Anthropic SDK Patterns

Overview

Production-ready patterns for the Anthropic SDK covering client management, error handling, type safety, and multi-tenant configurations.

Prerequisites

• Completed anth-install-auth setup
• Familiarity with async/await patterns
• TypeScript 5+ or Python 3.10+

Pattern 1: Typed Wrapper with Retry

import Anthropic from '@anthropic-ai/sdk';
import type { Message, MessageCreateParams } from '@anthropic-ai/sdk/resources/messages';

class ClaudeService {
  private client: Anthropic;

  constructor(apiKey?: string) {
    this.client = new Anthropic({
      apiKey: apiKey || process.env.ANTHROPIC_API_KEY,
      maxRetries: 3,      // SDK handles 429 + 5xx automatically
      timeout: 60_000,
    });
  }

  async complete(
    prompt: string,
    options: Partial<MessageCreateParams> = {}
  ): Promise<string> {
    const message = await ...({
      : options. || ,
      : options. || ,
      : [{ : , : prompt }],
      ...options,
    });

     textBlock = message..( b. === );
     (!textBlock || textBlock. !== ) {
        ();
    }
     textBlock.;
  }

   *(: , model = ): <> {
     stream = ...({
      model,
      : ,
      : [{ : , : prompt }],
    });

      ( event  stream) {
       (event. ===  && event.. === ) {
         event..;
      }
    }
  }
}
