This Node.js script facilitates data migration from a MySQL database to a PostgreSQL database. It automates creating tables, indexes, foreign keys, and data insertion while maintaining data integrity.
- Node.js installed
- MySQL and PostgreSQL servers running
mysql2andpgNPM packages installed
Set up your database connection details at the beginning of the script:
// MySQL configuration
const mysqlConfig = {
host: 'localhost',
user: 'root',
password: 'root',
database: 'users',
port: 3306
};
// PostgreSQL configuration
const postgresConfig = {
host: 'localhost',
user: 'postgres',
password: 'postgres',
database: 'users',
port: 5432
};- Converts MySQL data types to PostgreSQL-compatible types.
- Creates tables, primary keys, indexes, and foreign keys in PostgreSQL.
- Migrates data with null value handling and type conversion.
- Detailed migration process logging.
- Adjust the connection settings for your databases.
- Run npm install && npm run start
- Monitor the process as the script migrates each table.
- Supports auto-increment fields, enumerations, and JSON fields.
- SSL configuration for PostgreSQL is available but commented out.
- Assumes no restrictive constraints in MySQL that hinder direct migration.
