Persistence Bundle for Botyo

The Persistence Bundle for Botyo consists of a few components related to the persistence of messages in a MongoDB database.

The included components are:

• MongoDbConnector - An AsyncResolvable that connects to a MongoDB server during the initialization of Botyo and provides access to the database via the Db object provided by the MongoDB Node.JS Driver.
• MessageDownloaderFilter - Filter that saves each incoming message to the database.
• ChatThreadHistoryDownloaderScheduledTask - Scheduled task that downloads the history of all chat threads Botyo is configured to listen to and saves it to database.

Step 1. Install the module from npm.

npm install --save botyo-bundle-persistence

Step 2. Configure the MongoDB connection.

Add the Connection String URL to your configuration file config.yaml:
