- # unicode-property-aliases-ecmascript [](https://travis-ci.org/mathiasbynens/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.
