@stencil/angular-output-target
Stencil can generate Angular component wrappers for your web components. This allows your Stencil components to be used within an Angular application. The benefits of using Stencil's component wrappers over the standard web components include:
- Angular component wrappers will be detached from change detection, preventing unnecessary repaints of your web component.
- Web component events will be converted to RxJS observables to align with Angular's @Output() and will not emit across component boundaries.
- Optionally, form control web components can be used as control value accessors with Angular's reactive forms or [ngModel].

Installation
npm install @stencil/angular-output-target
Usage
In your stencil.config.ts
add the following configuration to the outputTargets
section:
import { Config } from '@stencil/core';
import { angularOutputTarget } from '@stencil/angular-output-target';
export const config: Config = {
namespace: 'demo',
outputTargets: [
angularOutputTarget({
componentCorePackage: 'component-library',
outputType: 'component',
directivesProxyFile: '../component-library-angular/src/directives/proxies.ts',
directivesArrayFile: '../component-library-angular/src/directives/index.ts',
}),
{
type: 'dist',
esmLoaderPath: '../loader',
},
],
};
Config Options
Property | Description |
---|
componentCorePackage | The NPM package name of your Stencil component library. This package is used as a dependency for your Angular wrappers. |
directivesProxyFile | The output file of all the component wrappers generated by the output target. This file path should point to a location within your Angular library/project. |
directivesArrayFile | The output file of a constant of all the generated component wrapper classes. Used for easily declaring and exporting the generated components from an NgModule . This file path should point to a location within your Angular library/project. |
valueAccessorConfigs | The configuration object for how individual web components behave with Angular control value accessors. |
excludeComponents | An array of tag names to exclude from generating component wrappers for. This is helpful when have a custom framework implementation of a specific component or need to extend the base component wrapper behavior. |
outputType | Specifies the type of output to be generated. It can take one of the following values: 1. component : Generates all the component wrappers to be declared on an Angular module. This option is required for Stencil projects using the dist hydrated output. 2. scam : Generates a separate Angular module for each component. 3. standalone : Generates standalone component wrappers. Both scam and standalone options are compatible with the dist-custom-elements output. Developers must set a customElementsDir in the output target config when using either 'scam' or 'standalone'. Note: Please choose the appropriate outputType based on your project's requirements and the desired output structure. |
customElementsDir | This is the directory where the custom elements are imported from when using the Custom Elements Bundle. Required to be set for outputType: "scam" or outputType: "standalone" . |
