Binding Async Java Functions to JavaScript

[webfolderio]

Hi,

I am trying to bind a Java method to JavaScript but couldn't figure out how to use it with Promise.
I check the documentation and promise test class but still couldn't find the solution.

Thanks

Example usage:

Java:

class Service {
 public String longRunningTask() {
  return "done";
 }
}

JavaScript:

var myFunc = async function() {
  var service = new Service();
  await service.longRunningTask();
};

Note: I am using pure v8 without node support.

Nice catch. That piece of work hasn't been fully implemented, as I'm adding the Proxy based injection now. Promise is a wonderful feature that requires certain amount of work. You are welcome to discord (link is at home page), discussing that with me in detail.

The gap is being closed now. Please check this commit out for detail and let me know if you have any questions.

Please check out the source code of Javenode that has many practical usage of Promise for async operations.
