Walkthrough

This PR updates the CloudFlare class in cloudflare.js by modifying the uploadTlsClientAuth method to include a new clear parameter. When clear is set to true, existing custom client and CA certificates are cleared before proceeding with an upload. The update adds new methods to retrieve certificate IDs (getClientCerts, getCaCerts) and to delete certificates by their IDs (deleteClientCert, deleteCaCert), along with a dedicated method (clearCustomCerts) to handle the clearance process.

Changes

File	Change Summary
cloudflare.js	Modified uploadTlsClientAuth to include a clear parameter. Added methods: clearCustomCerts, getClientCerts, getCaCerts, deleteClientCert, and deleteCaCert with error handling.

🧹 Nitpick comments (3)

cloudflare.js (3)

812-829: Consider handling partial certificate arguments more explicitly.
Currently, the code only proceeds when all three of clientKey, clientCert, and caCert are provided. If partial updates or error feedback on missing parameters are needed, a refactor may be beneficial.

---

831-850: Fix mismatch in console error message for CA cert deletion.
The second loop logs "Failed to delete Client cert" even though it is deleting CA certs. Consider applying this change:

-        console.error(`Failed to delete Client cert: ${e?.message}`)
+        console.error(`Failed to delete CA cert: ${e?.message}`)

---

807-918: Add tests for new cert handling methods.
The new methods (clearCustomCerts, getClientCerts, getCaCerts, deleteClientCert, deleteCaCert) and the updated uploadTlsClientAuth could benefit from dedicated tests to ensure coverage and prevent regressions.
