Special Types

Children Var

Children Var is passed as @children to all components (available inside of a <define-component> block). It contains all the evaluated children of the component. You must pass a valid ChildrenVar object to the bind expression of <h-children>. Because most of the getters return ChildrenVar objects they can be chained.


// access children by slot.  
// ".noslot" will find children not tagged with a slot
// ".byslot" will access children tagged with the given slot name
<h-children bind="@children.noslot"></h-children>
<h-children bind="@children.noslot.tags"></h-children>
<h-children bind="@children.byslot['head']"></h-children>

// only children which are 'tags' (filters out text/comments)
<h-children bind="@children.tags"></h-children>

// children by index, or first child
<h-children bind="@children.byindex[0]"></h-children>
<h-children bind="@children.first"></h-children>

// children by tag name
// for libraries use bycomp['[lib-name]:[comp-name]']
<h-children bind="@children.bytag['a']"></h-children>
<h-children bind="@children.bycomp['hibiki/bulma:option']"></h-children>

Property Description
size number of children
noslot returns children not tagged with a slot name (includes text/whitespace/comment nodes)
tags filters children to only include children which are tags (excludes text and whitespace)
first returns first child
byindex returns an array of childrenvar objects, each with one child (by index)
bytag returns an object mapping tag names to childrenvars
bycomp returns an object mapping ‘[lib-name]:[comp-name]’ to children vars (useful for libraries to find their own components
node returns a NodeVar object of the first child
nodes returns an array of NodeVar objects
filter advanced. takes a lambda, calls it for each child (@node=NodeVar) and returns a new childrenvar object of the matching nodes
all all the children (noop), deprecated (for historical purposes)

Hibiki Blob

Hibiki Blob can represent images, videos, text, etc. They can be displayed by the appropriate tag (img, video, etc.) or downloaded by the user. They are stored as base64 dataurl values.

Property Description
mimetype the mimetype of the blob, e.g. ‘text/csv’, ‘image/jpeg’
bloblen size of blob (bytes)
name name of blob - not all blobs have names. usually a name comes from a file upload input and will contain the uploaded file name
base64 base64 string representation of the blob
text (v0.3.5) if the blob has mimetype of ‘text/*’ will return the text content of the blob
