Example

var CE = require('create-element-ns')
var el = CE.el

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

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

// partial application to reate multiple modified clones
var pFactory = el('p', {textContent: 'x', partial: true}),
    pEl1 = pFactory({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):

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

If there is no tagName defined or if there is a partial property {partial: true} in the arguments, the function returns a factory instead of an element.

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: 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

• CE.global.document injects an external document API like jsdom. Uses the global document if not specified.
• CE.namespaces adds additional namespace prefix (svg is already defined). E.g. CE.namespaces.xlink: 'http://www.w3.org/1999/xlink'
• CE.decorators to add element decorators E.g. CE.decorators.a = CE.decorators.attributes
