es7-reflect-metadata's Issues

when getting metadata of a class, does it have to be an instance of a class or can it be the type

Hi - as title.

I have created a class decorator that defines if the class (which is a react screen) should show up in the main menu, and at what order etc.

I have the menu doing the reflection, and do not want to create instances of the screens to pass in. passing types fails..

Additionally, (and probably warrants its own separate thread), I dont like the pattern of explicity passing types/objects to my renderer component, and want that component instead to be able to scan for all classes that implement that metadata, but it doesnt seem possible without grouping all the possible classes into one file wrapped in a module directive.

crypto not found

I'm getting two errors in my browser console (Chrome latest). See end of message for call stacks.
My webpack build succedes, but the browser won't finish loading the page due to the errors. My package.json specifies:
"es7-reflect-metadata": "^1.5.5",

What am i doing wrong

Thanks to help the community.
I succesfully applied meta data using Reflect.defineMetadata... but when i go declarative way i get errors. I think i did not understand the tutorial well please help

import  "./reflect-metadata";
export class Address {
    @Reflect.metadata("Obsolete","true") <-- this throws error
    method() {
    }
}

Package.json has reference to dist/index.js

package.json still has reference to dist/index.js and 1.2.0 version doesn't work properly if install via npm.

What does `es7` mean?

I have a question. I couldn't understand what the name, es7-reflect-metadata, means.

Draft of ES7 (should be called as ES2016) has been snapshotted already. ReflectMetadata never be included by ES7.

I think this package is just a fork of reflect-metadata package for supporting UMD and Webpack. Why did you name this es7-reflect-metadata?

Thank you.
