React hooks combine

Hooks powered, recompose like utility belt for ladies and gentlemen.

---

React Hooks Combine (RHC) is a simple utility belt to help you split up logic for your components between container (smart) part and dummy component (view) part. It helps you to create only one HOC effortlessly with custom hook which combines all listed HOOKS (all in one).

It has API Design similar to Recompose.

Let's Get Started

Prerequisites:

• React >= 16.8.0
• yarn or npm

Install (choose preferable way)

• yarn add react-hooks-combine
• npm install react-hooks-combine

Then...

import React from 'react'

import { withState, pipe, withCallbacks } from 'react-hooks-combine'

const useCount = pipe(
  withState('count', 'setCount', 0),
  // try to not forget about dependencies since it's hooks, not a hocs
  withCallbacks({
    increment: ({ count, setCount }) => () => setCount(count + 1),
    decrement: ({ count, setCount }) => () => setCount(count - 1),
  })
)

function Counter() {
  const { count, increment, decrement } = useCount()

  return (
    <div>
      <button onClick={decrement}>-1</button>
      {count}
      <button onClick={increment}>+1</button>
    </div>
  )
}

export default Counter

OR

import { pipe, withAsyncEffect, withCallbacks } from 'react-hooks-combine'

const useCurrentUser = pipe(
  withContext('repository', RepositoryContext),
  withAsyncEffect({
    deps: [],
    dataName: 'details',
    loadingName: 'loading',
    async asyncAction({ repository } /* state */, props) {
      const { userRepository } = repository
      const details = await userRepository.getCurrentUser()
      return details
    }
  }),
  // check withCallbacks section for syntax
  withCallbacks({
    onDelete: () => () => {
      ...
    },

    onUpdate: {
      deps: [...],
      func: () => () => {},
    },
  }, [...]),
)

export const UserView = (props) => {
  // useCurrentUser is a custom hook
  // and returns object which contains properties:
  // details, onDelete, onUpdate, loading, repository
  // details contains info that comes from some external source by async request
  const user = useCurrentUser(props)

  return (
    <div>
      <h2>Hello {user.details.firstName</h2>
      ...
      <button click={user.onUpdate}>Update</button>
      <button click={user.onDelete}>Delete</button>
    </div>
  )
}

OR

// component.jsx
import React from 'react'

export const UserPageComponent = ({ loading, userData, onSubmit, onCancel }) => (
  <div>
    <h2>User Form</h2>
    <ContentLoadIndicator loading={loading}>
      {
        () => (
          <UserForm 
            initialValues={userData}
            onSubmit={onSubmit}
            onCancel={onCancel} />
        )
      }
    </ContentLoadIndicator>
  </div>
)

// container.js (withAsyncEffect + withCallbacks)
import { combine, withAsyncEffect, withCallbacks } from 'react-hooks-combine'

import { UserPageComponent } from './component'

export default combine(
  withAsyncEffect({
    deps: ['userId'], // will request again if user id is changed
    dataName: 'userData', // 'data' by default
    asyncAction: (_state, ownProps) => ownProps.userService.load(ownProps.userId),
  }),
  withCallbacks({
    onSubmit: (state, props) => async (formData) => {
      const { userData } = state
      const { userService } = props

      await userService.save({ ...userData, ...formData})
      ...
    },

    onCancel: () => () => {
      ...
    }
  }, ['userData'])
)(UserPageComponent)

OR

// component.jsx
import React from 'react'

export const CounterComponent = ({ count, onPlus, onMinus }) => (
  <div>
    <strong>Active: {count}</strong>
    <button type="button" onClick={onPlus}>+</button>
    <button type="button" onClick={onMinus}>-</button>
  </div>
)

// container.js (withReducer + withCallbacks)
import { combine, withReducer, withCallbacks } from 'react-hooks-combine'

import { CounterComponent } from './component'

const INC = 'INC'
const DEC = 'DEC'

const reducer = (count, action) => {
    switch(action.type) {
      case INC: return count + 1
      case DEC: return count - 1
      default: return count
    }
}

export default combine(
  withReducer({
    reducer,
    stateName: counterState,
    initialState: 0,
  }),
  withCallbacks({
    onPlus: ({ counterState, dispatch }, _props) => () => {
      dispatch({ type: INC })
    },

    onMinus: ({ counterState, dispatch }, _props) => () => {
      dispatch({ type: DEC })
    }
  }, ['counterState']), // <-  deps for useCallback (CHECK API TO LEARN MORE)
)(CounterComponent)

OR

// container.js (withState + withCallbacks)
import { combine, withState, withCallbacks } from 'react-hooks-combine'

import { CounterComponent } from './component'

export default combine(
  withState('count', 'setCount', 0),
  withCallbacks({
    onPlus: ({ count, setCount }, _props) => () => {
      setCount(count + 1)
    },

    onMinus: ({ setCount }, _props) => () => {
      setCount(count => count - 1) // function could be used
    }
  }, ['count']), // <-  deps for useCallback (CHECK API TO LEARN MORE)
)(CounterComponent)
