Integration as webcomponent

Using revo-grid web component collection within an Angular CLI project is a two-step process. We need to:

1. Include the CUSTOM_ELEMENTS_SCHEMA in the modules that use the components.
2. Call defineCustomElements() from main.ts (or some other appropriate place).

Including the Custom Elements Schema

Including the CUSTOM_ELEMENTS_SCHEMA in the module allows the use of the web components in the HTML markup without the compiler producing errors. This code should be added into the AppModule and in every other modules that use your custom elements. Here is an example of adding it to AppModule:

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

import { AppComponent } from './app.component';

@NgModule({
  declarations: [AppComponent],
  imports: [BrowserModule, FormsModule],
  bootstrap: [AppComponent],
  schemas: [CUSTOM_ELEMENTS_SCHEMA],
})
export class AppModule {}

The CUSTOM_ELEMENTS_SCHEMA needs to be included in any module that uses custom elements.

Calling defineCustomElements

A component collection built with Stencil includes a main function that is used to load the components in the collection. That function is called defineCustomElements() and it needs to be called once during the bootstrapping of your application. One convenient place to do this is in main.ts as such:

import { enableProdMode } from '@angular/core';
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';

import { AppModule } from './app/app.module';
import { environment } from './environments/environment';

// Note: loader import location set using "esmLoaderPath" within the output target config
import {defineCustomElements} from '@revolist/revogrid/loader';

if (environment.production) {
  enableProdMode();
}

platformBrowserDynamic().bootstrapModule(AppModule)
  .catch(err => console.log(err));
defineCustomElements();

Edge and IE11 polyfills

If you want your custom elements to be able to work on older browsers, you should add the applyPolyfills() that surround the defineCustomElements() function.

import { applyPolyfills, defineCustomElements } from '@revolist/revogrid/loader';
...
applyPolyfills().then(() => {
  defineCustomElements()
})

Accessing components using ViewChild and ViewChildren

Once included, components could be referenced in your code using ViewChild and ViewChildren as in the following example:

import {Component, ElementRef, ViewChild} from '@angular/core';

import '@revolist/revogrid';

@Component({
    selector: 'app-home',
    template: `<revo-grid/>`,
})
export class HomeComponent {
}
