Polymorpheus

Polymorpheus is a tiny library for polymorphic templates in Angular.
It is 1 KB gzip, dependency free and allows you to make pretty cool things.

What does it do?

It abstracts over different ways of view customization in Angular with one simple structural directive:

<ng-container *polymorpheusOutlet="content as text; context: context">{{text}}</ng-container>

Content accepts:

primitives like number or string
functions that take context as argument and return a primitive
templates that get instantiated with given context
components that would get context injected through DI

Context is optional when you need your content to adapt to the situation

How to use it?

Typical use case would be a component that accepts visual customization and defines context by itself. Say a menu list where you can configure how each item should look like by passing a template. And context would be item itself and, for example, whether it is focused or not.

Please see extensive demo.
