# 🆖 Angular Dynamic Compile - Convert strings to Angular components v2024.10.104



**Bugs are evident™ - MATRIX️**
    



### NodeJS LTS is supported

### Built on NodeJs version

```txt
v22.3.0
```




# Built on Angular

```text
18.0.5
```



# Description

                        
[//]: #@corifeus-header:end


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

## Check out how it works and code

https://angular-compile.corifeus.com  

https://github.com/patrikx3/angular-compile/blob/master/src/app/app.component.ts

## IMPORTANT


Make sure AOT is disabled in the `angular.json`:
```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

```bash
ng build --aot=false --build-optimizer=false
```


## Usage


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

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

#### Template    
```html
 <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
```typescript
// 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');
    }
}
```

<!--

#### Actual used dynamic compiler
I use a dynamic Markdown page with ```p3x-angular-compile```:
[Module](https://github.com/patrikx3/corifeus-app-web-pages/blob/master/src/angular/module.ts) , [Example page](https://github.com/patrikx3/corifeus-app-web-pages/blob/master/src/angular/modules/cory-page.ts)


#### Service
[Please refer to use an a service](https://github.com/patrikx3/angular-compile/blob/master/test/angular-webpack/angular/page.ts)

```typescript
export interface CompileOptions {   
    // cached by template
    template: string;
    container: ViewContainerRef;
    context?: any,
    
    // you can customize here any you want to
    // CommonModule, BrowserModule are auto added 
    // (like *ngIf and angular default directives)
    // though CompileModule.forRoot is usually enough
    // so you do not need to use it
    module?: NgModule;
    
    onCompiled?: Function,
    onError?: Function;

}
```

-->

### Options
[Reference for the Angular module settings which are available.](
https://github.com/angular/angular/blob/master/packages/core/src/metadata/ng_module.ts)

<!--
The templates are cached.
-->

<!--

### Deployed example
[Corifeus Pages (JIT + AOT at once)](https://corifeus.com)

#### For now, until there is no options in Angular to use JIT, I just use AOT, so I don't use this component  

[Corifeus Pages (AOT)](https://corifeus.com)

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:
```text
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...  
https://github.com/angular/angular/issues/20156#issuecomment-468686933

<!---
### Angular 4.x.x

It is not working out of the box (the default is either JIT or AOT, not both), but the apps become 10 folds faster. The ``@ngtools/webpack`` is AOT and the ```awesome-typescript-loader``` is JIT only. 
  
The solution can be architect with the ```@angular/compiler``` and the ```awesome-typescript-loader``` together. A miracle!

Example here (since I am using Angular 5 not, it is not AOT + JIT anymore, but if you are on Angular 4, you can do it):

### Size
If you want very small bundle, use ```gzip```.
