RELEASE NOTES

koreUtil Libraries

koreUtil libraries provide pre-written JavaScript functions which makes common or complex tasks easy to implement. These libraries often target specific tasks such as setting up recurring rules for calendar, parsing and manipulation of dates, conversion of dates between timezone, tools to simplify programming with strings, numbers, arrays, functions and objects etc.

How to Use

koreUtil libraries can be used anywhere in the bot where there is a flexibility to write JavaScript code such as script node, message node, confirmation node, entity node, standard responses, answers to FAQs, small talk, event handlers etc.

List of koreUtil libraries

Below is the list of koreUtil libraries provided by the platform:

koreUtil.rrule

koreUtil.rrule is platform offered JS library for creating new recurrence rules, interpreting and reading them in human readable format. This library is backed by rrule npm module version 2.2.0 installed on Kore.ai server. For more details on using rrule refer here.

Usage Example:
context.rule = new koreUtil.rrule({
freq: koreUtil.rrule.WEEKLY,
interval: 5,
byweekday: [koreUtil.rrule.MO, koreUtil.rrule.FR],
dtstart: new Date(2012, 1, 1, 10, 30),
until: new Date(2012, 12, 31)
});

context.between=context.rule.between(new Date(2012, 7, 1), new Date(2012, 8, 1));
context.readableFormat=context.rule.toText();

Output:

  • For context.between
    [
    "2012-08-27T10:30:00.000Z",
    "2012-08-31T10:30:00.000Z"
    ]
  • For context.readableFormat
    every 5 weeks on Monday, Friday until January 31, 2013

koreUtil.getCurrentOptions

koreUtil.getCurrentOptions is a platform offered JS library which provides utility functions to get the current template for language selection standard response options. This can be used to customize the standard response.
Post the release of v8.1, this function has been enhanced to return the authorization URL used in the standard response when end-user authorization is requested.

Following is the return format for each of the situations:

  • For the language selection standard response:
    {"list_of_languages": [
       {"title": "English","value": "English"},
       {"title": "Deutsche","value": "Deutsche"},
       {"title": "Español","value": "Español"}
    ]}
  • For the language ambiguity standard response:
    {"current_language": "Español",
          "list_of_new_languages": [
             {"title": "English","value": "English"},
             {"title": "Deutsche","value": "Deutsche"},
             {"title": "Español","value": "Español"}
      ]}
  • For the language switch standard response:
    {"new_language": "Español","current_language": "English"}
  • For User authorization request standard response:
    {
        "authorizationURL": "https:///r/xxxxxxxxxxxxx"
    }

Following are the usage examples of how the above utility can be used to render the message in a button template, you can use any template as per your requirements.  See here for more on message templates.

Usage Example 1: To get the standard response for “Ask if the user would like to select any of the languages

var info = koreUtil.getCurrentOptions();
var message = {
  "type": "template",
  "payload": {
    "template_type": "button",
    "text": "please select your laguage",
    "subText": "Button Template Description",
    "buttons": []
    }
  };
for (i = 0; i < info.list_of_languages.length; i++) {
  var button = {
    "type": "postback",
    "title": info.list_of_languages[i].title,
    "payload": info.list_of_languages[i].value
    };

  message.payload.buttons.push(button);
 }
print(JSON.stringify(message));

Usage Example 2: To get the standard response for “Ask if the user would like to switch to any of the new languages detected during a conversation

var info = koreUtil.getCurrentOptions();
var message = {
    "type": "template",
    "payload": {
        "template_type": "button",
        "text": "language abiguity response for the current language" + info.current_language,
        "subText": "Button Template Description",
        "buttons": []
    }
};
for (i = 0; i < info.list_of_new_languages.length; i++) {
    var button = {
        "type": "postback",
        "title": info.list_of_new_languages[i].title,
        "payload": info.list_of_new_languages[i].value
    };

    message.payload.buttons.push(button);
}
print(JSON.stringify(message));

Usage Example 3: To get the standard response for “Ask if the user would like to switch to any of the new languages detected during a conversation

var info = koreUtil.getCurrentOptions();
var message = {
    "type": "template",
    "payload": {
        "template_type": "button",
        "text": "would you like to switch to new language detected: current language " + info.current_language + "new language : " + info.new_language,
        "subText": "Button Template Description",
        "buttons": []
    }
};
var options = ["yes", "no"]
for (i = 0; i < options.length; i++) {
    var button = {
        "type": "postback",
        "title": options[i],
        "payload": options[i]
    };
    message.payload.buttons.push(button);
}
print(JSON.stringify(message));

Usage Example 4: To get the standard response for “User needs to authorize or re-authorize

var info = koreUtil.getCurrentOptions();

var message = {
    type: 'template',
    payload: {
        template_type: 'button',
        text: 'Please authorize before we continue...',
        buttons: [
            {
                type: 'url',
                title: 'Click here to authorize',
                url: info.authorizationURL
            }
        ]
    }
};

print(JSON.stringify(message));

koreUtil.getSessionId

koreUtil.getSessionId is a platform offered JS library for obtaining the current conversation session Id.

Usage Example:
var sessionId = koreUtil.getSessionId();

Output:

  • For sessionId:
    5x54321x11xx87654321xx12
