`module.exports =` and ES6 Module Interop in Node.js

The question: how can we use ES6 modules in Node.js, where modules-as-functions is very common? That is, given a future in which V8 supports ES6 modules:

How can authors of function-modules convert to ES6 export syntax, without breaking consumers that do require("function-module")()?
How can consumers of function-modules use ES6 import syntax, while not demanding that the module author rewrites his code to ES6 export?

@wycats showed me a solution. It involves hooking into the loader API to do some rewriting, and using a distinguished name for the single export.

This is me eating crow for lots of false statements I've made all over Twitter today. Here it goes.

Promises vs Eventual Values

A few times on Twitter, I've complained that Promises are a poor conceptual stand-in for Eventual Values.

A colleague of mine pointed out that I tweet this or something like it every few months. He's correct, I do.

The responses usually flow in saying something to the effect of "Well,

First install Brew on your MAC

Setup Brew: ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
brew update
brew tap homebrew/dupes
brew tap homebrew/php
Install PHP 7.0.+ brew install php70
Install mcrypt: brew install mcrypt php70-mcrypt
Finally, install composer: brew install composer

We want to upload file to a server with POST HTTP request. We will use curl functions.


// data fields for POST request
$fields = array("f1"=>"value1", "another_field2"=>"anothervalue");

// files to upload
$filenames = array("/tmp/1.jpg", "/tmp/2.png");;
