SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps developers understand how walkerOS destinations receive, transform, and deliver events to third‑party tools, while clarifying the role of the env pattern in safe integration.

Core Features & Use Cases

  • Destination Interface: methods init(context) (optional), push(event, context) (required), pushBatch(batch, context) (optional), config (required).
  • Env pattern: dependency injection via env for external APIs to enable testing without mocks.
  • Locality: applies to web and server destinations, with examples referenced in the repository.
  • Testing strategy guidance: how to test destinations using env mocks and examples in the codebase.
  • Configuration: understanding destination settings, mapping, consent, and policy.

Quick Start

  • Review the Destination Interface in packages/core/src/types/destination.ts.
  • Inspect how env is injected and mocked in tests (see testing with env).
  • Create a simple destination mock with a minimal config and simulate pushing an event using a mocked env.

Frequently Asked Questions about walkeros-understanding-destinations

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
What is the env pattern for dependency injection in walkerOS destinations?▼

Use the env pattern to inject dependencies into walkerOS destinations, allowing you to simulate external API calls and test event delivery logic safely without mocking frameworks.

How do I implement a custom destination interface for data transformation?▼

Implement the required push(event, context) method and config object, optionally adding init(context) and pushBatch(batch, context) methods to handle event reception, transformation, and delivery.

How do I test destinations using env mocks instead of standard mocking libraries?▼

Pass a mocked env object containing simulated external APIs into your destination tests to verify event transformation, consent handling, and delivery logic without actual network calls.

Do walkerOS destinations work across both web and server environments?▼

Yes, destinations apply to both web and server contexts, allowing you to standardize event transformation, configuration, and delivery logic across different execution environments.

What configuration settings are required for a walkerOS destination?▼

A destination requires a config object to manage settings, data mapping, consent rules, and delivery policies, ensuring events are correctly transformed and routed to third-party tools.
