Any Postgres compatible ORM for Node.js? [closed]

Answer 1

https://www.npmjs.org/package/rdb
Simple, flexible mapper.
Transaction with commit and rollback.
Persistence ignorance - no need for explicit saving, everything is handled by transaction.
Eager or lazy loading.
Based on promises.
Well documented by (running) examples.

Answer 2

Would recommend trying Knex for the database and Bookshelf as an ORM on top of it (developed by same person). I'm using it with postgres, but supports SQLite, MySQL/MariaDB and Oracle (in alpha) too.

Very expressive promise-based API with bluebird behind it, knex has a well documented and great command line tool for making migrations, seed files etc. Bookshelf uses backbone models and collections as an inspiration, including the .extend(..) paradigm for inheritance, so picking it up is a breeze if you come from that world. So far, so good.

Answer 3

ORM's are a little too slow for fast nature of node.js; plain database driver is fine, but a little tiring. That's for I do write something just between: prego. It provides automatic statement preparation, migrations, simple models with associations, transactions and few utilities, all callback style and fast. Ideas/issues are welcome.

Answer 4

JugglingDB - multidatabase ORM inspired by activerecord and datamapper. Supports validations, hooks, relations. Works with: mysql, postgres, sqlite, memory, redis, mongodb, neo4j.

Not production ready now (march 2012), but growing fast. I plan stable release soon.

Answer 5

Missy is a universal ORM for both SQL and NoSQL databases which is simple, flexible, well-documented and supports some fancy features that other ORMs are lacking

Answer 6

node-orm2 looks good: supports association, validators, and mysql, postgres, and mongo (in beta)

UPDATE: The node-orm2 package is no longer maintained. Possible alternatives include bookshelf or sequelize.
