Solution to error encountered when using vuelidate in quasar: "ReferenceError: process is not defined"

Question

I am building an application using Quasar framework. For form validation I am using vuelidate for validation.

Quasar version:

» Quasar Pkg... v2.0.3

» Pkg @quasar/app... v3.0.3

verify:

"vuelidate":"^0.7.6"

"Similar" code that basically works in another Quasar 1.X application, but fails in Quasar 2.x:

Boot configuration:

import Vuelidate from 'vuelidate';

export default ({ app }) => {
  app.use(Vuelidate);
};

Components:

<template>
  <div>
    <q-input
      filled
      label="Tweets"
      type="text"
      v-model="$v.tweets.$model"
      :error="$v.tweets.$error"
      @blur="$v.tweets.$touch"
    />
  </div>
</template>

<script>
import { defineComponent } from "vue";
import { required, numeric } from "vuelidate/lib/validators";

export default defineComponent({
  name: "StatsForm",
  data() {
    return {
      tweets: null,
    };
  },
  validations: {
    tweets: { required, numeric },
  },
});
</script>

Code for using components:

<template>
  <q-page class="flex justify-center q-ma-md">
    <div class="column">
      <h1>Twitter Profile Performance Report</h1>
      <stats-form />
    </div>
  </q-page>
</template>

<script>
import { defineComponent } from "vue";
import StatsForm from "../components/StatsForm.vue";

export default defineComponent({
  name: "PerformanceReport",
  components: {
    "stats-form": StatsForm,
  },
});
</script>

<style>
h1 {
  font-size: 2.5em;
  font-weight: 400;
  line-height: 1em;
}
</style>

I get the following error in my browser:

vue-router.esm-bundler.js?f6c4:3248 ReferenceError: process is not defined

Answer 1

Vuelidate v0.7.6 is the version released on October 23, 2020, and is only compatible with Vue 2. You are using Vue 3, which means you mustuse Vuelidate v2
