elt-fa v0.7.0
Use font-awesome with elt without hassle
npm install elt-faThis library allows you to use fontawesome with elt easily.
While you can use font-awesome with its icon font packs (ttf/woff/...) and <i> tags, you end up having to download the whole font
everytime you use it, even if using just a small subset. Also, icon fonts are not that great (https://www.lambdatest.com/blog/its-2019-lets-end-the-debate-on-icon-fonts-vs-svg-icons/ or https://cloudfour.com/thinks/seriously-dont-use-icon-fonts/).
elt-fa instead goes the svg route ; when installing it, it will get all the .svg files in @fortawesome/fontawesome-free or @fortawesome/fontawesome-pro if you are a subscriber and compile them into .tsx files ready to be imported in your project.
Icon styles are used with suffixes for individual icons (-regular, -light, -duotone or -solid). You can use the regular icon name without suffix, in which case it will use whichever version was imported last.
It exports two ways of using icons ; I(), which can take an o.RO<string> and returns a dynamic icon that may change, or <I name='...'> which looks more like tsx code and makes it easier to assign classes, but which uses a static icon name.
There is no need to declare CSS or import a file, elt-fa injects its own style node at the end of <head>.
You need to import all the icons you use one by one. If you don't, then the icon will not be recognized and this will result in a compilation error, which is what we actually want.
NOTE : You MUST add yourself a dependency of @fortawesome/fontawesome-pro in your project before installing elt-fa for it to find the pro icons.
When using duotone icons, use the classes .fa-primary and .fa-secondary in your CSS to style the icons. elt-fa does not define anything special about these classes except the fact that their fill css property uses currentcolor. Font awesome defines an opacity on the secondary, but this was discarded to keep flexibility.
Do not hesitate to do something like this in your css.
.fa-secondary {
opacity: 0.4; /* original value */

import { I } from 'elt-fa'
import 'elt-fa/power-off-duotone'
import 'elt-fa/user-solid'
import 'elt-fa/search-duotone'
import 'elt-fa/search-solid'
document.body.appendChild(<div>
{/* Pick your poison. */}
{I('power-off')}
{I('power-off-duotone')}
{I('power-off', { class: 'some-class' })} {/* I accepts classic arguments for SVGSVGElement */}
{I('not-imported')} {/* compile error */}
{I('user', svg_node => { /* you can use decorators also if needed */ })}
<I name='power-off' class='some-class'/> {/* classic style is also supported */}
<I name='search'>
<path d='M40 10 L230 118'> {/* children are appended at the end of the svg */}
{node => { /* decorators are also usable with this form */ }}
</I>
</div>)
