Node Sketch Bridge

This package exposes the macOS APIs needed for generating Sketch files. It relies on a node native module written in Obj-C.

npm install --save node-sketch-bridge

API

findFontName

const { findFontName } = require("node-sketch-bridge");

const fontName = findFontName({
  fontFamily: "Helvetica",
  fontStyle: "italic"
});

console.log(fontName); // "Helvetica-Oblique"

createStringMeasurer

const { createStringMeasurer } = require("node-sketch-bridge");

const size = createStringMeasurer(
  [
    {
      content: "Hello",
      textStyles: {
        fontFamily: "Helvetica",
        fontSize: 16,
        fontWeight: "bold",
        fontStyle: "italic",
        lineHeight: 23,
        letterSpacing: 1,
        textDecoration: "underline",
        textAlign: "left"
      }
    }
  ],
  400
);

console.log(size); // "{ width: ..., height: ... }"

makeImageDataFromURL

const { makeImageDataFromURL } = require("node-sketch-bridge");

const base64EncodedImage = makeImageDataFromURL("https://placekitten.com/200/300");

// The buffer will contain the PNG-encoded image of a kitten. Meow.
const imageBuffer = Buffer.from(base64EncodedImage, "base64");

Development

First, run npm install.

To develop in Xcode, you'll need to generate an Xcode project. The following worked for me on Mojave:

npm install --global node-gyp

node-gyp --python /usr/local/bin/python2 configure -- -f xcode

node-gyp build

Then, open build/binding.xcodeproj.
