@iconify/types
Advanced tools
@iconify/types is a TypeScript package that provides type definitions for Iconify JSON data. It is used to ensure type safety when working with Iconify icons in TypeScript projects.
IconifyJSON
Defines the structure of Iconify JSON data, including properties like prefix, icons, width, and height.
{
"prefix": "mdi",
"icons": {
"home": {
"body": "<path d='M10 20v-6h4v6h5v-8h3L12 3 2 12h3v8z'/>"
}
},
"width": 24,
"height": 24
}IconifyIcon
Defines the structure of an individual icon, including properties like body, width, and height.
{
"body": "<path d='M10 20v-6h4v6h5v-8h3L12 3 2 12h3v8z'/>",
"width": 24,
"height": 24
}IconifyAlias
Defines the structure of an icon alias, including properties like parent and hFlip.
{
"parent": "home",
"hFlip": true
}React Icons provides a collection of popular icon libraries for React applications. Unlike @iconify/types, which focuses on type definitions, react-icons provides ready-to-use React components for icons.
FontAwesome SVG Core is a package for using FontAwesome icons in web projects. It provides a comprehensive set of icons and utilities for managing them, but it is specific to FontAwesome, whereas @iconify/types is more generic.
Material Icons is a package that provides Google's Material Design icons. It is similar to @iconify/types in that it offers a collection of icons, but it is specific to Material Design.
Type definitions for using Iconify libraries and JSON files with TypeScript.
Iconify icon sets are available in several formats:
Each icon is represented by IconifyIcon type. It is a simple object with multiple string, number or boolean attributes.
The only required attribute is:
body that contains inner HTML of icon as string, for example <path d="..."/>Optional attributes are represented by type IconifyOptional. They are split into several types: dimensions (IconifyDimenisons type) and transformations (IconifyTransformations type).
Dimensions attributes:
width viewBox width, number. If missing, value is set to 16height viewBox height, number. If missing, value is set to 16left viewBox left, number. If missing, value is set to 0top viewBox top, number. If missing, value is set to 0Transformations:
rotate icon rotation, number. Iconify icons can be rotated in 90 degrees increments, allowing to reuse same source icon for multiple icons, such as arrow-up being copy of arrow-left rotated by 90 degrees. Values are 0 for 0 degrees, 1 for 90 degrees, 2 for 180 degrees, 3 for 270 degrees. Default value is 0.hFlip horizontal flip, boolean. Similar to rotation, icon can be flipped. It can be used to quickly create aliases, such as arrow-left being alias of arrow-right, but with hFlip set to true. Default value is false.vFlip vertical flip. Default value is false.Example of icon object:
const mdiHandIcon = {
body:
'<path d="M6.58 19h8v3h-8v-3m13.16-7.4c-.19-.2-.45-.32-.74-.32l-.22.03l-3.2 1.69v-1.17l.51-8.93c.03-.55-.39-1.03-.94-1.06c-.55-.03-1.03.39-1.06.94l-.27 4.69h-.24l-1.04.11V2a1 1 0 0 0-1-1c-.54 0-1 .45-1 1v6.41l-.82.37l-.69-5.46c-.07-.55-.57-.94-1.12-.87c-.55.05-.94.55-.87 1.12l.77 6.06l-.38.17c-.13.05-.25.13-.36.2l-1.1-3.89c-.16-.57-.72-.91-1.26-.77c-.53.16-.83.74-.67 1.31l2.57 9.12c0 .03.02.07.03.1l.03.13h.01c.22.57.79 1 1.4 1h6.5c.39 0 .74-.16 1-.43l4.92-4.2l-.76-.77z" fill="currentColor"/>',
width: 24,
height: 24,
};
Iconify JSON format is available from multiple sources:
JSON format structure is available as IconifyJSON type. It is an object with several fields:
prefix icon set prefix, stringicon icons data, object where key is icon name and value is IconifyIcon object (see "Icon format" above)aliases icon aliases, object (see "Aliases" section below)Example:
{
"prefix": "mdi",
"icons": {
"home": {
"body": "<path d=\"M10 20v-6h4v6h5v-8h3L12 3L2 12h3v8h5z\" fill=\"currentColor\"/>",
"width": 24,
"height": 24
},
"arrow-left": {
"body": "<path d=\"M20 11v2H8l5.5 5.5l-1.42 1.42L4.16 12l7.92-7.92L13.5 5.5L8 11h12z\" fill=\"currentColor\"/>",
"width": 24,
"height": 24
}
}
}
All icon properties except for body are optional and are represented by type IconifyOptional. Type IconifyJSON also extends type IconifyOptional, allowing all optional properties to be placed in root object.
If icon is missing a property, look in root object for default value. If root object does not have default value, use global default value for that property (see list of properties and default values in "Icon format" section above).
This allows to reduce duplication.
