How do I use RequestPromise in TypeScript?

Question

I have installed request-promise library and trying to use it in my TypeScript app but without much luck.

If I use it like this:

import {RequestPromise} from'request-promise';

RequestPromise('http://www.google.com')
        .then(function (htmlString) {
            // Process html...
        })
        .catch(function (err) {
            // Crawling failed...
        });

I see this on TS compile output:

error TS2304: Cannot find name 'RequestPromise'.

If I use it this way:

import * as rp from'request-promise';

rp('http://www.google.com')
    .then(function (htmlString) {
        // Process html...
    })
    .catch(function (err) {
        // Crawling failed...
    });

I see an error that says that there is no '.then()' method on object rp.

How do I properly use it with TypeScript?

You must import all (*) not just RequestPromise:

import * as request from "request-promise";
request.get(...);

This answer elaborates on the differences between import/from and require.
