Installation

Install globally via npm:

npm install -g db-migrate-cli

This makes the db-cli command available system-wide.

Usage

🚀 Quick Start

Get up and running with db-migrate-cli in just a few simple steps! Here's how you can manage your database migrations like a pro.

1. Setup Your Migration Configuration

db-cli setup

• 📝 Creates database/config.js.
• 🔧 Customize migrationDir and database settings in this file.

Example:

db-cli setup

# Output:
# Configuration file created at database/config.js

2. Initialize Migration Infrastructure

db-cli migrate:init

• ⚙️ Creates db_migrations table and necessary stored procedures in your database.

Example:

db-cli migrate:init

# Output:
# Migration infrastructure initialized. 'db_migrations' table created.
# Procedures 'db_cli_add_migration', 'db_cli_delete_migration', 'db_cli_get_last_batch_migrations', and 'db_cli_get_migrations' created.

3. Create Your First Migration

db-cli make:migration <migration_name>

• 📁 Creates a migration file in migrationDir with a timestamp and name in snake case.

Example:

db-cli make:migration create_users_table

# Output:
# Migration file created: 2024_08_09_13_59_01_create_users_table.sql

4. Apply Migrations

db-cli migrate

• ✅ Executes all pending migrations.

Example:

db-cli migrate

# Output (Single SQL Statement in `-- UP`):
# Migrating: 2024_08_09_13_59_01_create_users_table.sql
# Migrated: 2024_08_09_13_59_01_create_users_table.sql

# Output (Multiple SQL Statements in `-- UP`)
# Migrating: 2025_04_04_06_16_45_create_common_crud_procedures.sql
# Statement 1/4 lines  4–20: CREATE PROCEDURE insert_record_into_table(
# Statement 2/4 lines 22–37: CREATE PROCEDURE update_table_record(
# Statement 3/4 lines 39–53: CREATE PROCEDURE delete_record_from_table(
# Statement 4/4 lines 55–71: CREATE PROCEDURE select_records_from_table(
# Migrated: 2025_04_04_06_16_45_create_common_crud_procedures.sql

5. Rollback Changes

db-cli rollback

• ⏪ Reverts the most recent batch of migrations.

Example:

db-cli rollback

# Output (Single SQL Statement in `-- DOWN`):
# Rolling back: 2024_08_09_13_59_01_create_users_table.sql
# Rolled back: 2024_08_09_13_59_01_create_users_table.sql

# Output (Multiple SQL Statements in `-- DOWN`):
# Rolling back: 2025_04_04_06_16_45_create_common_crud_procedures.sql
# Statement 1/4  line  77: DROP PROCEDURE IF EXISTS insert_record_into_table
# Statement 2/4  line  78: DROP PROCEDURE IF EXISTS update_table_record
# Statement 3/4  line  79: DROP PROCEDURE IF EXISTS delete_record_from_table
# Statement 4/4  line  80: DROP PROCEDURE IF EXISTS select_records_from_table
# Rolled back: 2025_04_04_06_16_45_create_common_crud_procedures.sql

6. Reset Migrations

db-cli  reset

• 🔄 Rolls back all applied migrations in reverse order.
• Does not reapply them — use it to clean your database of all applied migrations.

Example:

db-cli  reset

# Output (Single SQL Statement in `-- DOWN`):
# Rolling back: 2024_08_09_13_59_01_create_users_table.sql
# Rolled back: 2024_08_09_13_59_01_create_users_table.sql
# ...
# All migrations have been reset.

# Output (Multiple SQL Statements in `-- DOWN`):
# Rolling back: 2025_04_04_06_16_45_create_common_crud_procedures.sql
# Statement 1/4 line 77: DROP PROCEDURE IF EXISTS insert_record_into_table
# Statement 2/4 line 78: DROP PROCEDURE IF EXISTS update_table_record
# Statement 3/4 line 79: DROP PROCEDURE IF EXISTS delete_record_from_table
# Statement 4/4 line 80: DROP PROCEDURE IF EXISTS select_records_from_table
# Rolled back: 2025_04_04_06_16_45_create_common_crud_procedures.sql
# ...
# All migrations have been reset.

📁 Project Structure

After setup and creating migrations, your project structure may look like:

project-root/
├──  database/
│  ├──  config.js  # Configuration file for DB connection and migration settings
│  ├──  migrations/  # Folder containing SQL migration files
│  │  └──  2024_08_09_13_59_01_create_users_table.sql  # Example migration file

SQL-Based Migrations

db-migrate-cli uses SQL files for migrations, with -- UP for applying changes and -- DOWN for rolling back. This gives you full control over the SQL executed.

Anatomy of a Migration File:

-- migrations/2024_08_09_13_59_01_create_users_table.sql

-- UP
CREATE TABLE users (
    id INT AUTO_INCREMENT PRIMARY KEY,
    name VARCHAR(255) NOT NULL,
    age INT
);

-- DOWN
DROP TABLE users;

Each migration file is written in SQL and includes two sections:

• -- UP: SQL commands to apply the changes (e.g., creating tables, adding columns).
• -- DOWN: SQL commands to reverse the changes (e.g., dropping tables, removing columns).

Advanced Features

• ✅ Multiple statements under -- UP and -- DOWN are supported.
• 🔄 Handles custom delimiters like DELIMITER $$, perfect for stored procedures and complex routines.
• 🧠 Smart parsing to preserve block contents inside BEGIN ... END or CREATE PROCEDURE.
• 🔢 Tracks executed statements by line number, enabling precise rollbacks.

Example: Migration with Delimiters

-- UP
DELIMITER $$

CREATE PROCEDURE sp_log_error(
    IN request_id INT,
    IN message TEXT
)
BEGIN
    INSERT INTO error_logs (request_id, message, created_at)
    VALUES (request_id, message, NOW());
END$$

DELIMITER ;

-- DOWN
DROP PROCEDURE IF EXISTS sp_log_error;

This ensures your stored routines are executed correctly without getting split or malformed during parsing.
