micsapp Customer.io SDK Patterns
Overview
Production-ready patterns for Customer.io SDK usage including type-safe clients, retry logic, event batching, and singleton management.
Prerequisites
- Customer.io SDK installed
- TypeScript project (recommended)
- Understanding of async/await patterns
Instructions
Step 1: Build a Type-Safe Client
Define TypeScript interfaces for user attributes and event names. Create a typed wrapper that enforces correct attribute types and event name enums.
Step 2: Add Retry with Exponential Backoff
Wrap operations with configurable retry logic that handles transient errors with exponential delay and skips retries on client errors.
Step 3: Implement Event Queue with Batching
Build an event queue that buffers track calls, auto-flushes on size threshold or time interval, and processes in parallel batches.
Step 4: Use Singleton with Lazy Initialization
Create a singleton factory that validates credentials and reuses a single TrackClient instance across the application.

Output
- Type-safe Customer.io client with TypeScript interfaces
- Resilient error handling with configurable retries
- Event batching for high-volume scenarios
- Singleton pattern for resource efficiency
Error Handling
| Error | Cause | Solution |
|---|---|---|
| Type mismatch | Invalid attribute type | Use TypeScript interfaces |
| Queue overflow | Too many events | Increase flush frequency |
| Retry exhausted | Persistent failure | Check network and credentials |

Examples
Basic usage: Apply customerio sdk patterns to a standard project setup with default configuration options.
Advanced scenario: Customize customerio sdk patterns for production environments with multiple constraints and team-specific requirements.
