Install a dev dependency, then install a production dependency that (internally) depends on that same dev dependency. (Should you have to know that? Is that not an implementation detail?)

Then shrinkwrap for production, and note the missing nested dependency.

npm init
npm install [email protected] --save-dev
npm install strong-agent --save
npm shrinkwrap

Install a production dependency, then install a dev dependency that the production dependency (internally) depends on as well. (Should you have to know that? Is that not an implementation detail?)

Then shrinkwrap for production, and note that the dev dependency is (correctly) excluded at the top, but present nested under the production dependency.

npm init
npm install strong-agent --save
npm install [email protected] --save-dev
npm shrinkwrap

Streamline

We use Streamline.js to manage async control flow in Node. If you're new to Streamline, its introductory blog post frames it well. Be sure to read through the Streamline FAQ as well.

This is a Neo4j 1.9 (pre-2.0) query:

START user=node:nodes(type='user')
MATCH user <-[:follows]- follower -[?:follows]-> other
WITH user, follower, 1.0 / COUNT(other) AS weighted
WITH user, COUNT(follower) AS numFollowers, SUM(weighted) as totalWeighted
RETURN user, numFollowers,
  ROUND(totalWeighted * 100) / 100.0 AS totalWeighted,
 ROUND(totalWeighted * 100 / numFollowers) / 100.0 AS avgFollowerWeight

CoffeeScript 1.7 is shaping up to be a pretty kick-ass release with significant improvements. Here are the ones I'm most excited about, in order of my own excitement.

Parentheses-free chaining

jashkenas/coffeescript#3263

Years of being wished for, finally granted!

Keybase proof

I hereby claim:

I am aseemk on github.
I am aseemk (https://keybase.io/aseemk) on keybase.
I have a public key whose fingerprint is 8FD7 03E6 42A7 B1CD 6D50 07F4 4929 0166 F879 0B95

To claim this, I am signing this object:

Pattern 1: Pre-fetch the result, and cache it.

The result will hopefully already be available when needed, and the async call will be made only once.

fooFuture = fetchFoo !_

# anytime when needed:
foo = fooFuture _ # supports multiple calls!

	# Specifically, searches for gettext `__()` calls in our checked-in files.
