milkshake v0.2.1

Milkshake

Simple database migration tool inspired by migrate and the rails migration tool.

• Migration scripts are stored in a folder, with a timestamp + ID + name identifier and are written in pure JS
• By default it stores which migrations have been run on the filesystem, but you can easily extend and change that behavior.
• You can have setup and teardown scripts run before and after migrations
• It will attempt to fail gracefully by saving which migrations have been run each time one has been run, and not all-or-nothing.

Usage

Install using:

npm install milkshake

To setup a new migration folder:

milkshake setup

This will create an empty folder in your current working directory named migrations and include a setup.js file by default. (Hint: Look in lib/default-setup.js to see the methods you can override in your own setup file, eg. for inserting active migrations or removing from your own database).

Create a new migration file:

milkshake new "Create table users"

This will generate a new empty migration file named <timestamp>-Create_table_users.js in the migrations folder.

To run the migration:

milkshake migrate

To see the full command line options:

milkshake --help

TODO:

• Write unit tests
• There might be some error cases we could handle better.
• Commands for listing migrations that haven't been run
