Quick and dirty "docker pull"-like shell script.

Higher-level classes for synchronizing a nested Firebase ref, FirebaseEventEmitter and FirebaseImmutable. Work in progress.
Firebase = require "firebase"
Immutable = require "immutable"
{ EventEmitter } = require "events"
# Recursively listens to Firebase ref for modifications and emits "add",
# "change", and "remove" events with a path and value (except for "remove")
class FirebaseEventEmitter extends EventEmitter
constructor: (url) ->
EventEmitter.call(@)

Super simple git post-receive hook for Node.js + nvm + npm + node-foreman + init (Ubuntu) deployment

Last active January 7, 2022 03:14 — forked from eoinkelly/visualize-stacking-contexts.js
Some console output to help you visualise stacking contexts on a page (no jquery)
/*
Usage:
* Paste this into your dev tools console (or even better as a snippet)
* It will parse the page and find all the things that create a new stacking context
and dump some info about them to the console. It will also outline them on the page.
* This is pretty rough and probably misses heaps of bugs and edge cases.

Steps for merging an old branch into a newly prettier-ified codebase. Use at your own risk, verify everything was correctly merged.
# Assumes 3 sequential commits:
#
# 1. commit tagged "prettier-before" that added `prettier` depedency and `prettier` script your package.json
# 2. commit that actually ran `prettier` on your entire codebase for the first time
# 3. commit tagged "prettier-after" that fixes any minor issues caused by prettier (e.x. moving eslint-ignore or $FlowFixMe comments around), or just the next commit if there were none
#
# I recommend running these as individual commands, not as a script, in case of merge conflicts
#
# Checkout the non-pretty branch you want to merge
# (or optionally make a new branch with `git checkout -b $YOUR_BRANCH-prettier $YOUR_BRANCH`)
