Example

var createElementNS = require('create-element-ns')

var createHtmlEl = createElementNS.html.el,
    createHtmlFac = createElementNS.html.el,
    createSvgEl = createElementNS.svg.fn,
    createSvgFac = createElementNS.svg.fn,

// selectors or attributes
var divEl1 = createHtmlEl('div.c1#i1[style="color:blue"].c2', {onclick: function() {}}),
    divEl2 = createHtmlEl('.i1', {style: {color: 'blue'}, props:{className: 'c1 c2', , onclick: function() {}}})

// namespace in different ways
var circleEl1 = createHtmlEl('svg:circle'),
    circleEl2 = createSvgEl('svg:circle'),
    circleEl3 = createHtmlEl('circle[xmlns=http://www.w3.org/2000/svg]')

// elementfactories to create multiple modified clones
function dec(el) {
  el.textContent = 'x'
  return el
}
var pEl0 = pFac(dec),
    pEl1 = pFac({textContent: 'x'})

Features

• namespaced tag and namespaced attribute support
• svg namespace and utility functions pre-defined
• w3 string selector API, including attributes
• element decorators for element properties and attributes
• ability to inject a document API for server and/or testing (e.g. jsdom)
• ability to create an element or an element factory
• ability to create additional namespaces and utility namespaced functions

There are many hyperscript modules out there (docrel, create-element-from-selector, domator, makeelement, simpel to name a few) but they either don't support namespaces, like svg or are more oriented to virtual-dom applications.

API

Main methods

To create an element (methods that return a DOM Element):

• html.el(definition [, options][, content]) => DOM HTMLElement
• svg.el(definition [, options][, content]) => DOM SVGElement

To create an element factory (methods that return an elementFactory that creates DOM Elements):

• html.fn(definition [, options][, content]) => elementFactory
• svg.fn(definition [, options][, content]) => elementFactory

Parameters and outputs

• definition: a string selector, elementFactory or DOM Element
• options: an optional qualifier object of attributes and properties or an optional elementDecorator function
  • qualifier: {properties:{}, attributes:{}, style:{}, dataset:{}}. Alias s, a, p, d, props, attrs
  • elementDecorator(el) => el' modifies an element directly
• content: optional series of string, Element and arrays of strings and Elements
• elementFactory([elementDecorator|optionObject]) => el

Optional additional utilities

• .api(documentAPI) injects an external document API like jsdom. Uses the global document if not specified.
• .ns(prefix, URI) adds additional namespace prefix (svg is already defined). E.g. .ns('xlink', 'http://www.w3.org/1999/xlink')
• .factory(nsDecorators, partial, URI) to create additional namespace functions (html and svg are already defined)
