如何更改 jquery Deferred 以使用 Vue nexttick？

Question

I need to change this as I have read nextTick is a better option compared to deferred.

This is the original code that works well:

methods: {
    ...mapActions(['fetchOverdraftLogs', 'setOverdraftFilters', 'fetchUserEventsCsvFile']),
},
  computed: {
    ...mapGetters(['getOverdraftLogs'])
  },
...
        loadData: filters => {
          const d = $.Deferred()
          this.fetchOverdraftLogs({ params: this.filtersToSend(filters) })
            .then(res => {
              d.resolve(this.getOverdraftLogs)
              this.setFilterValues()
            })
          return d.promise()
        })
        }

However, I am not able to rework this with nextTick:

loadData: filters => {
  this.fetchOverdraftLogs({ params: this.filtersToSend(filters) })
  this.$nextTick(() => {
    this.setFilterValues()
    this.getOverdraftLogs
  })
}

I need to make sure for the grid that after the API is called it reads the data from the state.

Could you assist?

Deferred pattern is generally an antipattern, especially with ES promises. It's not an alternative to nextTick . Promises are already asynchronous, a promise that is instantly resolved provides a small delay. nextTick provides a delay that is big enough DOM to be updated.

nextTick supports promises but here it's not needed.

It should be:

    loadData: filters => {
      return this.fetchOverdraftLogs({ params: this.filtersToSend(filters) })
        .then(() => {
          this.setFilterValues()
          return this.getOverdraftLogs;
        })
    }

Vuex actions aren't supposed to return data they operate on, so there should be no res .
