postgres-entities

A library for storing structured JSON documents with versioning, etag/last-modified tracking, and zero-downtime migration support in PostgreSQL. Current stable version is 1.1.3, under initial development. Designed as a replacement for Azure Entities, it targets Node.js >=10 and focuses on redeployability, data visibility, and reliable optimistic concurrency via automatic etag and last-modified columns. Key differentiators include a human-readable storage format, table-level stored procedures for atomic updates, and built-in migration flow supporting multiple schema versions.
