## What it is
Massive.js is a data mapper library for Node.js that provides a thin, promise-based interface over PostgreSQL, letting developers work with tables, queries, and functions as first-class objects. It emphasizes writing SQL directly while handling connection management and result mapping.

## Use cases
- query postgres from nodejs
- data mapper for postgresql
- write raw sql in node without an orm
- access postgres tables and functions from javascript
- promise-based postgresql client

## When to choose
- you prefer writing SQL over ORM query builders
- you want a lightweight data mapper instead of a full ORM
- your stack is Node.js with PostgreSQL

## When to avoid
- you need multi-database support beyond PostgreSQL
- you want a full-featured ORM with migrations and schema management
- you are not using Node.js

## Facets
- artifact type: library
- maturity: maintenance
- function: database, orm, database-driver
- domain: databases, backend, web-development
- platform: windows
- tags: postgresql, data-mapper, sql, promise-based, nodejs, linux, macos
