# inferno-vnode-flags

Inferno VNode Flags is a small utility library for [Inferno](https://github.com/infernojs/inferno).

Usage of `inferno-vnode-flags` should be limited to assigning `VNodeFlags` and `ChildFlags` when using creating vNodes.

## Install

```
npm install --save inferno-vnode-flags
```

## Contents

**VNodeFlags:**

- `VNodeFlags.HtmlElement`
- `VNodeFlags.ComponentUnknown`
- `VNodeFlags.ComponentClass`
- `VNodeFlags.ComponentFunction`
- `VNodeFlags.Text`
- `VNodeFlags.SvgElement`
- `VNodeFlags.InputElement`
- `VNodeFlags.TextareaElement`
- `VNodeFlags.SelectElement`
- `VNodeFlags.Portal`
- `VNodeFlags.ReCreate` (JSX **$ReCreate**) always re-creates the vNode
- `VNodeFlags.ContentEditable`
- `VNodeFlags.Fragment`
- `VNodeFlags.InUse`
- `VnodeFlags.ForwardRef`
- `VNodeFlags.Normalized`

**VNodeFlags Masks:**

- `VNodeFlags.ForwardRefComponent` Functional component wrapped in forward ref
- `VNodeFlags.FormElement` - Is form element
- `VNodeFlags.Element` - Is vNode element
- `VNodeFlags.Component` - Is vNode Component
- `VNodeFlags.DOMRef` - Bit set when vNode holds DOM reference
- `VNodeFlags.InUseOrNormalized` - VNode is used somewhere else or came from normalization process
- `VNodeFlags.ClearInUseNormalized` - Opposite mask of InUse or Normalized

**ChildFlags**

- `ChildFlags.UnknownChildren` needs Normalization
- `ChildFlags.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:
