<template>
  <div id="app">
    <label>Password</label>
    <input type="password" v-model="password" />
    <span v-if="score === 0">Use better password</span>
    <password-meter @score="onScore" :password="password" />
  </div>
</template>

<script>
import { defineComponent, ref } from "vue";
import PasswordMeter from "vue-simple-password-meter";

export default defineComponent({
  name: "App",
  components: {
    PasswordMeter,
  },
  setup() {
    const password = ref("");
    const score = ref(null);

    const onScore = (payload) => {
      console.log(payload.score); // from 0 to 4
      console.log(payload.strength); // one of : 'risky', 'guessable', 'weak', 'safe' , 'secure'
      score.value = payload.score;
    };

    return {
      password,
      onScore,
      score,
    };
  },
});
</script>

Motivation

Since Every other components and libraries mostly were using zxcvbn was 799.5kb minified and 388.3kb minified and Gzipped, so I decided to make simpler approach and use regex instead of dictionary for validating.
