Fast CouchDB setup in AWS

CouchDB is a NoSQL database for storing JSON documents. It comes with a REST API out of the box so your client applications can persist data while requiring you to write little or no server-side code. CouchDB's killer feature is its ability to easily replicate, which allows for horizontal scaling, easy backup, and for client adapters to synchronize documents. This is perfect if you want to write an application that is offline-first. It's become my go-to database when creating new

I've written numerous tiny databases. They don't have much features, but they don't need much features. Usually I'm looking for fast simple key/value stores and Node never disappoints. The point here is, why abstract key value store when JS gives us one for free, as it's most basic component: object.

Will it meet every need? No. But it will meet ALOT of scenarios.

In memory JS object lookups, were talking hundreds of thousands of lookups (you'll easily flood http before the db), and save hundreds of thousands of records in a JSON file written to disk. Not a 200ms r/t to some hosted Redis. Hey, that's fine if that's your thing.

Here's the requirements:

OBSOLETE

This entire guide is based on an old version of Homebrew/Node and no longer applies. It was only ever intended to fix a specific error message which has since been fixed. I've kept it here for historical purposes, but it should no longer be used. Homebrew maintainers have fixed things and the options mentioned don't exist and won't work.

I still believe it is better to manually install npm separately since having a generic package manager maintain another package manager is a bad idea, but the instructions below don't explain how to do that.

Installing node through Homebrew can cause problems with npm for globally installed packages. To fix it quickly, use the solution below. An explanation is also included at the end of this document.
