UtilityKnife is a web application that visualizes a user's Dropbox space usage/allocation as a treemap. It is similar to desktop programs like Windirstat, KDirStat, Disk Inventory X, Grand Perspective, and Space Monger.
UtilityKnife was built in under 40 hours by Kevin Conley and Carolynn Sullivan at the PennApps Fall 2013 hackathon.
UtilityKnife's visualization using the treemap from D3.js was heavily inspired by and built on Ben Garvey's Philadelphia budget visualization web application: http://budget.brettmandel.com/
- Python 2.7
- virtualenv (
pip install virtualenv)
- redis-server (
brew install redis)
- foreman (
gem install foreman)
After cloning the repository, create a virtualenv called "venv" and activate it:
virtualenv venv . venv/bin/activate
Then use the requirements.txt file to install the requirements for the app:
pip install -r requirements.txt
There are several important environment variables that must be defined for the app to work. These are listed in "secrets.py", and it is helpful when working locally to define them in a file called ".env" that foreman will load automatically:
DROPBOX_APP_KEY=fill_me_in DROPBOX_APP_SECRET=fill_me_in DROPBOX_APP_REDIRECT="http[s]://your_server.com:port/dropbox-auth-finish" FLASK_SECRET_KEY=fill_me_in
DROPBOX_APP_* secrets come from the Settings page of your Dropbox app on the Dropbox developer website. If you haven't already, you need to create such a Dropbox app. Make sure to set the permission type to "Full Dropbox" so UtilityKnife can analyze your entire Dropbox folder. You also need to add the relevant "Redirect URI" to your app's settings page to match the
DROPBOX_APP_REDIRECT secret. For example, when I run the app locally on my computer I use
Likewise, it is important to define these environment variables for the production server if you will upload it to somewhere like Heroku.
Running the App
First, open a terminal and start the redis server:
Then, open another terminal and start the app with:
If all goes well, you should be able to access the app locally at
