`Muon` is a lightweight alternative to Electron written in Golang in about ~300 LoC, using Ultralight instead of Chromium. [Ultralight](https://ultralig.ht/) is a corss-platform WebKit rewrite using the GPU to target embeded desktop applications that resulted in a fast, lightweight, and low-memory HTML UI solution that blends the power of Chromium with the small footprint of Native UI.
# Features
- Full JS to Go interop
- GPU based rendering
- Cross-platform
- Hot-reloading
- Superior disk size + memory & cpu usage
| | Muon | Electron |
|:----:|---------|----------|
| CPU | 0.0% | 1.2% |
| MEM | 26.0 MB | 201.7 MB |
| SIZE | 42 MB | 136 MB |
# Example
From `examples/create-react-app/main.go`:
```go
package main
import (
"github.com/ImVexed/muon"
"cra-go/webfiles"
"net/http"
)
func main() {
// Any static asset packer of your liking (ex. fileb0x)
fileHandler := http.FileServer(webfiles.HTTP)
cfg := &muon.Config{
Title: "Hello, World!",
Height: 500,
Width: 500,
Hint: 2 | 4,
}
m := muon.New(cfg, fileHandler)
// Expose our `add` function to the JS runtime
m.Bind("add", add)
// Show the Window and start the Runtime
if err := m.Start(); err != nil {
panic(err)
}
}
// Muon automatically handles interop to and from the JS runtime
func add(a float64, b float64) float64 {
return a + b
}
```
# FAQ
## Q: *How are JS types translated to Go types?*
- JS: `Boolean` Go: `bool`
- JS: `Number` Go: `float64`
- JS: `String` Go: `string`
- JS: `Object` Go: `struct` via JSON
## Q: *I get `exit status 3221225781` when I try to run my program*
- Your program likely can't find the [Ultralight](https://ultralig.ht/) libraries. Ensure they're either installed on the system, or, in the same folder as your program.
