Reusable File Upload Component With Laravel Livewire and AlpineJS

Mithicher Baro — Sun, 03 Jan 2021 16:28:23 +0000

Laravel Livewire makes file uploading very easy, it's almost like magic to say. Here we will see how to create a modular upload component with the help of laravel blade component.

This post assumes you have a basic knowledge of Laravel Livewire and AlpineJS and have already installed a fresh copy of it along with Laravel.

Features it will include are:

Upload Component - both single and multiple files
Show progress when uploading
Show preview of the uploaded file
Validation
Remove already uploaded file

Let us create a Livewire component SingleUpload

php artisan livewire:make SingleUpload

After running this command two files will be generated in app/Http/Livewire and resources/views/livewire directory respectively.

SingleUpload.php : The component class to handle our logic
single-upload.blade.php : The view file for our component

SingleUpload.php

use Livewire\WithFileUploads;

class SingleUpload extends Component
{
    use WithFileUploads;

    public $photo;

    public function render()
    {
        return view('livewire.single-upload');
    }
}

How to use in Laravel Blade Views

For single image upload the blade component will look like this:

<x-file-attachment wire:model="photo" :file="$photo" />

For multiple image upload the blade component will look like this:

<x-file-attachment wire:model="photo" :file="$photo" multiple />

For profile image upload the blade component will look like this:

<x-file-attachment 
    wire:model="photo" 
    :file="$photo" 
    mode="profile" 
    profile-class="w-24 h-24 rounded-lg" 
    accept="image/jpg,image/jpeg,image/png"
/>

The full component is given below:

@props([
    'file' => null,
    'accept' => 'image/jpg,image/jpeg,image/png,application/pdf',
    'multiple' => false,
    'mode' => 'attachment',
    'profileClass' => 'w-20 h-20 rounded-full'
])

<div x-data="{ 
    isMultiple: Boolean('{{ $multiple }}') || false, 
    progress: 0,
    isFocused: false,
    handleFiles() { 
        if (this.isMultiple === true) {
            @this.uploadMultiple('{{ $attributes->wire('model')->value }}', this.$refs.input.files, () => {
            }, () => {
            }, (event) => {
                this.progress = event.detail.progress || 0
            })
        } else {
            @this.upload('{{ $attributes->wire('model')->value }}',  this.$refs.input.files[0], () => {
            }, () => {
            }, (event) => {
                this.progress = event.detail.progress || 0
            });
        }
    }
}"
x-cloak>
    @if(! $file || $mode === 'profile')
        @php $randomId = Str::random(6); @endphp
        <label for="file-{{ $randomId }}" class="relative block leading-tight bg-white hover:bg-gray-100 cursor-pointer inline-flex items-center transition duration-500 ease-in-out group overflow-hidden

        wire:loading.class="pointer-events-none"
