Bot Framework SDK for JavaScript v4.6.0-preview2

Welcome to the 4.6.0-preview2 release of the Bot Framework SDK for JavaScript available via MyGet!

This is a preview release for streaming support in the Bot Framework SDKs for JavaScript.

Changes:

Breaking Changes:

• botframework-streaming-extensions and botbuilder-streaming-extensions have been delisted from MyGet
  • botbuilder contains the updated BotFrameworkAdapter class which is used to interpret incoming streaming requests (formerly botbuilder-streaming-extensions and BotFrameworkStreamingAdapter)
  • botframework-streaming now contains the Request and Transport layer specific code (formerly botframework-streaming-extensions)

Changes:

• Developers must set enableWebSockets to true in BotFrameworkAdapterSettings to enable WebSockets
• BotFrameworkAdapter now uses a Factory pattern for more extensibility when using WebSockets
  • Developers can pass in an instance of a NodeWebSocketFactoryBase to the BotFrameworkAdapter via BotFrameworkAdapterSettings.webSocketFactory
  • If enableWebSockets is true and no factory is passed in, the BotFrameworkAdapter will default to a NodeWebSocketFactory
• BotFrameworkAdapter.useWebSocket() and BotFrameworkAdapter.useNamedPipe() are now public
• Fixed filename casing issues
• Minor cleanup and bug fixes

---

Samples:

For an example of how to configure your bot to use WebSockets and Direct Line Speech, please visit the botbuilder-samples repository. Navigate to the /experimental/directline-speech/javascript_nodejs/02.echo-bot sample which was updated via this commit: microsoft/BotBuilder-Samples@651f405

Here is a modified snippet from the sample which shows how to set configure a bot to use WebSockets:

// Create HTTP server and configure the Server to handle for Upgrade requests.
const server = restify.createServer({ handleUpgrades: true });
server.listen(process.env.port || process.env.PORT || 3978);

// BotFrameworkAdapterSettings configuration object.
const adapterSettings = {
    appId: process.env.MicrosoftAppId,
    appPassword: process.env.MicrosoftAppPassword
};

const myBot = new EchoBot();

// Listen for GET requests to the same route to accept Upgrade requests for Streaming.
server.get('/api/messages', (req, res) => {
    // Create an adapter scoped to this WebSocket connection to allow storing session data.
    // Get the appId and appPassword from the above settings object and set enableWebSockets to true.
    const streamingAdapter = new BotFrameworkAdapter({
        ...adapterSettings,
        enableWebSockets: true
    });
    // Set onTurnError for the BotFrameworkAdapter created for each connection.
    streamingAdapter.onTurnError = onTurnErrorHandler;

    streamingAdapter.processActivity(req, res, async (context) => {
        // After connecting via WebSocket, run this logic for every request sent over
        // the WebSocket connection.
        await myBot.run(context);
    });
});

Bot Framework SDK for Javascript v4.6

v4.6.0

Welcome to the 4.6 release of the Bot Framework SDK for JavaScript!

Bot Framework SDK for Microsoft Teams (GA)

The Bot Framework SDK v4.6 release fully integrates support for building Teams bots allowing users to use them in channel or group chat conversations. By adding a bot to a team or chat, all users of the conversation can take advantage of the bot functionality right in the conversation.

Adaptive Dialog (Preview)

Adaptive Dialogs enable developers to build conversations that can be dynamically changed as the conversation progresses. It allows developers to dynamically update conversation flow based on context and events. This is especially handy when dealing with conversation context switches and interruptions in the middle of a conversation.

Language Generation (Preview)

Language Generation enables developers to separate logic used to generate bot's respones including ability to define multiple variations on a phrase, execute simple expressions based on context, refer to conversational memory.

Common Expression Language (Preview)

Common Expression Language allows you to evaluate the outcome of a condition-based logic at runtime information. We provide a common language that can be used across the Bot Framework SDK and conversational AI components, such as Adaptive Dialogs and Language Generation.

The issues list can be viewed here.

Bot Framework SDK for Javascript v4.5

v4.5.0

Welcome to the 4.5 release of the Bot Framework SDK for Javascript!

Today, we are happy to announce the Bot Framework support for Emulator Channel Testing is generally available. This enables developers to debug and test your Bot Framework SDK v4 bots on channels like Microsoft Teams, Slack, Cortana, Facebook Messenger, Skype, etc. As you have the conversation, messages will be mirrored to the Bot Framework Emulator where you can inspect the message data that the bot received. Additionally, a snapshot of the bot state for any given turn between the channel and the bot is rendered as well.

We also added capabilities for Unit Testing your bots. The Microsoft.Bot.Builder.Testing package simplifies the process of unit testing dialogs in your bot.

As with any release, we fixed a number of bugs, continue to improve LUIS and QnA integration and further clean our engineering practices. There were additional updates across other areas like Language, Prompts, Dialogs, State and Storage.
