Apify SDK Patterns

Overview

Production patterns for both the apify SDK (building Actors) and apify-client (calling Actors remotely). Covers Crawlee crawler selection, data storage, proxy configuration, and typed client wrappers.

Prerequisites

• apify-client and/or apify + crawlee installed
• APIFY_TOKEN configured
• TypeScript recommended

Pattern 1: Typed Client Singleton

// src/apify/client.ts
import { ApifyClient } from 'apify-client';

let instance: ApifyClient | null = null;
