heroicons-tag-helper

ASP.NET tag helper for adding Heroicons to your razor views.

Installation

Note

This package's version is aligned with the heroicons NPM package so you always know which version you're using.

dotnet add package HeroiconsTagHelper

CI builds can be downloaded from the packages page or the GitHub feed. They're also available as build artifacts on every PR.

Setup

In your _ViewImports.cshtml add:

@addTagHelper *, HeroiconsTagHelper

In your Startup.cs add:

public void ConfigureServices(IServiceCollection services)
{
    services.AddHeroicons(Configuration);
}

In your appsettings.json add:

{
  "Heroicons": {
    "IncludeComments": true,
    "SetAccessibilityAttributes": true,
    "SetFocusableAttribute": true
  }
}

Settings

Name	Default Value	Description
IncludeComments	false	Add an html comment before the svg tag with the style and name of the icon to help make development/debugging easier.
SetAccessibilityAttributes	false	Adds various accessibility attributes based on the default state of the tag.
SetFocusableAttribute	false	Adds the focusable attribute set to false to prevent the icon from receiving focus in Internet Explorer and Edge Legacy.

SetAccessibilityAttributes

If aria-label or aria-labeledby are set then the icon is being used as an image so role="img" will be added to the svg tag, otherwise aria-hidden="true" will be added.

Note: If the element already contains an aria-hidden or role attribute then it will not be modified.

Usage

There are two versions of the tag helper which are used to pick between the outline and solid icon styles.

<heroicon-outline icon="Sun" class="h-6 w-6 text-orange-500" />

will output

<svg class="h-6 w-6 text-orange-500" fill="none" stroke="currentColor" viewBox="0 0 24 24">
    <path stroke-linecap="round" stroke-linejoin="round" stroke-width="2" d="M12 3v1m0 16v1m9-9h-1M4 12H3m15.364 6.364l-.707-.707M6.343 6.343l-.707-.707m12.728 0l-.707.707M6.343 17.657l-.707.707M16 12a4 4 0 11-8 0 4 4 0 018 0z" />

<heroicon-solid icon="Sun" class="h-6 w-6 text-orange-500" />
