Pretext is a pure JavaScript/TypeScript library for fast, accurate multiline text measurement and layout without triggering DOM reflow. It implements its own text measurement logic using the browser's canvas font engine, providing precise paragraph height calculation, line segmentation, and bi-directional (bidi) text support across all languages and emoji. It offers two main use-case APIs: a simple prepare/layout pair for height measurement only, and a richer prepareWithSegments set for manual line-by-line layout enabling rendering to Canvas, SVG, WebGL, or server-side contexts. An experimental inline-flow sidecar handles mixed inline runs with atomic items and boundary whitespace collapse.
