### 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())
```
