RetroGit

Service that shows you your GitHub commits from previous years. Includes a mail digest to that you can see each day what you were up to in the past.

It's currently running at https://www.retrogit.com/.

Running Locally

1. Install Go 1.25 and a current Google Cloud CLI.

2. Install the App Engine local development server component:

gcloud components install app-engine-python

3. Authenticate if you need local access to Google Cloud services:

gcloud auth login
gcloud auth application-default login

4. Create github-oauth.json (you'll need to register a new app with GitHub) and session.json (with randomly-generated keys) files in the config directory, based on the sample files that are already there.

5. Run the local App Engine development server:

./dev.sh

The server can then be accessed at http://localhost:8080/.

The local development server simulates App Engine bundled services such as Datastore, Memcache, Mail, and Task Queues.

Deploying to App Engine

./deploy.sh

deploy.sh deploys app.yaml and queue.yaml. Deploy cron.yaml separately only when cron configuration changes.
