@dwalter/spider-hook

State management for React that just works.

spider-hook replaces redux, react-redux, redux-thunk, and reselect without all the bloat.

• spider-hook and its 2 dependencies are smaller than react-redux is alone.
• spider-hook exports only 8 members, and only half of those are frequently used.
• spider-hook is made to play nice with all your favorite tools including typescript, prettier, eslint/tslint, vscode, and webpack/rollup.
• spider-hook performs similarly to aggressively used reselect.

Under the hood, spider-hook uses @dwalter/spider-store to do the heavy lifting. This has one extra benefit: spider-hook automatically and safely handles state stores split up across multiple bundles. Your state will be unaffected by load order.

// state reducer function
function counterReducer(state = 0, action) {
  switch (action.type) {
    case 'increment': {
      return state + 1
    }
    default: {
      return state
    }
  }
}

// action creator
// (note the reducers prop on the action)
function increment() {
  return {
    type: 'increment',
    reducers: [counterReducer],
  }
}

// boilerplate in App component
function App() {
  return (
    <SpiderRoot>
      <Counter />
    </SpiderRoot>
  )
}

// component consuming state
function Counter() {
  const count = useSelector(counterReducer)
  const actions = useActions({ increment })

  return <div onClick={actions.increment}>{count}</div>
}
