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.

Moment.js

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

Cognigy.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.

Messenger Platform

In 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
