Overview

Production-ready patterns for Clay SDK usage in TypeScript and Python.

Prerequisites

•Completed clay-install-auth setup
•Familiarity with async/await patterns
•Understanding of error handling best practices

Instructions

Step 1: Implement Singleton Pattern (Recommended)

typescript

// src/clay/client.ts
import { ClayClient } from '@clay/sdk';

let instance: ClayClient | null = null;

export function getClayClient(): ClayClient {
  if (!instance) {
    instance = new ClayClient({
      apiKey: process.env.CLAY_API_KEY!,
      // Additional options
    });
  }
  return instance;
}

Step 2: Add Error Handling Wrapper

typescript

import { ClayError } from '@clay/sdk';

async function safeClayCall<T>(
  operation: () => Promise<T>
): Promise<{ data: T | null; error: Error | null }> {
  try {
    const data = await operation();
    return { data, error: null };
  } catch (err) {
    if (err instanceof ClayError) {
      console.error({
        code: err.code,
        message: err.message,
      });
    }
    return { data: null, error: err as Error };
  }
}

Step 3: Implement Retry Logic

typescript

async function withRetry<T>(
  operation: () => Promise<T>,
  maxRetries = 3,
  backoffMs = 1000
): Promise<T> {
  for (let attempt = 1; attempt <= maxRetries; attempt++) {
    try {
      return await operation();
    } catch (err) {
      if (attempt === maxRetries) throw err;
      const delay = backoffMs * Math.pow(2, attempt - 1);
      await new Promise(r => setTimeout(r, delay));
    }
  }
  throw new Error('Unreachable');
}

Output

•Type-safe client singleton
•Robust error handling with structured logging
•Automatic retry with exponential backoff
•Runtime validation for API responses

Error Handling

Pattern	Use Case	Benefit
Safe wrapper	All API calls	Prevents uncaught exceptions
Retry logic	Transient failures	Improves reliability
Type guards	Response validation	Catches API changes
Logging	All operations	Debugging and monitoring

Examples

Factory Pattern (Multi-tenant)

typescript

const clients = new Map<string, ClayClient>();

export function getClientForTenant(tenantId: string): ClayClient {
  if (!clients.has(tenantId)) {
    const apiKey = getTenantApiKey(tenantId);
    clients.set(tenantId, new ClayClient({ apiKey }));
  }
  return clients.get(tenantId)!;
}

Python Context Manager

python

from contextlib import asynccontextmanager
from clay import ClayClient

@asynccontextmanager
async def get_clay_client():
    client = ClayClient()
    try:
        yield client
    finally:
        await client.close()

Zod Validation

typescript

import { z } from 'zod';

const clayResponseSchema = z.object({
  id: z.string(),
  status: z.enum(['active', 'inactive']),
  createdAt: z.string().datetime(),
});
