Seeking advice on how to incorporate an unread component before a dynamic message component within a v-for loop. The goal is to display an unread panel before any unread messages, indicating their status clearly.
Below is the sample code without the unread panel:
<template>
<div>
<Message v-for="(message, index) in messages" :key="index" :message="message></Message>
</div>
</template>
Objective:
The aim is to add an unread panel before displaying any unread messages. This should only be added once in the template, ensuring clarity for other developers reviewing the code.
How to Integrate Unread Panel
Method 1:
Directly include it in the main template.
<template>
<div>
<template v-for="(message, index) in messages" :key="index">
<Unread v-if="message.getId() === firstUnreadId"></Unread>
<Message :message="message"></Message>
</template>
</div>
</template>
Issue:
This method involves redundant checks in the DOM placement of the unread component, making it challenging for developers to understand that the unread component loads only once.
Method 2:
Embed the unread component alongside messages and insert an extra message into the array for loop processing.
<template>
<div>
<template v-for="(message, index) in messages" :key="index">
<Message :message="message"></Message>
</template>
</div>
</template>
<template>
<message :is="currentComponent"></message>
</template>
<script>
export default {
props: {
message
},
computed: {
currentComponent: function() {
switch (this.message.getType()) {
case "unread":
return "Unread";
// ...
}
}
}
}
</script>
Challenge:
The concept of treating Unread as a message appears forced and inefficient. Looking for alternative solutions or suggestions. Thank you!
