Database Migrations

This directory contains database migrations for the Wedding Photo Sharing platform.

Directory Structure

/core

Essential migrations that are always run for new deployments. These include:

  • init.js - Initial database schema creation
  • Backup service tables (029-035)
  • Gallery feedback tables (033)

/legacy

Migrations needed only when upgrading from older versions. New deployments can skip these as the core schema already includes all necessary tables and columns.

For New Deployments

If you're deploying this application for the first time:

  1. The initializeDatabase() function in src/database/db.js will create all necessary tables
  2. Only migrations in the /core directory will be run
  3. This ensures a clean, optimized database schema

For Existing Deployments

If you're upgrading from an older version:

  1. All migrations (both core and legacy) will be run in sequence
  2. The migration system tracks which migrations have been applied
  3. Only new migrations will be executed

Running Migrations

# Development
npm run migrate

# Production
npm run migrate:prod

Note on Duplicate Migration Numbers

The legacy directory contains renamed duplicates:

  • 014_add_host_name_to_events_duplicate.js (was duplicate of 014)
  • 027_add_rate_limit_settings_duplicate.js (was duplicate of 027)

These have been renamed to avoid conflicts while preserving the migration history.
