property-information

Info on the properties and attributes of the web platform (HTML, SVG, ARIA, XML, XMLNS, XLink).

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 16+), install with npm:

npm install property-information

In Deno with esm.sh:

import * as propertyInformation from 'https://esm.sh/property-information@7'

In browsers with esm.sh:

<script type="module">
  import * as propertyInformation from 'https://esm.sh/property-information@7?bundle'
</script>

Use

import {find, html, svg} 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:

{attribute: 'class', property: 'className', spaceSeparated: true, space: 'html'}
{attribute: 'horiz-adv-x', number: true, property: 'horizAdvX', space: 'svg'}
{attribute: 'xlink:arcrole', property: 'xLinkArcRole', space: 'xlink'}
{attribute: 'xml:lang', property: 'xmlLang', space: 'xml'}
{attribute: 'aria-valuenow', number: true, property: 'ariaValueNow'}

API

This package exports the identifiers find, hastToReact, html, normalize, and svg. There is no default export. It exports the TypeScript types Info, Schema, and Space.

`Info`

Info on a property (TypeScript type).

Fields

attribute (string) — attribute name for the property that could be used in markup (such as 'aria-describedby', 'allowfullscreen', 'xml:lang', 'for', or 'charoff')
booleanish (boolean) — the property is like a boolean (such as draggable); these properties have both an on and off state when defined, and another state when not defined
boolean (boolean) — the property is a boolean (such as hidden); these properties have an on state when defined and an off state when not defined
commaOrSpaceSeparated (boolean) — the property is a list separated by spaces or commas (such as strokeDashArray)
commaSeparated (boolean) — the property is a list separated by commas (such as coords)
defined (boolean) — the property is defined by a space; this is the case for values in HTML (including data and ARIA), SVG, XML, XMLNS, and XLink; not defined properties can only be found through find
mustUseProperty (boolean) — when working with the DOM, this property has to be changed as a field on the element, instead of through setAttribute (this is true only for 'checked', 'multiple', 'muted', and 'selected')
number (boolean) — the property is a number (such as height)
overloadedBoolean (boolean) — the property is like a boolean (such as download); these properties have an on state and more states when defined and an off state when not defined
property (string) — JavaScript-style camel-cased name; based on the DOM but sometimes different (such as 'ariaDescribedBy', 'allowFullScreen', 'xmlLang', 'htmlFor', 'charOff')
spaceSeparated (boolean) — the property is a list separated by spaces (such as className)
space (Space or undefined) — space of the property

`Schema`

Schema for a primary space (TypeScript type).

Fields

normal (Record<string, string>) — object mapping normalized attributes and properties to properly cased properties
property (Record<string, Info>) — object mapping properties to info
space ('html' or 'svg') — primary space of the schema

`Space`

Space of a property (TypeScript type).

Type

type Space = 'html' | 'svg' | 'xlink' | 'xmlns' | 'xml'

`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) — schema; either the html or svg export
name (string) — an attribute-like or property-like name; it will be passed through normalize to hopefully 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'}

`hastToReact`

Special cases for React (Record<string, string>).

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. If it is, use the corresponding value.

`html`

Schema for HTML, with info on properties from HTML itself and related embedded spaces (ARIA, XML, XMLNS, XLink).

Example

console.log(html.property.htmlFor)
// => {attribute: 'for', property: 'htmlFor', spaceSeparated: true, space: 'html'}
console.log(html.property.unknown)
// => undefined

`normalize(name)`

Get the cleaned case insensitive form of an attribute or property.

Parameters

name (string) — an attribute-like or property-like name

Returns

Value (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'

`svg`

Schema for SVG, with info on properties from SVG itself and related embedded spaces (ARIA, XML, XMLNS, XLink).

Example

console.log(svg.property.viewBox)
// => {attribute: 'viewBox', property: 'viewBox', space: 'svg'}
console.log(svg.property.unknown)
// => undefined

Compatibility

This package is at least compatible with all maintained versions of Node.js. As of now, that is Node.js 16+. It also works in Deno and modern browsers.
