webex-node-bot-framework

$3

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. This project is community supported so contributions are welcome. If you are interested in making the framework better please see the Contribution Guidelines.

News

* May, 2023 - Version 2.5.0 introduces two new elments of the Trigger object
* trigger.command will now contain the component of the user message that matched the framework.hears phrase.
* trigger.prompt will contain all of the user message that was NOT part of the command or the bot mention.

This should simplify logic that uses part of the user message, for example:
``js
// echo user input
framework.hears('echo', (bot, trigger) => {
bot.say('markdown', You said: ${trigger.prompt});
}, 'echo - I\'ll echo back the rest of your message');
`

This release also includes updated Contribution Guidelines including details on running the tests

* 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.


`js
// 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", () => {
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', (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:

`js
let priority = 0;
framework.hears(phrase, (bot, trigger, id) => {
bot.
.then((returnedValue) => {
// do something with returned value
})
.catch((err) => {
// handle errors
});
},'This is text that describes what happens when user sends phrase to bot', priority);
`

* phrase : This can be either a regex pattern or a string.
If a regex pattern is used, it is matched against the entire message text.
If a string, the phrase is matched if it is a substring of the room message.
(This behavior differs slightly when run with a user token, see Differences between Bot Accounts and User Accounts).
* bot : The bot object that is used to execute commands when the phrase is
triggered.
* bot. : 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.
* help text : Optional help text can be supplied after the function. This enables the framework.showHelp() method to automatically generate help messages for the bot.
* priority : Optional priority can be supplied after the function (or help text) to specify which function should be called when multiple phrases match. The hears() method(s) with the lowest priorities are called if priorities are set.

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:

`js
var newToken = 'Tm90aGluZyB0byBzZWUgaGVyZS4uLiBNb3ZlIGFsb25nLi4u';

framework.setWebexToken(newToken)
.then((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 vs. User Accounts.

Most Webex bots are built using a "Bot Account" that was created in Webex For Developers - Create A Bot.
It is also possible to build framework based applications using a "User Account" by specifying a user token obtained via a Webex Integration

When using "Bot Accounts" the major differences are:

* Webhooks and websocket events for message:created only trigger when the Bot is mentioned by name
* Unable to read all messages in Webex space using the Webex API.
* May request the details of individual messages via the API by specifying
a messageId. In group space the messageID must be for a message where the bot
was "mentioned". Bots can request info for any message in 1-1 spaces.

Differences with matching string phrases when using Framework with a "Bot Account":

* When running as a bot account and a framework.hears() is defined with a string phrase (as opposed to regex) the framework will convert the string to regex, for example: "string"
is converted to /(^| )string( |$)/i in order to see if the string exists as a substring
of the message.
* When running as a user account, a string phrase will match only against the first word of the message.
* Regex phrases behave the same in a framework.hears() for both Bot and User accounts

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.

Troubleshooting

A common complaint from new framework developers is "My bot is not responding to messages!". If this is happening to you, here are a few things to check:

1. Make sure you have configured your app with the token that belongs to the bot you are sending messages to.
2. Make sure your framework based app is up and running.
3. If using webhooks, make sure that your Webhook URL is reachable from the public internet. If you aren't sure how to test this, remove the webhookUrl key from your framework config object. This will use websockets which are more likely to work in development configurations.
4. If interacting with a bot in a group space, make sure to at-mention your bot when you send it a message. Only messages that specifically at-mention a bot by name are sent to the bot logic.

If you are having intermittent problems with your bot failing to respond to messages this may be a problem with the Webex services itself, a problem with the framework, or a problem with the way you have configured your framework.hears(...) methods. One way to isolate the problem is to add a handler for the internal framework log events, as follows

``javascript
framework.on('log', (msg) => {
console.log(msg);
});
`

This will cause your app to include framework logging which provides details about every message received, and every framework.hears() handler that is invoked in response to those messages. If you don't see the message you are sending to your bot, contact Webex developer support. If you do see the message, check the logs to validate that your framework.hears() handler is being called. You may need to modify the phrase. See the framework.hears documentation

Options Object

Kind: instance namespace of Framework
Properties

| Name | Type | Default | Description |
| --- | --- | --- | --- |
| token | string | | Webex Token. |
| [webhookUrl] | string | | URL that is used for Webex API to send callbacks. If not set events are received via websocket |
| [webhookSecret] | string | | If specified, inbound webhooks are authorized before being processed. Ignored if webhookUrl is not set. |
| [httpsProxy] | string | | If specified the https proxy to route request to webex through. 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. |
| [supressDirectSpaceSpawnFailures] | boolean | true | When a bot has a 1-1 space with a webex user who is no longer active the bot will fail to spawn. By default these error messages are supressed. Set to false to see them. |

| [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. Ignored if webhookUrl is not set. |
| [removeDeviceRegistrationsOnStart] | Boolean | false | If you use websockets and get "excessive device registrations" during iterative development, this will delete ALL device registrations. Use with caution! Ignored if webhookUrl is set. |
| [restrictedToEmailDomains] | string | | Set to a comma seperated list of email domains the bot may interact with, ie "myco.com,myco2.com". For more details see the Membership-Rules README |
| [guideEmails] | string | | Set to a comma seperated list of Webex users emails who MUST be in a space in order for the bot to work, ie "user1@myco.com,user2@myco2.com". For more details see the Membership-Rules README |
| [membershipRulesDisallowedResponse] | string | | Message from bot when it detects it is in a space that does not conform to the membership rules specified by the restrictedToEmailDomains and/or the guideEmails parameters. Default messages is "Sorry, my use is not allowed for all the members in this space. Will ignore any new messages to me.". No message will be sent if this is set to an empty string. |
| [membershipRulesStateMessageResponse] | string | | Message from bot when it is messaged in a space that does not conform to the membership rules specified by the restrictedToEmailDomains and/or the guideEmails parameters. Default messages is "Sorry, because my use is not allowed for all the members in this space I am ignoring any input.". No message will be sent if this is set to an empty string. |

}, 'help - shows information about commands I understand', 0);

// This catchall handler does not include a help message, but it
// does set a high preference value so it will not be called if any
