Alibi Time Tracker

⚠️ This project is archived and not getting any (security) updates at the moment. It will remain available and public as an (possibly somewhat outdated) example of how to use Clojure and related tools.

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:

Features

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

Docker

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!"}}
EOF

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.
