Reflection
Lightweight ES Module implementation of reflect-metadata to work with TypeScript's experimental decorator support.
Why?
The main reason for this library is to provide a much smaller implementation that can be included as a module.
- ES module
reflection
can be loaded with <script type="module" src="..."></script>
- Size (uncompressed)
