+# unicode-property-aliases-ecmascript [![unicode-property-aliases-ecmascript on npm](https://img.shields.io/npm/v/unicode-property-aliases-ecmascript)](https://www.npmjs.com/package/unicode-property-aliases-ecmascript)
+
+_unicode-property-aliases-ecmascript_ offers Unicode property alias mappings in an easy-to-consume JavaScript format. It only contains the Unicode property names that are supported in [ECMAScript RegExp property escapes](https://github.com/tc39/proposal-regexp-unicode-property-escapes).
+
+It’s based on Unicode’s `PropertyAliases.txt`.
+
+## Installation
+
+To use _unicode-property-aliases-ecmascript_ programmatically, install it as a dependency via [npm](https://www.npmjs.com/):
+
+```bash
+$ npm install unicode-property-aliases-ecmascript
+```
+
+Then, `require` it:
+
+```js
+const propertyAliases = require('unicode-property-aliases-ecmascript');
+```
+
+## Usage
+
+This module exports a `Map` object. The most common usage is to convert a property alias to its canonical form:
+
+```js
+propertyAliases.get('scx');
+// → 'Script_Extensions'
+```
+
+## For maintainers
+
+### How to publish a new release
+
+1. On the `main` branch, bump the version number in `package.json`:
+
+   ```sh
+   npm version patch -m 'Release v%s'
+   ```
+
+   Instead of `patch`, use `minor` or `major` [as needed](https://semver.org/).
+
+   Note that this produces a Git commit + tag.
+
+1. Push the release commit and tag:
+
+   ```sh
+   git push && git push --tags
+   ```
+
+   Our CI then automatically publishes the new release to npm.
