Amplify-js: Error while building: Cannot find type definition file for 'paho-mqtt'.
Do you want to request a feature or report a bug? bug
What is the current behavior?
When I build my project I get this error in console:
[13:15:45] typescript: node_modules/aws-amplify/lib/PubSub/Providers/MqttOverWSProvider.d.ts, line: 1
Cannot find type definition file for 'paho-mqtt'.
L1: import { Client } from 'paho-mqtt';
L2: import * as Observable from 'zen-observable';
Which versions of Amplify, and which browser / OS are affected by this issue? Did this work in previous versions?
aws-amplify 0.2.14

Hey @ildar-icoosoft could you run npm install @types/paho-mqtt?

@richardzcode Why does aws-amplify has not paho-mqtt dependency in package.json? I don't want to know about all your dependencies. This is a bug and you should not close this issue. Also I see nothing about npm install @types/paho-mqtt in your documentation

Followed the documentation and looked at nothing else, had the same issue on building an Angular application from scratch. Thankfully someone had a similar issue.

@ildar-icoosoft thanks for the feedback, agreed, this should be added we will add this into the next release.

@Jasminou I created a new app through Angular CLI (CLI version 1.7.4 and Node at version 9.11.1 if that matters).
ng new <app-name>
After that, the only package I installed was aws-amplify.
npm install --save aws-amplify
Now, if you start using amplify (I only used Auth as a test) and building your application using ng serve, you'd notice a ton of errors pop up.

To fix the missing type definition files:
npm install --save-dev @types/paho-mqtt this will fix only the first error,
npm install --save-dev @types/zen-observable should fix the zen-observable missing type definition
The remaining errors are due to missing typings on the aws-sdk package. You can view a fix for that here: https://github.com/aws/aws-sdk-js/issues/1271
Based on the discussion on that link:
Install node typings npm install --save-dev @types/node and then adding "types": ["node"] to the tsconfig.app.json inside the src folder generated by the Angular CLI. This should fix the last remaining errors.
I don't know if there are other errors though as I only used the Auth module as a test.
