vue-ya-stash

Yet Another simple stash storage for Vue

TL;DR

npm install vue-ya-stash

export default {
  stash: ['user', 'ui'],
  mounted () {
    console.log('this.user.name')
    this.$emit('update:user', {...this.user, name: 'Bob'})
    this.$emit('patch:ui', 'sidebar.visible', true )
  }
}  

Design Goals

1. Not too complicated
2. Not too simple
3. Try to keep the standard pattern (props-emit)

#3 is being specially concerned. As you see from example, one can effortlessly switch between props-emit and stash model. Furthermore ways of universal components for two models will be supported. I wish :)

Usage

Install

npm install --save vue-ya-stash

Setup

import Vue from 'vue'
import stashStore from './stash'

new Vue({
  el: '#app',
  router,
  stashStore,
  template: '<App/>',
  components: { App }
})

./stash/index.js

import Vue from 'vue'
import VueYaStash from 'vue-ya-stash'

Vue.use(VueYaStash)

var stash = {
  user: {
    name: 'Ted',
    email: 'ted@example.com'
  },
  ui: {
    sidebar: {
      visible: true
    }
  }
}

var stashContainer = new Vue({
  data: {
    stash: stash
  }
})

export default stashContainer.stash

Component

Vue.component('user-card', {
    stash: ['user', 'ui'],
    created () {
      // Access
      console.log(this.user.name)
      // Update
      this.$emit('update:user', {...this.user, name: 'Bob'})
      // Patch
      this.$emit('patch:user', 'name', 'Bob')
    }
});

Vue.component('user-card', {
    stash: {
      name: 'user.name',
      sidebar: 'ui.sidebar'
    }
    created () {
      // Access
      console.log(this.name)
      console.log(this.sidebar.visible)
      // Update
      this.$emit('update:name', 'Bob')
      this.$emit('update:sidebar', {...this.sidebar, visible: true})
      // Patch
      this.$emit('patch:sidebar', 'visible', true)
    }
});

Patch

To update parts of stash, one can use patch instead of update

this.$emit('patch:key', path_string, update_value)

For example after you mounted stash.ui from above, you can change stash.ui.sidebar.visible with patch

Vue.component('nav-bar', {
  stash: ['ui']
  methods: {
    toggleSidebar () {
      this.$emit('patch:ui', 'sidebar.visible', !ui.sidebar.visible)
    }
  }
}

A path string can cover dot(.) references and also square brackets('[]').

this.$emit('patch:ui', 'sidebar.menu[4].content', 'new value')

Path strings should be same as what one does with real javascript syntex.

You can't do

this.$emit('patch:menu', 1, 'new value')

But you should do

this.$eimt(`patch:menu', '[1]', 'new value')

Path string is strictly parsed and will throw errors in advance.
