Yarn Documentation

Every relation on a Craft site, from both ends

Installation

Requirements, installing, the permissions Yarn adds, the first run and uninstalling.

The map, one element’s relations, asset usage, globals, findings, Twig, the console and export.

What counts as a relation, performance limits and caching, reporting, and per-environment overrides.

The eight checks Yarn runs, what each one means and what to do about it.

Contributing your own relations, adjusting the graph and adding findings from another plugin.

An empty map, stale graphs, noisy findings, memory limits, a missing panel and why deletes aren’t blocked.

Common questions about what Yarn sees, what it changes and why it won’t stop a delete.
