NGX Feature Toggle

The simplest solution for feature toggles in Javascript. Simple how it should be.

Why Feature toggle?

This is a common concept, but why use this directive instead solve it via server-side rendering?

The idea of this directive is make this process transparent and easier. So the main point is integrate this directive with other tooling process, such as:

• Server-side rendering;
• Progressive rendering;
• Any other that yoy like :)

You can integrate with WebSockets or handling this in a EventSourcing architecture. It's totally transparent for you and you can integrate easier in your application.
