webex-node-bot-framework

Node JS Bot Framework for Cisco Webex

This project is inspired by, and provides an alternate implementation of, the awesome node-flint framework by Nick Marus. The framework makes it easy to quickly develop a Webex messaging bot, abstracting away some of the complexity of Webex For Developers interfaces, such as registering for events and calling REST APIs. A bot developer can use the framework to focus primarily on how the bot will interact with users in Webex, by writing "handlers" for various message or membership events in spaces where the bot has been added.

The primary change in this implementation is that it is based on the webex-jssdk which continues to be supported as new features and functionality are added to Webex.

For developers who are familiar with flint, or who wish to port existing bots built on node-flint to the webex-node-bot-framework, this implementation is NOT backwards compatible. Please see Migrating from the original flint framework

Feel free to join the "Webex Node Bot Framework" space on Webex to ask questions and share tips on how to leverage this framework.

News

• May, 2020 - Version 2 introduces a some new configuration options designed to help developers restrict access to their bot. This can be helpful during the development phase (guideEmails parameter) or for production bots that should be restricted for use to users that have certain email domains (restrictedToEmailDomains parameter). See Membership-Rules README

• October 31, 2020 - Earlier this year, a series of blog posts were published to help developers get started building bots with the framework:

  • From zero to webex chatbot in 15 minutes
  • Introducing the Webex bot framework for node.js
  • A deeper dive into the framework
  • Five tips for well behaved bots

  For first timers, I strongly recommend following these, running the sample app, stepping through it in the debugger, and getting a sense of how the framework works. Once you have done the detailed documentation here will make a lot more sense!

Overview

The framework provides developers with some basic scaffolding to quickly get a bot up and running. Once a framework object is created with a configuration that includes a bot token, calling the framework.start() method kicks of the setup of this scaffolding. The framework registers for all Webex Teams events, and may discover existing Webex Teams spaces that the bot is already a member of.

A bot object is created for each space, and the framework generates a spawn event each time it finds a new one. When all existing bot objects are created the framework generates an initialized event signalling that it is ready to begin "listening" for user input.

// init framework
var framework = new Framework(config);
framework.start();

// An initialized event means your webhooks are all registered and the 
// framework has created bot objects for the spaces your bot was found in
framework.on("initialized", function () {
  framework.debug("Framework initialized successfully! [Press CTRL-C to quit]");
});

// A spawn event is generated when the framework finds a space with your bot in it
// You can use the bot object to send messages to that space
// The id field is the id of the framework
// If addedBy is set, it means that a user has added your bot to a new space
// Otherwise, this bot was in the space before this server instance started
framework.on('spawn', function (bot, id, addedBy) {
  if (!addedBy) {
    // don't say anything here or your bot's spaces will get 
    // spammed every time your server is restarted
    framework.debug(`Framework created an object for an existing bot in a space called: ${bot.room.title}`);
  } else {
    // addedBy is the ID of the user who just added our bot to a new space, 
    // Say hello, and tell users what you do!
    bot.say('Hi there, you can say hello to me.  Don\'t forget you need to mention me in a group space!');
  }
});

Most of the framework's functionality is based around the framework.hears() function. This defines the phrase or pattern the bot is listening for and what actions to take when that phrase or pattern is matched. The framework.hears() function gets a callback that includes three objects: the bot object, and the trigger object, and the id of the framework.

The bot object is a specific instance of the bot class associated with the Webex Teams space that triggered the framework.hears() call.
The trigger object provides details about the message that was sent, and the person who sent it, which caused the framework.hears() function to be triggered.

A simple example of a framework.hears() function setup:

framework.hears(phrase, function(bot, trigger, id) {
  bot.<command>
    .then(function(returnedValue) {
      // do something with returned value
    })
    .catch(function(err) {
      // handle errors
    });
});

• phrase : This can be either a string or a regex pattern. If a string, the string is matched against the first word in the room message. message. If a regex pattern is used, it is matched against the entire message text.
• bot : The bot object that is used to execute commands when the phrase is triggered.
• bot.<command> : The Bot method to execute.
• then : Node JS Promise keyword that invokes additional logic once the previous command is executed.
• catch : handle errors that happen at either the original command or in any of the chained 'then' functions.
• trigger : The object that describes the details around what triggered the phrase.
• commands : The commands that are ran when the phrase is heard.

Authentication

The token used to authenticate the Framework with the Webex API is passed as part of the options used when instantiating the Framework class. To change or update the token, use the Framework#setWebexToken() method.

Example:

var newToken = 'Tm90aGluZyB0byBzZWUgaGVyZS4uLiBNb3ZlIGFsb25nLi4u';

framework.setWebexToken(newToken)
.then(function(token) {
  console.log('token updated to: ' + token);
});

Storage

The storage system used in the framework is a simple key/value store and resolves around these 3 methods:

• bot.store(key, value) - Store a value to a bot instance where 'key' is a string and 'value' is a boolean, number, string, array, or object. This does not not support functions or any non serializable data. Returns the a promise with the value.
• bot.recall(key) - Recall a value by 'key' from a bot instance. Returns a resolved promise with the value or a rejected promise if not found.
• bot.forget([key]) - Forget (remove) value(s) from a bot instance where 'key' is an optional property that when defined, removes the specific key, and when undefined, removes all keys. Returns a resolved promise if deleted or not found.

