Dbsnap NPM | npm.io

Db snap

Database versioning tool. Used to take snapshots of your database tables (and optionally data) and then restore any of the snapshots later. It works by saving the state of your database in files then later using those files to restore the same state. Although this tool is fully capable of tracking your database changes and snapshots, you may choose to also commit the tracking files in git.

Installation

> npm install -g dbsnap

Example Usage

Go to your project folder or where you would like the snapshots to be saved

First setup database credentials (note: this is done only once per project )
> dbsnap set --username myuser --password 12345 --dbname mydb

Take a snapshot of database and save it as v1.0.0
> dbsnap take v1.0.0

Make changes to database
Then restore database to snapshot that was saved as v1.0.0
> dbsnap restore v1.0.0

To see a list of saved snapshots
> dbsnap list

To delete a snapshot named v1.0.1
> dbsnap delete v1.0.1

To snapshot only a specific table (e.g. users table) and save the snapshot as users-v1.0.0
> dbsnap take users-v1.0.0 --tables users

To snapshot only a specific set of tables (e.g. user-carts, cart-items, and products tables) and save the snapshot as cart-tables-v1.0.0
> dbsnap take cart-tables-v1.0.0 --tables "user-carts, cart-items, products"

Including data

To snapshot all tables (including data) and save the snapshot as mydb-v1.0.0
> dbsnap take mydb-v1.0.0 --all

To snapshot all tables but include data for only some of them (e.g.roles table) and save the snapshot as mydb-v1.0.0
> dbsnap take mydb-v1.0.0 --data roles
Or if more than one e.g. (roles and permissions tables)
> dbsnap take mydb-v1.0.0 --data "roles, permissions"

To snapshot only a specific table (including data) and save the snapshot as users-v1.0.0
> dbsnap take users-v1.0.0 --tables users --data users

To snapshot only a specific set of tables (including data) and save the snapshot as cart-tables-v1.0.0
> dbsnap take cart-tables-v1.0.0 --tables "user-carts, cart-items, products" --with-data

Other options

To list all commands, please use
> dbsnap help
OR
> dbsnap help <command-name> to list all options for a command

Notes

When setting up credentials you can also specify --dbhost and --port
dbsnap saves snapshots in a subfolder named .dbsnap add this to git if you want to track with git
Database credentials are stored in a file named .dbsnap.json, make sure to add it to .gitignore to avoid sharing credentials
Currently this only works for mysql databases
If you snapshot only a specific table or set of tables, the restore operation will not touch the other tables.
If you make a full snapshot (i.e. no --tables options during take operation) you can restrict the tables to touch during a restore operation by using the --tables option (e.g. > dbsnap restore v2.5.0 --tables "users, products")
For restore operations, --data works in a similar fashion to --tables i.e. it is not required when restoring tables. By default snapshots that include data will restore that data as well. However, you can restrict which data to restore by using the --data option (e.g. > dbsnap restore v2.5.0 --data "roles, permissions" will restore all the tables but will only restore data for roles and permissions tables)
