A trying-to-be-small-but-useful Node.js tool to calculate DORA Metrics.

4 key metrics:

• Deployment Frequency - How often an organisation successfully releases to production
• Lead Time for Change - The amount of time it takes a commit to get into production
• Change Failure Rate - The percentage of deployments causing a failure in production
• Time to Restore Service - How long it takes an organisation to recover from a failure in production

The easiest metric to calculate - get a list of project deployments by environment and then group by date format(s) i.e. by day, by month and by year; and finally to calculate the throughput % score which is essentially:

throughput % = (count of deployments by environment * count of all deployments) * 100
