How to add view count in vue?

Question

I am building a post website in vue.

I want to implement the functionality so that people can see how many views ('vues') the post got.

Every time someone clicks on a post, the view count should increase by 1.

I use firebase as my backend.

This is my simplified code based on my question:

<template>
  <h1>{{ title }}</h1>
  <p>This page has {{ views }}</p>
</template>

<script>
export default {
    setup() {
        const title = "Blog 1"
        let views = 0

        return { title, views }
    }
};
</script>
