Webpack compatibility

[derdrdirk]

I am using Webpack to bundle my code for the later export to my server-less architecture. Unfortunately Google-Cloud does not seem to work with the Webpack workflow? Executing the from webpack produced bundle yields the error:

throw new Error("package.json does not exist at " + package_json_path);

Do to my research this is a problem with some Google Cloud dependencies:
googleapis/google-cloud-node#1821
grpc/grpc#11435

and the source probably is the node-pre-gyp module:
mapbox/node-pre-gyp#308

Environment details

• OS: MacOS 10.13.2
• Node.js version: v9.3.0
• npm version: 5.6.0
• dialogflow version: v2

Thanks!

Greetings! Webpack isn't currently supported, but it's something we would very much like to do.

This workaround helps serverless-heaven/serverless-webpack#342

[sibelius]

can we use this package on react-native?

right now we are using fetch directly like this https://github.com/innFactory/react-native-dialogflow/blob/master/js/Dialogflow_V2.js#L89

it'd be cool to have full support to react and react native

I got the same issue to use @google-cloud/pubsub.
So I use the cloud Pubsub REST API directly.
Why don't you do this?

// example
import { google } from "googleapis";
import axios from "axios";
const url = "https://pubsub.googleapis.com/v1/projects/${project_name}/topics/${topic_name}:publish";

async function main() {
  const token = await google.auth.getAccessToken();
  const data = { messages: [ { data: new Buffer("hogehoge").toString("base64") }]}
  const config = {
    headers: {
      "Content-Type": "application/json",
      Authorization: `Bearer ${token}`,
    },
  };
  return await axios.post(url, data, config);
}

main();

Is there any work around or fix available to use dialogflow in reactjs?

[bcoe]

@ragu-swaminathan, we recently removed our dependency on grpc (which was a compiled dependency, and made running in reactjs a complete no-go); however, there's still some work to go before this library can easily be run in the browser.

This continues to be something we are working towards, but I don't believe there are any workarounds just yet.

@bcoe @JustinBeckwith is there a tracking issue we can ask users to subscribe to? Seems like this is applicable to all the nodejs clients.

[bcoe]

@callmehiphop if one doesn't exist, let's create a tracking issue here:

https://github.com/googleapis/google-cloud-node

I agree it would be great to eventually provide a recipe for running in the browser.
