PR #430 Breaks Stream interface in Node.js

[Artmobile]

PR #430 breaks fluent interface nature of Node.js Stream:

To reproduce, uncomment require("zone.js"). The code will crash because createInterface and on do not return self which prevents cascading

//require("zone.js")
const fs = require("fs")

require('readline').createInterface({
  input: fs.createReadStream('/etc/hosts')
}).on('line', function (line) {
  console.log(line)
}).on('close', function () {
  console.log('done')
});

createInterface works correctly as it's not patched by Zone, on is fixed in the PR.

Is the pull request going to be merged soon? #475

For others finding this issue, you might have luck with the following workaround, provided you are not using the event integration in node.js

require('zone.js');
var events = require('events');
events.prototype.on = events.prototype.__zone_symbol__addListener;
events.prototype.addListener = events.prototype.__zone_symbol__addListener;

I use it myself for now but would really love to get rid of it since, it does disable the integration in the event system.

As a bit of background info, I have this dependency in order for getting angular2 dependency injection to work in my server side typescript.
