Status

jSanity was just recently revived from two years of cold storage. Only very minimal changes have been made so far since the code was originally developed.

Demo / Benchmark pages

Todo

• Support for more elements and attributes.
• setImmediate didn't gain traction. Switch to an alternative approach.
  • For now jSanity uses a polyfill.
• Update / document the demo & benchmark pages
• Unit tests
• Remove requirement for jQuery (?)
• Better solution for STYLE elements
• Integration with one or more javascript frameworks
• Experimental override for default sanitization in various web platforms
• Leverage newer features of the web platform (Shadow DOM, etc.)

Special thanks for making jSanity a reality:

• Ben Livshits
• Gareth Heyes
• Loris D'Antoni
• Mario Heiderich
• Matt Thomlinson
