Iconify Icon for Solid

Iconify Icon web component is a wrapper for iconify-icon package, which provides SolidJS component and typings.

For more information about Iconify project visit https://iconify.design/.

For documentation visit Iconify Icon web component documentation.

Installation

If you are using NPM:

npm install --save-dev @iconify-icon/solid

If you are using Yarn:

yarn add --dev @iconify-icon/solid

Usage

Install @iconify-icon/solid and import Icon from it:

import { Icon } from '@iconify-icon/solid';

Then use Icon component with icon name or data as "icon" parameter:

<Icon icon="mdi-light:home" />

Component will automatically retrieve data for "mdi-light:home" from Iconify API and render it. There are over 100,000 icons available on Iconify API from various free and open source icon sets, including all the most popular icon sets.

Offline Usage

Retrieving icon data from Iconify API requires visitor to be online. What if you want to use component offline or on local network?

If you want to use icon component without relying on public Iconify API, there are several options:

1. You can import icon data from Iconify Icons packages.
2. You can create custom icon bundles (more efficient, but requires more coding).
3. You can host your own Iconify API instead of relying on third party service.

See offline use documentation or Iconify API documentation.

Icon Names

Icon name is a string. Few examples:

• @api-provider:icon-set-prefix:icon-name
• mdi-light:home (in this example API provider is empty, so it is skipped)

It has 3 parts, separated by ":":

• provider points to API source. Starts with "@", can be empty (empty value is used for public Iconify API).
• prefix is name of icon set.
• name is name of icon.

See icon names documentation for more detailed explanation.

Using icon data

Instead of icon name, you can pass icon data to component:

import { Icon } from '@iconify-icon/solid';
import home from '@iconify-icons/mdi-light/home';

function renderHomeIcon() {
	return <Icon icon={home} />;
}

See icon packages documentation for more details.

Next.js notice

Example above might fail with Next.js. This is because Next.js uses outdated packaging software that does not support ES modules. But do not worry, there is a simple solution: switch to CommonJS icon packages.

To switch to CommonJS package, replace this line in example above:

import home from '@iconify-icons/mdi-light/home';

with

import home from '@iconify/icons-mdi-light/home';

All icons are available as ES modules for modern bundler and as CommonJS modules for outdated bundlers. ES modules use format @iconify-icons/{prefix}, CommonJS modules use @iconify/icons-{prefix}.

For more details, see icon packages documentation.

Icon component properties

icon property is mandatory. It tells component what icon to render. The value can be a string containing the icon name or an object containing the icon data.

The icon component has the following optional properties:

• inline. Changes icon behaviour to match icon fonts. If set to true, it adds vertical alignment to icon to render it below text baseline, so it fits nicely in text.
• width and height. Icon dimensions. The default values are "1em" for both. See "Dimensions" section below.
• color. Icon colour. This is the same as setting colour in style. See "Icon colour" section below.
• flip. Flip icon horizontally and/or vertically. See "Transformations" section below.
• rotate. Rotate icon by 90, 180 or 270 degrees. See "Transformations" section below.

Other properties and events

In addition to the properties mentioned above, the icon component accepts any other properties and events.

Dimensions

By default, icon height is "1em". With is dynamic, calculated using the icon's width to height ratio. This makes it easy to change icon size by changing font-size in the stylesheet, just like icon fonts.

There are several ways to change icon dimensions:

• Setting font-size in style (or fontSize if you are using inline style).
• Setting width and/or height property.

Values for width and height can be numbers or strings.

If you set only one dimension, another dimension will be calculated using the icon's width to height ratio. For example, if the icon size is 16 x 24, you set the height to 48, the width will be set to 32. Calculations work not only with numbers, but also with string values.

Dimensions as numbers

You can use numbers for width and height.

<Icon icon={homeIcon} height={24} />

<Icon icon="mdi-light:home" width={16} height={16} />

Number values are treated as pixels. That means in examples above, values are identical to "24px" and "16px".

Dimensions as strings without units

If you use strings without units, they are treated the same as numbers in an example above.

<Icon icon={homeIcon} height="24" />

<Icon icon="mdi-light:home" width="16" height={'16'} />

Dimensions as strings with units

You can use units in width and height values:

<Icon icon="mdi-light:home" height="2em" />

Be careful when using calc, view port based units or percentages. In SVG element they might not behave the way you expect them to behave and when using such units, you should consider settings both width and height.

Dimensions as 'auto'

Keyword "auto" sets dimensions to the icon's viewBox dimensions. For example, for 24 x 24 icon using height="auto" sets height to 24 pixels.

<Icon icon="mdi-light:home" height="auto" />

Icon colour

There are two types of icons: icons that do not have a palette and icons that do have a palette.

Icons that do have a palette, such as emojis, cannot be customised. Setting colour to such icons will not change anything.

Icons that do not have a palette can be customised. By default, colour is set to "currentColor", which means the icon's colour matches text colour. To change the colour you need to change text color.

Examples:

<Icon icon="eva:alert-triangle-fill" style={{color: 'red'}} />
<Icon icon="eva:alert-triangle-fill" style={{color: '#f00'}} />

Using stylesheet:

<Icon icon="eva:alert-triangle-fill" className="red-icon" />

.red-icon {
	color: red;
}

Transformations

You can rotate and flip the icon.

This might seem redundant because icon can also be rotated and flipped using CSS transformations. So why do transformation properties exist? Because it is a different type of transformation.

• CSS transformations transform the entire icon.
• Icon transformations transform the contents of the icon.

If you have a square icon, this makes no difference. However, if you have an icon that has different width and height values, it makes a huge difference.

Rotating 16x24 icon by 90 degrees results in:

• CSS transformation keeps 16x24 bounding box, which might cause the icon to overlap text around it.
• Icon transformation changes bounding box to 24x16, rotating content inside an icon.

See icon transformations documentation for more details.

Flipping an icon

You can flip an icon horizontally and/or vertically by setting flip property.

Examples:

Flip an icon horizontally:

<Icon icon="eva:alert-triangle-fill" flip="horizontal" />

Flip an icon vertically:

<Icon icon="eva:alert-triangle-fill" flip="vertical" />

Flip an icon horizontally and vertically (the same as 180 degrees rotation):

<Icon icon="eva:alert-triangle-fill" flip="horizontal,vertical" />

Rotating an icon

An icon can be rotated by 90, 180 and 270 degrees. Only contents of the icon are rotated.

To rotate an icon, use rotate property. Value can be a string (degrees or percentages) or a number.

Number values are 1 for 90 degrees, 2 for 180 degrees, 3 for 270 degrees.

Examples of 90 degrees rotation:

<Icon icon="eva:alert-triangle-fill" rotate={1} />
<Icon icon="eva:alert-triangle-fill" rotate="90deg" />
<Icon icon="eva:alert-triangle-fill" rotate="25%" />
