Strengths & Weaknesses
↑ Strengths
↓ Weaknesses
Lowdb stores all data in memory and performs operations synchronously, which can lead to performance degradation with larger JSON files.
As a single-file database, Lowdb does not handle concurrent reads and writes well, potentially leading to data corruption or loss in multi-threaded applications.
Lowdb relies on Lodash for operations which limits complex query functionalities compared to more robust databases like MongoDB or PostgreSQL.
Users must implement their own data backup solutions, as Lowdb does not provide any out-of-the-box features for backing up JSON files or recovering from failures.
