Prerequisites

You need to have a bot created and registered using the Microsoft Bot Framework and registered to use the DirectLine Channel, which will give you the secret needed when adding this web part to the page. For more information on creating a bot and registering the channel you can see the official web site at dev.botframework.com, as well as various tutorials over at www.garypretty.co.uk/category/microsoft-bot-framework/ & Stephan Bisser's blog

See more details on how to create a bot from following locations.

Notice that you can find simplistic bot implemented with Visual Studio 2015 using the bot templates (Oct 2016) under the vs2015-bot-application folder. This is simplistic bot based on above blog posts, which responses random string back.

Minimal Path to Awesome

Clone this repository
in the command line run:
- npm install
- tsd install
- gulp serve
Register your bot in the Microsoft Bot Framework Portal, configure the DirectLine channel on the bot and obtain your DirectLine secret.

Features

This Web Part illustrates the following concepts on top of the SharePoint Framework:

Connecting and communicating with a bot built on the Microsoft Bot Framework using the DirectLine Channel
Validating Property Pane Settings
Office UI Fabric
React

When adding the web part to a page you need to obtain your bot's DirectLine channel secret via the Azure Portal. You then add this secret via the Property Pane of the web part. If there is an error initializing the DirectLine Client with the bot then they will be shown in the console within the browser.

You can add DirectLine channel to bot from the bot details page under the "Add a featured channel" section

After this, you can click Edit for the just added Channel to get the needed secret for the client side web part.

Additional settings can be set to style the web part, including:

Version	Description
v3 & v4	Foreground / background colors for messages & sendbox, both from the user and from the bot
v4	Add avatar images or initials for both user and bot
v4	Hide upload button in sendbox
v3	Display title of the web part
v3	Web part header background color
v3	Placeholder text

Currently the Bot Framework Webchat v3 web part only supports plain text conversations with a bot. Other message types, such as Rich Cards and Attachments are not supported, so in order to use that, use the Bot Framework Webchat v4 web part
