migrate-rethinkdb

A migration tool for RethinkDB

Forked from ParabolInc/migrate-rethinkdb

Overview

migrate-rethinkdb is a utility allowing you to version changes to a RethinkDB database. Forward or backward migrate structural or data changes. Share and control these changes with other developers.

This code is a fork of Johan Obrink's rethink-migrate. migrate-rethinkdb is more actively maintained.

Install

$ npm install -g migrate-rethinkdb

Setup

Install a RethinkDB driver:

npm install --save rethinkdb

or

npm install --save rethinkdbdash

Create a database.json file in the root of your solution with the format:

{
  "host": "localhost",
  "port": 28015,
  "db": "migrations",
  "discovery": true,
  "timeout": 60
}

Other, optional, parameters are authKey and ssl.

You can also use environment variables or arguments to override.

Log levels

The default is info. This will log info, warnings and errors. Possible values for logLevel are "debug" | "info" | "warning" | "error" | "none".

Create migration

$ migrate-rethinkdb create [migration name]

For example:

migrate-rethinkdb create add-tables

Edit migration

Open the file ./migrations/[timestamp]-[migration name].js

Add the changes to be made. For example:

exports.up = function (r, connection) {
  return r.tableCreate('foo').run(connection);
};

exports.down = function (r, connection) {
  return r.tableDrop('foo').run(connection);
};

Run migrations

migrate-rethinkdb up --one will run one up migration.

migrate-rethinkdb up --all will run all outstanding up migrations.

migrate-rethinkdb down --one will run one down migration.

migrate-rethinkdb down --all will run all outstanding down migrations.

If either --all or --one isn't specified, --all is the default.

Options

migrate-rethinkdb up --root ./build will run all outstanding up migrations found in ./build/migrations with database.json in ./build. -r can be used as an alias.

migrate-rethinkdb up --logLevel debug will set logLevel to debug. Possible values are: debug | info | warning | error | none. -l can be used as an alias.

migrate-rethinkdb up --loadEnv will load .env file to environmental variable. -le can be used as an alias.

Run tests

Run docker-compose up If necessary, change the IP address in test/database.json Run gulp jshint test

To run tests continually, add watch to the gulp command
