$wire.$js Syntax Changes in Livewire v4

February 01, 2026 • 1 min read • 16 views

Livewire v4 introduces a cleaner syntax for $wire.$js.

Before (v3 - Deprecated)

$wire.$js('bookmark', () => {
    // Toggle bookmark...
});

// Or
$js('bookmark', () => {
    // Toggle bookmark...
});

$wire.$js.bookmark = () => {
    // Toggle bookmark...
};

// Or in component
this.$js.bookmark = () => {
    // Toggle bookmark...
};

- Cleaner object-style syntax
- More intuitive naming
- Better IDE support
