+Reflection
+====
+
+Lightweight ES Module implementation of [reflect-metadata](https://github.com/rbuckton/reflect-metadata/) to work with TypeScript's [experimental decorator support](https://www.typescriptlang.org/docs/handbook/decorators.html).
+
+Why?
+----
+
+The main reason for this library is to provide a much smaller implementation that can be included as a module.
+
+- `reflect-metadata` is 52 K without compression while `reflection` is about 3 K
+- `reflection` can be loaded with ``
+
+Install
+----
+
+```sh
+npm install @abraham/reflection
+```
+
+Usage
+-----
+
+```ts
+import { Reflection as Reflect } from '@abraham/reflection';
+Reflect.defineMetadata(metadataKey, metadataValue, target);
+```
+
+If a globally available version you can use the following.
+
+```ts
+import '@abraham/reflection/dist/reflect';
+Reflect.defineMetadata(metadataKey, metadataValue, target);
+```
+
+
+API
+----
+
+Reflection does not cover the complete API surface of reflect-metadata. Currently the following are available.
+
+```ts
+Reflect.decorate(...);
+Reflect.defineMetadata(...);
+Reflect.getMetadata(...);
+Reflect.hasOwnMetadata(...);
+Reflect.metadata(...);
+```
