Node.js Stream on Typescript: supplied parameters do not match any signature of call target

In typescript I was trying to implement custom transform stream. But it was giving me typescript error supplied parameters do not match any signature of call target when I call super contructor with options.

var Transform = require('stream').Transform
export class Test extends Transform {
  constructor(options) {
        super(options);
    }
}

Any help will be appreciated. Thanks in advance !!

Because TypeScript does not know the type of the constructor of Transform when you are resolving it using require. You can use the import syntax to import Transform:

import { Transform, TransformOptions } from "stream";

export class Test extends Transform {
    constructor(options: TransformOptions) {
        super(options);
    }
}

Make sure you have the typings for node installed:

npm install --save-dev @types/node
