Error TS2339: Cannot find property 'posts' in the given type

This is my code where I am attempting to make an API call in Ionic 5 using Axios

import axios from "axios";

import {
  IonCard,
  IonCardContent,
  IonCardSubtitle,
  IonCardTitle
} from "@ionic/vue";

export default {
  name: "Tab1",
  components: {
    IonCard,
    IonCardContent,
    IonCardSubtitle,
    IonCardTitle
  },
  data() {
    return { posts: [] };
  },

  created() {
    axios.get("http://gautammenaria.com/wp-json/wp/v2/posts").then(response => {
      this.posts = response.data;
    });
  }
};

Encountering the following error (Although data is being retrieved as expected )

TS2339: Property 'posts' does not exist on type '{ name: string; components: {

Uncertain about the issue

Answer №1

To ensure type inference, it is recommended to construct your component using the defineComponent function:

import axios from "axios";

import {
  IonCard,
  IonCardContent,
  IonCardSubtitle,
  IonCardTitle
} from "@ionic/vue";

import {defineComponent} from 'vue'

export default defineComponent({
  name: "Tab1",
  components: {
    IonCard,
    IonCardContent,
    IonCardSubtitle,
    IonCardTitle
  },
  data() {
    return { posts: [] };
  },

  created() {
    axios.get("http://gautammenaria.com/wp-json/wp/v2/posts").then(response => {
      this.posts = response.data;
    });
  }
});
