## What is this?
This package contains lots of info on all the properties and attributes found
on the web platform.
It includes data on HTML, SVG, ARIA, XML, XMLNS, and XLink.
The names of the properties follow [hast][]s sensible naming scheme.
It includes info on what data types attributes hold, such as whether theyre
booleans or contain lists of space separated numbers.
## When should I use this?
You can use this package if youre working with hast, which is an AST for HTML,
or have goals related to ASTs, such as figuring out which properties or
attributes are valid, or what data types they hold.
## Install
This package is [ESM only][esm].
In Node.js (version 14.14+, 16.0+), install with [npm][]:
```sh
npm install property-information
```
In Deno with [`esm.sh`][esmsh]:
```js
import * as propertyInformation from 'https://esm.sh/property-information@6'
```
In browsers with [`esm.sh`][esmsh]:
```html
<script type="module">
import * as propertyInformation from 'https://esm.sh/property-information@6?bundle'
</script>
```
## Use
```js
import {html, svg, find, normalize} from 'property-information'
console.log(find(html, 'className'))
// Or: find(html, 'class')
console.log(find(svg, 'horiz-adv-x'))
// Or: find(svg, 'horizAdvX')
console.log(find(svg, 'xlink:arcrole'))
// Or: find(svg, 'xLinkArcRole')
console.log(find(html, 'xmlLang'))
// Or: find(html, 'xml:lang')
console.log(find(html, 'ariaValueNow'))
// Or: find(html, 'aria-valuenow')
```
Yields:
```js
{space: 'html', attribute: 'class', property: 'className', spaceSeparated: true}
{space: 'svg', attribute: 'horiz-adv-x', property: 'horizAdvX', number: true}
{space: 'xlink', attribute: 'xlink:arcrole', property: 'xLinkArcrole'}
{space: 'xml', attribute: 'xml:lang', property: 'xmlLang'}
{attribute: 'aria-valuenow', property: 'ariaValueNow', number: true}
```
## API
This package exports the identifiers `html`, `svg`, `find`, `normalize`,
and `hastToReact`.
There is no default export.
### `find(schema, name)`
Look up info on a property.
In most cases, the given `schema` contains info on the property.
All standard, most legacy, and some non-standard properties are supported.
For these cases, the returned [`Info`][info] has hints about the value of the
property.
`name` can also be a [valid data attribute or property][data], in which case an
[`Info`][info] object with the correctly cased `attribute` and `property` is
returned.
`name` can be an unknown attribute, in which case an [`Info`][info] object
with `attribute` and `property` set to the given name is returned.
It is not recommended to provide unsupported legacy or recently specced
properties.
#### Parameters
* `schema` ([`Schema`][schema])
— either the `html` or `svg` export
* `name` (`string`)
— an attribute-like or property-like name that is passed through
[`normalize`][normalize] to find the correct info
#### Returns
[`Info`][info].
#### Example
Aside from the aforementioned example, which shows known HTML, SVG, XML, XLink,
and ARIA support, data properties, and attributes are also supported:
```js
console.log(find(html, 'data-date-of-birth'))
// Or: find(html, 'dataDateOfBirth')
// => {attribute: 'data-date-of-birth', property: 'dataDateOfBirth'}
```
Unknown values are passed through untouched:
```js
console.log(find(html, 'un-Known'))
// => {attribute: 'un-Known', property: 'un-Known'}
```
### `normalize(name)`
Get the cleaned case insensitive form of an attribute or property.
#### Parameters
* `name` (`string`)
— an attribute-like or property-like name
#### Returns
`string` that can be used to look up the properly cased property on a
[`Schema`][schema].
#### Example
```js
html.normal[normalize('for')] // => 'htmlFor'
svg.normal[normalize('VIEWBOX')] // => 'viewBox'
html.normal[normalize('unknown')] // => undefined
html.normal[normalize('accept-charset')] // => 'acceptCharset'
```
### `html`
### `svg`
[`Schema`][schema] for either HTML or SVG, containing info on properties from
the primary space (HTML or SVG) and related embedded spaces (ARIA, XML, XMLNS,
XLink).
#### Example
```js
console.log(html.property.htmlFor)
// => {space: 'html', attribute: 'for', property: 'htmlFor' spaceSeparated: true}
console.log(svg.property.viewBox)
// => {space: 'svg', attribute: 'viewBox', property: 'viewBox'}
console.log(html.property.unknown)
// => undefined
```
#### `Schema`
A schema for a primary space.
* `space` (`'html'` or `'svg'`)
— primary space of the schema
* `normal` (`Record<string, string>`)
— object mapping normalized attributes and properties to properly cased
properties
* `property` ([`Record<string, Info>`][info])
— object mapping properties to info
#### `Info`
Info on a property.
* `space` (`'html'`, `'svg'`, `'xml'`, `'xlink'`, `'xmlns'`, optional)
— [space][namespace] of the property
* `attribute` (`string`)
— attribute name for the property that could be used in markup (for
example: `'aria-describedby'`, `'allowfullscreen'`, `'xml:lang'`, `'for'`,
or `'charoff'`)
* `property` (`string`)
— JavaScript-style camel-cased name, based on the DOM, but sometimes
different (for example: `'ariaDescribedBy'`, `'allowFullScreen'`,
`'xmlLang'`, `'htmlFor'`, `'charOff'`)
* `boolean` (`boolean`)
— the property is a `boolean` (for example: `hidden`).
These properties have an on state when defined and an off state when not
defined
* `booleanish` (`boolean`)
— the property is like a `boolean` (for example: `draggable`)
These properties have both an on and off state when defined, and another
state when not defined
* `overloadedBoolean` (`boolean`)
— the property is like a `boolean` (for example: `download`)
These properties have an on state plus more states when defined and an off
state when not defined
* `number` (`boolean`)
— the property is a `number` (for example: `height`)
* `spaceSeparated` (`boolean`)
— the property is a list separated by spaces (for example: `className`)
* `commaSeparated` (`boolean`)
— the property is a list separated by commas (for example: `srcSet`)
* `commaOrSpaceSeparated` (`boolean`)
— the property is a list separated by spaces or commas (for example:
`strokeDashArray`)
* `mustUseProperty` (`boolean`)
— useful when working with the DOM, in which case this property has to be
changed as a field on the element, rather than through `setAttribute`
(this is true only for `'checked'`, `'multiple'`, `'muted'`, and
`'selected'`)
* `defined` (`boolean`)
— the property is [defined by a space](#support).
This is true for values in HTML (including data and ARIA), SVG, XML,
XMLNS, and XLink.
Undefined properties can only be found through `find`
### `hastToReact`
[hast][] is close to [React][], but differs in a couple of cases.
To get a React property from a hast property, check if it is in `hastToReact`
(`Record<string, string>`), if it is, then use the corresponding value,
otherwise, use the hast property.
## Types
This package is fully typed with [TypeScript][].
It exports the additional types `Info` and `Schema`.
## Compatibility
This package is at least compatible with all maintained versions of Node.js.
As of now, that is Node.js 14.14+ and 16.0+.
It also works in Deno and modern browsers.