When a bot is first spawned, the framework calls the bot.initStorage method which attepts to load any previously existing bot storage elements (if using a persistent storage driver such as MongoStore), or will create an optional initial set of key/value pairs that were specified in the framework's configuration options initBotStorageData element. If this is not set, new bots start off with no key/value pairs until bot.store() is called.

When a bot despawns (is removed from a space), the key/value store for that bot instance will automatically be removed from the store. Framework currently has an in-memory store and a mongo based store. By default, the in-memory store is used. Other backend stores are possible by replicating any one of the built-in storage modules and passing it to the framework.storeageDriver() method.

The MongoStore (and potentially other stores that use a persistent storage mechanism), also support the following methods:

• initialize() -- this must be called before framework.storageDriver() and framework.start() are called, and will validate that the configuration is correct
• writeMetrics() -- is a new, optional, method for persistent storage adaptors that can be called to write breadcrumbs into the database that can be used to build reports on the bot's usage

See MongoStore, for details on how to configure this storage adaptor.

The redis adaptor is likely broken and needs to be updated to support the new functions. It would be great if a flint user of redis wanted to contribute!

Bot Accounts

When using "Bot Accounts" the major differences are:

• Webhooks for message:created only trigger when the Bot is mentioned by name
• Unable to read messages in rooms using the Webex API

Differences with trigger.args using Framework with a "Bot Account":

The trigger.args array is a shortcut in processing the trigger.text string. It consists of an array of the words that are in the trigger.message string split by one or more spaces. Punctation is included if there is no space between the symbol and the word. With bot accounts, this behaves a bit differently.

• If defining a framework.hears() using a string (not regex), trigger.args is a filtered array of words from the message that begins after the first match of bot mention.

• If defining a framework.hears() using regex, the trigger.args array is the entire message.

Ie: "https://proxy.mycompany.com:8090" | | [maxStartupSpaces] | number | | If specified, the maximum number of spaces with our bot that the framework will discover during startup. If not specified the framework will attempt to discover all the spaces the framework's identity is in and "spawn" a bot object for all of them before emitting an "initiatialized" event. For popular bots that belog to hundreds or thousands of spaces, this can result in long startup times. Setting this to a number (ie: 100) will limit the number of bots spawned before initialization. Bots that are driven by external events and rely on logic that checks if an appropriate bot object exists before sending a notification should not modify the default. Bots that are driven primarily by webex user commands to the bot may set this to 0 or any positive number to facilitate a faster startup. After initialization new bot objects are created ("spawned") when the bot is added to a new space or, if the framework receives events in existing spaces that it did not discover during initialization. In the case of these "late discoveries", bots objects are spawned "just in time". This behavior is similar to the way the webex teams clients work. See the Spawn Event docs to discover how to handle the different types of spawn events. | | [messageFormat] | string | "text" | Default Webex message format to use with bot.say(). | | [initBotStorageData] | object | {} | Initial data for new bots to put into storage. | | [id] | string | "random" | The id this instance of Framework uses. | | [webhookRequestJSONLocation] | string | "body" | The property under the Request to find the JSON contents. | | [removeWebhooksOnStart] | Boolean | true | If you wish to have the bot remove all account webhooks when starting.

Kind: event emitted
Properties

| Name | Type | Description | | --- | --- | --- | | bot | object | Bot Object | | id | string | Framework UUID | | addedBy | string | ID of user who added bot to space if available. Bots are typically spawned in one of three ways: 1) When the framework first starts it can look for up to options.maxStartupSpaces spaces that our bot is already part of. When discovered a new bot is spawned. No addedBy parameter will be passed in this case and the framework.initialized variable will be false. 2) After the framework has started if a user sends a message to a bot in an existing space that was not discovered during startup, a bot object is spawned for the "just in time" discovered space. Developers should never assume that all possible spaces were discovered during the framework's startup. No addedBy parameter will be passed in this case and the framework.initialized variable will be true. 3) After the framework has started, if a user adds our bot to a new space a membership:created event occurs which also spawns a bot. The framework will inlcude the addedBy parameter and framework.initialized will be true. A best practice In these cases, is to include application logic for the bot to "introduce itself" and/or do something with the information about the user who created the bot's membership |

Example

// DM the user who added bot to a group space
framework.on('spawn', function(bot, flintId, addedById) {
    if (!addedById) {
     // don't say anything here or your bot's spaces will get
     // spammed every time your server is restarted
     framework.debug(`Framework spawned a bot object in existing
        space: ${bot.room.title}`);
  } else {
    if ((bot.room.type === 'group') && (addedById)) {
      // In this example we imagine our bot is only allowed in 1-1 spaces
      // our bot creates a 1-1 with the addedBy user, and leaves the group space
      bot.dm(addedById, `I see you added me to the the space "${bot.room.title}", ` +
        `but I am not allowed in group spaces.  ` +
        `We can talk here if you like.`).then(() => bot.exit());
    } else {
      bot.say(`Thanks for adding me to this space.  Here is what I can do...`);
