Question

What is mapGetter helper??

Answer 1

The mapGetters is a helper that simply maps store getters to local computed properties.

For example, the usage of getters for todo app would be as below,

import { mapGetters } from 'vuex'

export default {
  computed: {
    // mix the getters into computed with object spread operator
    ...mapGetters([
      'completedTodos',
      'todosCount',
      // ...
    ])
  }
}
