Configuring Vuex State

Question

Configuring Vuex State

Currently, I have a prop that is being bound to a child component. My goal is to eliminate this binding and instead assign the value to a data property in a vuex global state.

<VideoPip :asset="asset" v-show="pipEnabled === true" />

I am wondering how I can assign this.$store.state.assetVideo;, which is initially an empty object, to the asset value. Should I do this within a computed property?

To access the video state data, simply utilize the mapState helper. Here's an example implementation in your Video component:

import { mapState } from 'vuex'

export default {
  name: 'Video',
  computed: mapState(['assetVideo'])
}

You can then use this.assetVideo within your component's methods and assetVideo in its template. This setup will reactively update based on changes in the store.

When it comes to setting the value, mutations are essential. Here is a basic example of how you can define a mutation:

const store = new Vuex.Store({
  strict: true,
  state: {
    assetVideo: {}
  },
  mutations: {
    setVideoAsset: (state, assetVideo) => (state.assetVideo = assetVideo)
  }
}

Then, in your components, you can trigger this mutation like so:

methods: {
  selectVideo (video) {
    this.$store.commit('setVideoAsset', video)
  }
}

To implement this in your parent component:

// if you do not use a namespace
import { mapMutations, mapState } from 'vuex'

export default {
  computed: {
    ...mapState(['assetVideo']),
    asset: {
      get() {
        return this.assetVideo
      },
      set(newValue) {
        this.setAssetVideo(newValue)
      }
    }
  },
  methods: {
    ...mapMutations(['setAssetVideo']),
  }
}

Store setup:

const store = {
  state: {
    assetVideo: {}
  },
  mutations: {
    setAssetVideo(state, payload) {
      state.assetVideo = payload
    }
  }
}

In the parent component, you can update the state using this.asset = 'something' and it will reflect changes in the store and any other components utilizing it.

You can also pass this data to child components easily.
