@humanspeak/svelte-markdown/dist/index.js

Markdown and HTML renderer for Svelte 5 — built for rendering streaming AI agent output from Claude Code, ChatGPT, and agentic workflows. XSS-safe defaults, streaming-aware sanitization, token caching, TypeScript types, and Svelte 5 runes.

/**
 * Public API for `@humanspeak/svelte-markdown`.
 *
 * This module re-exports every symbol that consumers of the package can
 * import.  Exports are organized into the following groups:
 *
 * - **Default export** — the main `SvelteMarkdown` component
 * - **Component helpers** — `Html`, `Unsupported`, and `UnsupportedHTML`
 * - **Filter utilities** — allow/deny helpers for HTML tags and renderers
 * - **Constants** — `defaultRenderers`, `rendererKeys`, `htmlRendererKeys`
 * - **Cache utilities** — `MemoryCache`, `TokenCache`, `tokenCache`
 * - **Types** — `HtmlRenderers`, `Renderers`, `RendererComponent`,
 *   `SvelteMarkdownProps`, `SvelteMarkdownOptions`, `Token`, `TokensList`
 *
 * @see {@link https://markdown.svelte.page} — documentation site
