## README

# 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.
