Reading/writing a sketch file without opening it

read.js

let sketch = require('sketch')
let Document = sketch.Document
let path = "/Users/kgutowski/Downloads/Test.sketch"
let url = NSURL.fileURLWithPath(path)
let externalDoc = MSDocument.alloc().init()
externalDoc.readDocumentFromURL_ofType_error(url, "com.bohemiancoding.sketch.drawing", nil); // Be sure to capture error properly
let jsDoc = Document.fromNative(externalDoc)
console.log(jsDoc)

write.js

let doc = MSDocument.alloc().init()
let url = NSURL.URLWithString('/Users/Kski/Downloads/mysketchfile.sketch')
doc.writeToURL_ofType_options_error(url,"com.bohemiancoding.sketch.drawing",nil,nil)

Hi Kevin.

I came to your github while searching Swift codes.

You are using "NSURL" in javascript.

How do you access object.c or swift object in Javascript ?

I'm writing app using node.js, I want to call some swift function in node.js

You can’t call swift functions with only node.js. You will need to have your app compiled for MacOS and to have node bundled in it, and then use something like Cocoascript to bridge your JS commands to objective-c. I recommend if you want to write Swift then switch over to writing a Mac app.
