Build Desktop Apps Fast with TypeScript and Electrobun
If you've ever wanted to build a desktop application but felt bogged down by the usual suspects—Electron's bundle size, platform-specific toolchains, or just the general overhead—there's a new option on the block. Electrobun offers a fresh take: letting you build ultra-fast, tiny, and cross-platform desktop apps using TypeScript.
It promises a developer experience that feels modern and lightweight, aiming to cut through the typical friction of desktop development. Let's see what it's about.
What It Does
Electrobun is a framework for building native desktop applications. At its core, it uses Bun as its JavaScript runtime and Tauri for the native application shell and window management. You write your application logic in TypeScript, and Electrobun handles the rest, compiling it down to a small, performant binary for Windows, macOS, and Linux.
The key is the combination: Bun brings incredible speed to the TS execution and bundling, while Tauri ensures the final app is lean by using the system's webview instead of shipping an entire browser engine.
Why It's Cool
The appeal of Electrobun comes down to a few specific points:
- Seriously Small Binaries: Because it leverages the OS's existing webview (like WebKit on macOS), the final application package can be orders of magnitude smaller than a comparable Electron app. We're talking megabytes, not hundreds of megabytes.
- TypeScript-First: It's built for TypeScript developers. You get type safety and a modern dev experience out of the box without extra configuration.
- Performance: Bun is famously fast for startup and execution. This translates to your app feeling snappier, both during development and for your end-users.
- Simplified Workflow: It abstracts away much of the complexity of combining native backends with frontend code. You can focus on building your app's features rather than the build pipeline.
In short, it's for developers who want the UI flexibility of web tech (HTML/CSS/JS) for their desktop app but need the resulting binary to be efficient and respectful of system resources.
How to Try It
Ready to kick the tires? The project is on GitHub. The quickest way to get started is to clone the repository and run the example.
# Clone the repo
git clone https://github.com/blackboardsh/electrobun.git
cd electrobun
# Follow the setup instructions in the README
# This will typically involve installing Bun and then running the example.
Make sure you have Bun installed first. The project's README has detailed setup instructions to get the example application running on your machine. It's the best way to see the workflow and final app size for yourself.
Final Thoughts
Electrobun feels like a pragmatic step forward in the "web tech on the desktop" space. It doesn't try to reinvent the wheel but instead smartly combines two excellent, modern tools (Bun and Tauri) with a focused developer experience.
If you're prototyping a new desktop tool, want to ship a lightweight utility, or are just tired of massive node_modules folders in your desktop projects, this framework is worth a look. It might not be the fit for every single use case—especially if you need deep, specific native modules—but for a vast range of applications, it hits a sweet spot of productivity and performance.
