The code imports modules from a main module, initiates an asynchronous execution context, and uses promise handling to execute and process results from a getSettings function. The getSettings function is called with an email address and returns a promise that is handled with .then for successful results and .catch for errors.

Cell 2

var importer = require('../Core');
var getSettings = importer.import("google contact settings");

$.async();
getSettings('megamindbrian@gmail.com')
    .then(r => $.sendResult(r))
    .catch(e => $.sendError(e))

// Import the necessary modules
const core = require('../Core');

// Extract the getSettings function from the core module
const { getSettings } = core.import('google contact settings');

// Define a logger function
const log = (message) => {
  console.log(`[Llama]: ${message}`);
};

// Define an error handler function
const handleError = (error) => {
  log(`Error occurred: ${error.message}`);
  // Send the error to the caller
  $.sendError(error);
};

// Define a result handler function
const handleResult = (result) => {
  log('Result received');
  // Send the result to the caller
  $.sendResult(result);
};

// Function to get and handle the Google contact settings
const getContactSettings = async (email) => {
  try {
    // Call the getSettings function with the provided email
    const result = await getSettings(email);
    // Handle the result
    handleResult(result);
  } catch (error) {
    // Handle any errors that occur
    handleError(error);
  }
};

// Call the getContactSettings function with the specified email
$.async();
getContactSettings('megamindbrian@gmail.com');

Code Breakdown

Importing Modules

var importer = require('../Core');
var getSettings = importer.import('google contact settings');

• require('../Core') imports the main module (../Core.js) and assigns it to the importer variable.
• importer.import('google contact settings') imports a specific module named 'google contact settings' from the main module and assigns it to the getSettings variable.

Asynchronous Execution

$.async();

• $.async() is a method that initiates an asynchronous execution context.

Getting Settings and Handling Results

getSettings('megamindbrian@gmail.com')
   .then(r => $.sendResult(r))
   .catch(e => $.sendError(e))

• getSettings('megamindbrian@gmail.com') calls the getSettings function with the email address'megamindbrian@gmail.com' as an argument and returns a promise.
• .then(r => $.sendResult(r)) handles the resolved value of the promise (r) by calling the $.sendResult function with r as an argument. If the promise is resolved successfully, this callback will be executed.
• .catch(e => $.sendError(e)) handles the rejected value of the promise (e) by calling the $.sendError function with e as an argument. If the promise is rejected, this callback will be executed.
