Before:
Revalidation was turned off entirely for wrappers pages, and done daily for GraphQL pages.
After:
Revalidation is via tag. There is an /api/revalidate endpoint that is used by GitHub Actions on the federated repos to trigger the revalidation. This decreases the number of unnecessary page generations by Vercel, and gives the maintainers of federated repos more fine-grained control over when to reploy their docs (see the docs deployment playbook for more info).
Add a route for manually revalidating cache contents by tag.
The route is protected by authentication to prevent abuse. Automated
actions in CI should be set up with a basic API key, which has a rate
limit of 6 hours between changes. Overriding is possible with an
override key, which should be used as an escape hatch.
Usage:
- API key provided in header `Authorization: Bearer <KEY>`
- Body has shape `{ tags: string[] }`
