js_bindings 0.1.2

Complete JS bindings interop with autocomplete and documentation.

This is (or should be) a full JavaScript interop package using package:js bindings.

The bindings are generated by machine-reading WebIDL files for types and MDN website for documentation.

Take a look at MediaStream file and check out how nice it got with the awesome MDN documentation.

Usage

import 'package:js_bindings/js_bindings.dart';

void main() {
  var div = document.createElement('div')
    ..innerHTML = 'Hello world =]';
  
  document.body!.appendChild(div);
}

Check the example tab for a more complete example.

Promise and Future

JS Promises and Dart Futures are different things.
But this package make them the same! :D

import 'package:js_bindings/js_bindings.dart';

Future<void> main() async {
  // you can await like regular future
  await window.navigator.mediaDevices.getUserMedia();
  // or 
  window.navigator.mediaDevices.getUserMedia().then((event) {});
}

Enums

Enums like document.visibilityState are Strings in JS world, but here we work with enums instead. For example document.visibilityState is of type VisibilityState, which is a Enum.
So all of what is specificied in the W3C IDL files as enums are in fact enums in this package.

Variadic args

Dart doesn't have the concept of variadic args as JS, so we can't make a one to one there. However, we made it that variadic arguments are multiplied to 3 optional args of same type.
Example: window.console.log(1, 2, 3) - In this case all arguments are dynamic.

Todo:

• Generate stream for events
• Create a builder for JS builtin stuff
