JavaScriptKit

Swift framework to interact with JavaScript through WebAssembly.

Quick Start

Check out the Hello World tutorial for a step-by-step guide to getting started.

Overview

JavaScriptKit provides a seamless way to interact with JavaScript from Swift code when compiled to WebAssembly. It allows Swift developers to:

Access JavaScript objects and functions
Create closures that can be called from JavaScript
Convert between Swift and JavaScript data types
Use JavaScript promises with Swift's async/await
Work with multi-threading

import JavaScriptKit

// Access global JavaScript objects
let document = JSObject.global.document

// Create and manipulate DOM elements
var div = document.createElement("div")
div.innerText = "Hello from Swift!"
_ = document.body.appendChild(div)

// Handle events with Swift closures
var button = document.createElement("button")
button.innerText = "Click me"
button.onclick = .object(JSClosure { _ in
    JSObject.global.alert!("Button clicked!")
    return .undefined
})
_ = document.body.appendChild(button)
