Minor Changes

• #182 251d641 Thanks @threepointone! - Prevent unbounded KV namespace growth with TTL defaults, cascade deletes, and garbage collection.

  Default TTLs to prevent unbounded storage growth:

  • refreshTokenTTL now defaults to 30 days (previously infinite). Grants auto-expire via KV TTL. Set to undefined explicitly to restore the previous behavior of never expiring.
  • clientRegistrationTTL (new option) defaults to 90 days. Dynamically registered clients (DCR) auto-expire. Clients created via OAuthHelpers.createClient() are not affected. Set to undefined for clients that never expire.

  deleteClient() now cascades to grants and tokens:

  Previously, deleting a client only removed the client:{id} record, leaving all associated grants and tokens orphaned in KV. Now deleteClient() scans all grants, revokes those belonging to the deleted client (which also deletes their tokens), and then deletes the client record.

  New purgeExpiredData() method for scheduled garbage collection:

  Defense-in-depth cleanup method designed to be called from a Cron Trigger. Processes records in configurable batches (default: 50) to stay within Cloudflare's subrequest limits. Performs two sweep phases: (1) grant sweep removes orphaned grants (client deleted) and expired grants, (2) token sweep removes orphaned tokens (grant deleted). Safe for CIMD clients — grants with URL-based client IDs are never incorrectly treated as orphaned. Available on both OAuthHelpers (via env.OAUTH_PROVIDER.purgeExpiredData()) and directly on OAuthProvider (via oauthProvider.purgeExpiredData(env)) for use in scheduled handlers without a request context.

  New exports: PurgeOptions, PurgeResult
