+# unicode-match-property-value-ecmascript [![unicode-match-property-value-ecmascript on npm](https://img.shields.io/npm/v/unicode-match-property-value-ecmascript)](https://www.npmjs.com/package/unicode-match-property-value-ecmascript)
+
+_unicode-match-property-value-ecmascript_ matches a given Unicode property value or [property value alias](https://github.com/mathiasbynens/unicode-property-value-aliases) to its canonical property value without applying [loose matching](https://github.com/mathiasbynens/unicode-loose-match), per the algorithm used for [RegExp Unicode property escapes in ECMAScript](https://github.com/tc39/proposal-regexp-unicode-property-escapes). Consider it a strict alternative to loose matching.
+
+## Installation
+
+To use _unicode-match-property-value-ecmascript_ programmatically, install it as a dependency via [npm](https://www.npmjs.com/):
+
+```bash
+$ npm install unicode-match-property-value-ecmascript
+```
+
+Then, `require` it:
+
+```js
+const matchPropertyValue = require('unicode-match-property-value-ecmascript');
+```
+
+## API
+
+This module exports a single function named `matchPropertyValue`.
+
+### `matchPropertyValue(property, value)`
+
+This function takes a string `property` that is a canonical/unaliased Unicode property name, and a string `value`. It attemps to  match `value` to a canonical Unicode property value for the given property. If there’s a match, it returns the canonical property value. Otherwise, it throws an exception.
+
+```js
+// Find the canonical property value:
+matchPropertyValue('Script_Extensions', 'Aghb')
+// → 'Caucasian_Albanian'
+
+matchPropertyValue('Script_Extensions', 'Caucasian_Albanian')
+// → 'Caucasian_Albanian'
+
+matchPropertyValue('script_extensions', 'Caucasian_Albanian') // Note: incorrect casing.
+// → throws
+
+matchPropertyValue('Script_Extensions', 'caucasian_albanian') // Note: incorrect casing.
+// → throws
+```
+
+## 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.
