### ECMASwift

ECMASwift intends to implement a tiny subset of Browser APIs (mostly networking related) to make code sharing between iOS/macOS apps and the web easier.

### Features

ECMASwift exposes the following browser APIs to JavascriptCore, some of these are incomplete, contributions welcome.

- Blob

- Console

- Crypto

- Fetch

- FormData

- Headers

- Request

- TextEncoder

- Timers

- URL

- URLSearchParams

### Examples

In Javascript:

```js

// Define an async function to fetch some dummy data in Javascript

async function fetchProducts() {

    try {

        const res = await fetch("https://google.com")

        return await res.json()

    } catch(error) {

        console.log(error)

    }

}

```

In Swift:

```swift

import ECMASwift

import JavaScriptCore

// Initialise the runtime

let runtime = JSRuntime()

// Load the javascript source file defined above, alternatively JS can be written inline.

let javascriptSource = try! String(contentsOfFile: "./example.js")

// Evaluate the script

_ = runtime.context.evaluateScript(javascriptSource)

// Call the `fetchProducts` function defined in the source file.

let result = try! await runtime.context.callAsyncFunction(key: "fetchProducts")

// Print the result

print(result.toString())

```
