Creating vvvv gamma Node Libraries

A node library is a project that provides multiple nodes to vvvv gamma as a distributable package. This skill covers the project-level concerns: directory structure, naming conventions, category organization, service registration, and node factories.

For writing individual node classes (ProcessNode, Update, pins, change detection), see vvvv-custom-nodes. For consuming services inside node constructors (IFrameClock, Game, logging), see vvvv-custom-nodes/services.md.

Creating your own library vs. contributing to one you don't own are different tasks. This SKILL.md and its design/publishing references cover creating and distributing a package. To change or submit a PR to an existing/upstream library (fork → branch → PR workflow, editable source packages, the .vl diff problem), see contributing.md.

Library Recognition Pattern

vvvv recognizes a directory as a library when the folder name, .vl file, and .nuspec all share the same name:
