##TXN

###Dev Startup

nf start -x 8080 -e env/dev.env

###What

Messing around with various APIs (Stripe), technologies (AJAX calls w/ client side jQuery), and monitoring and analytics platforms.

For example, wouldn't it be cool if you set an SMS alert to notify you when there's a new craigslist post on super hard-to-find apartments in SF?

Or if you receive a payment on Stripe, send a Twitter message saying #WINRAR ?

###Integration list

• Stripe: API, library
• Twitter: API, library
• NewRelic: library
• Google Analytics: docs

###Stack

• Javascript library: jQuery
• Templating engine: handlebars.js
• MVC framework: express
• Server side language: node.js
• Object-relational mapping: sequlize.js
• Database: PostgreSQL

###Install

Clone the repository

$ git clone https://github.com/skilbjo/txn.git

Install modules and dependencies

$ npm install

Add secret API keys from the super secret email

$ vim .env

Configure the database (assuming postgres is running at /usr/local/var/postgres)

$ postgres -D /usr/local/var/postgres

Ensure the following returns a list of dbs:

$ psql

> skilbjo=# \list

Configuration is now done... time to run the app :D

$ node server.js

Then view the app your browser: http://localhost:8080

###Deploy

git commit -am 'heroku' && git push && git push heroku master

heroku ps

heroku logs -t

heroku open

###Follow Up

• Switch to jade for templating
• Twilio API
• Paypal API
• Write tests (make tests, Makefile)
• Use Flash messages

###Useful tricks

If for some reason you get something like this:

events.js:72
        throw er; // Unhandled 'error' event
              ^
Error: listen EADDRINUSE

there are likely two node servers running. Close a terminal window and start again. But in case that doesn't work... $ killall node

Another issue gets you this error:

events.js:72
        throw er; // Unhandled 'error' event
              ^
Error: failed to connect to [localhost:27017]

Just run this: $ postgres -D /usr/local/var/postgres --fork or $ postgres -D /usr/local/var/postgres to start the database (and to kill the database process, run $ killall postgres)
