# node-native-extension-in-swift

　　　

An experimental repo for [Node.js native addons](https://nodejs.org/api/addons.html) that written in Swift.  

The first motivation of implementeing this was reduceing overhead of execution between Node.js and Swift on the Serverless environment.

## Writing native extensions with Swift

1. Define function(s) in a format that can be exported to C/C++ in Swift side.

```swift

@_cdecl("swift_fibonacci") // Name the function symbol.

public func fibonacci(_ n: CInt) -> CInt {

    if n == 0 {

        return 0

    } else if n == 1{

        return 1

    }

    return fibonacci(n - 1) + fibonacci(n - 2)

}

```

2. [Register fibonacci as callable function in Node.js (V8 side)](https://github.com/noppoMan/node-native-extension-in-swift/blob/master/swift.cc#L53)

3. The exported functions can be imported and executed in Node.js side.

```js

const swift = require('bindings')('swift');

const result = swift.fibonacci(10);

console.log(result);

```

## Running Example

## Linux

```sh

$ docker build -t node-native-extension-in-swift .

$ docker run -t node-native-extension-in-swift

```
