## What's Included

This module contains interfaces to use common Azure services to back Bot Builder's state storage.
When used with `UserState`, `ConversationState` and `BotState`, these storage interfaces will automatically
read and write values to the associated Azure service.

It currently supports Cosmos DB ([`CosmosDbStorage()`](https://docs.microsoft.com/en-us/javascript/api/botbuilder-azure/cosmosdbstorage)) and Azure Blob Storage ([`BlobStorage()`](https://docs.microsoft.com/en-us/javascript/api/botbuilder-azure/blobstorage)).

Also included is an interface to store and retrieve chat transcripts in blog storage called [AzureBlobTranscriptStore()](https://docs.microsoft.com/en-us/javascript/api/botbuilder-azure/azureblobtranscriptstore)

## Use

Import the module into your app.
```javascript
const { BlobStorage } = require('botbuilder-azure');
```

Configure the storage driver to work with your Azure resources.
```javascript
const blobStorage = new BlobStorage(options);
```

Pass the storage driver into your state managers:
```javascript
const userState = new UserState(blobStorage);
const conversationState = new ConverationState(blobStorage);
```
