We’ve built a widget library for version 5.5.0 of Font Awesome icons.
Please note that version 5 differs not only in icons, but in formatting and categories, so if you have version 4.7 of Font Awesome installed, make sure to install version 5, as the font files are entirely separate. It’s also worth noting that Font Awesome has updated their toolkit a few times since this original post. So, different versions of their CSS and font files could be floating around, which may be incompatible with the specific widget library provided in the original post. Using consistent versions across these three components (RPLIB, FA font file, and CSS link) would be ideal. You can find the most recent version of Font Awesome assets below.
And here are the steps:
1. Download and install version 5.5.0 version of the Font Awesome 5 font file.
https://use.fontawesome.com/releases/v5.5.0/fontawesome-free-5.5.0-desktop.zip
Open the “otfs” folder, and install the three “Font Awesome 5 Brands-Regular-400.otf”, “Font Awesome 5 Free-Regular-400.otf”, and “Font Awesome 5 Free-Solid-900.otf” font files.
2. Restart Axure RP.
If Axure RP is open, shut it down completely and re-open it. This will allow you to choose “Font Awesome 5 Free/Brands” from the font droplist and see the correct icon in the editor.
3. Go to “Publish > Generate HTML Files” and add the Font Awesome CSS link in the “Web Fonts” tab:
https://use.fontawesome.com/releases/v5.5.0/css/all.css
4. Download the Axure Font Awesome V5.5.0 widget library, and load it into Axure RP via hamburger menu > “Load Library”.
FontAwesomeV5.5.0.rplib (10.2 MB)
Alternatively, you can copy & paste the icons from the FontAwesome official cheat sheet.
5. Drag and drop Font Awesome widgets from this library.
Note: Version 5 of Font Awesome icons are adjusted using widget size and fill color.
