mongo-migra v1.8.0

Mongo Migra

This small library works as friendly migration tool for mongodb databases. Supports replicas and transactions.

How it works

We use mongodb connector in order to create/delete/execute migrations scripts on mongodb databases. Each script receives the mongodb client and a session only when replicaSet is setup in order to support transactional operations.

Inspiration

We don't have a simple tool to migrate mongodb databases and this one keeps everything simple, we don't use anything else rather than the mongo connector.

How to install

npm i --save-dev mongo-migra or globally npm i -g mongo-migra

Once installed you can execute the command as a terminal command.

How to use it
