Vuetify's paginated server-side datatable does not support client-side sorting

The Challenge

The issue I am facing revolves around using a server-side paginated datatable. Specifically, when utilizing the Vuetify data tables component and attempting to perform client-side sorting due to using a public API that I did not develop, the default sorting functionality of the component fails to work.

I'm left questioning whether achieving client-side sorting is even feasible, especially since the documentation only provides an example of pagination and sorting being handled server-side.

Below is the code snippet for my component:

<v-data-table
          :headers="datapointHeaders"
          :items="datapoints"
          :items-per-page="datapointsPerPage"
          :server-items-length="datapointsTotalItems"
          :loading="loading"
          :loading-text="'Loading datapoints ...'"
          :options.sync="options"
          :footer-props="footerProps"
        >
          <template v-slot:item.health="{ item }">
            <StatusLamp
              :color="item.health"
              :classes="'ml-2'"
            />
          </template>
          <template v-slot:item.attributes="{ item }">
            <v-btn
              outlined
              small
              color="blue"
              @click="showAttributes(item)"
              class="mb-1 mr-1 mt-1"
            >details</v-btn>
          </template>
        </v-data-table>

In the JavaScript part:

private options: any = {
  itemsPerPage: this.datapointsPerPage,
  page: this.datapointsCurrentPage,
};

@Watch('options.page')
onPageChange(value: number, oldValue: number): void {
  this.fetchDatapoints(value, this.options.itemsPerPage);
}

@Watch('options.itemsPerPage')
onPerPageChange(value: number, oldValue: number): void {
  this.fetchDatapoints(this.page, value);
}

get loading(): boolean {
  return get(this.$store.getters.getDatapoints, ['loading'], true);
}

<!-- Additional code snippets have been slightly altered for uniqueness -->

<h2>UPDATE</h2>

<p>Upon further investigation, I discovered that by removing the <code>server-items-length property from the v-data-table component, client-side sorting functions properly. However, this results in the loss of total item count information, displaying only the current items per page as the maximum limit for item count.

Answer №1

After further investigation

After reaching out to the #vuetify-help channel on the official Vuetify Discord server for assistance with client-side pagination and sorting while using server-items-length, I discovered that these features are disabled in such cases. The same applies to search functionality.

Furthermore, during my research, I came across a related issue involving search and server-side pagination: https://github.com/vuetifyjs/vuetify/issues/3475#issuecomment-370566804

Conclusion

It became apparent that utilizing client-side sorting and filtering on server-side paginated data is not practical, as it would only apply to the current page's data set.
