|
||
[**hast**][hast] utility to create [*trees*][tree] in HTML or SVG.
|
||
|
||
Similar to [`hyperscript`][hyperscript], [`virtual-dom/h`][virtual-hyperscript],
|
||
[`React.createElement`][react], and [Vue’s `createElement`][vue],
|
||
but for [**hast**][hast].
|
||
|
||
Use [`unist-builder`][u] to create any [**unist**][unist] tree.
|
||
|
||
## Install
|
||
|
||
[npm][]:
|
||
|
||
```sh
|
||
npm install hastscript
|
||
```
|
||
|
||
## Use
|
||
|
||
```js
|
||
var h = require('hastscript')
|
||
var s = require('hastscript/svg')
|
||
|
||
// Children as an array:
|
||
console.log(
|
||
h('.foo#some-id', [
|
||
h('span', 'some text'),
|
||
h('input', {type: 'text', value: 'foo'}),
|
||
h('a.alpha', {class: 'bravo charlie', download: 'download'}, [
|
||
'delta',
|
||
'echo'
|
||
])
|
||
])
|
||
)
|
||
|
||
// Children as arguments:
|
||
console.log(
|
||
h(
|
||
'form',
|
||
{method: 'POST'},
|
||
h('input', {type: 'text', name: 'foo'}),
|
||
h('input', {type: 'text', name: 'bar'}),
|
||
h('input', {type: 'submit', value: 'send'})
|
||
)
|
||
)
|
||
|
||
// SVG:
|
||
console.log(
|
||
s('svg', {xmlns: 'http://www.w3.org/2000/svg', viewbox: '0 0 500 500'}, [
|
||
s('title', 'SVG `<circle>` element'),
|
||
s('circle', {cx: 120, cy: 120, r: 100})
|
||
])
|
||
)
|
||
```
|
||
|
||
Yields:
|
||
|
||
```js
|
||
{
|
||
type: 'element',
|
||
tagName: 'div',
|
||
properties: {className: ['foo'], id: 'some-id'},
|
||
children: [
|

{
|

type: 'element',

|

{

tagName: 'a',
|

properties: {className: ['alpha', 'bravo', 'charlie'], download: true},
|

children: [{type: 'text', value: 'delta'}, {type: 'text', value: 'echo'}]
|

children: []
|
||
},
|
||
{
|
||
type: 'element',
|
||
tagName: 'input',
|
||
properties: {type: 'submit', value: 'send'},
|
||
children: []
|
||
}
|
||
]
|
||
}
|
||
{
|
||
type: 'element',
|
||
tagName: 'svg',
|
||
properties: {xmlns: 'http://www.w3.org/2000/svg', viewBox: '0 0 500 500'},
|
||
children: [
|
||
{
|
||
type: 'element',
|
||
tagName: 'title',
|
||
properties: {},
|
||
children: [{type: 'text', value: 'SVG `<circle>` element'}]
|
||
},
|
||
{
|
||
type: 'element',
|
||
tagName: 'circle',
|
||
properties: {cx: 120, cy: 120, r: 100},
|
||
children: []
|
||
}
|
||
]
|
||
}
|
||
```
|
||
|
||
## API
|
||
|
||
### `h(selector?[, properties][, ...children])`
|
||
|
||
### `s(selector?[, properties][, ...children])`
|
||
|
||
DSL to create virtual [**hast**][hast] [*trees*][tree] for HTML or SVG.
|
||
|
||
##### Parameters
|
||
|
||
###### `selector`
|
||
|
||
Simple CSS selector (`string`, optional).
|
||
Can contain a tag name (`foo`), IDs (`#bar`), and classes (`.baz`).
|
||
If there is no tag name in the selector, `h` defaults to a `div` element,
|
||
and `s` to a `g` element.
|
||
`selector` is parsed by [`hast-util-parse-selector`][parse-selector].
|
||
|
||
###### `properties`
|
||
|
||
Map of properties (`Object.<*>`, optional).
|
||
|
||
###### `children`
|
||
|
||
(Lists of) child nodes (`string`, `Node`, `Array.<string|Node>`, optional).
|
||
When strings are encountered, they are mapped to [`text`][text] nodes.
|
||
|
||
##### Returns
|
||
|
||
[`Element`][element].
|
||
|
||
## Security
|
||
|
||
Use of `hastscript` can open you up to a [cross-site scripting (XSS)][xss]
|
||
attack as values are injected into the syntax tree.
|
||
The following example shows how a script is injected that runs when loaded in a
|
||
browser.
|
||
|
||
```js
|
||
var tree = {type: 'root', children: []}
|
||
|
||
tree.children.push(h('script', 'alert(1)'))
|
||
```
|
||
|
||
Yields:
|
||
|
||
```html
|
||
<script>alert(1)</script>
|
||
```
|
||
|
||
The following example shows how an image is injected that fails loading and
|
||
therefore runs code in a browser.
|
||
|
||
```js
|
||
var tree = {type: 'root', children: []}
|
||
|
||
// Somehow someone injected these properties instead of an expected `src` and
|
||
// `alt`:
|
||
var otherProps = {src: 'x', onError: 'alert(2)'}
|
||
|
||
tree.children.push(h('img', {src: 'default.png', ...otherProps}))
|
||
```
|
||
|
||
Yields:
|
||
|
||
```html
|
||
<img src="x" onerror="alert(2)">
|
||
```
|
||
|
||
The following example shows how code can run in a browser because someone stored
|
||
an object in a database instead of the expected string.
|
||
|
||
```js
|
||
var tree = {type: 'root', children: []}
|
||
|
||
// Somehow this isn’t the expected `'wooorm'`.
|
||
var username = {
|
||
type: 'element',
|
||
tagName: 'script',
|
||
children: [{type: 'text', value: 'alert(3)'}]
|
||
}
|
||
|
||
tree.children.push(h('span.handle', username))
|
||
```
|
||
|
||
Yields:
|
||
|
||
```html
|
||
<span class="handle"><script>alert(3)</script></span>
|
||
```
|
||
|
||
Either do not use user input in `hastscript` or use
|
||
[`hast-util-santize`][sanitize].
