CandyJS：架起Golang和JavaScript透明之桥

jopen 10年前

CandyJS是意图创造一座Go语言和JavaScript引擎duktape之间完全透明的桥，通过使用反射技术在go-duktape之上建立一个语法糖库，允许用户执行任意代码（即插件）不需要编译它就可建立可扩展的应用程序。

Features

Embeddable Ecmascript E5/E5.1 compliant engine (duktape). 

ctx := candyjs.NewContext()  ctx.EvalString(`    function factorial(n) {      if (n === 0) return 1;          return n * factorial(n - 1);    }      print(factorial(10));  `)  //3628800

Call Go functions from JavaScript and vice versa. 
ctx := candyjs.NewContext()  ctx.PushGlobalGoFunction("golangMultiply", func(a, b int) int {      return a * b  })    ctx.EvalString(`print(golangMultiply(5, 10));`) //50

Transparent interface between Go structs and JavaScript. 
type MyStruct struct {      Number int  }    func (m *MyStruct) Multiply(x int) int {      return m.Number * x  }  ...  ctx := candyjs.NewContext()  ctx.PushGlobalStruct("golangStruct", &MyStruct{10})    ctx.EvalString(`print(golangStruct.number);`) //10  ctx.EvalString(`print(golangStruct.multiply(5));`) //50
