Vue-Redux-Mixin-Generator

A simple function that returns a reusable object of redux dispatch action functions thats pluggable to Vue's mixins option.

Installation

npm install --save vue-mixin-generator

Why Should I Use This?

I built this to help myself and others to reduce the amount of code necessary to get up and running with redux. I love the concept but I found it tedious to create actions, reducers and then have to create Vue methods that call the store.dispatch() method. Knowing how simple it was to import a plain object and plug it into Vue's mixins object, I decided to create this to generate reuseable methods that can be used all over an application.

Usage

A typical redux flow looks like:

Actions

export const SET_USER = 'SET_USER';
export const setUser = (user) => ({type: SET_USER, user});

export const CLEAR_USER = 'CLEAR_USER';
export const clearUser = (user) => ({type: CLEAR_USER, user});

export const UPDATE_USER_INFO = 'UPDATE_USER_INFO';
export const updateUser = (user) => ({type: UPDATE_USER_INFO, user});

Reducers

//Import all the actions
import * as actions from './actions';

function user(state = {}, action) {
	switch (action.type) {

		case actions.SET_USER:
			return {...state, ...action.user};

		case actions.CLEAR_USER:
			return action.user;

		case actions.UPDATE_USER_INFO:
			return {...state, ...action.user};

		default:
			return state
	}
}

Dilema

Now in all of your Vue files have:

import store from './services/store.js

import {setUser, updateUser} from './actions.js

and your Vue's methods options becomes full of functions that aren't reuseable anywhere else in your application.

EX:

data(){
  return {
    user: store.getState()
  }
},

methods: {
  setNewUser(user) {
    store.dispatch(setUser(user));
  },
  updateUserName(name) {
    store.dispatch(updateUser(name))
  }
}

Options

{
  prefix:  optional,
  actions: required, array of functions
  store:   required, Store Class
}

`import store from './services/store.js`

`import {setUser, updateUser} from './actions.js` 

// No Function Name Prefix
export const UserMixin = ({
  actions: [setUser, updateUser],
  store: store
})


// Prefixed Functions
export const UserMixin = ({
  prefix: 'store',
  actions: [setUser, updateUser],
  store: store
})

Solution

Create mixins that allow you to resuse methods that call store.dispatch() importable across your entire app.

// Store & Actions
import store from './store.js';
import {setUser, clearUser, updateUser} from './actions.js';

// Mixin Generator
import reVueMixinGen from 'reVueMixinGen';


/**
  Create New Mixin Object
*/
export const UserMixin = reVueMixinGen({
  prefix: 'store',
  actions: [setUser, clearUser, updateUser],
  store: store
})


/**
  Mixin Object Created
*/

UserMixin = {
    methods: {
      storeSetUser: function(...params) {
        store.dispatch(setUser(...params))
      },
      storeClearUser: function(...params) {
        store.dispatch(clearUser(...params))
      },
      storeUpdateUser: function(...params) {
        store.dispatch(updateUser(...params))
      }
    }
}

Using Together With Vue Component

import UserMixin from './mixins.js'

{
  template: require('./path/to/file.html'),
  mixins: [UserMixin]
  
  data () {
    return {
      user: store.getState(),
      error: ''
    }
  },
  
  // Now methods can be 100% focused on data manipulation
  methods: {
  
    changeName(name) {
      return name.length > 0 ? this.storeUpdateUser(name) : false
    },
    
    fetchUserProfile() {
      $http.get('api/user/profile')
        .then(res => this.storeUpdateUser(res.data))
        .then(err => this.error = err.data)
    }
  }
}

Verdict

Now you have the methods necessary for dispatching new states that is importable to any component. I know some might be confused on how i'm calling the methods I created from reVueMixinGen, When you attach a mixin to a component the methods become available via this just like any other method in the $vm scope.

EX:

import UserMixin from './mixins.js'
{
 template: require('./path/to/file.html'),
 mixins: [UserMixin],
 
 data() {
  return {
    user: {
      firstName: 'Sean',
      lastName: 'Parsons'
    }
  }
 },
 
 attached() {
    // this.storeSetUser is equivalent to:
    // store.dispatch(setUser(user))
    // Except without the import of both store.js and actions.js in each component.
    this.storeSetUser(this.user);
 }
}
