## What it is
node-orm2 (npm package 'orm') is an object-relational mapping library for Node.js supporting MySQL/MariaDB, PostgreSQL, Amazon Redshift, SQLite, and beta MongoDB. It provides model definition, associations, validations, instance caching, and plugins for pagination, transactions, timestamps, and migrations.

## Use cases
- map javascript objects to relational database tables in node.js
- define models with validations and associations in node
- query mysql or postgresql without writing raw sql
- sync and drop database schemas from node models
- add pagination and transactions to a node.js orm

## When to choose
- maintaining a legacy node.js codebase already using the orm package
- you need a lightweight callback-style orm for mysql, postgres, or sqlite

## When to avoid
- starting a new project - the readme recommends TypeORM or Sequelize instead
- you need MongoDB support on modern node versions
- you need active community support or recent features

## Facets
- artifact type: library
- maturity: maintenance
- function: orm, database, database-driver
- domain: databases, backend, web-development, developer-tools
- platform: -
- tags: mysql, postgresql, sqlite, redshift, mongodb, model-associations, validations, not-actively-maintained, nodejs, javascript
