East-rethink NPM

east rethink

rethinkdb adapter for east (node.js database migration tool) which uses pensuer

All executed migrations names will be stored at migrations table in the current database. Object with following properties will be passed to migrate and rollback functions:

db - instance of pensuer

Installation

npm install east east-rethink -g

alternatively you could install it locally

Usage

go to project dir and run

east init

create .eastrc file at current directory

{
    "adapter": "east-rethink",
    "tables": ["card", "group", "user"],
    "database": {
        "name": "mydatabase",
        "migrationTable": "mymigrationtable",
        "connection": {
            "host": "localhost",
            "port": 28015
        }
    }
}

where

tables is an array of the tables you wish to connect to in your database.
database is a json object with the following properties: name - database name, migrationTable - migration table name (optional - defaults to 'migration'), connection - a json object with host and port providing the host name and port number for your database respectively.

now we can create some migrations

east create apples
east create bananas

created files will looks like this one

exports.migrate = function(client, done) {
    var db = client.db;
    done();
};

exports.rollback = function(client, done) {
    var db = client.db;
    done();
};

edit created files and insert

to 1_apples

exports.migrate = function(client, done) {
    var db = client.db;

    db.card.insert( { id: 'red-apple', type: 'apple', color: 'red' })
        .then(() => done(null), done);
};

exports.rollback = function(client, done) {
    var db = client.db;

    db.card.remove({ id: 1 })
        .then(() => done(null), done);
};

to 2_bananas

exports.migrate = function(client, done) {
    var db = client.db;
    db.card.insert( { id: 2, type: 'banana', color: 'yellow' })
        .then(() => done(null), done);
};

exports.rollback = function(client, done) {
    var db = client.db;
    db.card.remove({ id: 2 }, (err) => {

        if (err) return done(err);

        return done(null);
    });
};

now we can execute our migrations

east migrate

output

target migrations:
    1_apples
    2_bananas
migrate `1_apples`
migration done
migrate `2_bananas`
migration done

and roll them back

east rollback

output

target migrations:
    2_bananas
    1_apples
rollback `2_bananas`
migration successfully rolled back
rollback `1_apples`
migration successfully rolled back

you can specify one or several particular migrations for migrate/rollback e.g.
