Hello, fellow developers! 👋
In today's post, we're going to be tackling performance optimization of Laravel Livewire apps. If you've been using Laravel Livewire in your projects and experienced some performance issues, this blog is for you! 💡 So, let's dive straight in.
Prerequisite Knowledge 📚
Before we kick off, you should have a basic understanding of both Laravel and Livewire. Here are the installation commands for them:
composer require laravel/ui
composer require livewire/livewire
For a deep dive into these technologies, check out the Laravel documentation and the Livewire documentation.
Caching ⚡
As much as we'd like to believe otherwise, our server-side can feel the strain too. One method we can use to reduce the overhead is by using Laravel's in-built caching functionality. Here is an example of how to cache a Livewire component's data:
php artisan make:livewire counter
class Counter extends Component{
public $count;
public function mount(){
$this->count = Cache::get('count', 0);
}
public function increment(){
$this->count++;
Cache::forever('count', $this->count);
}
public function render(){
return view('livewire.counter');
}
}
The mount()
method fetches the cached count value from a cache. If there's no cache available, it defaults to 0.
Eager Loading 🚀
If a data set is dependent on another data set, you might end up with an N+1 problem. Thankfully, Laravel provides a solution to this issue with Eager Loading.
public function render(){
$users = User::with(['profile', 'posts'])->get();
return view('livewire.users', compact('users'));
}
In the code above, User::with(['profile', 'posts'])->get()
ensures that associated profile
and posts
data for the users gets fetched at the same time when fetching users. This can significantly reduce the number of queries your app makes to the database and speed things up. 🏎️

Remember, optimization is a continuous process and there's almost always some part of your app that could be made more efficient. Happy coding! 👨💻👩💻
Happy coding, until next time! 👋