Example:
{
"prefix": "mdi",
"icons": {
"home": {
"body": "<path d=\"M10 20v-6h4v6h5v-8h3L12 3L2 12h3v8h5z\" fill=\"currentColor\"/>"
},
"arrow-left": {
"body": "<path d=\"M20 11v2H8l5.5 5.5l-1.42 1.42L4.16 12l7.92-7.92L13.5 5.5L8 11h12z\" fill=\"currentColor\"/>"
}
},
"width": 24,
"height": 24
}
In this example both icons are 24x24, so width and height have been moved to root object.
Another example:
{
"prefix": "fa-solid",
"icons": {
"arrow-left": {
"body": "<path d=\"M257.5 445.1l-22.2 22.2c-9.4 9.4-24.6 9.4-33.9 0L7 273c-9.4-9.4-9.4-24.6 0-33.9L201.4 44.7c9.4-9.4 24.6-9.4 33.9 0l22.2 22.2c9.5 9.5 9.3 25-.4 34.3L136.6 216H424c13.3 0 24 10.7 24 24v32c0 13.3-10.7 24-24 24H136.6l120.5 114.8c9.8 9.3 10 24.8.4 34.3z\" fill=\"currentColor\"/>",
"width": 448
},
"arrow-circle-left": {

},
"barcode": {
"body": "<path d=\"M0 448V64h18v384H0zm26.857-.273V64H36v383.727h-9.143zm27.143 0V64h8.857v383.727H54zm44.857 0V64h8.857v383.727h-8.857zm36 0V64h17.714v383.727h-17.714zm44.857 0V64h8.857v383.727h-8.857zm18 0V64h8.857v383.727h-8.857zm18 0V64h8.857v383.727h-8.857zm35.715 0V64h18v383.727h-18zm44.857 0V64h18v383.727h-18zm35.999 0V64h18.001v383.727h-18.001zm36.001 0V64h18.001v383.727h-18.001zm26.857 0V64h18v383.727h-18zm45.143 0V64h26.857v383.727h-26.857zm35.714 0V64h9.143v383.727H476zm18 .273V64h18v384h-18z\" fill=\"currentColor\"/>"
}
},
"width": 512,
"height": 512
}
In this example arrow-circle-left and barcode have width of 512, arrow-left has width of 448. All icons have height of 512.
In addition to icons, another important field in JSON object is aliases.
Aliases object is similar to icons object, except that instead of icon body icons reference another icon.
Each entry has same attributes as icon, except for body and has required attribute parent that contains name of parent icon. Parent icon must be included in JSON file as well as icon.
Example:
{
"prefix": "fa",
"icons": {
"automobile": {
"body": "<path d=\"M480 960q0-66-47-113t-113-47t-113 47t-47 113t47 113t113 47t113-47t47-113zm36-320h1016l-89-357q-2-8-14-17.5t-21-9.5H640q-9 0-21 9.5T605 283zm1372 320q0-66-47-113t-113-47t-113 47t-47 113t47 113t113 47t113-47t47-113zm160-96v384q0 14-9 23t-23 9h-96v128q0 80-56 136t-136 56t-136-56t-56-136v-128H512v128q0 80-56 136t-136 56t-136-56t-56-136v-128H32q-14 0-23-9t-9-23V864q0-93 65.5-158.5T224 640h28l105-419q23-94 104-157.5T640 0h768q98 0 179 63.5T1691 221l105 419h28q93 0 158.5 65.5T2048 864z\" fill=\"currentColor\"/>",
"width": 2048,
"height": 1600
}
},
"aliases": {
"car": {
"parent": "automobile"
}
}
}
In this example "car" is alias of "automobile", allowing to use same icon by multiple names.
Another example:
{
"prefix": "fa",
"icons": {
"caret-left": {
"body": "<path d=\"M576 192v896q0 26-19 45t-45 19t-45-19L19 685Q0 666 0 640t19-45l448-448q19-19 45-19t45 19t19 45z\" fill=\"currentColor\"/>",
"width": 576,
"height": 1280
}
},
"aliases": {
"caret-right": {
"parent": "caret-left",
"hFlip": true
}
}
}
In this example caret-right is alias of caret-left, but with additional hFlip attribute. It is identical to this:
{
"prefix": "fa",
"icons": {
"caret-left": {
"body": "<path d=\"M576 192v896q0 26-19 45t-45 19t-45-19L19 685Q0 666 0 640t19-45l448-448q19-19 45-19t45 19t19 45z\" fill=\"currentColor\"/>"
},
"caret-right": {
"body": "<path d=\"M576 192v896q0 26-19 45t-45 19t-45-19L19 685Q0 666 0 640t19-45l448-448q19-19 45-19t45 19t19 45z\" fill=\"currentColor\"/>",
"hFlip": true
}
},
"width": 576,
"height": 1280
}
If both icon and alias have same attribute, following rules apply:
rotate: attributes are combined. For example, icon has rotate = 1, alias has rotate = 1. Result will have rotate = 2. If rotate > 3, rotate = rotate - 4.hFlip and vFlip: attributes are combined. For example, icon has hFlip = true, alias also has hFlip = true (icon.hFlip !== alias.hFlip). Result is false. false + false = false, false + true = true, true + true = false.Example:
{
"prefix": "fa",
"icons": {
"caret-left": {
"body": "<path d=\"M576 192v896q0 26-19 45t-45 19t-45-19L19 685Q0 666 0 640t19-45l448-448q19-19 45-19t45 19t19 45z\" fill=\"currentColor\"/>",
"hFlip": true,
"width": 576,
"height": 1280
}
},
"aliases": {
"caret-left-compact": {
"parent": "caret-left",
"left": 64,
"width": 448
},
"caret-right": {
