What is the difference between pre- and post-collector transformers?

Pre-collector transformers run immediately after a Source captures data but before the Collector processes it. Post-collector transformers run after Collector enrichment but before the data is delivered to a specific Destination.

What is the core architecture of walkerOS?

walkerOS follows a Source → Collector → Destination pattern, which ensures a strict separation of concerns where each component has a single, replaceable job within the pipeline.

How do components communicate in a walkerOS flow?

All components communicate via a universal push interface. The elb() function is a common alias for collector.push, used to wire different components together seamlessly.

How do I initialize a walkerOS flow?

You can use the startFlow helper from the @walkeros/collector package, which allows you to programmatically define your sources, transformers, and destinations in either TypeScript or a flow.json configuration.

Guides developers through the Source-Collector-Destination architecture of walkerOS for building modular event processing pipelines.

This skill provides a comprehensive understanding of the walkerOS event processing lifecycle, focusing on the core principle of separation of concerns. It explains the architectural flow from data capture (Sources) through centralized processing (Collector) to final delivery (Destinations), including the implementation of pre- and post-collector transformer chains. It is an essential resource for developers designing composable tracking infrastructures, wiring components via the universal push interface, or configuring complex data pipelines using the startFlow helper.
