Alibi Time Tracker

A time tracker for developers, written in Clojure.

This is the source code for a time tracking solution we use at Infi. It is written in Clojure(Script), and uses a lot of Domain-Driven Design principles. As such, it aims to provide an example codebase for a realistic Clojure application, a realistic DDD application and the both of them together. That being said, there are probably a lot of issues with this code base from both a Clojure as well as a DDD point of view. I'm happy to hear about these, so we can improve this codebase.

I wrote some rationale about the goals and design/architecture at:


This is far from a fully fledged time tracker, yet it has the following features, and more is on the way!

  • Categorize time entries by project and task.
  • Graphical overview of your weekly activity.
  • Indicate whether entries are billable or not.
  • Tasks have an associated billing method, either fixed price, overhead or hourly.
  • Create projects and tasks via a CLI, and the repl.
  • Extension points for a different data source implementation.
  • OpenID Connect and single user authentication.
  • Out of the box Sqlite3 database support.

Getting started


If you just want to play around a little you can do that by running the docker image:

docker run -p 3000:3000 infinl/alibi-demo

Open http://localhost:3000 in the browser and you should be able to fiddle around.

Run with leinigen

The prerequisites for this route are:

  • Have a git client installed.
  • Make sure Java is installed (leinigen, see next step, needs it).
  • Make sure leiningen is installed.
  • Have npm installed

Clone the repo. Then, inside the repo, create a sqlite db:

lein run sqlite create-db :filename "alibi.db"

This will create a sqlite3 db with filename alibi.db, which contains the right schema, but has no data. Before we create some data, you first need to setup a config file, and for that you need to create a key for cookie encryption, e.g. using:

openssl rand -base64 12

Then execute the following to create a config file, replacing the :cookie-encryption-key value with your own key and [:sqlite :subname] with the database file you picked in a previous step.

cat << EOF > config/local/config.edn
{:cookie-encryption-key "xxxxxxxxxxxxxxxx"
 :selmer-caching? false

 :persistence :sqlite
 :persistence-strategies {}
 :sqlite {:subprotocol "sqlite" :subname "alibi.db"}

 :authentication :single-user
 :single-user {:username "me!"}}

Have a look at config/config.edn for more config options, including how to use OpenID Connect for authentication.

Now we can populate the database with some projects and tasks:

lein with-profile local run projects create :name "Alibi" :billing-method :hourly
# => Will return an id for the newly created project, use that for "1" in the following steps
lein with-profile local run tasks create :name "Project management" :for-project 1 :billing-method :overhead
lein with-profile local run tasks create :name "Programming" :for-project 1

Install client dependencies

npm install && ./node_modules/.bin/grunt copy

Compile the ClojureScript:

lein cljsbuild once

Run the server:

lein with-profile local ring server-headless

If everything went well, there should now be a web server running on http://localhost:3000. Navigate to it and have fun!

Building a Docker image

You can run Alibi in a Docker:

docker build . -t infi/alibi

# Create project "Alibi" with one regular and one overhead-task
docker run -v /local/path/to/data:/opt/alibi/data infi/alibi app:projects create :name "Alibi" :billing-method :hourly # returns <id>
docker run -v /local/path/to/data:/opt/alibi/data infi/alibi app:tasks create :name "MyTask" :for-project <id>
docker run -v /local/path/to/data:/opt/alibi/data infi/alibi app:tasks create :name "MyOverheadTask" :for-project <id> :billing-method :overhead

# Run the application
docker run -v /local/path/to/data:/opt/alibi/data -p 3500:3000 infi/alibi

Alibi should now be running at http://localhost:3500.


This project uses a lot of open source tooling, which I am grateful for. In no particular order:

  • Clojure(Script)
  • ring
  • compojure
  • celmer
  • clj-time
  • bouncer
  • MySQL
  • Jetty
  • Buddy
  • Sqlite3
  • Figwheel
  • Sablono
  • Cljsbuild
  • Cider
  • JSJoda
  • Selectize
  • JQuery
  • React
  • Leiningen
  • Om
  • Grunt

If you find your project in the source, but isn't listed: I'm sorry! Please drop me a note and I'll add yours.
