In a Code Node, you can use a selection of predefined NPM modules. On this page, you’ll find all the necessary information to run these modules in a Code Node.
You can use the moment.js module for parsing, validating, manipulation and displaying dates.

​
Usage

In a Code Node, call the following function:
moment(inp?:any, format?: any, strict?: boolean);

​
Example

the following example gets the current UTC time and date and outputs it back to the contact.
const utc = moment.utc();
api.output(utc);
For more information, see the Moment.js Documentation.
Lodash DocumentationCognigy.AI also supports the utility library Lodash within Code Nodes.

​
Usage

You can call functions of the Lodash module by using the following syntax:
_.keys(<OBJECT>);
You can use any Lodash function within a Code Node. See their documentation for further information.

​
Example

The following example shows a typical use-case and syntax of the Lodash module.
const favouriteFoods = ["pizza", "spaghetti", "burger"];
const last = _.last(favouriteFoods);
api.output(last);
In this example we’re extracting the last element of the favouriteFoods array and sending it as an output message.
XML-js DocumentationIn case you want to parse XML data, you can use this module.

​
Usage

Within a Code Node, you can call the following method:
const xml =
    '<?xml version="1.0" encoding="utf-8"?>' +
    '<note importance="high" logged="true">' +
    '    <title>Happy</title>' +
    '    <todo>Work</todo>' +
    '    <todo>Play</todo>' +
    '</note>';

const result = xmljs.xml2json(xml, { compact: true, spaces: 4 });

// result will now contain a JSON representation of the xml above

​
