Implement an element factory

[schneiderfelipe]

The idea is to go beyond simple element generators but create simplified and efficient component/widget generators.

EDIT: Similar to how hyperscript-helpers do it. hyperaxe and elementx are also inspirations.

This can be done without any overhead using macros.

This could be an extreme case of composability. See material-hyperscript for a generalized use case.

Specifically, factories can be generalized to be able to:

• Return functions that construct any (partial) tree with already (with some children and attributes), which is related to the usefulness of #11
• Since those functions return repeated structures, they can be seen as templates, so #5 is very relatable

This can simplify some use cases, see the following widgets as examples of what could be done:

• sortable
• hyperlightbox
• hyperloadmore
• hypercrop
• hypertabs
• hyperscroll
