AutocompleteTextareaComponent

The AutocompleteTextarea component is used by the MessageInput component to display the input HTML element where users can type their message.

Message send can be triggered with the Enter key, new line can be added with the Shift+Enter combination.

The AutocompleteTextarea extends the functionalities of the Textarea component with autocomplete features:

• users can mention other users in a message (transliteration is used to support languages with non-Latin characters)
• users can send commands (for example /giphy)

Basic usage

You can use the AutocompleteTextarea component if you want to create your own message input component to override the default one:

@Component({
  selector: "app-custom-message-input",
  template: `
    <stream-autocomplete-textarea
      [(value)]="textareaValue"
      (send)="messageSent()"
      (userMentions)="mentionedUsers = $event"
    ></stream-autocomplete-textarea>
    <!-- Other parts of the custom message input component -->
  `,
})
export class CustomMessageInputComponent {
  textareaValue = "";
  mentionedUsers = [];

  messageSent() {
    // Send your message
  }
}
