Voltron-Migrator is a tool for executing SQL migrations with Node. While it's part of the Voltron.io framework, it's also a stand-alone component. Voltron-Migrator is heavily modeled after voodootikigod's migrator; in fact, the project started as a fork of voodootikigod's code.
Voltron-Migrator has two main purposes: generate SQL migrations, and execute them.
V-M allows both the application and reversion of migrations. Like Rails,
it creates a
schema_migrations table in your database to track which
migrations have already been executed, and it prefixes generated
migration files with a timestamp of 'YYYYMMDDHHMMSS'.
Migrations are written in SQL and do not use an abstraction layer.
Include Voltron.io or Voltron-Migration in your package.json file. If you
node_modules\.bin in your path, just execute
migrate. You can
provide database configuration in two ways:
via a configuration file that will be required. The config file must return an object with a
databaseproperty, which itself exposes a hash of the following properties: name, host, port, type, user (optional), password (optional).
via explicit values on the command line. The following properties are required: name, host, port, type. User and password are optional.
V-M assumes that your migrations are included in
.\migrations, but you
can change that via a CLI argument.
migrate on its own will execute migrations in order in the specified
source directory, skipping over migrations that have already been run. If
--revert as an argument, the migrations were be rolled back,
starting with the most recent migration and ignoring any migrations that
haven't yet been applied.
migrate -g or
<filename> will create two
migration files of the specified filename:
<filename>_down.sql. As you can expect,
up files are run when migrations
are executed, and
down files are run when migrations are reverted.
Postgres is currently supported.
- Add test coverage
- Implement MySQL
- Allow reversion by datestamp
In order to run the tests, you'll need to setup a database for Postgres
migrator_test). See the config files in
test/fixtures for details.
