From zero to your first Garmin data in Node

Two distinct methods exist for accessing Garmin Connect data. Developers can utilize garminconnect-js, a typed, zero-dependency Node client, to build applications that read and write data, including MFA handling and session management. Alternatively, non-programmers can connect their Garmin watch to Claude using a free connector. This allows users to analyze sleep, heart rate, and training recovery through plain language queries without coding or installations, bypassing the need to manually navigate complex charts.
