rethink-migrate

A migration tool for rethink db

Version 1.2

Breaking change: In order to support rethinkdbdash, the format of the migrations has been changed from exports.up = function (connection) { and exports.down = function (connection) { to exports.up = function (r, connection) { and exports.down = function (r, connection) {

Install

npm install -g rethink-migrate

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

rethink-migrate create [migration name]

For example: rethink-migrate 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

rethink-migrate up will run all outstanding up migrations.

rethink-migrate down will run one down migration.

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

Options

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

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

Run tests

In order to run the tests, you must have a rethinkdb instance running. You can either start it locally in you machine or use the docker-compose up command to start a dockerized version of rethinkdb. In any case, you must set the IP of your running rethinkdb instance as the host address in the file test/database.json before running tests

Use npm test to actually run the test suite.

To run tests continually, use gulp test watch
