inferno-vnode-flags
Inferno VNode Flags is a small utility library for Inferno.
Usage of inferno-vnode-flags
should be limited to assigning VNodeFlags
and ChildFlags
when using creating vNodes.
Install

ChildFlags
ChildFlags.UnknownChildren
needs NormalizationChildFlags.HasInvalidChildren
is invalid (null, undefined, false, true)ChildFlags.HasVNodeChildren
(JSX $HasVNodeChildren) is single vNode (Element/Component)ChildFlags.HasNonKeyedChildren
(JSX $HasNonKeyedChildren) is Array of vNodes non keyed (no nesting, no holes)ChildFlags.HasKeyedChildren
(JSX $HasKeyedChildren) is Array of vNodes keyed (no nesting, no holes)ChildFlags.HasTextChildren
(JSX $HasTextChildren) vNode contains only text
ChildFlags Masks
ChildFlags.MultipleChildren
Is Array
You can easily combine multiple flags, by using bitwise operators. A common use case is an element that has keyed children:
