Rationale

This snippet is a sample showing how to implement CloudWatch Logs streaming to ElasticSearch using terraform. I wrote this gist because I didn't found a clear, end-to-end example on how to achieve this task. In particular, I understood the resource "aws_lambda_permission" "cloudwatch_allow" part by reading a couple of bug reports plus this stackoverflow post.

The js file is actually the Lambda function automatically created by AWS when creating this pipeline through the web console. I only added a endpoint variable handling so it is configurable from terraform.

# Retrieve branch name
branch=$(git branch --no-color 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/\1/')

# Retrieve destination branch
destination_branch=${branch%--*}

# Determine the default origin branch
if [[ $branch == $destination_branch ]]; then

#!/usr/bin/env bash
# gpr - push the current branch to origin and attempt to open the Create Pull

Profiling in production

React DOM automatically supports profiling in development mode for v16.5+, but since profiling adds some small additional overhead it is opt-in for production mode. This gist explains how to opt-in.

Basics

File descriptors

The bash has three default file descriptors for each process:

// Go to: https://<team>.slack.com/customize/emoji
// Open Developer Console
// Copy/Paste and Run this in the console:

var spans = document.getElementsByTagName('span');
var basharray = "( "
for (var i=0;i<spans.length;i++) {
    var link = spans[i].getAttribute("data-original"); 
    if(link != null){
        basharray = basharray.concat(link, " ")
