Cohere Streaming Events & Connectors

Overview

Handle Cohere's streaming chat events (SSE), tool-call events, citation events, and register data connectors for RAG. Cohere does not use traditional webhooks — its event model is streaming-based.

Prerequisites

• cohere-ai SDK v7+
• Understanding of Server-Sent Events (SSE)
• For connectors: HTTPS endpoint accessible from internet

Instructions

Step 1: Chat Streaming Events

Cohere's chatStream returns a stream of typed events:

import { CohereClientV2 } from 'cohere-ai';

const cohere = new CohereClientV2();

async function handleStream(userMessage: string) {
  const stream = await cohere.chatStream({
    model: 'command-a-03-2025',
    messages: [{ role: 'user', content: userMessage }],
  });

  for await (const event of stream) {
    switch (event.type) {
      // Text content streaming
      case 'content-start':
        console.log('--- Generation started ---');
        break;

      case 'content-delta':
        const text = event.delta?.?.?. ?? ;
        process..(text);
        ;

       :
        .();
        ;

      
       :
        .(, event.?.?.);
        ;

      
       :
        .(, event.?.?.?.?.);
        ;

       :
        
        ;

       :
        .();
        ;

      
       :
        .(, event.);
        ;

       :
        .(, event.?.);
        .(, event.?.);
        ;
    }
  }
}
