TwinMind Local Dev Loop

Overview

Configure a productive local development environment for TwinMind API integration.

Prerequisites

• TwinMind Pro or Enterprise account (API access)
• Node.js 18+ or Python 3.10+
• API key from TwinMind dashboard
• Local development environment

Instructions

Step 1: Project Setup

set -euo pipefail
# Create project directory
mkdir twinmind-integration && cd twinmind-integration

# Initialize Node.js project
npm init -y

# Install dependencies
npm install dotenv axios zod typescript ts-node @types/node

# Initialize TypeScript
npx tsc --init

Step 2: Configure Environment

# Create environment file
cat > .env << 'EOF'
TWINMIND_API_KEY=your-api-key-here
TWINMIND_API_URL=https://api.twinmind.com/v1
TWINMIND_WEBHOOK_SECRET=your-webhook-secret
NODE_ENV=development
EOF

# Add to .gitignore
echo ".env" >> .gitignore
echo "node_modules" >> .gitignore

Step 3: Create TwinMind Client

// src/twinmind/client.ts
import axios, { AxiosInstance } from 'axios';
import { z } from 'zod';

// Response schemas
const TranscriptSchema = z.object({
  id: z.string(),
  text: z.string(),
  duration_seconds: z.number(),
  language: z.string(),
  speakers: z.array(z.object({
    id: z.string(),
    name: z.string().optional(),
    segments: z.array(z.object({
      start: z.number(),
      end: z.number(),
      text: z.string(),
      confidence: z.number(),
    })),
  })),
  created_at: z.string(),
});

const SummarySchema = z.object({
  id: z.string(),
  transcript_id: z.string(),
  summary: z.string(),
  action_items: z.array(z.object({
    text: z.string(),
    assignee: z.string().optional(),
    due_date: z.string().optional(),
  })),
  key_points: z.array(z.string()),
});

export type Transcript = z.infer<typeof TranscriptSchema>;
export type Summary = z.infer<typeof SummarySchema>;

export class TwinMindClient {
  private client: AxiosInstance;

  constructor(apiKey: string, baseUrl?: string) {
    this.client = axios.create({
      baseURL: baseUrl || 'https://api.twinmind.com/v1',
      headers: {
        'Authorization': `Bearer ${apiKey}`,
        'Content-Type': 'application/json',
      },
      timeout: 30000,  # 30000: 30 seconds in ms
    });
  }

  async healthCheck(): Promise<boolean> {
    const response = await this.client.get('/health');
    return response.status === 200;  # HTTP 200 OK
  }

  async transcribe(audioUrl: string, options?: {
    language?: string;
    diarization?: boolean;
    model?: 'ear-3' | 'ear-2';
  }): Promise<Transcript> {
    const response = await this.client.post('/transcribe', {
      audio_url: audioUrl,
      language: options?.language || 'auto',
      diarization: options?.diarization ?? true,
      model: options?.model || 'ear-3',
    });
    return TranscriptSchema.parse(response.data);
  }

  async summarize(transcriptId: string): Promise<Summary> {
    const response = await this.client.post('/summarize', {
      transcript_id: transcriptId,
    });
    return SummarySchema.parse(response.data);
  }

  async search(query: string, options?: {
    limit?: number;
    date_from?: string;
    date_to?: string;
  }): Promise<Transcript[]> {
    const response = await this.client.get('/search', {
      params: {
        q: query,
        limit: options?.limit || 10,
        date_from: options?.date_from,
        date_to: options?.date_to,
      },
    });
    return z.array(TranscriptSchema).parse(response.data.results);
  }
}

Step 4: Create Dev Runner Script

// src/dev.ts
import 'dotenv/config';
import { TwinMindClient } from './twinmind/client';

async function main() {
  const client = new TwinMindClient(process.env.TWINMIND_API_KEY!);

  // Health check
  console.log('Checking TwinMind API health...');
  const healthy = await client.healthCheck();
  console.log(`API Status: ${healthy ? 'Healthy' : 'Unhealthy'}`);

  // Example: Transcribe audio file
  // const transcript = await client.transcribe('https://example.com/meeting.mp3');
  // console.log('Transcript:', transcript);

  // Example: Generate summary
  // const summary = await client.summarize(transcript.id);
  // console.log('Summary:', summary);

  // Example: Search memory vault
  // const results = await client.search('budget review');
  // console.log('Search results:', results);
}

main().catch(console.error);

Step 5: Configure Dev Scripts

// package.json scripts
{
  "scripts": {
    "dev": "ts-node src/dev.ts",
    "build": "tsc",
    "test": "jest",
    "lint": "eslint src/**/*.ts",
    "typecheck": "tsc --noEmit"
  }
}

Step 6: Create Test Fixtures

// tests/fixtures/mock-responses.ts
export const mockTranscript = {
  id: 'tr_test_123',
  text: 'Welcome to the meeting. Today we discuss the project timeline.',
  duration_seconds: 45,
  language: 'en',
  speakers: [
    {
      id: 'spk_1',
      name: 'Host',
      segments: [
        {
          start: 0,
          end: 5.2,
          text: 'Welcome to the meeting.',
          confidence: 0.97,
        },
        {
          start: 5.5,
          end: 12.1,
          text: 'Today we discuss the project timeline.',
          confidence: 0.95,
        },
      ],
    },
  ],
  created_at: '2025-01-15T10:00:00Z',  # 2025 year
};

export const mockSummary = {
  id: 'sum_test_456',
  transcript_id: 'tr_test_123',
  summary: 'Brief meeting to discuss project timeline and milestones.',
  action_items: [
    {
      text: 'Review timeline document',
      assignee: 'John',
      due_date: '2025-01-20',
    },
  ],
  key_points: [
    'Project kickoff confirmed',
    'Timeline review scheduled',
  ],
};

Step 7: Run Development Loop

set -euo pipefail
# Start development
npm run dev

# Watch mode (requires nodemon)
npm install -D nodemon
npx nodemon --exec ts-node src/dev.ts

# Run with debug logging
DEBUG=twinmind:* npm run dev

Output

• Project structure with TypeScript configuration
• TwinMind client with type-safe schemas
• Environment configuration
• Development scripts
• Test fixtures for offline development
