IMPORTANT

Make sure Ivy is disabled and allow synthetic default imports in the tsconfig.json:

"compilerOptions": {
   "allowSyntheticDefaultImports": true
},
"angularCompilerOptions": {
  "enableIvy": false
}

Make sure AOT is disabled and allow lodash CommonJs in the angular.json:

{ 
    "architect": {
        "build": {
          "builder": "@angular-devkit/build-angular:browser",
          "options": {
            "outputPath": "dist/workspace",
            "index": "src/index.html",
            "main": "src/main.ts",
            "polyfills": "src/polyfills.ts",
            "tsConfig": "tsconfig.app.json",
            
            "aot-info": "make sure it is false",
            "aot": false,

            "allowedCommonJsDependencies-info": "allow lodash common js dependencies",
            "allowedCommonJsDependencies": ["lodash"],

            "assets": [
              "src/favicon.ico",
              "src/assets"
            ],
            "styles": [
              "src/styles.scss"
            ],
            "scripts": []
          }
    }
}

Usage

import { CompileModule} from "p3x-angular-compile"

// the module settings
@NgModule({
    imports: [
        CorifeusWebMaterialModule, // Optional
        CompileModule, // Required
    ],
    declarations: [
        Page,
    ],
    providers: [
    ],
    bootstrap: [ Page ]
})
export class Module { };

Template

 <span 
 
 <!--- Not required -->
 *ngIf="isEnabled" 

 <!--- Required -->
 [p3x-compile]="template"

 <!--- Required -->
 [p3x-compile-ctx]="this"

 <!--- Not required, will just throw the component's exception if not provided -->
 [p3x-compile-error-handler]="handleCompileErrorHandler"

 <!--- Not required -->
 [p3x-compile-module]="dataModule"
 >     
</span>

Code

// A page example
export class Page {
    
    isEnabled: boolean = true;
    
    dataModule : any =  {
        //schemas: [CUSTOM_ELEMENTS_SCHEMA],
        //declarations: [],
        imports: [
            MatButtonModule
        ],
        exports: [       
        ]
    }

    template: string = "<button mat-button mat-raised-button (click)="context.alert()">Dynamic template</button>";

    handleCompileErrorHandler(error: Error) {
        console.error(error)
    }

    alert() {
        alert('ok');
    }
}

Errors

Type x is part of the declarations of 2 modules

Basically, you need a shared component.

AOT + JIT

Since Angular 5.x.x +

We cannot use AOT + JIT at once.

Info

On the issue, you can see:

To reduce the payload, we do not ship the compiler in AOT.

So right now, it is not possible.

Although, there are some hacks, but you are on your own...

Size

If you want very small bundle, use gzip.

All my domains (patrikx3.com and corifeus.com) could have minor errors, since I am developing in my free time. However, it is usually stable.
