This example uses the Sketch JavaScript API to add a fixed-size green view overlay onto the canvas of the currently selected document. The code retrieves the canvas placeholder view and its first subview, then creates an NSView with a green background and adds it as a subview. Layout constraints—using NSLayoutConstraint and relatedBy methods—anchor the overlay to the top-left corner and enforce fixed width and height values of 40 and 100 points, respectively.

Creating a Sketch NSPanel

This example demonstrates how to create a custom, frameless floating panel with a vibrant, translucent background using the Sketch JavaScript API. The script creates an `NSPanel` with a titled, closable, and resizable window, and applies a `NSVisualEffectView` with a vibrant light appearance to achieve a frosted-glass effect. It uses `NSLayoutConstraint` objects to anchor the visual effect to the panel’s content view. The panel’s close button is handled via `setCOSJSTargetFunction`, which cleans up the panel reference and stops the script’s keep-alive loop.

Add a Color layer on top

A Sketch plugin script adds a full-artboard color overlay to visually inspect design contrast. It targets either a selected artboard or a layer within one, then creates a locked `ShapePath` named "Greyscale Layer" with a white fill and `Style.BlendingMode.Color`. The script uses `sketch` APIs like `getSelectedDocument`, `Rectangle`, and `ShapePath` to construct the overlay. If a greyscale layer already exists on the artboard, the script removes it before adding a fresh one.

This example demonstrates how to construct and arrange basic geometric shapes within a Sketch document using the `sketch` JavaScript API. The code programmatically creates an artboard and populates it with a square, a triangle, a hexagon, and a circle, each styled with distinct fill colors or a bordered outline. The `ShapePath` class and its `ShapeType` enumerations are the core components, with coordinates and dimensions set through `frame` objects. The rendering approach is code-driven, defining visual elements directly without external data sources, showcasing the library’s programmatic drawing capabilities.

Basic Window Loading a URL

This example demonstrates a Sketch plugin that opens a floating panel and loads a remote SVG image from the Sketch website into a web view. The plugin uses AppKit’s `NSPanel` to create a borderless, floating window with hidden minimize and zoom buttons. It initializes a `WKWebView` from the WebKit framework, configures it with developer extras enabled, and loads the specified URL via `NSURLRequest`. The panel is centered and kept on top using `NSFloatingWindowLevel`.

This example demonstrates a Sketch plugin that launches a floating panel window with a table view interface. The code uses Sketch’s JavaScript API, `NSThread`, `NSPanel`, and `NSMakeRect` to construct a 312×210 pixel textured window, position it at the screen center, and set it to float above other windows. It manages a thread dictionary key to prevent duplicate panels, toggling the window open or closed on repeated plugin runs. The plugin calls `document.showMessage()` for user feedback and hides the miniaturize and zoom buttons via `standardWindowButton`, with the table view setup currently stubbed out.

Making cool lines in Sketch

A generative drawing built with the Sketch JavaScript API draws a symmetric, web-like pattern of red lines on a black artboard. The example shows how four nested loops create a series of straight ShapePath segments, each with semi-transparent red borders, that collectively form a repeating geometric motif. It demonstrates programmatic layer creation, setting frame and style properties, and using the `adjustToFit` method to size the group. The code uses `sketch.getSelectedDocument`, `Artboard`, `Group`, and `ShapePath` to generate the composition directly within Sketch's document model.

TableView start

This Sketch plugin example demonstrates a floating panel containing a table view with a custom data source. The panel is built using native Sketch APIs like `NSPanel`, `NSScrollView`, and `NSTableView`, and it populates the table through a dynamic delegate created with `MochaJSDelegate`, which intercepts selector-based callbacks to supply row and column values. The code sets up a single-column grid with alternating row colors, red grid lines, and a fixed height, and logs data requests to the console.

Add padding to artboard (WIP)

This plugin demonstrates how to adjust an artboard's dimensions and reposition its contents with a user-defined padding value. It uses the Sketch JavaScript API, including `doc.selectedLayers`, `Rectangle`, and `UI.getInputFromUser`, to prompt for input and modify layer frames. The script shifts the artboard’s frame outward by the padding amount while moving all nested layers inward by the same value, preserving their relative positions. It relies on `selection.frame` and `layer.frame` properties to apply geometric transformations.
