🚀 Usage

Basic Usage

Squash all migrations before a specific date, keeping the 10 most recent:

php artisan migrations:squash

Preview Changes (Dry Run)

See what would be squashed without making any changes:

php artisan migrations:squash --dry-run

Custom Options

# Squash migrations before specific date
php artisan migrations:squash --before=2024-01-01

# Keep specific number of recent migrations
php artisan migrations:squash --keep=15

# Disable backup creation
php artisan migrations:squash --no-backup

# Delete migration records from database
php artisan migrations:squash --delete-records

# Combine multiple options
php artisan migrations:squash --before=2023-06-01 --keep=20 --dry-run

⚙️ Configuration

The config file provides several options:

return [
    // Date before which migrations will be squashed
    'squash_before' => env('MIGRATION_SQUASH_BEFORE', '2024-01-01'),

    // Number of recent migrations to keep separate
    'keep_recent' => (int) env('MIGRATION_SQUASH_KEEP_RECENT', 10),

    // Name of the generated schema dump file
    'schema_file' => '0000_00_00_000000_schema_dump.php',

    // Create backup of squashed migrations
    'backup_migrations' => env('MIGRATION_SQUASH_BACKUP', true),

    // Backup directory path
    'backup_path' => env('MIGRATION_SQUASH_BACKUP_PATH', 'migrations/backup'),

    // Tables to exclude from schema dump
    'excluded_tables' => [
        'migrations',
    ],

    // Delete migration records from database
    'delete_batch_records' => false,
];

📊 Before & After Example

Before Squashing

database/migrations/
├── 2022_01_15_100000_create_users_table.php
├── 2022_01_15_100001_create_password_resets_table.php
├── 2022_02_20_140000_create_posts_table.php
├── 2022_02_20_140001_add_slug_to_posts_table.php
... (96 more old files)
├── 2024_10_15_140000_add_thumbnail_to_posts_table.php
├── 2024_10_20_150000_create_notifications_table.php
├── 2024_10_25_160000_add_verified_at_to_users_table.php

Total: 100 migration files 😰

After Squashing

database/migrations/
├── 0000_00_00_000000_schema_dump.php          ⭐ (Entire schema in ONE file)
├── 2024_10_15_add_thumbnail_to_posts.php      (Recent - Kept)
├── 2024_10_20_create_notifications.php        (Recent - Kept)
├── 2024_10_25_add_verified_at_to_users.php    (Recent - Kept)

Total: 4 migration files 🎉

🎯 When to Use This Package

✅ Perfect For:

• Long-running projects (1+ years old with 50+ migrations)
• Performance optimization (speed up migrate:fresh by 90%)
• Team onboarding (new developers see clean migration history)
• CI/CD pipelines (faster test suite execution)
• Before major releases (clean slate for v2.0)

❌ Not Recommended For:

• New projects (< 6 months old with few migrations)
• Active feature branches (wait until merged to avoid conflicts)
• Projects that never run migrate:fresh

🔧 How It Works

1. Analyzes all migrations in your project
2. Identifies migrations older than specified date
3. Keeps the most recent N migrations separate
4. Generates a schema dump from your current database structure
5. Creates backup of squashed migrations (optional)
6. Deletes old migration files
7. Updates migrations table (optional)

Important Notes

• ✅ Your database stays exactly the same - no data is modified
• ✅ Only migration files are affected
• ✅ Always creates backups before deletion (unless disabled)
• ✅ Safe to run - uses dry-run mode first

🧪 Testing

composer test
