Mixin for migrate
CLI that will persist current migration state to a MongoDB collection instead of a flat file.
This is useful when you have several transient application servers (and filesystems) sharing a single database. You only need to migrate once per database; not once per filesystem.
This makes migrate
behave more like Django South or Ruby on Rails ActiveRecord Migrations.
Usage
Make sure you're using a branch of migrate that supports mixins.
npm install --save-dev git://github.com/gobengo/node-migrate#012015_mixins
.Create a new module like
tools/store-migration-state-in-mongo.js
. Something like:var mongoDbConnectionString = 'localhost'; // or get from your config file var migrationStateCollectionname = 'migration_state'; // or whatever module.exports = require('migrate-mongo-persistence')( mongoDbConnectionString, migrationStateCollectionname);
When running the migrate cli, use your mixin like
./node_modules/.bin/migrate --use tools/store-migration-state-in-mongo.js <migrateCommand>
