Was playing around with Ts and got stuck at this
"use strict";
declare const require: any;
const EventEmitter : any = require('events').EventEmitter;
class Foo extends EventEmitter{ //*error* Type 'any' is not a constructor function type.
constructor() {
super();
}
}
I also tried to assign EventEmitter to an interface type of mine, which gave the same error.
How can I extend a class, with commonjs modules using Typescript?
Thank you
try
"use strict";
import { EventEmitter } from 'events';
class Foo extends EventEmitter {
constructor() {
super();
}
}
You may need to install type definition for 'events' module:
npm install --save @types/node
Update
You can still do the same with require:
"use strict";
import events = require('events');
const EventEmitter = events.EventEmitter;
class Foo extends EventEmitter {
constructor() {
super();
}
}
You should avoid using : any in general so you can use features like IntelliSense and compile-time type checking
require solution also be possible using something like node.d.ts , like mentioned here stackoverflow.com/questions/18378503/…
