tagged template string virtual dom builder
This module is similar to JSX, but provided as a standards-compliant ES6 tagged template string function.
hyperx works with virtual-dom,
react,
hyperscript, or any DOM builder with a
hyperscript-style API: h(tagName, attrs, children)
.
You might also want to check out the hyperxify browserify transform to statically compile hyperx into javascript expressions to save sending the hyperx parser down the wire.
Template strings are available in: node 4+, chrome 41, firefox 34, edge, opera 28, safari 9
If you're targeting these platforms, there's no need to use a transpiler!
var vdom = require('virtual-dom')
var hyperx = require('hyperx')
var hx = hyperx(vdom.h)
var title = 'world'
var wow = [1,2,3]
var tree = hx`<div>
<h1 y="ab${1+2}cd">hello ${title}!</h1>
${hx`<i>cool</i>`}
wow
${wow.map(function (w, i) {
return hx`<b>${w}</b>\n`
})}
</div>`
console.log(vdom.create(tree).toString())
output:

var convertTaggedTemplateOutputToDomBuilder = hyperx(function (tagName, attrs, children) {

convertTaggedTemplateOutputToDomBuilder`<h1>hello world</h1>`
// Running this produces: h1 {} [ 'hello world' ]
var hyperx = require('hyperx')
Return a tagged template function hx
from a hyperscript-style factory function
h
.
Values to use for h
:
- virtual-dom -
vdom.h
- react -
React.createElement
- hyperscript - hyperscript
Optionally provide:
opts.concat(a, b)
- custom concatenation function to combine quasiliteral strings with expressions. Theh
factory function will receive the objects returned by the concatenation function and can make specific use of them. This is useful if you want to implement a pre-processor to generate javascript from hyperx syntax.
