Dropflow is a CSS layout engine written in TypeScript that implements foundational CSS standards (inlines, blocks, floats, positioning) with high-quality international text layout. It can render to canvas in the browser or generate PDFs and images on the backend via Node and node-canvas.

Use cases

• generate pdfs from html and css on the server
• render rich wrapped text to a canvas in the browser
• lay out bidirectional and rtl text
• render multilingual text with font fallbacks
• convert html with css styles into images with node-canvas

When to choose

• you need standards-based CSS block/inline/float layout outside the browser
• you need high-quality text shaping, bidi, and grapheme-level font fallback
• you want to render HTML/CSS content to canvas or PDF in Node

When to avoid

• you need flexbox or grid layout, which are not supported
• you need a full browser rendering engine with JavaScript interaction
• you need a mature production engine like Blink or WebKit
