cheerio-select NPM version Build Status Downloads Coverage

CSS selector engine supporting jQuery selectors, based on css-select.

Supports all jQuery positional pseudo-selectors:

  • :first
  • :last
  • :eq
  • :nth
  • :gt
  • :lt
  • :even
  • :odd
  • :not(:positional), where :positional is any of the above.

This library is a thin wrapper around css-select. Only use this module if you will actually use jQuery positional selectors.
