π Angular Dynamic Compile - Convert strings to Angular components
Built on Angular v21.2.9
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-compileCheck 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=falseUsage
CompileAttribute is now a standalone component. You can use it either directly in a standalone component or via the legacy CompileModule NgModule β both paths are fully supported.
Standalone (Angular 16+)
import { Component } from '@angular/core';
import { CompileAttribute } from 'p3x-angular-compile';
@Component({
selector: 'my-page',
standalone: true,
imports: [CompileAttribute],
template: `<span [p3x-compile]="template" [p3x-compile-ctx]="this"></span>`,
})
export class Page {
template = '<button (click)="context.alert()">Dynamic template</button>';
alert() { alert('ok'); }
}Legacy NgModule (unchanged)
import { CompileModule } from 'p3x-angular-compile';
@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');
}
}Options

Dev environment end test
npm install -g yarn
git clone https://github.com/patrikx3/angular-compile.git
cd angular-compile
npm install
npm run startErrors
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.

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...
