What is SQL to Mongoose Schema Generator?
This tool converts SQL CREATE TABLE statements into Mongoose schema definitions. Mongoose is a MongoDB object modeling tool designed to work in an asynchronous environment. The converter generates JavaScript or TypeScript code with proper schema definitions, type mappings, and model exports.
How to Use
- Choose output language: TypeScript or JavaScript
- Paste your SQL CREATE TABLE statements into the input area
- Click "Generate Mongoose Schema" to create the schema definitions
- Copy the output and save it in your Mongoose/MongoDB project
Why Use This Tool?
Tips & Best Practices
- SERIAL columns are mapped to Number type
- Foreign key references generate ObjectId with ref property
- JSONB columns map to Schema.Types.Mixed
- TypeScript output includes proper interface definitions
- JavaScript output uses module.exports for compatibility
Frequently Asked Questions
What is Mongoose?
Mongoose is a MongoDB object modeling tool for Node.js that provides schema-based solutions to model your application data. It includes built-in type casting, validation, query building, business logic hooks, and more.
How are SQL types mapped to Mongoose SchemaTypes?
SQL types are mapped to Mongoose SchemaTypes. For example, VARCHAR/TEXT maps to String, INTEGER/BIGINT maps to Number, BOOLEAN maps to Boolean, TIMESTAMP/DATE maps to Date, JSON/JSONB maps to Schema.Types.Mixed.
How are foreign keys handled?
Foreign key REFERENCES constraints are converted to ObjectId types with a ref property pointing to the referenced model. This enables Mongoose population and relationship management.
What is Schema.Types.Mixed?
Schema.Types.Mixed is a flexible Mongoose type that can hold any value. It is used for JSON/JSONB columns from SQL, allowing you to store arbitrary JavaScript objects in MongoDB.
Is my SQL data sent to a server?
No, all processing happens entirely in your browser. Your SQL schema never leaves your device.
