Bot Framework v4 echobot with counter sample
This sample shows how to create a simple bot with state. The bot maintains a simple counter that increases with each message from the user.
- [Node.js][4] version 8.5 or higher
# determine node version
node --version
- Clone the repository
git clone https://github.com/microsoft/botbuilder-samples.git
- In a terminal, navigate to
samples/javascript_nodejs/02.b.echobot-with-counter
cd samples/javascript_nodejs/02.b.echobot-with-counter
- Install modules
npm install
- Start the bot
npm start
Microsoft Bot Framework Emulator is a desktop application that allows bot developers to test and debug their bots on localhost or running remotely through a tunnel.
- Install the Bot Framework emulator from here
- Launch Bot Framework Emulator
- File -> Open Bot Configuration and navigate to
samples/javascript_nodejs/02.echobot-with-state
folder - Select

A key to good bot design is to track the context of a conversation, so that your bot remembers things like the answers to previous questions. Depending on what your bot is used for, you may even need to keep track of conversation state or store user related information for longer than the lifetime of one given conversation.
In this example, the bot's state is used to track number of messages.
A bot's state is information it remembers in order to respond appropriately to incoming messages. The Bot Builder SDK provides classes for storing and retrieving state data as an object associated with a user or a conversation.
- Conversation properties help your bot keep track of the current conversation the bot is having with the user. If your bot needs to complete a sequence of steps or switch between conversation topics, you can use conversation properties to manage steps in a sequence or track the current topic. Since conversation properties reflect the state of the current conversation, you typically clear them at the end of a session, when the bot receives an end of conversation activity.
- User properties can be used for many purposes, such as determining where the user's prior conversation left off or simply greeting a returning user by name. If you store a user's preferences, you can use that information to customize the conversation the next time you chat. For example, you might alert the user to a news article about a topic that interests her, or alert a user when an appointment becomes available. You should clear them if the bot receives a delete user data activity.
You can use the MSBot Bot Builder CLI tool to clone and configure any services this sample depends on. Ensure you have Node.js version 8.5 or higher.
