Can someone show me how to implement RequestPromise in TypeScript?

I recently integrated the request-promise library into my TypeScript project, but I am facing some challenges in utilizing it effectively.

When attempting to use it in the following manner:

import {RequestPromise} from 'request-promise';

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

I encounter the following error during compilation:

error TS2304: Cannot find name 'RequestPromise'.

Alternatively, if I try using it like this:

import * as rp from 'request-promise';

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

An error is thrown indicating that there is no '.then()' method on the object rp.

Can someone provide guidance on the correct way to implement request-promise with TypeScript?

Answer №1

To properly utilize the functionality, make sure to import everything (not just RequestPromise):

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

This explanation provides more insight on the variances between import/from and require.

Answer №2

Utilize request-promise's TypeScript package

npm install --save-dev @types/request-promise
import { get, put, post } from 'request-promise';

How to Use

get(options).then(body => {

    console.log(body)

}).catch(e => reject);

Answer №3

This is how I implement request-promise:

import * as requestPromise from 'request-promise';

const options = {
    uri: _url,
    proxy: https://example.host.com:0000,
    headers: {
        Authorization: 'Bearer ' + token
    }
};

requestPromise.get(options, (error, response) => {
    if (error) {
        // Handle errors here
    } else {
        if (response.statusCode !== 200) {
             // Handle error responses
        } else {
             // Implement success logic here
        }
    }
});
