Enhance

Enhancers are async functions that have access to the system context. The enhancers are executed during reads and are only triggered on root elements of a read. An enhancer should result with an array of updates for the element subtree.

register(asyncFn)

Registers an enhancer.

Usage

import { enhance } from '@skele/classic'

enhance.register(async context => {
  await sleep(50)
  const timestamp = new Date().getTime()
  return [
    ['scene', el => el.update('metadata', m => m.set('timestamp', timestamp))],
    [
      ['scene', 'article'],
      el => el.update('metadata', m => m.set('type', 'article')),
    ],
  ]
})

const sleep = ms => new Promise(resolve => setTimeout(resolve, ms))
