iota-hook

💫 Iota

Manage stateful logic with class methods like the good ol' times, but with reuable hooks.

Install

npm install iota-hook

Quickstart

Create a ususable instance of iota to grab a remote api data via debounce from incoming props

import createIota from 'iota-hook'
import debounce from 'lodash.debounce'
import searchQuery from './searchQuery'

const useLocationHook = createIota({
  init: (self) => {
    self.state = { searchResults: [] }
  },
  didUpdate: (self) => {
    const { props, prevProps } = self
    if (props.query !== prevProps.query) {
      self.search(props.query)
    }
  },
  didMount: (self) => {
    self.search = debounce(self.search, 1000)
  },
  search: async (self, arg) => {
    const results = await searchQuery(arg)
    self.setState({ searchResults: results })
  },
  render: (self) => {
    const { state } = self

    return {
      results: state.searchResults.map((location) => {
        const [city, country] = location.split(', ')
        return { city, country }
      }),
      amount: state.searchResults.length
    }
  }
})

Then you can reuse this in any component

import useLocationHook from './useLocationHook'

function App() {
  const [searchText, setSearchText] = React.useState('')

  const data = useLocationHook({ query: searchText })

  console.log({ data }) // data is data created from render method in iota hook

  return (
    <div>
      <input type="text" onChange={(e) => setSearchText(e.target.value)} />
    </div>
  );
}
