The Story of NPM and Yarn

In the beginning there was NPM, and for a time it was good. Packages went forth and multiplied. The New Gods proclaimed the great demon Dependency Management had been slain. But The Old Gods knew better, for they had seen much and knew that the demon can never be killed, only held at bay.

The Old Gods were ignored. In the folly of a young age grew an abundance of packages and with them grew the scourge of dependency. In the depths beneath the earth, in a place beyond memory, the great demon stirred.

The first sign something was wrong was non-deterministic package version mismatches. “This is fine!” The New Gods declared. “A temporary setback, nothing more! We can fix it.” And so they introduced shrinkwrap, a lamp to combat the growing darkness.

But it proved to be too little, too late, and dusk continued to fall. The New Gods suffered their first major defeat at the [Battle of Left-pad](https://www.theregister.co.uk/2016/03/23/npm_left_

JWT Auth + Refresh Tokens in Rails

This is just some code I recently used in my development application in order to add token-based authentication for my api-only rails app. The api-client was to be consumed by a mobile application, so I needed an authentication solution that would keep the user logged in indefinetly and the only way to do this was either using refresh tokens or sliding sessions.

I also needed a way to both blacklist and whitelist tokens based on a unique identifier (jti)

Before trying it out DIY, I considered using:

	-- Active issues
	-- Count of total active issues in the specified time frame
	-- Source: githubarchive public data set via Google BigQuery http://githubarchive.org/

	SELECT
	COUNT(DISTINCT JSON_EXTRACT_SCALAR(events.payload, '$.issue.id')) AS events_issue_count
	FROM (SELECT * FROM TABLE_DATE_RANGE([githubarchive:day.],TIMESTAMP('2015-09-01'),TIMESTAMP('2016-08-31')))
	AS events

	-- 10,723,492 active issues
