Quick Start

Basic AI AssistView

import { AIAssistView, PromptRequestEventArgs } from '@syncfusion/ej2-interactive-chat';
import { enableRipple } from '@syncfusion/ej2-base';

enableRipple(true);

// Initialize AI AssistView
const aiAssistView: AIAssistView = new AIAssistView({
    promptSuggestions: [
        'How do I get started?',
        'What are the key features?'
    ],
    promptRequest: (args: PromptRequestEventArgs) => {
        // Handle prompt request - integrate with AI service here
        setTimeout(() => {
            const response = 'This is the AI response to: ' + args.prompt;
            aiAssistView.addPromptResponse(response);
        }, 1000);
    }
});

// Render to DOM
aiAssistView.appendTo('#aiAssistView');

Common Patterns

Pattern 1: OpenAI Integration

const aiAssistView: AIAssistView = new AIAssistView({
    promptSuggestions: ['Explain AI', 'Code example', 'Best practices'],
    promptRequest: async (args: PromptRequestEventArgs) => {
        try {
            const response = await fetch('https://api.openai.com/v1/chat/completions', {
                method: 'POST',
                headers: {
                    'Content-Type': 'application/json',
                    'Authorization': `Bearer ${OPENAI_API_KEY}`
                },
                body: JSON.stringify({
                    model: 'gpt-4',
                    messages: [{ role: 'user', content: args.prompt }]
                })
            });
            
            const data = await response.json();
            const aiResponse = data.choices[0].message.content;
            aiAssistView.addPromptResponse(aiResponse);
        } catch (error) {
            aiAssistView.addPromptResponse('Error: ' + error.message);
        }
    }
});

Pattern 2: Markdown Responses with Streaming

const aiAssistView: AIAssistView = new AIAssistView({
    enableStreaming: true,
    promptRequest: (args: PromptRequestEventArgs) => {
        // Simulate streaming response
        const markdownResponse = `# Response\n\nThis is **bold** and *italic* text.\n\n- Item 1\n- Item 2\n\`\`\`javascript\nconst x = 10;\n\`\`\``;
        
        let index = 0;
        const interval = setInterval(() => {
            if (index < markdownResponse.length) {
                const chunk = markdownResponse.slice(0, index + 5);
                aiAssistView.addPromptResponse(chunk, false);
                index += 5;
            } else {
                clearInterval(interval);
                aiAssistView.addPromptResponse(markdownResponse, true);
            }
        }, 50);
    }
});

Pattern 3: Custom Toolbar with Actions

const aiAssistView: AIAssistView = new AIAssistView({
    responseToolbarSettings: {
        items: [
            { type: 'Button', iconCss: 'e-icons e-copy', tooltip: 'Copy' },
            { type: 'Button', iconCss: 'e-icons e-assist-like', tooltip: 'Like' },
            { type: 'Button', iconCss: 'e-icons e-assist-dislike', tooltip: 'Dislike' }
        ],
        itemClicked: (args: ToolbarItemClickedEventArgs) => {
            if (args.item.iconCss.includes('copy')) {
                // Copy response to clipboard
                const responseText = aiAssistView.prompts[args.dataIndex].response;
                navigator.clipboard.writeText(responseText);
            } else if (args.item.iconCss.includes('like')) {
                console.log('User liked the response');
            }
        }
    }
});

Pattern 4: File Attachments

const aiAssistView: AIAssistView = new AIAssistView({
    enableAttachments: true,
    attachmentSettings: {
        allowedFileTypes: '.pdf,.docx,.txt,.jpg,.png',
        maxFileSize: 5242880, // 5MB
        maximumCount: 3,
        saveUrl: 'https://your-api.com/upload',
        removeUrl: 'https://your-api.com/remove'
    },
    promptRequest: (args: PromptRequestEventArgs) => {
        console.log('Attached files:', args.attachedFiles);
        // Process prompt with attached files
        aiAssistView.addPromptResponse('Received your prompt with attachments');
    }
});
