Memory-ORM

An in-memory client-side ORM with map-reduce capabilities for JavaScript, version 0.7.0 (appears stable, low release cadence). It allows defining schemas with associations (has_many, belongs_to), querying data via Set and Query objects, and performing map-reduce aggregations (count, avg, min, max, variance, etc.). Differentiators: built-in map-reduce engine for client-side data analysis, schema-based relationships, and ordering/filtering operators. Works in Node.js and browser. Ships TypeScript types. Not to be confused with server-side ORMs like Sequelize or TypeORM.
