Laravel Livewire CRUD Application Tutorial Part 2

In the second part of this tutorial, we will display all the tasks on the home page, and later we will add the links so the user can create, update, and delete tasks.

Create the Tasks component

First, let's create the Tasks component. Run the command:

php artisan make:livewire Tasks

Once done, inside "app/Livewire/Tasks.php" add the following code:

                                                                                                          
<?php

namespace App\Livewire;

use App\Models\Task;
use Livewire\Attributes\Validate; 
use Livewire\Component;
use Livewire\WithPagination;

class Tasks extends Component
{
    use WithPagination;

    #[Validate('required',message:'Please provide the task details.')] 
    public $body = '';
    public $taskToUpdate = null;
    public $updating = false;

    public function storeTask()
    {
        $validated = $this->validate();
        Task::create($validated);
        $this->clearData();
    }

    public function editTask(Task $task)
    {
        $this->resetValidation();
        $this->body = $task->body;
        $this->taskToUpdate = $task;
        $this->updating = true;
    }

    public function updateTask()
    {
        $validated = $this->validate();
        $this->taskToUpdate->update($validated);
        $this->clearData();
    }

    public function taskDone()
    {
        $this->taskToUpdate->update([
            'done' => 1
        ]);
        $this->clearData(); 
    }

    public function deleteTask(Task $task)
    {
        $task->delete();
        $this->clearData();
        return redirect('/');
    }

    public function clearData()
    {
        $this->body = '';
        if($this->updating) {
            $this->taskToUpdate = null;
            $this->updating = false;
        }
        $this->resetValidation();
    }

    public function render()
    {
        return view('livewire.task',[
            'tasks' => Task::latest()->simplePaginate(3)
        ]);
    }
}

Display all the tasks

Next, inside "resources/views/livewire/tasks.blade.php" add the following code:

                                                                                                                  
<div class="container">
    <div class="row my-5">
        <div class="col-md-10 mx-auto">
            <div class="row my-5">
                <div class="col-md-4">
                    <div class="card">
                        <div class="card-body">
                            @if ($tasks->count())
                                <ul class="list-group">
                                    @foreach ($tasks as $task)
                                        <li 
                                            wire:key="{{$task->id}}"
                                            class="list-group-item d-flex justify-content-between align-items-center">
                                            <p @class(['text-decoration-line-through' => $task->done])>
                                                {{ $task->body }}
                                            </p>
                                            <div class="dropdown ms-auto">
                                                <i class="fa-solid fa-ellipsis-vertical"
                                                    data-bs-toggle="dropdown"
                                                    style="cursor: pointer"
                                                    ></i>
                                                <ul class="dropdown-menu">

Add routes

Next, inside "routes/web.php" add the following code:

Download the source code from here.

                                                                                                                  
<?php

use App\Livewire\Tasks;
use Illuminate\Support\Facades\Route;

Route::get('/', Tasks::class);
