According the Mandrill's docs (http://help.mandrill.com/entries/21738166-API-Wrappers), mandrill-api-node is the official node client. It's not available on npm, only BitBucket:

npm install git+https://bitbucket.org/mailchimp/mandrill-api-node.git --save

However, there is also a third party wrapper they list on the above-mentioned page and also provide an example for (https://mandrillapp.com/api/docs/index.nodejs.html). This can be installed as follows:

npm install mandrill-api --save

A simple starter script to copy a node app to a remote host and start it over ssh.

Not very robust in terms of order-dependent argument handling. Arguments have defaults, but if you provide a value for one, any preceding args must also be supplied.

Arguments

1. The source directory. Defaults to current directory.
2. The destination server for the ssh connection.
3. The port to run the app on the destination server. Defaults to port 80.

Sometimes you want to wrap error objects with application-specific errors for your stack traces.

Your custom error constructor:

function CustomError(e, extra) {
  Error.call(this);
  Error.captureStackTrace(this, CustomError);
  this.id = e.id;
 this.name = 'CustomError';

It's easy enough to load json files in Node, but what's nice about nconf is it neatly takes care of mundane issues and provides a nice way of hierarchically designating the precedences of settings. For example, it is trivial to specify that application args will override environment settings, which will override any configuration file settings, which will override any application defaults.

This is more of a memory aid to myself. It's best to check out the full documentation the first time through to familiarize yourself with all that nconf has to offer.

Definitely not comprehensive. This is meant to be a basic memory aid with links to get more details. I'll add to it over time.

Install

$ npm install mongoose --save

Connect

const mongoose = require('mongoose');

Just a quick and dirty memory aid for common things.

Undo, Redo, and Repeat

Action	Keys
Undo	u or :u
Undo all changes to line	U
Redo undone change	Ctrl-R or :red[o]
Repeat last command	.

Just a basic memory aid.

Create keys

Create a new key using the email address as label

$ ssh-keygen -t rsa -C "name@example.com"

Accept the default name (~/.ssh/id_rsa) or provide another for multiple identities

You can load helper functions from a JavaScript file to make working with data in the mongo shell easier.

I typically like to create a queries.js file that contains a number of helper functions. You load a file in the shell like this:

> load('queries.js')

Since I keep editing the file and adding more helpers as I'm working, I usually add a helper function to the file that reloads itself to save a few keystrokes. Yup, I'm that lazy.

Install with Homebrew

brew install mongodb

Set up launchctl to auto start mongod

$ ln -sfv /usr/local/opt/mongodb/*.plist ~/Library/LaunchAgents

/usr/local/opt/mongodb/ is a symlink to /usr/local/Cellar/mongodb/x.y.z (e.g., 2.4.9)
