HighlightAuto supports languageNames

You can restrict language auto-detection to a subset using the languageNames prop. This can improve performance and accuracy.

<script>
  import { HighlightAuto } from "svelte-highlight";

  const code = "const x = 42;";
</script>

<HighlightAuto {code} languageNames={["javascript", "typescript"]} />

LanguageName utility type

Use the LanguageName to strongly type the language names included by highlight.js.

import type { LanguageName } from "svelte-highlight";
