Embed extension options

Properties

encoding?

optional encoding?: VizelMarkdownLossyEncodingMode;

Defined in: packages/core/src/extensions/embed.ts:87

Markdown encoding mode.

• "default" emits the lossy form [title || url](url). Metadata such as type and provider is lost on round-trip.
• "metadata-comment" emits the lossless form [title || url](url)<!-- vizel:embed type="..." provider="..." --> so the metadata survives round-trips through plain markdown.

Default

"default"

fetchEmbedData?

optional fetchEmbedData?: VizelFetchEmbedDataFn;

Defined in: packages/core/src/extensions/embed.ts:59

By default, uses createVizelDefaultFetchEmbedData() which fetches oEmbed data for CORS-enabled providers (YouTube, Vimeo, Spotify, etc.)

For full OGP/metadata support, provide a custom function that uses a server-side proxy to fetch page metadata.
