Last active January 2, 2016 21:08
Fastest and most lightweight method for starting a GUI based debugger I've ever seen. For node.js, this debugs your code using the Developer Tools in Google Chrome.

install

npm install -g node-inspector;

run debugger

node-inspector & ;
node --debug your/node/program.js;

Callback Hell

Callbacks are rampant in Javascript, this can cause what's known as "Callback Hell", or as I like to call. Rat nests. In the following example the "rat nest" is not that hard to follow along with, and that will be the case when your program is simple. But imagine when your program grows to have many rat nests, perhaps even the rat nests become intertwined. Messy.

rjcorwin / proxy-a-couchdb-with-another-service.js
Created February 7, 2014 17:09
Combine the CouchDB API with another HTTP API using Node.js http-proxy module.
var httpProxy = require('http-proxy')
var options = {
router: {
'mydomain.com/api': '127.0.0.1:8800', // -> Additional API possibly from an Express App
'mydomain.com/*': '127.0.0.1:5984', // -> CouchDB binded to the base so it behaves just like a CouchDB
}
}
