Cannot find module './lib/BufferMaker' when use buffermaker in Meteor 1.5.1 - node.js

Question

I have encountered a problem when use some npm package in Meteor (version 1.5.1), any help on it will be much appreciated.
My Environment:
meteor: 1.5.1
buffermaker: 1.2.0
What I Did:
Create a sample Meteor app.
meteor create test
Install buffermaker
meteor npm install --save buffermaker
Import buffermaker in Meteor app by editing test/client/main.js, add line:
import { BufferMaker } from 'buffermaker';
Full content of test/client/main.js:
import { Template } from 'meteor/templating';
import { ReactiveVar } from 'meteor/reactive-var';
import { BufferMaker } from 'buffermaker';
import './main.html';
Template.hello.onCreated(function helloOnCreated() {
// counter starts at 0
this.counter = new ReactiveVar(0);
});
Template.hello.helpers({
counter() {
return Template.instance().counter.get();
},
});
Template.hello.events({
'click button'(event, instance) {
// increment the counter when button is clicked
instance.counter.set(instance.counter.get() + 1);
},
});
Run the Meteor app
meteor npm install
meteor
I got this error in the console of browser (Chrome).

Answer 1

Did you try:
import BufferMaker from 'buffermaker';
Some if not most modules do a default export meaning that you don't need the curley braces in your import statement

Answer 2

Turns out buffermaker re-exports it’s main module in a strange way, so first step is to bypass it by importing BufferMaker directly:
import BufferMaker from 'buffermaker/lib/BufferMaker';
Then you’ll find when you call .make(), it will complain about Buffer not existing. To get Buffer on the client, first install meteor-node-stubs
$ meteor npm install --save meteor-node-stubs
Then load the buffer module and stick it on the window so BufferMaker can access it
import { Buffer } from 'buffer';
window.Buffer = Buffer;
/* OR do it with require */
window.Buffer = require('buffer').Buffer;
