## What it is
DreamJS is a lightweight JavaScript library for generating random JSON data from schemas. It supports standard types plus 60+ built-in custom types (via Chance) and allows defining custom types and named, chainable schemas.

## Use cases
- generate mock  data for tests
- create random user records from a schema
- seed a database with fake data
- generate sample api responses
- produce random names, addresses, and other fake fields

## When to choose
- you need lightweight schema-based fake JSON data in Node.js
- you want Chance-style random types with custom type support
- you need simple chainable schema definitions for mock data

## When to avoid
- you need actively maintained tooling with modern Promise/Stream support
- you need locale-aware or highly realistic faker data
- you work outside the Node.js/npm ecosystem

## Facets
- artifact type: library
- maturity: maintenance

- tags: fake-data, -schema, mock-data, chance, random-data, data-engineering, nodejs, javascript
