Question

What is the best way to transfer a string to a different Vue component?

Within my project, I have a masterData.js file that serves as a repository for my master data. This file retrieves data from my mongo db and distributes it to various components of the project. To facilitate this process, I have implemented a function within the masterData.js file to export a string:

/ ***************************** MUTATIONS
const mutations = {
exportColumns (payload) {
  Object.keys(payload[0]).map(x => { return x; });
 }
}

The 'payload' variable holds all the rows of data, with 'payload[0]' containing the column header names. The output of executing this code snippet is as follows:

["_id","businessAreaName","businessAreaDisplay","councilDisplay","councilID"]

My goal is to transfer these values to my masterData.vue file. Currently, the code in my masterData.Vue file looks like this:

importColumns () 
  {
  let payload = {
    vm: this,
    mutation: 'masterData/exportColumns'
  };
}

What additional steps should I take to verify whether the column names have been successfully received?

To access the data in your store from within a component, you can map the state to the component or map a getter to it. Mutations are responsible for modifying the state of the store when used by components or actions. Here's an example:

//masterData.js
// Assuming this module gets rolled up as 'masterdata' to the primary store
// Store for payload state
const state = {
  payload: null,
}

// Sets the payload value
const mutations = {
  setPayload (state, payload) {
    state.payload = payload
  }
}

// Retrieves only the columns
const getters = {
  getColumns (state) {
    return Object.keys(state.payload[0]).map(x => { return x; })
  }
}

export default {
  state,
  mutations,
  getters,
}

Then...

//masterData.vue
<template>
  //...
</template>

<script>
  import { mapGetters, mapState } from 'vuex'

  export default {
    computed: {
      // To get state from a store module, use a function like this
      ...mapState({
        payload: function(state) {
          return state.masterdata.payload
        },
      }),
      // Directly reference the method for getters
      ...mapGetters([
        'getColumns',
      ])
    },
  }
</script>
