Vue.js is throwing a TypeError message stating that it is unable to read the property 'post' of undefined, despite the fact that vue-resource has been successfully

Alright, here's the issue:

  1. I'm encountering a TypeError and I can't figure out why.
  2. I have Vue-resource installed and imported Vue.use('vue-resource'); import {} from 'vue-resource'; in my main.js file.

I've tried importing it in different ways and searched for a solution without success.

The function is invoked after clicking a button

<button class="btn btn-primary" @click="submit()">Submit</button>
.

The "submit" function is as follows:


      this.$http
        .post("https://vue-http-20bf2.firebaseio.com/data.json", this.user)
        .then(
          response => {
            console.log(response);
          },
          error => {
            console.log(error);
          }
        );
    }

Answer №1

After some troubleshooting, I finally managed to figure it out.

The problem seemed to be related to the Vue and VueResource imports. I ended up having to re-import both libraries and explicitly tell Vue to use VueResource once again.

import Vue from 'vue'
import VueResource from 'vue-resource';
import App from './App.vue'

`Vue.use(VueResource);`

I want to emphasize that I had already attempted this approach before.

Within my App.vue file, you can find the following code snippet:

submit() {
      this.$http
        .post("https://vue-http-20bf2.firebaseio.com/data.json", this.user)
        .then(
          response => {
            console.log(response);
          },
          error => {
            console.log(error);
          }
        );
    }
