Sometimes you have to fail hard

This was a post I wrote in the middle of 2013 but never published. I wanted to share this since it’s a common story across all technologies and developers of all skill levels. Sometimes things really just don’t work. As a post-script, I did come back to this project and had a lot of success. When in doubt, let time figure it out :)

For the last couple of weeks, I’ve been trying my hand at the node.js ecosystem. I had an app idea but I wanted to make sure I chose tech stacks wisely. There’s no better way to get familiar with different stacks than to get your hands dirty and try them all, so that’s what I did.

Sometimes when you start with a new language or platform things come easy, you can blaze a burning trail writing great software. You’re like an extension of the computer, everything … Read more

Separation of concerns in node.js

I’ve been playing with typescript and node.js and I wanted to talk a little about how I’ve broken up my app source. It’s always good to modularize an application into smaller bits, and while node lets you do a lot, quickly, with just a little bit of code, as your application grows you really can’t put all your logic in one big app.ts.


Instead of the normal application example you see for node projects, I wanted to make it clearer what the initialization of my application does. My app start is structured like this:

* Module dependencies.

import db = module("./storage/storageContainer");
import auth = module("./auth/oauthDefinitions");
import requestBase = module("./routes/requestBase");

var express = require(‘express’)
, routes = require(‘./routes’)
, http = require(‘http’)
, path = require(‘path’)
, log = require("./utils/log.js")
, fs = require(‘fs’)
, passport = require(‘passport’);

var app = express();

class AppEntry{
this.initDb();… Read more

Event emitters with success and fail methods for node.js

When it comes to node.js you hear a lot of hype, good and bad, so I’ve finally decided to take the plunge and investigate for myself what the fuss is about. So far it’s been interesting.

I’m not really building anything in particular right now, I’m just playing with different tech stacks to see how things are done. One of the things that I found I liked, while experimenting with node modules, is the syntax success and fail for callback registration. Something like this:

      .success(function() { })
      .fail(function() { });

Using this kind of syntax I wanted to have a basic user authentication forwarder that I could wrap route calls in such that only logged in users could call the route. Non logged in users would automatically be forwarded to a twitter oauth route for auto login (done using everyauth).

The first step was to create a custom … Read more
