An experimental rule system handy for intepreting user input, great for adding conversational features to apps, using lessons learned from the message router pattern. I thought of it as I walked around Prague on a sunny Spring day. This is just an experiment and not an official Microsoft project.

Major features of Prague:

• strongly-typed rules engine for interpreting ambiguous input of all kinds
• support for different types of applications through fine-grained interfaces rather than high-level abstraction
• deeply asynchronous via RxJS

Some types of applications you could build with Prague:

• OS shell
• Browser app w/chat interface
• Browser app w/voice interface
• Slack bot (native interface)
• Multi-platform Chat bot
• Server-rendered Website w/pop-up chat

• clone or fork this repo
• npm install
• npm run build (or npm run watch to build on file changes)

Prague is a low-level framework. If you want to build an app you will want to use (or create) a recipe, which is a set of functionality that allows you to exchange messages with a given channel, using a given state store, etc. Here is a list of available recipes. Please post your own!

• prague-botframework-browserbot - Build in-browser bots using the Bot Framework WebChat
• prague-nodeconsole - Build Node console bots

Prague includes an ever-growing number of samples which can be built and run by following the directions in each samples' README:

• Simple Dialog
• AlarmBot
• Scaffold (this is a great place to start experimenting with your own bot, using concepts from the tutorial and the other samples)

• Simple routing
• More on routing
• State and routing
• Dialog

• More on Dialogs
• Prompts
• Async
• Natural Language
