Sketch.app
You can integrate Sketch into your app or worflow using the sketch:// URL scheme. You can even open documents in Sketch already focused on specific layers or with a specified zoom level.
Note: If a document is already open the canvas view does not change.
Center layer and specify zoom level
The URL scheme accepts two parameters. If the path to the file is provided without any parameters the file will be opened in the same way it was last saved.
sketch://path/to/file.sketch?centerOnLayer=LAYER_ID&zoom=ZOOM_LEVEL
centerOnLayer string
To obtain the layer id use either the JavaScript API or read the document’s JSON data directly.
Example
To get the id of the current selection, select a layer within the current document in Sketch and run the following script from the Run Script… panel in the Plugins menu.
const document = require('sketch/dom').getSelectedDocument()
document.selectedLayers.forEach(layer => console.log(layer.id))
zoom number
Actual Size has a zoom level of 1. To zoom out specify values between 0...1 while using values greater than 1 to zoom in, e.g. 2 for 200%.
