Support shell entry?

Is there any way to execute node as if it were on the command line

like

goja main.js

No, this feature is not available in goja_nodejs at the moment. But it is possible to do it. goja_nodejs is a module and can therefore be used by other programs written in Golang. You can use goja_nodejs in a project and build the project like this:

The Go code goja_nodejs.go:

package main

import (
    "os"
    
    "github.com/dop251/goja"
    "github.com/dop251/goja_nodejs/console"
    "github.com/dop251/goja_nodejs/require"
)

func main() {
    registry := new(require.Registry)
	
    runtime := goja.New()
    registry.Enable(runtime)
    console.Enable(runtime)
    registry.Enable(runtime)

    filePath := os.Args[1] // Take the js file from the process arguments list
    file, err := os.ReadFile(filePath) // Resolve the js file
    if err != nil {
        panic(err)
    }

    runtime.RunString(string(file)) // Pass the js file content to goja
} 

The Javascript code main.js:

console.log("Hello world");

Then build the project:

go build goja_nodejs.go

After that run the exectutable:

./goja_nodejs /home/dev/goja_nodejs_exec/main.js

See the result of execution in the console:

Hello world

You can also run without compiling:

go run goja_nodejs.go /home/dev/goja_nodejs_exec/main.js

It should be noted that because this is for a demonstration the path to the js file must be absolute.
