reedx/src/propsFrom.js

Like redux but with less code

import reduce from './utils/reduce'
import isFunc from './utils/isFunc'

const { assign, keys, values } = Object

const mountObject = (model, selectors) =>
  reduce(keys(selectors), (obj, key, idx) => {
    const selector = values(selectors)[idx]

    return assign(obj, {
      [key]: isFunc(selector) ? selector(model) : mountObject(model, selector)
    })
  }, {})

const propsFrom = (...models) => (globalState) =>
  reduce(keys(models), (obj, key, idx) =>
    assign(obj, mountObject(globalState, values(models)[idx].selectors)), {})

export default propsFrom
