Pretext is a new JavaScript/TypeScript library for multiline text measurement and layout that avoids expensive DOM reflows by implementing its own text measurement logic. It uses the browser's font engine as ground truth and supports rendering to DOM, Canvas, SVG with server-side support coming soon. The library aims to provide fast, accurate text layout while supporting a wide range of languages.
Background
Text measurement and layout in web applications traditionally relies on DOM APIs that trigger expensive layout reflows, which can significantly impact performance especially in dynamic applications.
