Simple helper to perform basic preparations on strings to use them in Regular Expressions.
$ npm install --save @konfirm/expressionist
const Expressionist = require('@konfirm/expressionist');
Replace potential capture groups with non-capture groups, while leaving existing non-capture groups (
(?:...)) and lookaheads (positive (
(?=...)) and negative (
const ungrouped = Expressionist.ungroup('(hello(world))'); console.log(ungrouped); // '(?:hello(?:world))
Escape all characters with a special meaning in Regular Expressions so that these can be matched exactly
const escaped = Expressionist.escape('email@example.com'); console.log(escaped); // 'john\.doe\+label@example\.com'
