We Can All Agree 🤔

Let's face it—HTML file pickers are not the prettiest. Even Vuetify’s file-input component, while functional, is pretty basic and doesn’t offer an image preview, which isn't great for user experience.

Vuetify Slots to the Rescue 🚀

Luckily, Vuetify allows us to customize its components using slots. In this case, we can use slots to jazz up the label and create a more user-friendly experience.
So here's what we're building

The Concept 🎨

The concept here is to hide the file-input if the image is there and show the preview instead, and vice versa. as shown below

First we create two variables image (the file selected by the user) - imageUrl (we'll use it to render the image later).

The magic happens in the label slot, where we can enlarge the label and even add a text and icon right inside it!

Let's Customize the Component 🛠️ :

We can achieve this by playing around with the label slot. Check out the code below—it's all about adding some img and p tags. With a bit of CSS, we can make the label look larger and more appealing.

<template v-slot:label="{ isActive }">
          <div>
            <div class="img-input-label">
              <div class="img-upload-icon" v-if="!isActive.value">
                <v-icon icon="mdi-cloud-upload"></v-icon>
              </div>
              <div class="img-upload-text">
                <p>select an image to upload</p>
              </div>
            </div>
          </div>
        </template>

Let the User Pick 🎯

Now, let's allow the user to pick an image:

    <v-file-input v-if="!image" accept="image/*" 
        @change="selectImg" v-model="image" >
<!--the label slot goes here-->
      </v-file-input>

• v-model="image" binds the selected image to image variable.
• @change="selectImg" triggers the selectImg function when an image is chosen (more on that later).
• v-if="!image" hides the input if there's already an image selected.

Preview the Image 🖼️

Once the user picks an image, we hide the file-input and show a preview:

  <div v-if="image" class="image-preview">
      <img :src="imageUrl" alt="Your Image Preview" />
</div>

v-if="image" show the preview only if there is an image.
:src="imageUrl" img source to FileReader _{(refer to the source code)}

Your user is stuck 🤷

If the user wants to remove or replace the image, we can easily add a delete button on top of the preview:

 <v-icon
        class="remove-icon"
        @click="clearImage"
      >
        mdi-close-circle-outline
      </v-icon>

• @click="clearImage" : when the icon is pressed we call a function that clears the image.
