Unicode Escape Plugin for Webpack

@dapplets/unicode-escape-webpack-plugin is a simple Webpack plugin that escapes all Unicode characters in your JavaScript files. This is useful for ensuring compatibility with environments that do not support certain Unicode characters natively.

Features

• Escapes all Unicode characters (\u007f and above) in .js files.
• Configurable to target specific file types or extensions.
• Lightweight and easy to use.

Installation

Install the package via npm:

npm install -D @dapplets/unicode-escape-webpack-plugin

Usage

Add the plugin to your Webpack configuration file:

Example: Basic Configuration

javascript

Copy code

const UnicodeEscapePlugin = require("@dapplets/unicode-escape-webpack-plugin");

module.exports = {
  mode: "production", // or 'development'
  entry: "./src/index.js",
  output: {
    filename: "bundle.js",
    path: __dirname + "/dist",
  },
  plugins: [
    new UnicodeEscapePlugin({
      test: /\.js$/, // Process only `.js` files (default)
    }),
  ],
};

Example: Custom File Types

You can customize the test option to target other file types:

javascript

Copy code

new UnicodeEscapePlugin({
  test: /\.(js|jsx|ts|tsx)$/, // Escape Unicode in JavaScript and TypeScript files
});

How It Works

The plugin hooks into Webpack's build process and processes the specified files during the emit phase. It escapes Unicode characters using the \uXXXX format for all characters with a Unicode code point of \u007f or higher.

Input Example

javascript

Copy code

const example = "Unicode: é, ☃, 🐱";

Output Example

javascript

Copy code

const example = "Unicode: \\u00e9, \\u2603, \\ud83d\\udc31";

Options

Option	Type	Default	Description
test	RegExp	/\.js$/	A regular expression to match files for processing.
