Chat

The client.ai.chat.sendMessage() method enables conversational analytics — users describe what they want to see or understand, and the AI responds with insights, explanations, or generates and modifies dashboards.

Basic Usage

import { RevealSdkClient } from '@revealbi/api';

const client = RevealSdkClient.getInstance();

// Send a message and get the complete response
const response = await client.ai.chat.sendMessage({
  message: 'Show me sales trends for the last quarter',
  datasourceId: 'my-datasource',
});

console.log(response.explanation);
// "I've analyzed your sales data for Q4 2024..."

if (response.dashboard) {
  // Load the generated dashboard
  loadDashboard(response.dashboard);
}

Managing Conversation

The AI maintains server-side conversation history, enabling contextual follow-up questions. Clear the history to start fresh:

// Reset the conversation context
await client.ai.chat.resetContext();

console.log('Conversation history cleared');

Use this when:

• Starting a new topic
• Switching datasources
• The user explicitly requests to "start over"

Dashboard Context

Provide an existing dashboard for editing or analysis:

// Edit an existing dashboard
const response = await client.ai.chat.sendMessage({
  message: 'Add a date filter to this dashboard',
  datasourceId: 'my-datasource',
  dashboard: existingDashboardJson,  // Provide current dashboard JSON
});

if (response.dashboard) {
  // Load the modified dashboard
  loadDashboard(response.dashboard);
}

Using RVDashboard Objects:

// From RevealView
const currentDashboard = revealView.dashboard;

const response = await client.ai.chat.sendMessage({
  message: 'Explain what this dashboard shows',
  datasourceId: 'my-datasource',
  dashboard: currentDashboard,  // Accepts RVDashboard object
});

console.log(response.explanation);

Streaming

Add stream: true to any request to receive responses in real-time. See Streaming Responses for consumption patterns and examples.
