Is this the right approach to create a component? - vue.js

Question

I made a view to show some contact information for the user:
<template>
<div v-for="user in users" class="user">
<div class="userInformation">
<img :src="user.photo" />
<div class="userName">
<h3>{{ user.age }}</h3>
<p>{{ user.gender }}</p>
</div>
</div>
<div class="button-wrapper">
<a href="#">
<button #click="$router.push(`/user/${user.id}`)">User Profile</button>
</a>
</div>
</div>
</template>
<style>
</style>
users is an array that holds all users which I fetch from the backend.
I want to create a component so that I can re-use the user card in other classes and don´t have to include the markup. I tried it the following way but I'm stuck at the button to redirect the user and the img because I don´t know how to use named slots there.
<template>
<div class="user">
<div class="userInformation">
<img />
<div class="userName">
<h3>{{ age }}</h3>
<p>{{ gender }}</p>
</div>
</div>
<div class="button-wrapper">
<a href="#">
<button>User Profile</button>
</a>
</div>
</div>
</template>
<script>
export default {
name: "UserCard",
props: [
"age",
"gender"
]
};
</script>
Another problem is that I have to re-create the fetch method for my users in other classes to access the user information. Would there be a better way of doing this?
// fetch user data from backend and create users array
...
<div v-for="user in users" :key="user.name">
<UserCard
:age="`${user.age}`"
:gender="`${user.gender}`"
/>
</div>
Is this the right approach to create a reusable component?

Answer 1

You're headed in the right direction for your component. If you wanted a named slot for the button you could use something like this.
Child Component
<template>
...
<slot name="button">
<!-- default/fallback content can be provided, if the parent does
not provide slot content the button-wrapper div will appear -->
<div class="button-wrapper">
<a href="#">
<button>Default Button</button>
</a>
</div>
</slot>
</div>
</template>
Parent
<div v-for="user in users" :key="user.name">
<UserCard
:age="user.age"
:gender="user.gender">
<template v-slot:button>
<div>some custom button here {{ user.phone }}</div>
</template>
</UserCard>
</div>
Also compilation scope (Vuejs v2 guide) is an important thing to keep in mind with slots - "Everything in the parent template is compiled in parent scope; everything in the child template is compiled in the child scope."
In terms of fetching your users, that's a separate issue. Look into something like Vuex or other ways of managing shared state if you find yourself constantly having to fetch users in various components
