Add support for angular

Error message

ERROR in ./node_modules/google-gax/build/src/operationsClient.js
Module not found: Error: Can't resolve './operations_client_config' in 'C:\Users\chenxi.zhao\workspace\chatbot-designer\node_modules\google-gax\build\src'
ERROR in ./node_modules/google-auth-library/build/src/auth/googleauth.js
Module not found: Error: Can't resolve 'child_process' in 'C:\Users\chenxi.zhao\workspace\chatbot-designer\node_modules\google-auth-library\build\src\auth'

Environment details

• OS: WIN 10
• Node.js version: 10.16.0
• npm version: 6.9.0
• dialogflow version:0.10.2

Steps to reproduce

I am very sure the library google-gax and google-auth-library is correct installed.
But I got error as above.
Basically, this is angular8 + universal project.
when I build project with npm run build:ssr, it says the modules not found.
I google a lot, it says google library compact with webpack? I tried everything, but nothing works.

import {Observable} from "rxjs";

import { Intent } from 'src/app/models/intent';

const dialogflow = require('dialogflow');

@Injectable({
providedIn: 'root'
})
export class IntentService {
.......
.......
readonly intentsClient = new dialogflow.IntentsClient(this.opts);
readonly request = {
    parent: this.projectAgentPath,
    intentView: 'INTENT_VIEW_FULL',
};

constructor() { }

fetchIntents(): Observable<Intent[]> {
  return this.intentsClient.listIntents(this.request);
}
}

Making sure to follow these steps will guarantee the quickest resolution possible.

Thanks!

👋 hello @ceciliazcx, currently nodejs-dialogflow does not work in a frontend context, as it relies on libraries that exist in Node.js but not the browser, e.g., http2, child_process.

there are efforts in the works to make libraries like dialogflow work for the frontend, but we're not quite there yet.

@bcoe ok. Thx for reply. I basically only want to get intents from dialog flow. Is there any other I can do it from angular?

Could you give this library a try?
https://github.com/googleapis/google-api-nodejs-client/

It's less easy to work with, but is known to be webpack-able.

Hey guys, is angular still not supported? I am trying to add dialog flow to my ionic angular project and got the same error.
