Toast Notification in Laravel Livewire Tutorial

What is Livewire?

Livewire is a full-stack framework for Laravel that makes building dynamic interfaces simple, without leaving the comfort of Laravel. Livewire relies solely on AJAX requests to do all its server communications. Livewire completely sends Ajax requests to do all its server-side communication without writing any line of Ajax script.

What is Toast Notification?

A toast notification is a message object that presents timely information, including confirmation of actions, alerts, and errors.

In most projects, We are use sweetalert2 for toast notifications. Sweetalert2 is very easy to use and implements in any frontend frameworks like Vue.js, React.js and etc.

We have already a project of Laravel Livewire Crud Example. so in this blog, we don't need to create a project for this example. Let's start with some basic steps.

Step 1: Clone Project

git clone https://github.com/suresh-ramani/larawire-crud-app.git

Step 2: Install Project Dependency

composer install

Step 3: Setup Database Detail

DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=<DATABASE NAME>
DB_USERNAME=<DATABASE USERNAME>
DB_PASSWORD=<DATABASE PASSWORD>

Step 4: Add Sweetalert2 script to home.blade.php

Put this toast notification code under @livewireScripts

<script src="//cdn.jsdelivr.net/npm/sweetalert2@10"></script>
<script>
    const Toast = Swal.mixin({
        toast: true,
        position: 'top',
        showConfirmButton: false,
        showCloseButton: true,
        timer: 5000,
        timerProgressBar:true,
        didOpen: (toast) => {
            toast.addEventListener('mouseenter', Swal.stopTimer)
            toast.addEventListener('mouseleave', Swal.resumeTimer)
        }
    });

    window.addEventListener('alert',({detail:{type,message}})=>{
        Toast.fire({
            icon:type,
            title:message
        })
    })
</script>

Step 5: Dispatch Event From Livewire Component

Livewire allows firing browser window events from components.

<?php

namespace App\Http\Livewire;

use Livewire\Component;
use App\Models\Category as Categories;

class Category extends Component
{
    public $categories, $name, $description, $category_id;
    public $updateCategory = false;

    protected $listeners = [
        'deleteCategory'=>'destroy'
    ];

    // Validation Rules
    protected $rules = [
        'name'=>'required',
        'description'=>'required'
    ];

    public function render()
    {
        $this->categories = Categories::select('id','name','description')->get();
        
        return view('livewire.category');
    }

    public function resetFields(){
        $this->name = '';
        $this->description = '';
    }

    public function store(){
        // Validate Form Request
        $this->validate();

        try{
            // Create Category
            Categories::create([
                'name'=>$this->name,
                'description'=>$this->description
            ]);
    
            // Set Flash Message
            $this->dispatchBrowserEvent('alert',[
                'type'=>'success',
                'message'=>"Category Created Successfully!!"
            ]);

            // Reset Form Fields After Creating Category
            $this->resetFields();
        }catch(\Exception $e){
            // Set Flash Message
            $this->dispatchBrowserEvent('alert',[
                'type'=>'error',
                'message'=>"Something goes wrong while creating category!!"
            ]);

            // Reset Form Fields After Creating Category
            $this->resetFields();
        }
    }

    public function edit($id){
        $category = Categories::findOrFail($id);
        $this->name = $category->name;
        $this->description = $category->description;
        $this->category_id = $category->id;
        $this->updateCategory = true;
    }

    public function cancel()
    {
        $this->updateCategory = false;
        $this->resetFields();
    }

    public function update(){

        // Validate request
        $this->validate();

        try{

            // Update category
            Categories::find($this->category_id)->fill([
                'name'=>$this->name,
                'description'=>$this->description
            ])->save();

            $this->dispatchBrowserEvent('alert',[
                'type'=>'success',
                'message'=>"Category Updated Successfully!!"
            ]);
    
            $this->cancel();
        }catch(\Exception $e){
            $this->dispatchBrowserEvent('alert',[
                'type'=>'error',
                'message'=>"Something goes wrong while updating category!!"
            ]);
            $this->cancel();
        }
    }

    public function destroy($id){
        try{
            Categories::find($id)->delete();
            $this->dispatchBrowserEvent('alert',[
                'type'=>'success',
                'message'=>"Category Deleted Successfully!!"
            ]);
        }catch(\Exception $e){
            $this->dispatchBrowserEvent('alert',[
                'type'=>'success',
                'message'=>"Something goes wrong while deleting category!!"
            ]);
        }
    }
}

Step 6: Run Project
