The code is a Node.js module for rendering and templating card data in a Google Sheets integration, utilizing ES6 syntax and promises for asynchronous operations. It consists of parsing card data, rendering cards with a unique document name, template data, and resources, and relies on external modules and functions for its functionality.

Run example

npm run import -- "render study sauce cards page"

render study sauce cards page

var uuid = require('uuid/v1');
var {Readable} = require('stream');
var importer = require('../Core');
var getTemplates = importer.import("templates google sheet");
var wrapTemplate = importer.import("output google sheet template");
var getTemplateProperties = importer.import("google sheet template properties");

function parseCards(str) {
    return str.split('\n').map(line => {
        var values = line.split(',');
        return {
            type: values[0],
            prompt: values[1],
            answer: values[2],
            'possible-1': values[2],
            'possible-2': values[3],
            'possible-3': values[4],
            'possible-4': values[5]
        }
    })
}

// TODO: make this generic for use with user related packs and state changes?
function renderCards(cards) {
    if(typeof cards === 'string') {
        cards = parseCards(cards)
    }
    // TODO: create a document and render cards from that
    var name = uuid().substr(0, 5) + (new Date()).getTime();
    var properties = {}, templates;
    
    return getTemplates(process.env.DOCID)
        .then(t => {
            templates = t;
            templates['cards'].data.rows = properties['cards-data'];
            templates['cards-cards'] = {template: {rows: [[`{{> cards/cards-cards-link}}`]]}}
            return getTemplateProperties('app', properties, templates);
        })
        .then(() => getTemplateProperties('demo', properties, templates))
        .then(() => getTemplateProperties('cards-cards', properties, templates))
        .then(() => wrapTemplate('cards/' + name, 'cards', properties['cards-cards'], Object.assign(properties, {
            'cards-cards-link': '/cards/' + name,
            'cards-data': (cards || parseCards(properties['demo-text']))
                .map(c => Object.assign(c, {cards: '/cards/' + name}))
        })))
        .then(page => collectTemplateResources(
            `cards/${name}.html`,
            page,
            properties,
            templates,
            process.env.BUCKET))
        .then(resources => (console.log(resources), '/cards/' + name + '.html'))
}

module.exports = renderCards;

const { v1: uuid } = require('uuid');

const renderCards = async (cards) => {

Code Breakdown

The provided code appears to be a Node.js module that handles card data rendering and templating for a Google Sheets integration. It consists of the following main components:

Importing Dependencies

• uuid/v1: used to generate a unique identifier.
• stream: used for streaming-related functionality.
• importer: a custom module for importing other modules.
• getTemplates, wrapTemplate, and getTemplateProperties: imported functions from other modules for template handling.

Parsing Card Data

• parseCards: a function that takes a string of newline-separated card data and splits it into individual card objects. Each card object contains properties such as type, prompt, answer, and possible values.

Rendering Cards

• renderCards: a function that takes card data and returns a promise that resolves with the rendered card HTML. It performs the following steps:
  1. Checks if the input card data is a string and parses it if necessary.
  2. Creates a unique document name based on the current timestamp.
  3. Retrieves the template data from the Google Sheets using getTemplates.
  4. Updates the template data with card properties and links.
  5. Retrieves template properties for 'app', 'demo', and 'cards-cards' using getTemplateProperties.
  6. Wraps the template data with a wrapper function using wrapTemplate.
  7. Collects template resources using collectTemplateResources.
  8. Returns the rendered card HTML.

Notes

• The code uses ES6 syntax and promises for asynchronous operations.
• The TODO comments suggest areas for improvement, such as making the code generic for user-related packs and state changes.
• The code relies on external modules and functions, so its behavior may vary depending on the implementation of those modules.
