Simplify Your Svelte Deployments with svelte-bundle 🚀
Ever needed to deploy a Svelte component to a CMS that only accepts plain HTML files? Or wanted to create self-contained, distributable Svelte widgets? Meet svelte-bundle
- a CLI tool that converts your Svelte components into single HTML files.
The Problem 😫
We've all been there (at least I have). You're working with a legacy CMS or a system that only accepts HTML/CSS/JS files. You want to use Svelte's fantastic reactivity and component system, but the deployment constraints are holding you back. Writing vanilla JavaScript feels like going back to the stone age after experiencing Svelte's elegance.
Enter svelte-bundle 🎉
svelte-bundle
is a simple yet powerful CLI tool that lets you:
- Bundle a Svelte component into a single HTML file
- Include server-side rendering (SSR) for SEO benefits
- Optionally integrate Tailwind CSS
- Maintain Svelte's reactivity in the final bundle
Getting started is as simple as:
npx svelte-bundle -i your-component.svelte
How It Works 🛠️
Let's say you have a simple counter component:
<script>
let count = 0;
</script>
<main class="container mx-auto p-4">
<h1 class="text-2xl font-bold">Counter: {count}</h1>
<button
on:click={() => count++}
class="bg-blue-500 hover:bg-blue-700 text-white py-2 px-4 rounded"
>
Increment
</button>
</main>
Run svelte-bundle
, and you'll get a single HTML file with:
- Server-side rendered HTML
- Inlined, minified CSS
- Hydration-ready JavaScript
- All the Svelte reactivity you know and love
Why Use It? 🤔
- Legacy System Integration: Perfect for working with CMSs or platforms that only accept HTML files
- SEO-Friendly: Built-in SSR means your content is ready for search engines
- Simple Distribution: Share your Svelte components as standalone HTML files
- Modern Development: Use Svelte's modern features even in constrained environments
Getting Started 🚀
Basic usage:
# Install globally
npm install -g svelte-bundle
# Or use with npx
npx svelte-bundle -i src/App.svelte
Want Tailwind CSS? Just add the --tw
flag:
svelte-bundle -i src/App.svelte --tw
Use Cases 💡
- CMS Integration: Add dynamic Svelte components to static CMS pages
- Widget Distribution: Create self-contained, embeddable widgets
- Quick Prototypes: Generate standalone demos of your components
- Legacy System Enhancement: Add modern UI features to older systems
Current Limitations ⚠️
It's worth noting that svelte-bundle
is best suited for:
- Individual components or small apps
- Situations where a single HTML file output is required
- Cases where you can't use full SvelteKit deployments
It's NOT designed for:
- Full SvelteKit applications
- Large-scale applications (due to bundle size)
- Complex routing scenarios

Wrapping Up 🎈
svelte-bundle
fills a specific niche in the Svelte ecosystem - making it possible to use Svelte's powerful features in environments that traditionally wouldn't support it. While it's not meant to replace SvelteKit or other full-featured build tools, it's a valuable addition to your toolbox when you need to deploy Svelte components in constrained environments.
It's also worth noting this is in very early development and there is still a lot more to work on.
