mongoose-data-migrate

Mongodb data migration tool using node.js and mongoose. Heavily inspired by madhums/mongoose-migrate.

At a high level, here's how you use it:

1. run 'mongoose-data-migrate create my-migration1' to create your migration files. The files are created in the _migrations_ folder in the root of your project.
2. implement the up and down methods in each migration file.
3. running 'mongoose-data-migrate up' will run all migration files that are in the _migrations_ folder that have not yet been run.
4. running 'mongoose-data-migrate down' will execute the _down_ method on all migration to the point that the previous 'migrate up' was run.

Installation

$ npm install -g mongoose-data-migrate

Usage

``
Usage: mongoose-data-migrate [up|down|create]

Commands:

up run all new migrations since the previous run
down migrate down to the point of the previous migrate up
create [title] create a new migration file with optional [title]
`

Config file

`
module.exports = {

// The location of the the mongoose module. Since mongoose-data-migrate
// needs to make a connection to mongodb, if you point to it here you'll
// be able to use the same connection in your migration files rather than
// creating your own connection.
mongoose: '../node_modules/mongoose',

// mongodb connection string in mongoose format: 'mongodb://username:password@host:port/database?options...'
// See: http://mongoosejs.com/docs/connections.html
db: 'mongodb://localhost:27017',

// Name for the migrations collection (defaults to 'migrations')
collection: 'migrations'
};
`

Mongoose Compatability

So far mongoose-data-migrate has only been tested with Mongoose 3.8.x.

Testing

1. an instance of mongodb running at localhost:27017.
2. a db named 'mongoose_data_migrate_test' without any credentials

To run the tests:

`
npm test
