The world of web development is constantly evolving, and keeping up with the latest tools and frameworks is essential. Laravel Livewire is a popular package in the Laravel ecosystem. Recently, Livewire 3 has been released. So, with the Livewire 3 Release, it is packed with exciting features that are sure to elevate the development experience for Laravel developers. In this blog post, we’ll take a look and explore the new features and improvements that Livewire 3 brings. Also, we will know how these enhancements can benefit you in your web development projects.
If you are new to Livewire then let’s quickly take a recap of Laravel Livewire.
An Introduction to Livewire
Let me quickly introduce Livewire if you are a complete beginner to this. Livewire is a package that simplifies the process of building dynamic web applications in Laravel using components. It’s an alternative to traditional JavaScript frameworks. Also, it provides real-time interactions without writing a single line of JavaScript. This makes it an attractive choice for PHP developers and Laravel enthusiasts.
What’s New in Livewire 3?
The Livewire 3 comes with some significant improvements and features. Therefore, it’s now better at recognizing the differences between things. Which means you can create features for your web applications more quickly. Additionally, there’s less repetitive code in Livewire because it’s working more closely with Alpine.js, a JavaScript framework.
This collaboration allows Livewire to use Alpine’s features like Morph and History. Some of the new capabilities in Livewire 3 became possible because they reorganized the code and gave more importance to Alpine.js.
Let’s dive into the exciting features and enhancements introduced in Livewire 3.
Livewire Scripts, Styles, and Alpine are Injected Automatically
In Livewire 3, a notable convenience for developers is the automatic import of scripts, styles, and Alpine.js. This means that you no longer need to manually include these dependencies in your Laravel application. Livewire 3 takes care of it for you. However, in the previous version (Livewire 2) you had to import these things manually in the Laravel blade file by adding the styles
@livewireStyles
@livewireScripts
So, It’s a time-saving feature that simplifies your workflow and enhances the developer experience. Also, it makes Livewire even more appealing for web development projects in the Laravel ecosystem.
So, when you install Livewire 3, you do not need to configure anything.

Now, let’s see the next interesting features in Livewire 3.
Alpine-based Core Features in Livewire 3
The Livewire core has been entirely rebuilt, with a greater reliance on Alpine.js. Hence, this revamp involves the comprehensive utilization of Alpine’s Morph, History, and other plugins. These contribute to enhanced capabilities in recognizing differences and accelerating the development of features. This restructuring serves to reduce redundancy between Livewire and Alpine. Also, it streamlines the addition of numerous new features to the framework with seamless integration.
As a result, Livewire users can now enjoy improved diffing capabilities and a faster development experience.
Introduced /** @js */ Annotation Features in Livewire 3
Before Livewire v3, when you did something in a Livewire component, it made the server do extra work. Just like asking for information. This was not needed for basic tasks on your web browser. For example, clearing a text field.
Now, with Livewire 3, it has a new feature called JavaScript support. This means you can do tasks related to JavaScript right in the Livewire Component file. This is good because it stops the server from doing unnecessary work. Hence you can now use JavaScript functions more easily in your components.

Locked Properties /** @locked */ Added
In Livewire v3, there’s a cool new thing called “locked properties.” These are like special properties that you can’t change from the front part of your website. If you want to lock a property, just put a comment /** @locked */ above it in your component. If anyone tries to change that locked property from the front part of the website, Livewire will stop them and show an error message.
In the previous version of Livewire, that was applicable by using the protected property.
Introduced Lazy Components
In Livewire v3, you can make a component wait to show up on the webpage until it’s needed. To do this, use a lazy attribute when you’re setting up the component. It won’t show right away but will only appear when you scroll to it. Livewire will then ask the server to show it. You can also put temporary content while you’re waiting by using the placeholder method in your component.
After that, we will talk about a new directive that was introduced in the Livewire 3 Release.
Teleport Directive Added
In the Livewire 3 release, there is a cool new Blade directive called @teleport. It lets you move a part of your webpage to a different place in the HTML code. This can be handy to prevent problems with the stacking order of elements, like modals and slideouts, etc.
Let’s see the next interesting feature is data accessing from parent to child component.

Access Parent Component’s Data and Methods Using $parent
In the Livewire v3, a novel feature emerges. This offers an enhanced method for tapping into a parent component’s data and methods. The introduction of the $parent property facilitates this interaction. As a result, this provides a streamlined avenue to invoke methods located in the parent component.
Effortless Reactivity with /** @prop */ Annotation
In the Livewire 3 release, if you want to pass data from a parent component to a child component and have it automatically updated when changed in the parent, you can use the /** @prop */ comment above the property in the child component. Therefore, this ensures that any updates made to the property in the parent component will reflect in the child component.
We will see these all features through examples in our upcoming Livewire 3 tutorials. So, that’s it for this post.
Conclusion
In conclusion, Livewire 3 introduces a range of exciting features and updates that enhance the overall development experience. Moreover, From locked properties and lazy loading for optimized performance to the convenient @teleport directive and improved parent-child communication with the $parent property, Livewire 3 empowers developers with more flexibility and control in building dynamic web applications. These additions not only streamline common tasks but also address potential challenges, making Livewire an even more powerful and user-friendly framework for modern web development. As developers delve into Livewire 3, they can take advantage of these features to create interactive and efficient applications with ease.
