MongoSchematic CLI

MongoSchematic is a modern, developer-first tool for MongoDB schema management. It helps you infer schemas from existing data, detect drift, generate code, and handle migrations with confidence.

Features

• Schema Inference: Automatically infer schemas from your MongoDB collections.
• Full BSON Support: All MongoDB types including binData, regex, long, timestamp, and union types.
• Drift Detection: Detect when your data deviates from your schema/models.
• Code Generation: Generate Pydantic models (Python) and TypeScript interfaces.
• Documentation: Build static HTML documentation for your database.
• Data Seeding: Populate your database with realistic dummy data.
• Migrations: Generate and execute versioned migration scripts.
• Validation: Validate documents against your defined schemas.
• AI-Powered: Optional Gemini AI integration for schema recommendations.

Installation

pip install mongo-schematic

Quick Start

1. Initialize

Generate a default configuration file:

mschema init

2. Analyze a Collection

Infer the schema from an existing collection and save it:

mschema analyze --collection users --save schemas/users.v1.yml

3. Generate Code

Create a Pydantic model for your application:

mschema generate models --schema schemas/users.v1.yml --type pydantic --out models/user.py

4. Detect Drift

Check if your live data matches your schema:

mschema drift detect --schema schemas/users.v1.yml --collection users