"parent": "caret-left",
"hFlip": true
}
}
}
is identical to:
{
"prefix": "fa",
"icons": {
"caret-left": {
"body": "<path d=\"M576 192v896q0 26-19 45t-45 19t-45-19L19 685Q0 666 0 640t19-45l448-448q19-19 45-19t45 19t19 45z\" fill=\"currentColor\"/>",
"hFlip": true
},
"caret-left-compact": {
"body": "<path d=\"M576 192v896q0 26-19 45t-45 19t-45-19L19 685Q0 666 0 640t19-45l448-448q19-19 45-19t45 19t19 45z\" fill=\"currentColor\"/>",
"hFlip": true, // from caret-left
"left": 64, // overwritten
"width": 448 // overwritten
},
"caret-right": {
"body": "<path d=\"M576 192v896q0 26-19 45t-45 19t-45-19L19 685Q0 666 0 640t19-45l448-448q19-19 45-19t45 19t19 45z\" fill=\"currentColor\"/>"
// hFlip = false, which is default value, so it was removed
}
},
"width": 576,
"height": 1280
}
JSON files might also contain meta data. That data is used for browsing icons, searching icons, exporting icon sets as fonts.
Meta data is combination of several types, represented as type IconifyMetaData.
Icon set information is part of meta data, it includes information about author and license.
Example:
{
"prefix": "dashicons",
"info": {
"name": "Dashicons",
"total": 304,
"author": {
"name": "WordPress",
"url": "https://github.com/WordPress/dashicons"
},
"license": {
"title": "GPL 2.0",
"spdx": "GPL-2.0-only",
"url": "http://www.gnu.org/licenses/gpl-2.0.html"
},
"version": "0.9.0",
"samples": ["shortcode", "businessperson", "editor-expand"],
"height": 20,
"category": "General",
"palette": false
},
"icons": {
// Icons here
}
}
Characters map is part of meta data, it is used for icon sets are are either imported from icon fonts or intended to be exported to icon font.
Characters map allows to store characters for export as well as searching icons by character used in icon font.
It is a simple object, where key is character code in hexadecimal form, value is icon name.
Important: each icon can have multiple characters!
Example:
{
"prefix": "fa",
"icons": {
// Icons here
},
"chars": {
"f000": "glass",
"f001": "music",
"f002": "search",
"f003": "envelope-o",
"f004": "heart",
"f005": "star"
// and so on...
}
}
Categories are part of meta data, used to allow filtering icons when showing entire icons set.
Categories list is simple object, where key is category name, value is list of icons.
Important: each icon can belong to multiple categories!
{
"prefix": "fa-solid",
"icons": {
// Icons here
},
"categories": {
"Accessibility": [
"american-sign-language-interpreting",
"assistive-listening-systems",
"audio-description",
"blind",
"braille",
"closed-captioning",
"deaf",
"low-vision",
"phone-volume",
"question-circle",
"sign-language",
"tty",
"universal-access",
"wheelchair"
],
"Alert": [
"bell",
"bell-slash",
"exclamation",
"exclamation-circle",
"exclamation-triangle",
"radiation",
"radiation-alt",
"skull-crossbones"
]
// and so on...
}
}
Themes are part of meta data, similar to categories, but using prefixes or suffixes to identify icons that belong to theme.
This is useful when icon set has variations of icons, such as "baseline-", "outline-".
Example:
{
"prefix": "ic",
"icons": {
// Icons here
},
"themes": {
"baseline": {
"title": "Baseline",
"prefix": "baseline-"
},
"outline": {
"title": "Outline",
"prefix": "outline-"
},
"round": {
"title": "Round",
"prefix": "round-"
},
"sharp": {
"title": "Sharp",
"prefix": "sharp-"
},
"twotone": {
"title": "Two-Tone",
"prefix": "twotone-"
}
}
}
Each theme can have one of attributes: prefix or suffix. Prefix must end with -, suffix must start with -.
In example above, all icons that start with "baseline-", such as "baseline-home", are considered part of "Baseline" theme.
For example of full JSON files that include meta data, look in JSON files in @iconify/json package or browse it at GitHub: https://github.com/iconify/collections-json
For example of individual icons, look in JavaScript files in NPM packages such as @iconify/icons-mdi.
This repository is intended to be used with any Iconify packages.
At the moment of writing, there are multiple Iconify packages that are written without TypeScript. At the beginning of 2020 plan is to rewrite all of them with TypeScript to make sure data is consistent and avoid duplication, this package will be used for sharing types between Iconify packages.
