Embed App Builder Web SDK in an Angular Web App

The following guide describes the process of embedding the App Builder Web SDK in an Angular web app.

BUILDING

STEP 1

You need to download and extract the app builder source code, you can read more here.

Run the app-builder-cli in your project folder using the following command:

npm i && npm run start

STEP 2

Navigate using the arrow keys and select the Build option using the enter key

STEP 3

Select the Web SDK platform, after which the CLI will start the build process. This will take a few minutes.

STEP 4

Once the build is complete open a terminal window in your Angular project directory.

STEP 5

The app-builder-cli compiles your App Builder project into a node module inside the <Agora App Builder>/Builds/web-sdk folder. Simply install this module using the following command.

npm install <path-to-app-builder-project-folder>/Builds/web-sdk

STEP 6

Navigate to <Agora App Builder>/Builds/web-sdk and copy the wasm folder , png and ttf files into your project's public assets folder.

USAGE

STEP 1

The module is installed with same name as your App Builder project. Import it just like any other node module into your desired angular component file.

import { Component } from "@angular/core";
import AgoraAppBuilder from "@appbuilder/web";

// To prevent removal of AgoraAppBuilder via dead code elimination.
console.log(AgoraAppBuilder);

STEP 2

After importing the module your App Builder project can be rendered using the <app-builder /> custom html element.

Make sure to provide necessary styling including a width and height on the parent element of the custom html element for proper scaling.

...
@Component({
  selector: 'app-root',
  template: ` <div id="app-builder-container">
    <app-builder></app-builder>
  </div> `,
  styles: [`
    #app-builder-container{
      width: 100vw;
      height: 100vh;
    }
  `],
})
...

STEP 3

You also need to add CUSTOM_ELEMENTS_SCHEMA in your module file for your component to enable support for custom html elements.

import { NgModule, CUSTOM_ELEMENTS_SCHEMA } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';

...

@NgModule({
  declarations: [AppComponent],
  imports: [BrowserModule],
  providers: [],
  bootstrap: [AppComponent],
  schemas: [CUSTOM_ELEMENTS_SCHEMA],
})

...

STEP 4

Start the development server inside your Angular project directory with the following command

ng serve

STEP 5

You should now see your App Builder project being displayed in your desired Angular component.

CUSTOMIZATIONS

STEP 1

You can use Customization APIs to customize your embedded App Builder project.

Read this guide for more information.

STEP 2

To create a Customization you need to access the createCustomization method on the imported AgoraAppBuilder object, which takes the UserCustomizationConfig as a parameter and returns a customization object.

import AgoraAppBuilder from "@appbuilder/web";

const customization = AgoraAppBuilder.createCustomization({
  /*
  My Customization Config. See https://appbuilder-docs.agora.io/customization-api/quickstart to get started with customizing!
*/
});

STEP 3

Pass the returned customization object to the customize method available under the same AgoraAppBuilder object to apply the config to your embedded App Builder project.

import AgoraAppBuilder from "@appbuilder/web";

const customization = AgoraAppBuilder.createCustomization({
  /*
  My Customization Config. See https://appbuilder-docs.agora.io/customization-api/quickstart to get started with customizing!
*/
});
AgoraAppBuilder.customize(customization);

STEP 4

You should now be able to see your customizations in action!
