🆖 Angular Dynamic Compile - Convert strings to Angular components

Built on Angular v13.0.1

WARNING 

Angular has changed, so it stricts many things for dynamic compilation. The only solution right now, is to simple copy the code into your code and it will work (like on https://angular-compile.corifeus.com/ ).

The code you just copy into your project is here:
https://github.com/patrikx3/angular-compile/tree/master/projects/angular-compile/src/lib

The package on the NPM is the pure TypeScript code. Not built using Angular.

Use case 

Dynamically compile standard strings to fully functional Angular components. Supports imports, exports, and standard context.

Install 

npm install --save p3x-angular-compile
# or
yarn add p3x-angular-compile

Check out how it works and code

IMPORTANT 

Make sure AOT is disabled 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",
            
            // make sure it is false
            "aot": false,

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

Minimum build requirement arguments 

ng build --aot=false --build-optimizer=false

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 

\n [p3x-compile-error-handler]=\"handleCompileErrorHandler\"\n\n \n [p3x-compile-module]=\"dataModule\"\n > \n")'>
 <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');
    }
}

Options 

Reference for the Angular module settings which are available.

Dev environment end test 

npm install -g yarn
git clone https://github.com/patrikx3/angular-compile.git
cd angular-compile
npm install
npm run start

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 

https://github.com/angular/angular/issues/20156#issuecomment-341767899

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.
