Flyde Nodes Library
This is the documentation for the Flyde Nodes Library. It contains all the parts that are available in the @flyde/stdlib (which is copied to @flyde/runtime for convenience).
For simplicity, all parts of Flyde's standard library reside in the same package, and is organized into namespaces.
