@megaorm/cli/dist/commands/RollbackCommand.d.ts

This package allows you to communicate with MegaORM via commands directly from the command line interface (CLI).

import { MegaCommand } from '../MegaCommand';
/**
 * Represents a command to rollback the most recently generated tables.
 *
 * The command performs the following actions:
 * - Resolves the configuration and establishes a connection to the database.
 * - Identifies the last batch of generated tables.
 * - Drops the tables created in the most recent generation batch.
 *
 * Example Behavior:
 * - If the first generation created 2 tables, and the second created 4 tables:
 *   - Executing the rollback will drop the last 4 tables created in the second generation.
 *
 * This ensures that rollbacks only affect the most recent changes, preserving earlier tables.
 *
