Rangy is a cross-browser JavaScript library for working with DOM ranges and text selections. It normalizes browser inconsistencies and provides modules for saving/restoring selections, highlighting, and caret manipulation.

Use cases

  • manipulate text selections in the browser consistently across browsers
  • save and restore user text selections
  • build text highlighting or annotation features
  • get or set the caret position in contenteditable elements
  • work with DOM ranges without writing browser-specific code

When to choose

  • you need reliable cross-browser selection and range handling in a web app
  • you're building rich text editors, highlighters, or annotation tools in vanilla JS
  • you need to serialize and restore selections across page updates

When to avoid

  • you're using a modern framework with built-in selection utilities and only target evergreen browsers
  • you need server-side DOM manipulation (it's browser-focused)
  • you want an actively developed project with ongoing feature work
