Effective transpiling of ES6

After publishing my article on ECMAScript 6, some have reached out to ask how I exactly I make it all work.

I refrained from including these details on the original post because they're subject to immiment obsoletion. These tools are changing and evolving quickly, and some of these instructions are likely to become outdated in the coming months or even weeks.

The main tool

When evaluating the available transpilers, I decided to use 6to5, which has recently been renamed to Babel. I chose it based on:

Siedrix

var WebSocket = require('ws');
var userPublicToken = 'apikey';
var username = 'username';

var ws = new WebSocket('wss://stream.tutum.co/v1/events?token='+ userPublicToken +'&user=' +username);

ws.on('open', function() {
    console.log('Connected');
});

jparreira

var https = require('https');

exports.handler = function(event, context) {
    var appkey = 'YOUR_REALTIME_APPKEY';
    var privatekey = 'YOUR_REALTIME_PRIVATEKEY';
    var channel = 'aws-iot';
    var message = JSON.stringify(event);
    var postBody = "AK=" + appkey + "&PK=" + privatekey + "&C=" + channel + "&M=" + message;
    
    var headers = {

Juttle API Proxy

This is a simple proof-of-concept example of how one could embed Juttle-powered charts and visualizations in a custom application.

Installing / Running

Requires node.js to be installed.

1) go to https://ropsten.etherscan.io/verifyContract?a=0xa32b21ba14fd476757e392db5d1bbc833eaedaf5
2) enter contract address, name, compiler
3) copy code of contract flatten out (delete import and replace by actual code)
4) truffle console
5) var Eth = require('ethjs')
6) Eth.abi.encodeParams(["uint256", "uint256", "uint256", "address", "uint256"], ["1508105298", "1508710098", "200", "0x3d208fabaf7e919985d5d2f068f28d6a9022e8d5", "5000000000000000000000000000"])
7) copy paste result of encodeParams without '0x'
