Release Notes

jdesboeufs/connect-mongo (connect-mongo)

v6.0.0

Compare Source

• Breaking: Requires Node.js 20.8+ (aligns with MongoDB driver 5–7 support).
• Compatibility: Supported/tested matrix: Node 20/22/24 + MongoDB driver 5.x–7.x + MongoDB server 4.4–8.0 (peer range remains >=5.0.0).
• Added: Optional timestamps flag to record createdAt/updatedAt on session documents for auditing while keeping the default schema unchanged.
• Added: Pluggable cryptoAdapter interface with helpers createWebCryptoAdapter (AES-GCM via Web Crypto API) and createKrupteinAdapter; legacy crypto options are auto-wrapped and mutually exclusive with cryptoAdapter to avoid ambiguity.
• Fixed: store.clear() now uses deleteMany({}) instead of collection.drop(), preserving TTL indexes and treating NamespaceNotFound as success so clears are idempotent.
• Fixed: Decryption failures in get() now short-circuit after the first callback, preventing double-callback regressions when the crypto secret is wrong.
• Packaging: npm package now ships dual ESM/CJS bundles via tsdown, with an explicit exports map and cleaned type declarations (.d.mts/.d.cts).
• Types: MongoStore and option hooks are strongly typed to avoid any leaks.
