Superior to similar solutions. Doesn't use electron or cgo. Easy communication between Go and Js. Can easily use libs like React, Vue and Angular.
This is a demo app using GUI library https://github.com/zserge/lorca which requires only Chrome and might even work with Firefox in the future.
| package main | |
| import ( | |
| "fmt" | |
| "log" | |
| "net/url" | |
| "os/exec" | |
| "time" | |
| "github.com/zserge/lorca" | |
| ) | |
| func main() { | |
| ui, err := lorca.New("", "", 480, 320) | |
| if execErr, ok := err.(*exec.Error); ok { | |
| lorca.PromptDownload() | |
| log.Fatalf("\nChrome could not be started. Do you have Chrome installed? %s\n", execErr) | |
| } else if err != nil { | |
| log.Fatalf("\nOps. Something went wrong while starting the application: %s", err) | |
| } | |
| defer ui.Close() | |
| ui.Load("data:text/html," + url.PathEscape(` | |
| <html> | |
| <head><title>Calling Go from Js and Js from Go</title></head> | |
| <body> | |
| <h1>1 - Calling Go code from page's Javascript</h1> | |
| <script> | |
| function incrementFromGoCode(button) { | |
| // add() exists in Js because we called ui.Bind("add", func(){}) in Go | |
| add(parseInt(button.value), 1).then(function(valueFromGo){ | |
| button.value = valueFromGo; | |
| }); | |
| } | |
| </script> | |
| Click to call Go: <input type="button" id="button1" value="0" onclick="incrementFromGoCode(this)"> | |
| <h1>2 - Calling Javascript from Go</h1> | |
| <p>Value updated from Go: <span id="span1">0</span></p> | |
| </body> | |
| </html>`)) | |
| // Allows Js to call our Go function add() | |
| ui.Bind("add", func(a, b int) int { return a + b }) | |
| // Calls Js to increment value in HTML every second | |
| go func() { | |
| for i := 0; ; i++ { | |
| ui.Eval(fmt.Sprintf("document.getElementById('span1').innerHTML = %d;", i)) | |
| time.Sleep(1 * time.Second) | |
| } | |
| }() | |
| <-ui.Done() | |
| } |
How would one exit the app via a button, can't seem to find any examples and if you kill the go process the window doesn't die with it.
