Regex reference

Each regular expression listed below is paired with an embeddable string named xxxString. E.g., rgbRE is paired with rgbREString. Each RE will only match strings that are the given type and nothing else. I.e., the RE begins with '^' and ends with '$'. The xxxREString can be used for partial matches, matchAlls, and used as part of larger expressions. E.g., to find all unique CSS RGB colors used in a style sheet, you might do something like:

import { rgbREString } from '@liquid-labs/regex-repo'

const allColors = cssContent
  .matchAll(new RegExp(`[ :](${rgbREString})[; }]`, 'g'))
  .map((match) => match[1]) // extract the capture group
  .filter((v, i, arr) => i === arr.indexOf(v)) // filter non-unique items
  .sort()
