# 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. ## Author | [](https://twitter.com/mathias "Follow @mathias on Twitter") | |---| | [Mathias Bynens](https://mathiasbynens.be/) | ## License _unicode-property-aliases-ecmascript_ is available under the [MIT](https://mths.be/mit) license.
