How to Use
- Select your database dialect (PostgreSQL, MySQL, or SQLite)
- Paste your SQL CREATE TABLE statements into the input area
- Click "Generate MikroORM Entity" to create the TypeScript entity classes
- Copy the output and save it as a .ts file in your MikroORM project

Tips & Best Practices
- SERIAL columns are mapped with autoincrement: true
- Foreign key references generate @ManyToOne decorators
- TypeScript types are inferred from SQL column types
- JSONB columns map to type "any" for flexible data structures
Frequently Asked Questions
What is MikroORM?
MikroORM is a TypeScript ORM for Node.js based on the Data Mapper, Unit of Work, and Identity Map patterns. It provides a clean and intuitive API for database operations with automatic transaction management and change tracking.
How are SQL types mapped to MikroORM types?
SQL types are mapped to MikroORM property types and columnType options. For example, VARCHAR maps to type string with columnType varchar, INTEGER maps to type number with columnType integer, TIMESTAMP maps to type Date.
Does it support relations?
Yes, REFERENCES constraints generate @ManyToOne decorators with the referenced entity type. You can manually add @OneToMany on the other side for bidirectional relations.
Is my SQL data sent to a server?
No, all processing happens entirely in your browser. Your SQL schema never leaves your device.
