Clay Local Dev Loop

Overview

Set up a fast, reproducible local development workflow for Clay.

Prerequisites

• Completed clay-install-auth setup
• Node.js 18+ with npm/pnpm
• Code editor with TypeScript support
• Git for version control

Instructions

Step 1: Create Project Structure

my-clay-project/
├── src/
│   ├── clay/
│   │   ├── client.ts       # Clay client wrapper
│   │   ├── config.ts       # Configuration management
│   │   └── utils.ts        # Helper functions
│   └── index.ts
├── tests/
│   └── clay.test.ts
├── .env.local              # Local secrets (git-ignored)
├── .env.example            # Template for team
└── package.json

Step 2: Configure Environment

set -euo pipefail
# Copy environment template
cp .env.example .env.local

# Install dependencies
npm install

# Start development server
npm run dev

Step 3: Setup Hot Reload

{
  "scripts": {
    "dev": "tsx watch src/index.ts",
    "test": "vitest",
    "test:watch": "vitest --watch"
  }
}

Step 4: Configure Testing

import { describe, it, expect, vi } from 'vitest';
import { ClayClient } from '../src/clay/client';

describe('Clay Client', () => {
  it('should initialize with API key', () => {
    const client = new ClayClient({ apiKey: 'test-key' });
    expect(client).toBeDefined();
  });
});

Output

• Working development environment with hot reload
• Configured test suite with mocking
• Environment variable management
• Fast iteration cycle for Clay development

Error Handling

Error	Cause	Solution
Module not found	Missing dependency	Run npm install
Port in use	Another process	Kill process or change port
Env not loaded	Missing .env.local	Copy from .env.example
Test timeout	Slow network	Increase test timeout

Examples

Mock Clay Responses

vi.mock('@clay/sdk', () => ({
  ClayClient: vi.fn().mockImplementation(() => ({
    // Mock methods here
  })),
}));

Debug Mode

set -euo pipefail
# Enable verbose logging
DEBUG=CLAY=* npm run dev
