Getting Started - Angular

Supported Angular Versions

The PhotoEditorSDK will work in any Angular version with Typescript 3.x or higher. Angular version 6 and below use Typescript 2.x which is incompatible with the typings for the PhotoEditorSDK and will cause Typescript related compiler errors.

The only option to run v5 of the PhotoEditorSDK in the older versions of Angular would be to disable the library type checks in the compilerOptions of the tsconfig.json.

{
  "compilerOptions": {
    "skipLibCheck": true
  }
}

Let’s get started!

We will be using angular cli for simplicity.

Create a project
  • Start a new project by following the angular cli prompts

ng new my-app
cd my-app
ng serve

  • Then open http://localhost:4200/ to see your app.
Installing peer dependencies

PhotoEditor SDK needs following peer dependencies:

  1. React >= 16.8.6
  2. React DOM >= 16.8.6
  3. Styled Components >= 4.4
  • Run npm install --save react react-dom styled-components to include them in the project.
  • Run npm install --save-dev @types/react @types/react-dom to include the types in the project.
  • Add "allowSyntheticDefaultImports": true to the compilerOptions in tsconfig.json in order to compile React.
Installing PhotoEditor SDK
  • Run npm install --save photoeditorsdk.
  • Copy the contents from node_modules/photoeditorsdk/assets to src/assets/photoeditorsdk.
Creating an Editor component

Use the angular cli to generate the scaffold for your editor component.

ng generate component photo-editor
photo-editor.component.html
<div #psdkContainer style="width: 100vw; height: 100vh;"></div>
photo-editor.component.ts
import {
  Component,
  AfterViewInit,
  ViewChild,
  Input,
  ElementRef,
} from "@angular/core";
import { PhotoEditorSDKUI, EditorApi } from "photoeditorsdk/no-polyfills";

const license = "";

@Component({
  selector: "app-photo-editor",
  templateUrl: "./photo-editor.component.html",
})
export class PhotoEditorComponent implements AfterViewInit {
  @Input()
  public src: string;

  @ViewChild("psdkContainer")
  private container: ElementRef;

  public editor: EditorApi;

  ngAfterViewInit() {
    this.initEditor();
  }

  async initEditor() {
    try {
      if (this.editor) {
        this.editor.dispose();
      }

      this.editor = await PhotoEditorSDKUI.init({
        license,
        container: this.container.nativeElement,
        image: this.src,
        assetBaseUrl: "/assets/photoeditorsdk",
      });
    } catch (error) {
      console.log(error);
    }
  }
}
Add the component to the app
app.component.html
<app-photo-editor
  src="https://static.photoeditorsdk.com/libraries/unsplash/raw/PZAxzN5DPkc.jpg"
></app-photo-editor>
Add the necessary polyfills

The PhotoEditorSDK will require some polyfills to work in IE11.

The easiest option would be to let core-js@3.x polyfill all stable ES and web standards:

polyfills.ts
// Polyfill only stable `core-js` features - ES and web standards:
import "core-js/stable";

It is also possible to only polyfill the necessary features by installing react-app-polyfill:

polyfills.ts
// Polyfills Promise, fetch, Object.assign, Symbol, Set, Map
import "react-app-polyfill/ie11";
// Loads core-js/stable, regenerator-runtime
import "react-app-polyfill/stable";
import "core-js/features/array/find";
import "core-js/features/array/map";

Add the following snippet to the polyfills.ts if you encounter this error message process is not defined:

(window as any).process = {
  env: { DEBUG: undefined },
};

CORS

If you are loading images from external sources (e.g. from an AWS bucket), you need to first configure Cross-Origin Resource Sharing for both the server and the image.

Otherwise, you will see errors such as
Failed to execute 'texImage2D' on 'WebGLRenderingContext': The cross-origin image at [...] may not be loaded.
or
Unable to get image data from canvas because the canvas has been tainted.

Please follow the instructions on how to properly configure CORS here.

Ready to go!

There you have it. PhotoEditor SDK for the Web is ready to use. Refer to the configuration documentaion for more configuration options.
