A modern programming language that makes developers happier.

kotlinlang

For testing purposes, I’m adding the ability to read `*.json` files into kotlin strings. My project targets JVM, JS, and iOS. 

My approach was to create a common:

```
expect fun readFileToString(file: String) : String?
```
 
And then implement actuals in each target.

I have iOS and JVM working, but am not sure of the best way to implement the `actual` in JS. 

Here’s my JVM `actual`:


```
import java.io.File

actual fun readFileToString(file: String) : String? {
    return File(file).readText(Charsets.UTF_8)
}
```

Anyone done something like this? 

I assume I’ll use `fs.fileReadSync:` but I’m not sure what I need to import to access that method?

You can convert a Promise into a suspending function:
```
suspend fun &lt;T&gt; Promise&lt;T&gt;.await(): T = suspendCoroutine { cont -&gt; 
    then({ cont.resume(it) }, { cont.resumeWithException(it) })                                                      
}
```
Then if there exists a thing in node that isn't in the stdlib for kotlin you can write a definition for it with `external fun`.
