What is SQL to Sequelize Model Converter?
This tool converts SQL CREATE TABLE statements into Sequelize model definitions. Sequelize is a promise-based Node.js ORM for PostgreSQL, MySQL, MariaDB, SQLite, and Microsoft SQL Server. The converter generates JavaScript or TypeScript code using Sequelize.define() or Model.init() syntax.
How to Use
- Select your database dialect (PostgreSQL, MySQL, or SQLite)
- Choose output language: TypeScript or JavaScript
- Paste your SQL CREATE TABLE statements into the input area
- Click "Generate Sequelize Model" to create the model definitions
- Copy the output and save it in your Sequelize project
Why Use This Tool?
Tips & Best Practices
- SERIAL columns are mapped with autoIncrement: true
- Foreign key references generate references configuration
- TypeScript output includes model interfaces and creation attributes
- JavaScript output uses sequelize.define() for simplicity
Frequently Asked Questions
What is Sequelize?
Sequelize is a promise-based Node.js ORM that supports multiple SQL dialects. It provides model definitions, associations, migrations, and a powerful query API for database operations.
How are SQL types mapped to Sequelize DataTypes?
SQL types are mapped to Sequelize DataTypes based on the selected dialect. For example, VARCHAR maps to Sequelize.STRING, INTEGER maps to Sequelize.INTEGER, TIMESTAMP maps to Sequelize.DATE.
What is the difference between TypeScript and JavaScript output?
TypeScript output includes model interfaces, creation attributes, and a Model class with proper type annotations. JavaScript output uses the simpler sequelize.define() syntax without type information.
Is my SQL data sent to a server?
No, all processing happens entirely in your browser. Your SQL schema never leaves your device.
