mygrate

Database migrations for MySQL and PostgreSQL database.

This utility uses SQL files for migrations that, if need be, can be run by mysql or psql command line utilities. It does not try to be cute.

Installation

npm install -g mygrate

Depending on your database, you will need to install either

npm install mysql

npm install pg

Running

To create migrations directory and config.js sample which must be edited for your database.

mygrate init

To create a migration script.

mygrate gen add-tables

That command creates migration/TIMESTAMP-add-tables/{down,up}.sql. Edit these scripts as needed.

To run migrations, do any of the following

mygrate up                           # migrate all scripts
mygrate down                         # down 1 migration
mygrate down 2                       # down 2 migrations
mygrate down all                     # down all migrations
mygrate down TIMESTAMP-some-script   # down to migration before this one

To view migrations applied to the database
