Is it possible to leverage Reflect.getMetadata() in Angular 2 version 2.0.0-rc1?

Is there a way to effectively utilize Reflect.getMetadata() in Angular version 2.0.0-rc1?

I noticed the definition of the Reflect namespace in typings ambient/es6-shim. Should I consider installing any additional packages for this functionality?

Answer №1

This is how I'm utilizing it:

Let result = window['Reflect'].getMetadata('annotations', target);

Answer №2

There are actually two important components to consider:

  • The compilation aspect. Typings are required for this part, which are now included in the core-js typings.

  • The execution aspect. To fully execute the code, you must ensure that Reflect.js is added to your main HTML page.

    <script src="node_modules/zone.js/dist/zone.js"></script>
    <script src="node_modules/reflect-metadata/Reflect.js"></script> <----
    <script src="node_modules/systemjs/dist/system.src.js"></script>
    

By following these steps, you will be able to utilize Reflect.getMetadata() within your code.
