Usage

To use this component in your Angular application follow the steps below:

1️⃣ Import Angular module FormioEditorModule as below:

import { FormioEditorModule } from '@davebaol/angular-formio-editor'; 

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    ....,
    FormioEditorModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

2️⃣ Setup your component models as below:

import { Component } from '@angular/core';
import { FormioEditorOptions } from '@davebaol/angular-formio-editor';

@Component({
  selector: 'app-root',
  template: `
    <div class="content" role="main">
      <div class="col-10 m-4">
        <formio-editor [form]="form" [options]="options"></formio-editor>
      </div>
    </div>
  `,
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  form: any;
  options: FormioEditorOptions;

  constructor() {
    this.form = {
      display: 'form',
      components: []
    };
    this.options = {
      builder: {
        hideDisplaySelect: true,
        output: {
          change: (event) => console.log('Demo: builder change event:', event),
        }
      },
      json: {
        changePanelLocations: ['top', 'bottom'],
        input: {
          options: {
            modes: ['code', 'tree', 'view'], // set allowed modes
            mode: 'view' // set default mode
          }
        }
      },
      renderer: {
        input: {
          options: {
            src: 'http://localhost:8765/api/v1/documents',
            renderOptions: { breadcrumbSettings: { clickable: true } }
          }
        }
      }
    };
  }
}

3️⃣ To properly style this component, import the .css files below into your main style.css file

@import "./styles/bootstrap/css/bootstrap.min.css";
@import '~font-awesome/css/font-awesome.min.css';
@import "~jsoneditor/dist/jsoneditor.min.css";
@import "~@davebaol/angular-formio-editor/styles.css";

Note that this library only needs the .css from bootstrap, not the .js, since ngx-bootstrap is used internally. So you don't have necessarily to add bootstrap and its peer dependency jQuery.

4️⃣ Troubleshooting

• If during ng build execution you encounter this error

  Generating ES5 bundles for differential loading...
  An unhandled exception occurred: Call retries were exceeded
  

  make sure you're using node 12+. If this does not work for you then try the other possible solutions mentioned here.
