How to use Closure imports with normal node.js apps?

https://developers.google.com/closure/library

The doc only mentions how to use closure with browser. How to use it with normal node.js apps?

I npm install google-closure-library and google-protobuf. I generated the myproto_libs.js with protoc-gen-js.

How to use the myproto_libs.js with it? I know that I can use commonjs style. And it works. But I'd like to know the closure style usage.

require('google-closure-library');
require('google-protobuf');

goog.require("goog.crypt.Sha1");

var sha1 = new goog.crypt.Sha1();
sha1.update("foobar");
var hash = sha1.digest();
console.log(hash);

goog.require('proto.Test');
let test = proto.Test();
console.log(test);

Can you tell us about your use case? Generally speaking, these are different module systems and I'm not sure if there's a way to get node to understand closure modules.

I want to use it with Angular. I'm not sure what's the preferred way to use with it. I thought that the closure is a google product as well. It maybe better with Angular, protobuf-javascript and Closure.

From asking around and doing a bit of digging online, it seems like the best option is to use google-protobuf with commonjs imports with angular. Our understanding is that most users rely on commonjs for bundling.
