angular 2 在打字稿中使用 javascript 包

Question

I'm trying to use SignalR in an Ionic/Angular 2 application.

I'm building a simple Hub like so:

const accessToken = authManager.getRawAccessToken();

let hubUrl = environment.baseUrl + 'messages';
if (accessToken) {
    hubUrl += '?authToken=' + accessToken;
}

this._hubConnection = new HubConnectionBuilder()
                           .withUrl(hubUrl)
                           .build();

I keep getting an error:

Cannot find name 'XMLHttpRequestResponseType'.

because SignalR requires a higher version of typescript than what's support currently by Ionic. https://github.com/aspnet/SignalR/issues/1375

I noticed SignalR is shipped by default using Javascript. Is there a way I can change my Import statement

import { HubConnection, HubConnectionBuilder } from '@aspnet/signalr';

So I can import javascript into a Typescript file as Any?

Edit I've also tried:

import * as SignalR from '@aspnet/signalr';

but this still seems to use the typings file.

Answer 1

To use Js instead of Typescript?

Use raw require :

const { HubConnection, HubConnectionBuilder } =  require('@aspnet/signalr');

The types for require are provided by npm i @types/node 🌹
