How it works

Bundle facilitates JavaScript imports inside Blade using Bun.

Bun does all the heavy lifting and Bundle provides the glue between Blade and injects your imports on the client side.

The component processes your import on the fly and renders a script tag in place.

<x-import module="apexcharts" as="ApexCharts" />

<!-- yields the following script -->

<script src="/x-import/e52def31336c.min.js" type="module" data-module="apexcharts" data-alias="ApexCharts"></script>

A bit more in depth

Bundle is meant as a tool for Blade centric apps, like Livewire, to enable colocation of page specific JavaScript inside Blade.

In contrary to how a JavaScript app would be bundled, this package creates tiny bundles usually only consisting of one module each. Depending on the props you pass to the <x-import /> component.

Bun treats these bundles as being separate builds. This would cause collisions with reused tokens inside the window scope, but since Bundle loads your imports via a script tag with type="module" the code is constrained to it’s own module scope.

A script tag with type="module" also makes it defer by default, so they are loaded in parallel & executed in order.

When you use the <x-import /> component Bundle constructs a small JS script that imports the desired module and exposes it on the page. It then bundles it up and caches it in the storage/app/bundle directory. This is then either served over http or rendered inline.

The _import helper function

Bundle’s core, which containst _import helper function and internal import map, is automatically injected on every page.

The _import function may be used to fetch the bundled import by the name you’ve passed to the as argument.

var module = await _import("lodash"); // Resolves the module's default export

The _import function accepts a optional export argument which defaults to ‘default’. When the module you’re exporting uses named exports, you may resolve it like this:

var module = await _import("lodash", "filter"); // Resolves a named export 'filter'

In cases like this it might be advantagious to use per-method imports instead. Please refer to the advanced usage example.


The _import function is async & returns a Promise. In order to use this in inline scripts you need to wrap it in a async function, or make the script tag you are using it in of type="module".

It’s recommended to use a inline script of type module. This makes it deferred by default & instructs the browser to run those tags sequentially. If you use a script without the module type you can still use Bundle, but with some extra boilerplate. Check here if you’d like to learn more

Refer to the local modules docs for a more detailed explanation on how the _import function can be utilized in different scenarios.


Bundle will throw exceptions when Laravel’s debug mode is enabled, but only raise console errors when it’s not. Read all about running Bundle in production environments.
