Is there a good DAL or DAL/ORM for Node.js yet?

I want to experiment a bit with Heroku and Node.js. Heroku uses Postgres by default but I would like the option to use Amazon RDS later on (MySQL). Is there a good database abstraction layer, prefe开发者_如何学编程rably with a simple object relational mapper around it available at this point? I checked the NPM repository, but couldn't find something that supported both, looked mature and was well documented.

You might be interested in using another hosting provider. For example Duostack is super easy to set up and allows the usage of mysql: http://docs.duostack.com/node/databases#mysql

An ORM for MySQL is e.g. sequelize ( http://sequelizejs.com | https://github.com/sdepold/sequelize ).
