Using FontAwesome with Rails was really easy with
font-awesome-rails gem. It also had really nice helpers. Thing is this gem depends on Sprokets. I wanted to try the shiny but very light Propshaft to be inline with modern Rails.
I had 2 options:
- Copy the SVG codes individual icons as needed and use them as part of view. (Easy)
- Consigure FontAwesome as part of build process. (Some work, Easy to update)
I went for 2nd route, mainly because I didn't want to store bunch of SVG codes in my main codebase.
The following solution works on a Rails 7 app configured with
First of all, let's install
sass to package that.
yarn add sass yarn add @fortawesome/fontawesome-free
I used v6, but if you need v5, specify the version.
Next, create a entrypoint for sass, call it
$fa-font-path: "./webfonts"; @import "@fortawesome/fontawesome-free/scss/regular"; @import "@fortawesome/fontawesome-free/scss/brands"; @import "@fortawesome/fontawesome-free/scss/solid"; @import "@fortawesome/fontawesome-free/scss/fontawesome";
You may comment out any of
solid, if you're not using.
The main magic here is the line
$fa-font-path: "./webfonts";. Without this line, propshaft will fail to find the fonts assets.
Now let's add a task for yarn in
package.json to build the files, add the following the
"build:css:fontawesome": "cp -r ./node_modules/@fortawesome/fontawesome-free/webfonts ./app/assets/builds && sass ./app/assets/stylesheets/fontawesome.scss ./app/assets/builds/fontawesome.css --no-source-map --load-path=node_modules --quiet"
Final step, include it in the layout (
application.html.erb or anywhere else):
<%= stylesheet_link_tag "fontawesome", "data-turbo-track": "reload" %>
Now you can build the assets with the following command, and propshaft will heapily serve it:
One extra step would be adding the command as part of
bin/dev. You can simple add the following line as part of your
fa: yarn build:css:fontawesome --watch
Now, whenever you would run
bin/dev, fontawesome will be compiled for you.
For me, this works. If you have any nicer solution, please let me know in the comments below.
Note: If you already have a SASS setup, you may want to move the content of
app/assets/stylesheets/fontawesome.scss to your
application.scss or your other entrypoint file, instead of creating another entrypoint. That should work fine as well.
