## Overview
Production-ready patterns for Retell AI SDK usage in TypeScript and Python.
## Prerequisites
- Completed `retellai-install-auth` setup
- Familiarity with async/await patterns
- Understanding of error handling best practices
## Instructions
### Step 1: Implement Singleton Pattern (Recommended)
```typescript
// src/retellai/client.ts
import { RetellAIClient } from '@retellai/sdk';
let instance: RetellAIClient | null = null;
export function getRetell AIClient(): RetellAIClient {
if (!instance) {
instance = new RetellAIClient({
apiKey: process.env.RETELLAI_API_KEY!,
// Additional options
});
}
return instance;
}
```
### Step 2: Add Error Handling Wrapper
```typescript
import { Retell AIError } from '@retellai/sdk';
async function safeRetell AICall<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 Retell AIError) {
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
