amazon-web-services - NativeScript AWS AppSync集成

我已经学习了多个有关角度Web的AppSync教程，但是尝试在NativeScript中重复该过程更加困难。看起来像people have done it before，所以任何使它起作用的人的输入都会很棒。

按照我对常规角度应用程序所做的相同常规过程，我尝试使用aws-appsync和nativescript-nodeify使其与nativescript兼容。添加nativescript-nodeify摆脱了我的最初错误，但是现在我遇到了一个新错误：

我得到的错误是：

***** Fatal JavaScript exception - application has been terminated. *****

初始化AWSAppSyncConfig时出现错误。相关代码如下：

require('nativescript-nodeify');

const appSyncConfig = ...

import AWSAppSyncClient from 'aws-appsync';
import { AUTH_TYPE } from 'aws-appsync/lib/link/auth-link';

...

const client = new AWSAppSyncClient({
   url: appSyncConfig.aws_appsync_graphqlEndpoint,
   region: appSyncConfig.aws_appsync_region,
   auth: {
      type: AUTH_TYPE.AMAZON_COGNITO_USER_POOLS,
         jwtToken: ACCESS_TOKEN
      }
});

错误消息指向non-terminated-link.js中的这一行：

var linkUtils_1 = require("apollo-link/lib/linkUtils");

最佳答案

该问题最终与打字稿2.9。*和aws-appsync 1.3.4之间的兼容性问题有关。我将打字稿更新为3.0.3，现在可以使用了
