# unicode-property-value-aliases [](https://www.npmjs.com/package/unicode-property-value-aliases)
_unicode-property-value-aliases_ offers the Unicode property value alias mappings in an easy-to-consume JavaScript format.
It’s based on Unicode’s `PropertyValueAliases.txt`.
For the subset used by Unicode RegExp property escapes in ECMAScript, [see _unicode-property-value-aliases-ecmascript_](https://github.com/mathiasbynens/unicode-property-value-aliases-ecmascript).
## Installation
To use _unicode-property-value-aliases_ programmatically, install it as a dependency via [npm](https://www.npmjs.com/):
```bash
$ npm install unicode-property-value-aliases
```
Then, `require` it:
```js
const propertyValueAliases = require('unicode-property-value-aliases');
```
## Usage
This module exports a `Map` object of which the keys are canonical property names and the values are `Map`s from property value aliases to canonical property value names. The most common usage is to convert a property value alias to its canonical form:
```js
propertyValueAliases.get(property).get(propertyValue)
```
Examples:
```js
propertyValueAliases.get('Bidi_Class').get('AL')
// → 'Arabic_Letter'
propertyValueAliases.get('Block').get('Alphabetic_PF')
// → 'Alphabetic_Presentation_Forms'
propertyValueAliases.get('Canonical_Combining_Class').get('KV')
// → 'Kana_Voicing'
```
## 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.
