Minimal, database agnostic Models for Node.js (and the Browser)
Minimal, database agnostic Models for Node.js and the Browser.
The idea is to implement a Domain Model System that is persitence agnostic, to be used only for validation, type casting, transormations, and business logic. By using
minimodel, persintence (if relevant) has to be delegated to an external component (e.g. DAO/Services).
- The same model can be retrieved from different data sources
- Easily reuse the same models in the Browser
- Custom persitence allows more fine grained and powerful queries (instead of using an imposed ORM style querying system)
- Define schemas with a syntax similar to Mongoose's
- Type checking/casting
- Custom getters/setters

1 - Experimental
Please try it out and provide feedback.
- Breaking changes:
validate()is now an async function. A callback could be given as argument otherwise a promise will be returned.
