Profanity filter callback

The Nexconn Chat SDK provides built-in content moderation to filter sensitive or inappropriate content.

How it works

Content moderation is applied automatically on the server when messages are sent. If a message contains blocked content, the server returns an error code, or the message is silently filtered, depending on your configuration.

Messages may be blocked when:

• Text content matches a built-in profanity word.
• Text content matches a custom profanity word set to block.
• A pre-messaging webhook rule blocks the message before delivery.

Client-side moderation callback

Register a MessageHandler to receive blocked message events:

TypeScript

import { NCEngine, MessageHandler, MessageBlockedEvent } from '@nexconn/chat';

NCEngine.addMessageHandler('moderation-handler', new MessageHandler({
  onMessageBlocked(event: MessageBlockedEvent): void {
    console.log('Message blocked:', event.info);
    // Show the user that their message was blocked
  },
}));

Configure moderation (server API)

Content moderation is configured through the Server API. See the Server API documentation for:

• Add profanity words
• Pre-messaging webhook event
