App engine hello world example too many dependencies

[randomekek]

Hello, the hello app engine hello world seems to depend on express. Please remove the dependency, as hello world should always be as succinct as possible for pedagogical purposes!

Is google-cloud/nodejs-repo-tools even strictly necessary?

const http = require('http');
const PORT = process.env.PORT || 8080;

const server = http.createServer((request, response) => {
  console.log(request.url);
  response.end('Hello Node.js Server!');
});

server.listen(PORT, err => {
  console.log(`App listening on port ${PORT}`);
  console.log('Press Ctrl+C to quit.');
});

I agree, npm install takes a long time considering this is just hello-world.

We use @google-cloud/nodejs-repo-tools for the tests. We're in the process of simplifying this.

Also points to deprecated npm install -g @google-cloud/functions-emulator
and doesn't inform you how to set the project: ie

➜  helloworld git:(master) gcloud functions deploy helloGET --runtime nodejs8 --trigger-http

ERROR: (gcloud.functions.deploy) Error parsing [name].
The [function] resource is not properly specified.
Failed to find attribute [project]. The attribute can be set in the following ways:
- provide the argument [--project] on the command line
- set the property [core/project]
➜  helloworld git:(master)

But thanks for these examples, glad I don't have to depend on Serverless framework now, just another layer than can go wrong.

@ace-n, can you look at the @google-cloud/functions-emulator dependency? Is that effort tracked somewhere?

[ace-n]

This is more-or-less tracked in #1333. (Right now, this is blocked on fully updating the functions tests per [Google internal] b/134942934. Once that's done, it would probably only take 1-2 reasonable-sized PRs.)

This is also vaguely on my radar. My task queue is currently 100% full however, so it'll likely be at least a few weeks before I have time to look at this. (You're welcome to beat me to it, of course.)

I'm working on removing nodejs-repo-tools for testing hello-world
