Opt-in architecture

In an effort to keep our bundle size small in the long run our SDK uses an architecture where integrators can decide to opt-out of certain costly (in terms of bundle size) features.

The decision to opt-in or opt-out happens at module import, you can choose between the StreamAutocompleteTextareaModule and the StreamTextareaModule:

import { NgModule } from "@angular/core";
import { BrowserModule } from "@angular/platform-browser";
import { TranslateModule } from "@ngx-translate/core";

import { AppComponent } from "./app.component";
import { CustomMessageComponent } from "./custom-message/custom-message.component";
import {
} from "stream-chat-angular";

declarations: [AppComponent, CustomMessageComponent],
imports: [
providers: [],
bootstrap: [AppComponent],
export class AppModule {}

The chosen module decides what kind of textarea should be used in the message composer, you can choose between the AutocompleteTextareaComponent with mentions or the TextareaComponent that doesn't support mentions, but has a smaller bundle size. Your final application bundle will only include either the TextareaComponent or the AutocompleteTextareaComponent.
