Polymorpheus is a tiny library for polymorphic templates in Angular.


Polymorpheus is a lightweight library for polymorphic templates in Angular. It is highly versatile, with just 1 KB in size and no dependencies. It provides a simple structural directive that abstracts over different ways of view customization in Angular, making it easy to create dynamic and adaptable content.


  • Content customization: Polymorpheus allows customization of content using various options such as primitives (numbers or strings), functions that take context as an argument and return a primitive, templates that can be instantiated with given context, and components that receive context through Dependency Injection (DI).
  • Optional context: Context is optional when you need your content to adapt to different situations. This allows for flexible customization based on specific requirements.
  • Dynamic component content: If you use component content, you can inject context with the POLYMORPHEUS_CONTEXT token. This allows for accessing and manipulating the context object within the component.
  • Adding type to template context: Polymorpheus provides a directive to add type to the template context. This can be useful for enhancing type safety and clarity in your code.


To install Polymorpheus, follow these steps:

  1. Open your terminal and navigate to your project directory.
  2. Run the following command to install Polymorpheus from npm: npm install polymorpheus
  3. Once the installation is complete, you can import the library into your Angular project using the import statement: import { PolymorpheusModule } from 'polymorpheus';
  4. Add the PolymorpheusModule to the imports array in your NgModule decorator to make it available throughout your application.
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { PolymorpheusModule } from 'polymorpheus';

  imports: [
  // ...
export class AppModule { }

Now you can start using Polymorpheus in your Angular components.
