fb-sleep-stats: Using Facebook to track your friends' sleep

A small tool to show the potential privacy implications modern social media have. By tracking online/offline status of people on Facebook, it is possible to get an accurate image of their sleep pattern.

Facebook Sleep Screenshot

Installation

Prerequisites

Clone repository

git clone https://github.com/sqren/fb-sleep-stats.git

Configuration

Open the source code folder:

cd fb-sleep-stats

Copy the default config file:

cp config/default.json config/development.json

Update the following values in config/development.json

Make sure there are no trailing tabs or spaces in the config file!

Install dependencies

npm install

Build browser dependencies

npm run webpack

Starting

You need to have two processes running simultaniously: the scraper and the webserver. Therefore, you must run the following two commands in separate windows/tabs.

Start scraping

This will run continously, polling Facebook every 10 minutes. Keep it running for as long as you want to track sleep.

npm run scrape

Start server

npm start

See the result in the browser: http://localhost:3000

#Troubleshooting

I get an error when running "npm run webpack"

Try re-installing the node-modules:

rm -rf node_modules
npm install
npm run webpack

No users show up

  • If you have an ad-blocker, you must disable it for the site.
  • You need to run npm run scrape and keep it running. When you stop it, it will stop tracking.

Changes to development.json are not picked up

  • You have to run npm run webpack

How do I update to the latest version?

After pulling the latest version, you must rebuild the dependencies:

git pull
rm -rf node_modules
npm install
npm run webpack

ReferenceError: Promise is not defined

Update Node.js to the latest stable version of the branch you are on (v5.7.1, v4.3.2 or v0.12.11). After that rebuild dependencies:

rm -rf node_modules
npm install
npm run webpack

Cannot parse config file

Your config file contains invalid json. Find the errors by using a tool like http://jsonlint.com/

Where is the data stored?

You can find the data in JSON-format here: src/server/services/db.json.
