    DATA ELEVATOR MYSQL

    The data elevator mysql is an easy to use and very flexible utility for migrating data sources based on the NPM module data elevator. The only difference is that data elevator mysql stores its current migration level in a mysql database.

    Storing the current migration level in a database brings advantages when a project shares its data source with multiple running instances of a project. For example when multiple developers working with one database or the project runs on multiple servers.

    QUICKSTART

    STEP 1: Install

    npm install data-elevator-mysql
    

    STEP 2: Construct a new data elevator for the project.

    node ./node-modules/data-elevator-mysql construct
    

    STEP 3: Add a new migration.

    node ./data-elevator/elevator add "add phone number to users"
    

    STEP 4: Enter you migration code in the generated floor file.

    see: ./data-elevator/floors/
    

    STEP 5: Move the elevator to migrate data.

    node ./data-elevator/elevator move top
    node ./data-elevator/elevator move ground
    node ./data-elevator/elevator move 2
    

    STEP 6: Use help command to get information about additional commands

    node ./data-elevator/elevator help
