node-mysql2-migrations

A tool to support migration using the mysql 2 package in node.js

Prerequisites

A node project with mysql2 used for database.

Install

It can be installed using npm.

npm i mysql2-migration

Setup

1. Create a file in config directory where you define your database config. (./config/database.js)

database.js:

module.exports = {
    host: 'localhost', // optional
    port: '3306', // optional
    user: 'user',
    database: 'database',
    password: 'password'
}

2. In the root of your project, create a file with the package connection. (Should be on one level with node_modules)

migration.js:

require('mysql2-migrations')

Create a migration

Run

node migration.js create create_users_table
node migration.js create update_users_table
node migration.js create drop_users_table
node migration.js create add_age_column_to_users_table 
node migration.js create add_age_column_to_users_table string
node migration.js create change_age_column_users_table
node migration.js create change_age_column_users_table integer
node migration.js create drop_age_column_from_users_table
node migration.js create drop_age_column_from_users_table tnteger

After that, you can find your migration in ./database/migrations.
