Iconify for Ember is not yet another icon component! There are many of them already.
What you get with other components:
Iconify icon component is nothing like that. Component does not include any icon data, it is not tied to any specific icon set. Instead, all data is retrieved from public API on demand.
That means:
For more information about Iconify project visit https://iconify.design/.
For extended documentation visit Iconify for Ember documentation.
If you are using NPM:
npm install --save-dev @iconify/ember
If you are using Yarn:
yarn add --dev @iconify/ember
Install @iconify/ember then use IconifyIcon component in template with icon name or data as "icon" parameter:
<IconifyIcon @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.
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:
See Iconify for Ember offline use documentation or Iconify API documentation.
Icon name is a string. Few examples:
@api-provider:icon-set-prefix:icon-namemdi-light:home (in this example API provider is empty, so it is skipped)It has 3 parts, separated by ":":
See Iconify for Ember icon names documentation for more detailed explanation.
Instead of icon name, you can pass icon data to component:
<IconifyIcon @icon={{chartIcon}} @height='24' />
// Import icon
import areaChartOutlined from '@iconify-icons/ant-design/area-chart-outlined';
// Create property for class, so icon data could be accessed in template as {{chartIcon}}
export default class IconDemoComponent extends Component {
chartIcon = areaChartOutlined;
}
See icon packages documentation for more details.
Icons have 2 modes: inline and block. Difference between modes is vertical-align that is added to inline icons.
Inline icons are aligned slightly below baseline, so they look centred compared to text, like glyph fonts.
Block icons do not have alignment, like images, which aligns them to baseline by default.
Alignment option was added to make icons look like continuation of text, behaving like glyph fonts. This should make migration from glyph fonts easier.
To toggle between block and inline modes, you can use boolean inline property:
<div>
<p>
Block:
<IconifyIcon @icon='line-md:image-twotone' />
<IconifyIcon @icon='mdi:account-box-outline' />
</p>
<p>
Inline:
<IconifyIcon @icon='line-md:image-twotone' @inline={{true}} />
<IconifyIcon @icon='mdi:account-box-outline' @inline={{true}} />
</p>
</div>
Visual example to show the difference between inline and block modes:
icon property is mandatory. It tells component what icon to render. If the property value is invalid, the component will render an empty icon. The value can be a string containing the icon name (icon must be registered before use by calling addIcon or addCollection, see instructions above) or an object containing the icon data.
Make sure you add @ before all property names because those are component properties, not element properties.
The icon component has the following optional properties:
inline. Changes icon behaviour to match icon fonts. See "Inline icon" section below.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, hFlip, vFlip. Flip icon horizontally and/or vertically. See "Transformations" section below.rotate. Rotate icon by 90, 180 or 270 degrees. See "Transformations" section below.align, vAlign, hAlign, slice. Icon alignment. See "Alignment" section below.onLoad. Callback function that is called when icon data has been loaded. See "onLoad" section below.You can pass any other properties as element properties (without @ before name), they will be passed to SVG element.
By default, icon height is "1em". With is dynamic, calculated using the icon's width to height ratio.
There are several ways to change icon dimensions:
font-size in style.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.
You can use numbers for width and height.
<IconifyIcon @icon='mdi-light:home' @height={{24}} />
<IconifyIcon @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".
If you use strings without units, they are treated the same as numbers in an example above.
<IconifyIcon @icon='mdi-light:home' @height='24' />
<IconifyIcon @icon='mdi-light:home' @width='16' @height='16' />
You can use units in width and height values:
<IconifyIcon @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.
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.
<IconifyIcon @icon='mdi-light:home' @height='auto' />
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 can:
color style or use stylesheet to target icon. If you are using the stylesheet, target svg element.color property.Examples:
Using color property:
<IconifyIcon @icon='eva:alert-triangle-fill' @color='red' />
<IconifyIcon @icon='eva:alert-triangle-fill' @color='#f00' />
Using inline style:
<IconifyIcon @icon='eva:alert-triangle-fill' style='color: red;' />
Using stylesheet:
<IconifyIcon @icon='eva:alert-triangle-fill' class='red-icon' />
.red-icon {
color: red;
}
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.
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:
See icon transformations documentation for more details.
There are several properties available to flip an icon:
hFlip: boolean property, flips icon horizontally.vFlip: boolean property, flips icon vertically.flip: shorthand string property, can flip icon horizontally and/or vertically.Examples:
Flip an icon horizontally:
<IconifyIcon @icon='eva:alert-triangle-fill' @hFlip={{true}} />
<IconifyIcon @icon='eva:alert-triangle-fill' @flip='horizontal' />
Flip an icon vertically:
<IconifyIcon @icon='eva:alert-triangle-fill' @vFlip={{true}} />
<IconifyIcon @icon='eva:alert-triangle-fill' @flip='vertical' />
Flip an icon horizontally and vertically (the same as 180 degrees rotation):
<IconifyIcon @icon='eva:alert-triangle-fill' @hFlip={{true}} @vFlip={{true}} />
<IconifyIcon @icon='eva:alert-triangle-fill' @flip='horizontal,vertical' />
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:
<IconifyIcon @icon='eva:alert-triangle-fill' @rotate={{1}} />
<IconifyIcon @icon='eva:alert-triangle-fill' @rotate='90deg' />
<IconifyIcon @icon='eva:alert-triangle-fill' @rotate='25%' />
onLoad property is an optional callback function. It is called when icon data has been loaded.
It is not an event, such as onClick event for links, it is a simple callback function.
When onLoad is called:
onLoad is not called.onLoad is called on first render.onLoad is called on first re-render after icon data is retrieved from API.What is the purpose of onLoad? To let you know when Icon component renders an icon and when it does not render anything. This allows you to do things like adding class name for parent element, such as "container--with-icon" that modify layout if icon is being displayed.
