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 they’re booleans or contain lists of space separated numbers.

When should I use this?

You can use this package if you’re 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. In Node.js (version 14.14+, 16.0+), install with npm:

npm install property-information

In Deno with esm.sh:

import * as propertyInformation from 'https://esm.sh/property-information@6'

In browsers with esm.sh:

<script type="module">
  import * as propertyInformation from 'https://esm.sh/property-information@6?bundle'
</script>

Use

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:

{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 has hints about the value of the property.

name can also be a valid data attribute or property, in which case an Info object with the correctly cased attribute and property is returned.

name can be an unknown attribute, in which case an 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) — either the html or svg export
name (string) — an attribute-like or property-like name that is passed through normalize to find the correct info

Returns

Info.

Example

Aside from the aforementioned example, which shows known HTML, SVG, XML, XLink, and ARIA support, data properties, and attributes are also supported:

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:

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.

Example

html.normal[normalize('for')] // => 'htmlFor'
svg.normal[normalize('VIEWBOX')] // => 'viewBox'
html.normal[normalize('unknown')] // => undefined
html.normal[normalize('accept-charset')] // => 'acceptCharset'

`html`

`svg`

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

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>) — object mapping properties to info

`Info`

Info on a property.

space ('html', 'svg', 'xml', 'xlink', 'xmlns', optional) — space 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. 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.
