Tips for accessing an API and setting up data mapping for a data table in nuxt.js

I desperately need assistance. I have been struggling with this issue for a while now, but all my attempts have ended in failure. My objective is to retrieve API data that corresponds to an array containing name, id, and email, and then display this information in a data-table. Could someone please provide some guidance? Understanding this is crucial for the success of my new project. Please, lend me your expertise!

It is recommended to use string/number values as keys instead of non-primitive values.

    <template>
  <v-app>
    <v-data-table dense :headers="headers" :item="items" class="elevation-1">
      <tbody>
        <tr v-for="item in items" :key="items">
          <td>{{item.postId}}</td>
          <td>{{item.email}}</td>
          <td>{{item.name}}</td>
        </tr>
      </tbody>
    </v-data-table>
  </v-app>
</template>

<script lang="ts">
import { Component, Vue } from "nuxt-property-decorator";
import axios from "axios";

@Component
export default class AxiosPractice extends Vue {
  items: any[] = [];

  headers = [
    { text: "id", value: "postId" },
    { text: "name", value: "name" },
    { text: "email", value: "email" }
  ];
  async mounted() {
    const response = await axios.get(
      "https://jsonplaceholder.typicode.com/posts/1/comments"
    );
    this.items = response.data.map((comment:any) => ({
      postId: comment.postId,
      email: comment.email,
      name: comment.name
    }));
  }
}
</script>

Answer №1

It is recommended to use a primitive value like a string or number as the key in a v-for loop instead of an array or object. One simple solution is to use the loop index as the key:

<tr v-for="(item,index) in items" :key="index">

Furthermore, if you are utilizing the v-data-table component, you can simply do the following:

<v-data-table dense :headers="headers" :items="items" class="elevation-1">
    
    </v-data-table>

If you need to customize specific columns, please refer to this answer.
