Summarizes repo language stats for top 100 (by star count) user owned repos to get a "feel" for user language preference/experience. Replace GITHUB_USERNAME with a user you want to summarize and YOUR_GITHUB_API_TOKEN with the access token (https://help.github.com/articles/creating-a-personal-access-token-for-the-command-line/)
"use strict";
const https = require("https");
const API_TOKEN = "YOUR_GITHUB_API_TOKEN";
const GITHUB_USER = "GITHUB_USERNAME";
const request = (options, postBody) => {
return new Promise((resolve, reject) => {
const req = https.request(options, res => {
let body = "";

Demonstrates how a file can be read as a stream (from network), piped through gzip and into an s3 bucket without having to store it locally our load it whole in memory
const { Writable, Readable, PassThrough } = require("stream");
const { inherits } = require("util");
const AWS = require("aws-sdk");
const zlib = require("zlib");
const https = require("https");
const gzip = zlib.createGzip();
const s3 = new AWS.S3();
// Change the bucket name to point to an S3 bucket write-able within the IAM role assigned to your Lambda
