NoddyMix is the source of the latest and greatest from the Nigerian Music Industry. Users can make and share playlists. Logged in users get the additional ability to follow friends and stay updated on friend's activities in realtime

As an added bonus users get to use native-like mobile web-apps thanks to Sencha Touch

The Django project is missing the noddymix/settings_secret.py file. A template version is included for help in setting up the sensitive information needed by the project.

The Nodejs module is also missing the noddymix/apps/activity/nodejs/config.js file. A template version is included for help in setting up the sensitive information needed by project.

Sencha Touch is not included in this repository. You must download it from the Sencha Touch Website and add it to the noddymix/static/mobile/touch folder.

You will also need Sencha CMD to build your application. Downlad it from the Sencha CMD Website

Navigate to the directory noddymix/static/mobile/touch and run the command:

sencha app build production

This creates production data at noddymix/static/mobile/build/NoddyMix/production. Navigate to this directory and you will see that there is a file called cache.appcache. The problem is that iPhones seem to only pick up HTML5 cache changes with .manifest and not .appcache. Fix this by running:

mv cache.appcache cache.manifest

Navigate to noddymix/static/js/ you see a number (>10) JS files. To minimize the number of download requests a user's browser has to make, I combine all JS files and gzip it, using following commands:

cat jquery-1.10.1.min.js jquery-ui-1.10.3.custom.min.js jquery.tipsy.js apprise-v2.js utils.js contextMenu.js jquery.jplayer.min.js playlist.js global.js > compressed/compiled.js

cd compressed

gzip -c compiled.js > compressed.js

Navigate to noddymix/static/css and you see 1 CSS file. This CSS file is simply gzip'd.

gzip.c global.css > compressed/global.css

The static images and compressed css & js are uploaded to the appropriate AWS S3 bucket. Django's settings know to pick up files from there when not in DEBUG mode.

These instructions here are what I did on my Webfaction server.

Add the following lines to ensure all requests to www.noddymix.com are redirected to noddymix.com.

The mobile web-app will make direct requests to this server (as opposed to AWS S3 bucket) for static files. So redirect those requests to the appropriate production build location.

Access crontab with:

crontab -e

Edit it to perform following functionality:

• Setup PATH, PYTHONPATH, NODE_PATH to be used by cron's environment
• Restart apache every 30 minutes. This ensures minimal downtime (if at all)
• Run management command to update search indexes every 45 minutes.
• Run redis and nodejs watchdog scripts every 5 minutes to ensure realtime feed is always running
• Backup database daily using configurations hidden in config file [some values redacted]

The watchdog scripts are to keep the node.js and redis servers always running. These two services are needed for the realtime feed so downtime isn't acceptable.

#!/usr/bin/env bash

PIDFILE="$HOME/pid/redis.pid"

if [ -e "${PIDFILE}" ] && (ps -u $(whoami) -f | grep "[ ]$(cat ${PIDFILE})[ ]"); then
  echo "Already running."
  exit 99

• deploying nodejs
• deploying redis
  • place redis in a custom app and custom port
  • keep redis running with a cron watchdog script
  • more on running redis in background
  • restart redis
  • then use forever to keep node.js running [this fails if redis isn't up]
