@babel/plugin-proposal-unicode-property-regex

Compile Unicode property escapes (\p{…} and \P{…}) in Unicode regular expressions to ES5 or ES6 that works in today’s environments.

Note: the Unicode property escape syntax is non-standard and may or may not reflect what eventually gets specified.

Installation

npm install @babel/plugin-proposal-unicode-property-regex

.babelrc

{
  "plugins": ["@babel/proposal-unicode-property-regex"]
}

babel --plugins @babel/@babel/proposal-unicode-property-regex script.js

require("@babel/core").transform(code, {
  "plugins": ["@babel/proposal-unicode-property-regex"]
});

To transpile to ES6/ES2015:

require("@babel/core").transform(code, {
  "plugins": [
    ["@babel/proposal-unicode-property-regex", { "useUnicodeFlag": false }]
  ]
});

When disabled with false, the transform converts Unicode regexes to non-Unicode regexes for wider support, removing the u flag. See https://github.com/mathiasbynens/regexpu-core#useunicodeflag-default-false for more information.
