maxdevjs

Most configuration really isn't about the app -- it's about where the app runs, what keys it needs to communicate with third party API's, the db password and username, etc... They're just deployment details -- and there are lots of tools to help manage environment variables -- not the least handy being a simple .env file with all your settings. Simply source the appropriate env before you launch the app in the given env (you could make it part of a launch script, for instance).

env files look like this:

SOMEVAR="somevalue"
ANOTHERVAR="anothervalue"

To source it:

$ source dev.env # or staging.env, or production.env, depending on where you're deploying to

maxdevjs

#!/bin/bash

## about

# this does two things 1) provides a visual indicator when moving between panes
# 2) cleverly cycles between the previous pane on all windows across the session.
# NOTE this script does echo out every single tmux focus switch to a file in /tmp/
# so unless you turn your machine off every night you'll want to find some way of
# dealing with that.
