Get all Bootstrap Icons to use in your powerapps.

Summary

This PowerShell script downloads the latest Bootstrap icons from twbs@github, creates a JSON file with the complete list of SVG icons you can use.

Use it in PowerApps

Copy the content from BootstrapIcons.json and add it to App.OnStart (See also Note about Named Formulas below sample). This will give you access to all the Bootstap Icons in your app.

To use an Icon, add an Image and the following code to the image property: Change the for any name found in the Bootstrap icons list, ex. alphabet-uppercase.

 data:image/svg+xml;utf8, " & EncodeUrl(" & LookUp(colBSIcons; IconName = <ICON NAME>).IconData)

Note about Named Formulas

A new feature in Power Apps allows for a better implementation, namely Named Formulas. At current this app is not designed for this function, but a future version is planned for handling all this in a better way.
