Icon

Inline SVG icons from Lucide, rendered on the server.

An interactive page: C# runs over a Blazor Server connection.

Renders an icon as inline SVG on the server: no font or script to load, works on static pages, and follows the text color and size around it.

Usage

razor

<Icon Name="Lucide.House" />
<Icon Name="Lucide.TriangleAlert" Size="IconSize.Lg" Color="Color.WarningText" Label="Warning" />
<Icon Role="IconRole.Close" />

Beside text

Use Icon with a Name such as Lucide.House: it's sized in em and takes the text color, so it matches the text it sits in.

Semantic roles

Use Role to ask for a purpose rather than a drawing, so one icon set can change every icon the library draws.

Roles.razor

@* The library's own components ask for a role, so one IconSet changes every icon they draw. *@
<Grid Columns="new() { Base = 2, Sm = 3, Xl = 4 }" Gap="3" Grow>
    @foreach (var role in Enum.GetValues<IconRole>())
    {
        <Row Gap="2" Align="Align.Center">

            <TextBlock As="span" Size="TextSize.Sm">@role</TextBlock>
        </Row>
    }
</Grid>

Brand logos

Use Brands for the logos sites link to most, drawn to match Lucide.

Logos.razor

@* Brand logos drawn to match Lucide. Alone, as in an icon-only link, a logo needs a name. *@

Mode support

What works in each mode, Icon
Feature	Off	Static	Live
Everything	Yes	Yes	Yes

Off: JavaScript disabled. Static: a static SSR page with IzzyBlazor's script. Live: an interactive page (Server, WebAssembly or Auto).

Accessibility

Without a Label it's decorative: aria-hidden="true", which is right when visible text sits next to it.
With a Label it's role="img" named by the label; give one to an icon that stands alone and means something.
It never takes focus. An action shown only as an icon needs a button with a name: use IconButton.
With reduced motion set, Spin slows down rather than stops, since the spin says "still working".
