MyVC (MySQL Version Control)

Utilities to ease the maintenance of MySQL or MariaDB database versioning using a Git repository.

This project is just to bring an idea to life and is still in an early stage of development, so it may not be fully functional.

Any help is welcomed! Feel free to contribute.

Prerequisites

Required applications.

Node.js = 12.17.0 LTS
Git
Docker

Installation

It's recommended to install the package globally.

# npm install -g myvc
$ myvc [command]

You can also install locally and use the npx command to execute it.

$ npm install myvc
$ npx myvc [command]

How to use

Execute myvc with the desired command.

$ myvc [-w|--workspace] [-e|--env] [-h|--help] command

The default working directory is the current one and unless otherwise indicated, the default environment is production.

Available commands are:

pull: Exports database routines into workspace.
push: Apply changes into database, uses test environment by default.
dump: Export database structure and fixtures.
run: Builds and starts local database server container.
start: Starts local database server container.

Each command can have its own specific commandline options.

Basic information

First of all you have to import structure.sql into your database. This script includes the tables where MyVC stores information about applied versions.

Create myvc.config.json main configuration file at the root of your project folder, this file should include the project codename and schemas/tables wich are exported when you use pullor dump commands. You have an example of a configuration file in the root folder of this project.

Environments

Create database connection configuration files for each environment at main project folder using standard MySQL .ini. The predefined environment names are production and testing.

db.[environment].ini

Dumps

Structure and fixture dumps will be created into hidden file .dump.sql. You can also create your local fixture and structure files.

myvc.structure.sql
myvc.fixtures.sql

Routines

Routines should be placed inside routines folder. All objects that have PL/SQL code are considered routines. It includes events, functions, procedures, triggers and views with the following structure.

  routines
  `- schema
     |- events
     |  `- eventName.sql
     |- functions
     |  `- functionName.sql
     |- procedures
     |  `- procedureName.sql
     |- triggers
     |  `- triggerName.sql
     `- views
        `- viewName.sql

Versions

Versions should be placed inside changes folder with the following structure.

  changes
  |- 00001-firstVersionCodeName
  |  |- 00-firstExecutedScript.sql
  |  |- 01-secondScript.sql
  |  `- 99-lastScript.sql
  `- 00002-secondVersion
     |- 00-firstExecutedScript.sql
     `- 00-sameNumbers.sql
