HyperAxe
An enchanted hyperscript weapon.
npm install hyperaxe
var { body, h1 } = require('hyperaxe')
body(
h1('hello world')
)
// => <body><h1>hello world</h1></body>
Usage
Exports all HTML tags.
var { a, img, video } = require('hyperaxe')
a({ href: '#' }, 'click')
// <a href="#">click</a>
img({ src: 'cats.gif', alt: 'lolcats' })
// <img src="cats.gif" alt="lolcats">
video({ src: 'dogs.mp4', autoplay: true })
// <video src="dogs.mp4" autoplay="true"></video>
Default export accepts a tag and returns an element factory.
var x = require('hyperaxe')
var p = x('p')
p('over 9000')
// <p>over 9000</p>
CSS shorthand works too.
var x = require('hyperaxe')
var horse = x('.horse.with-hands')
horse('neigh')
// <div class="horse with-hands">neigh</div>
Makes creating custom components easy.
var x = require('hyperaxe')
var siteNav = (...links) => x('nav.site')(
links.map(link =>
x('a.link')({ href: link.href }, link.text)
)
)
x.body(
siteNav(
{ href: '#apps', text: 'apps' },
{ href: '#games', text: 'games' }
)
)
// <body>
// <nav class="site">
// <a class="link" href="#apps">apps</a>
// <a class="link" href="#games">games</a>
// </nav>
// </body>
Example
Here's a counter increment example using nanochoo:
var { body, button, h1 } = require('hyperaxe')
var nano = require('nanochoo')
var app = nano()
app.use(store)
app.view(view)
app.mount('body')
function view (state, emit) {
return body(
h1(`count is ${state.count}`),
button({ onclick }, 'Increment')
)
function onclick () {
emit('increment', 1)
}
}
function store (state, emitter) {
state.count = 0
emitter.on('increment', function (count) {
state.count += count
emitter.emit('render')
})
}
API
hyperaxe
hyperaxe(tag) => ([props], [...children]) => HTMLElement
tagstring - valid HTML tag name or CSS shorthand (required)propsobject - HTML attributes (optional)childrennode, string, number, array - child nodes or primitives (optional)
Returns a function that creates HTML elements.
The factory is variadic, so any number of children are accepted.
x('.variadic')(
x('h1')('hi'),
x('h2')('hello'),
x('h3')('hey'),
x('h4')('howdy')
)
Arrays of children also work.
var kids = [
x('p')('Once upon a time,'),
x('p')('there was a variadic function,'),
x('p')('that also accepted arrays.')
]
x('.arrays')(kids)
In a browser context, the object returned by the factory is an HTMLElement object. In a server (node) context, the object returned is an instance of html-element. In both contexts, the stringified HTML is accessible via the outerHTML attribute.
hyperaxe[tag]
All HTML tags are attached to hyperaxe as keys.
They return the same function as described above, with the tag argument prefilled.
Think of it as a kind of partial application.
The main motivation for doing this is convenience.
var { p } = require('hyperaxe')
p('this is convenient')
You can pass raw HTML by setting the innerHTML property of an element.
var { div } = require('hyperaxe')
div({ innerHTML: '<p>Raw HTML!' })
hyperaxe.createFactory(h)
Creates a hyperaxe element factory for a given hyperscript implementation (h).
If you use another implementation than hyperscript proper, you can exclude that dependency by using require('hyperaxe/factory'). For the time being, no other implementations are tested though, so wield at your own peril!
hyperaxe.getFactory(h)
Same as createFactory, except it only creates a new factory on the first call and returns a cached version after that.
