Vue.js not displaying slot content

Currently, I am delving into the world of Vue and facing some challenges when it comes to grasping the concept of slots.

In my project, I have two components:

  1. BaseIcon
<template>
     ...
     <slot name="test"></slot> 
     ...
<template/>
  1. EventCard
<template>
  <router-link class="event-link" :to="{ name: 'event-show', params: {id: '1'}}">
      ..
      <BaseIcon name="users" slot="test">{{ event.attendees.length }} attending</BaseIcon>
      ..
  </router-link>
</template>

However, I am encountering an issue where the content inside the "slot" within the BaseIcon tags in EventCard is not being replaced as expected.

Answer №1

To utilize it effectively, you can make use of the v-slot attribute instead of the deprecated slot syntax as pointed out in this resource:

<BaseIcon name="users">
   <template v-slot:test>
    {{ event.attendees.length }} attending
   </template>
</BaseIcon>

Alternatively, you can opt for a shorthand notation:

<BaseIcon name="users" >
    <template #test>
    {{ event.attendees.length }} attending
   </template>
</BaseIcon>

Answer №2

Recently, I encountered a similar issue that puzzled me. It turned out that there was a small error in my HTML code (I forgot to close a bold tag). Surprisingly, the Vue script that translates the template HTML into JavaScript is highly sensitive to these types of errors, unlike browsers which are usually able to handle them without issue.

I had to go through a tedious process of elimination to pinpoint the mistake - removing sections of code and gradually adding them back until I found the culprit. There are likely syntax checkers available that can thoroughly analyze your template markup for any errors like this.

It's definitely worth looking into.

Answer №3

In templates, the v-slot can be specifically named, while defaults can also be utilized in components. For more information, refer to the documentation here.

Additionally:

It's important to note that v-slot is restricted to a single element (with one exception), unlike the outdated slot attribute. See further details here
