LiveFlow.Export (LiveFlow v0.3.2)

Server-side SVG rendering of a flow, without a browser.

Useful to generate thumbnails, previews or downloads from a LiveView or a background job. Nodes are drawn as rounded boxes with their label (data.label, data.title or the node id); edges use the same path algorithms as the client. Custom node content (function components) is not rendered: use the client-side exportSVG/exportPNG for pixel-perfect output.

Examples

svg = LiveFlow.Export.to_svg(flow, theme: :dark)
File.write!("flow.svg", svg)
