Redux Actions - Without declaring CONSTANTS and action-creator functions for each action

#redux #react #javascript #lib

Actions Creator

You can find the full documentation on the https://actions-creator.js.org

Description

actions-creator is an awesome javascript package that allows you to dynamically create action objects in Redux without having to declare CONSTANTS and separate action-creator functions for each action.

Installation 

npm install actions-creator
Enter fullscreen mode Exit fullscreen mode

Usage Example 

import {actionsCreator} from 'actions-creator'

const action_1 = actionsCreator.MY.FIRST.ACTION('arg1')
//      {
//          type: 'MY/FIRST/ACTION',
//          payload: 'arg1',
//      } 

const action_2 = actionsCreator.This.is.my.second.action(2021)
//      {
//          type: 'This/is/my/second/action',
//          payload: 2021,
//      } 


// To get the type of action
String( actionsCreator.MY.FIRST.ACTION ) // 'MY/FIRST/ACTION'
// or
actionsCreator.MY.FIRST.ACTION().type // 'MY/FIRST/ACTION'
Enter fullscreen mode Exit fullscreen mode

Actions With Callback

Sometimes we need the action to have callback capability. It might be necessary in many cases.

Actions Creator allows us to do this in a beautiful way:
When we try to generate an action object, we can pass the callback function as the last argument. Actions Creator will check and if the last argument is a function, it will be considered as a callback function.

import {actionsCreator} from 'actions-creator'

const callback = () => {
    console.log('Hello, I am callback!!!')
}

const action = actionsCreator.MY.CALLBACKABLE.ACTION(123, callback)
//      {
//          type: 'MY/CALLBACKABLE/ACTION',
//          payload: 123,
//          cb: [Function callback],
//      }

action.cb() // 'Hello, I am callback!!!'
Enter fullscreen mode Exit fullscreen mode

Syntax

actionsCreator.ANY.ACTION(payload, callback?)

  • payload <Any> Any value as a payload.
  • callback <Function> Any function as a callback.

Returns <Object>

  • type <String> Action type as a string.

    actionsCreator.ANY.ACTION().type === 'ANY/ACTION' // true

  • payload <Any>

    The value of the payload - given in the first argument.

    actionsCreator.ANY.ACTION(123).payload === 123 // true

  • cb <Function>

    The function of the callback - given in the last argument.

    const callback = () => {};

actionsCreator.ANY.ACTION(123, callback).cb === callback // true

Pretty sure this has come up in prior threads, but:

the right answer is to use our official Redux Toolkit package and its createSlice API, which automatically generates action creators for each case reducer function that you write:

import { createSlice } from '@reduxjs/toolkit'

const todosSlice = createSlice({
  name: 'todos',
  initialState: [],
  reducers: {
    todoAdded(state, action) {
      state.push({
        id: action.payload.id,
        text: action.payload.text,
        completed: false
      })
    },
    todoToggled(state, action) {
      const todo = state.find(todo => todo.id === action.payload)
      todo.completed = !todo.completed
    }
  }
})

export const { todoAdded, todoToggled } = todosSlice.actions
export default todosSlice.reducer
Enter fullscreen mode Exit fullscreen mode

Or you can just use TypeScript :)
