Package Exports

hast-to-hyperscript

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (hast-to-hyperscript) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

hast-to-hyperscript

Transform HAST to something else through a hyperscript DSL.

Installation

npm:

npm install hast-to-hyperscript

Usage

var toH = require('hast-to-hyperscript');
var h = require('hyperscript');

var tree = { type: 'element',
   tagName: 'p',
   properties: { id: 'alpha', className: [ 'bravo' ] },
   children:
    [ { type: 'text',
        value: 'charlie ' },
      { type: 'element',
        tagName: 'strong',
        properties: { style: 'color: red;' },
        children:
         [ { type: 'text',
             value: 'delta' } ] },
      { type: 'text',
        value: ' echo.' } ] }

// Transform (`hyperscript` needs `outerHTML` to stringify):
var doc = toH(h, tree).outerHTML;

Yields:

<p class="bravo" id="alpha">charlie <strong>delta</strong> echo.</p>

API

`toH(h, node[, prefix])`

Transform HAST to something else through a hyperscript DSL.

Parameters

h (Function)
node (Element)
prefix (string or boolean, optional) — Prefix to use as a prefix for keys passed in attrs to h(), this behaviour is turned off by passing false, turned on by passing a string. By default, h- is used as a prefix if the given h is detected as being virtual-dom/h or React.createElement

Returns

* — Anything returned by invoking h().

`function h(name, attrs, children)`

Transform HAST to something else through a hyperscript DSL.

Parameters

name (string) — Tag-name of element to create
attrs (Object.<string>) — Attributes to set
children (Array.<* | string>) — List of children and text, where children are the result of invoking h() previously

Returns

* — Anything.

Caveats

Although there are lots of libs mentioning support for this interface, there are significant differences between them. For example, hyperscript doesn’t support classes in attrs, virtual-dom/h needs an attributes object inside attrs most of the time. hast-to-hyperscript works around these differences for:
