Here’s an online demo.

Installation

npm

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

Yarn

yarn add --dev @babel/plugin-proposal-unicode-property-regex

pnpm

pnpm add --save-dev @babel/plugin-proposal-unicode-property-regex

Usage

With a configuration file (Recommended)

babel.config.json

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

Via CLI

Shell

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

Via Node.js API

JavaScript

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

To transpile to ES6/ES2015:

JavaScript

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

Options

• useUnicodeFlag (defaults to true)

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.
