selected: ${selected}</h1>
${list(bears, onselected)}
</div>`
}
// On first render, we haven't selected anything
var element = render('none')
return element
}
