TIL Something About Bot Middleware

PREAMBLE: I am trying to blog about the little things now. The idea is partly the reason why so many technical blogs exist - it’s a place for me to record things I’ll need to recall later. But modern search engines are good enough, that you just might make it to this blog post to answer a question that’s burning a hole in your brain right now and that’s awesome. I know I love it when I get a simple, concise, and sensible explanation of something I’m trying to figure out.

MORE PRE-RAMBLE: So, I’ve sort of drifted into bot territory. That is, I didn’t initially get extremely excited about the concept of chat bots. It seemed silly. I have since been convinced of their big business value and have really enjoyed learning how to embrace the Node.js SDK for Microsoft’s Bot Framework.

Recently, I realized that the very best way to learn about the SDK is not to search online for docs or posts, but to go straight to the source, and when you get there, look specificallly for the /core/lib/botbuilder.d.ts file.

That file is a treasure trove of useful comments directly decorating the methods, interfaces, and properties of your bot. It’s great that the bot is written in TypeScript, because that means this source code contains a lot of documenting types that not only made it easier for the team to developer this, but now make it easier for us to read it as well.

Tonight I was specifically wondering about something. I had seen middleware components for bots using property values of botbuilder and send, but then I saw receive and wondered what every possible property was and specifically what they did.

I discovered that in fact botbuilder, send, and receive are the only possible property values there. Let me drop that snippet of the source code here, so you can see how well documented those are…

/**
* Map of middleware hooks that can be registered in a call to __UniversalCallBot.use()__.
*/
interface IMiddlewareMap {
/** Called in series when an incoming event is received. */
receive?: IEventMiddleware|IEventMiddleware[];
/** Called in series before an outgoing event is sent. */
send?: IEventMiddleware|IEventMiddleware[];
/** Called in series once an incoming message has been bound to a session. Executed after [analyze](#analyze) middleware. */
botbuilder?: ICallSessionMiddleware|ICallSessionMiddleware[];
}

The IMiddlewareMap is an interface, which is a TypeScript concept. That’s not in raw JavaScript. TypeScript does interfaces right, because they’re not actually enforced on objects that implements them (we are, afterall, talking about JavaScript where pretty much nothing is enforced). Rahter, they’re an indication of intent - as in “I intend for my object to conform to the IMiddlewareMap interface.”

That means that at design time (when you’re typing the code in your IDE), you get good information back about whether what you’re typing lines up with what you said this object is expected to be.

So that’s just one little thing I learned tonight wrapped up with all kinds of preamble, pre-ramble, and other words. Hope it helps. Happy hacking.

Developer Reactions to Build 2016

Microsoft takes opportunity every year at //build - its annual conference for developers - to make as many shock and awe announcements as it can, and this year in 2016, there was plenty of shock and plenty of awe.

Maybe you’ve watched all the keynotes already. Maybe you’ve even watched all of the sessions already. We’re going to assume, however, that even if you have seen or otherwise caught wind of the announcements that you would like to get an answer to the question “What does that mean for me?”
In this post, I’m going to invite a number of colleagues - all Microsoft Technical Evangelists - to share in detail via blog posts and videos about their favorite announcements, and what they mean for you - the developer.

This is an active blog post that will be updated as new content lands, so check back often.

We’ll start with a Channel 9 introduction to a few of the team. In this video you’ll meet…

Now, as promised, here’s the line-up of content from the evangelists you saw in the video and a few more. Topics will be filled in as we go and links will light up when they’re active.
