Using CouchDB with node.js

First, get yourself a CouchDB! You can get a free hosted CouchDB in seconds or download a binary from the Couchio downloads page.

Next, install npm because all awesome node packages are in npm :)

Node has better support for HTTP than any language I've ever worked with and coincidentally CouchDB's interface is solely accessible via HTTP. First, let's just talk to CouchDB using an HTTP library and later we'll look at some higher level abstractions.

npmcount output for groups of node.js thought leaders

• Nodejitsu
• Browserling
• LearnBoost
• Node.js Core team

This list has been computed using a silly tool I developed on a lark called npmcount:

• Search npm for packages belonging to a set of users.

module.exports = and ES6 Module Interop in Node.js

The question: how can we use ES6 modules in Node.js, where modules-as-functions is very common? That is, given a future in which V8 supports ES6 modules:

• How can authors of function-modules convert to ES6 export syntax, without breaking consumers that do require("function-module")()?
• How can consumers of function-modules use ES6 import syntax, while not demanding that the module author rewrites his code to ES6 export?

@wycats showed me a solution. It involves hooking into the loader API to do some rewriting, and using a distinguished name for the single export.

This is me eating crow for lots of false statements I've made all over Twitter today. Here it goes.
