Nightly dependency-license inventory snapshot to Postgres
Each night, walks every tracked repository's lockfile, records each dependency and its resolved license into a Postgres table.
How it runs
The automated pipeline, trigger to output.
- TriggerNightly schedule
- ActionList repositories and fetch each lockfileGitHub
- ActionResolve SPDX license for every dependencyHTTP webhook
- ActionUpsert per-package license rows into PostgresPostgres
- OutputWrite snapshot summary row with copyleft/unknown countsPostgres
What it does
Builds and maintains a queryable license inventory. On a nightly schedule it enumerates your repositories, reads each lockfile, resolves every dependency's license, and upserts the full set into a Postgres table keyed by repo, package, version, and snapshot date. Over time this becomes a historical record you can diff to see exactly when a copyleft package entered the tree.
When to use it
Use it when you need an auditable, point-in-time source of truth for legal or compliance teams, or when you want to run ad-hoc SQL like "which repos pulled in an AGPL package this quarter." Complements a PR gate by giving you the long view.
How it works
- 1A nightly schedule triggers the run.
- 2The flow lists target repositories and pulls the current lockfile from each.
- 3It resolves the SPDX license for every dependency in every lockfile.
- 4Each row (repo, package, version, license, snapshot timestamp) is upserted into the Postgres inventory table.
- 5The final step writes a snapshot summary row recording total packages and count of copyleft/unknown licenses for trend reporting.
Set it up
What you configure once, before turning it on.
- 1Connect GitHubRepos, issues, pull requests, actions.
- 2Connect PostgresAny Postgres URL — query, write, migrate.
- 3Connect HTTP webhookTrigger any URL on agent actions.
- 4Set each agent's modelWe leave models unset so you pick the tier — fast + cheap, or top-quality.
- 5Tune it to your dataEdit the prompts, filters, and field mappings so it matches how your team works.
- 6Test, then turn it onRun once against a sample, confirm the output, then enable the trigger.
