Sketch plugin development cheat sheet

sketchCheats.js

// NEW API
const sketch = require('sketch');
const document = sketch.getSelectedDocument();
const selection = document.selectedLayers;
const layerSelected = selection.layers[0];
const style = layerSelected.style;
const borders = style.borders;

// OLD API
const doc = context.document;
const page = doc.currentPage();
const selection = context.selection;
const style = selection[0].style();

// sharedDoc
NSDocumentController.sharedDocumentController().currentDocument();

// Example
var sketch = require('sketch')
var document = sketch.getSelectedDocument()
var selectedLayers = document.selectedLayers
var selectedCount = selectedLayers.length

if (selectedCount === 0) {
  console.log('No layers are selected.')
} else {
  console.log('Selected layers:');
  selectedLayers.forEach(function (layer, i) {
    console.log((i + 1) + '. ' + layer.name)
  })
}
