The code imports a module from a file named Core and uses it to run a Selenium cell with the argument 'messages from facebook'. The result of the Selenium cell is then processed through a series of promise chains and error handling blocks to ultimately send the result to the $. object.

Cell 5

var importer = require('../Core');
var runSeleniumCell = importer.import("run selenium cell");

$.async();
runSeleniumCell('messages from facebook')
    .then(func => func('https://www.facebook.com/messages/t/jaimeneufer'))
    .then(r => $.sendResult(r))
    .catch(e => $.sendError(e))

// Import required modules
import Core from '../Core';
import { runSeleniumCell } from Core.imports;

// Initialize asynchronous mode
$.async();

// Define a function to run Selenium cell
const runFacebookMessages = async () => {
  try {
    // Run Selenium cell with given message
    const result = await runSeleniumCell('messages from facebook');
    
    // Navigate to the desired Facebook conversation
    const conversationUrl = 'https://www.facebook.com/messages/t/jaimeneufer';
    const response = await result(conversationUrl);
    
    // Send the result
    $.sendResult(response);
  } catch (error) {
    // Catch any errors and send them as an error
    $.sendError(error);
  }
};

// Run the function
runFacebookMessages();

Code Breakdown

Importing Modules

var importer = require('../Core');
var runSeleniumCell = importer.import('run selenium cell');

• The code imports a module from a file named Core located two directory levels up.
• The imported module is assigned to the variable importer.
• The importer variable is used to import a function named runSeleniumCell from the Core module.

Initializing and Running the Code

$.async();
runSeleniumCell('messages from facebook')
   .then(func => func('https://www.facebook.com/messages/t/jaimeneufer'))
   .then(r => $.sendResult(r))
   .catch(e => $.sendError(e))

• The code calls the async function on an object named $.
• It runs the runSeleniumCell function with the argument 'messages from facebook'.
• The runSeleniumCell function returns a promise, which is then chained with then blocks.
  • The first then block takes the resolved value from the promise and passes it as an argument to a function returned by the promise.
  • This function takes a URL 'https://www.facebook.com/messages/t/jaimeneufer' as an argument.
  • The resolved value from the function call is passed to the next then block.
  • The second then block calls the sendResult function on the $. object with the resolved value.
• The final catch block catches any errors that occurred during the execution and passes them to the sendError function on the $. object.
