Score: 7.0/10 (Innovation: 6, Technical: 7, Documentation: 8, Utility: 7)

calsdk provides a unified TypeScript API for reading, writing, and syncing events across nine calendar providers including Google, Outlook, iCloud, and CalDAV. It abstracts away provider-specific quirks like recurrence formats, time zones, and sync cursors, with a mock adapter for testing and typed error classes. The project is interesting for its cross-provider free-time search and a pluggable provider conformance suite.

Target audience: backend and full-stack TypeScript developers building scheduling features
