The code imports necessary modules, defines an options object, and exports a scheduleSearch function that creates a new event on a Google Calendar with a customizable search query. The scheduleSearch function checks for authentication, creates a new event, and returns a Promise that can be resolved with the event's details.

Run example

npm run import -- "schedule search all"

schedule search all

var google = require('googleapis');
var importer = require('../Core');
var {
    getOauthClient,
    ISODateString,
    createNewEvent,
} = importer.import("convert date iso",
"create new calendar event",
"import google calendar api");

var options = {
    calendarId: 'aws'
}

function scheduleSearch(search) {
    const parameters = {
        query: search || 'search engines'
    }
    const newDate = new Date();
    return (typeof options.auth === 'undefined'
           ? getOauthClient(options)
           : Promise.resolve([]))
        .then(() => createNewEvent('meta search all', JSON.stringify(parameters, null, 4), options))
}
module.exports = scheduleSearch;

```javascript
// Import required modules
const { google } = require('googleapis');
const importer = require('../Core');
const { getOauthClient, ISODateString, createNewEvent } = importer.import([
  'convert date iso',
  'create new calendar event',
  'import google calendar api',
]);

/**
 * Options for interacting with Google Calendar API
 */
const defaultOptions = {
  calendarId: 'aws',
};

/**
 * Function to schedule a search on Google
 * @param {string} search - Search query (optional)
 * @returns {Promise} Resolved Promise with the result of creating a new event
 */
function scheduleSearch(search) {
  const searchQuery = search ||'search engines';
  const parameters = {
    query: searchQuery,
  };
  const newDate = new Date();

  // Implement TODO: Implement caching of OAuth client for performance optimization
  return (typeof defaultOptions.auth === 'undefined'
   ? getOauthClient(defaultOptions)
    : Promise.resolve({})) // Return an empty object instead of an empty array
   .then(() => {
      // Implement TODO: Validate and sanitize input parameters
      return createNewEvent('meta search all', JSON.stringify(parameters, null, 4), defaultOptions);
    })
   .catch((error) => {
      // Implement TODO: Log and handle errors
      console.error('Error scheduling search:', error);
      return null;
    });
}

module.exports = scheduleSearch;
```

Code Breakdown

Importing Modules

The code starts by importing required modules:

• google is required from googleapis library, which provides a Node.js client for Google's API.
• importer is required from a local file ../Core, which exports functions and variables.
• importer.import is called with an array of strings, which returns an object containing three functions:
  • getOauthClient: likely used to authenticate with Google API.
  • ISODateString: probably used to format dates according to ISO standard.
  • createNewEvent: used to create a new event on a Google Calendar.

Defining Options

An object options is defined with a single property calendarId set to 'aws'.

scheduleSearch Function

The scheduleSearch function takes an optional search parameter and returns a Promise.

• parameters object is created with a query property set to search if it's provided, otherwise set to 'search engines'.
• A new Date object is created and assigned to newDate.
• The function checks if options.auth is undefined. If it is, it resolves with an empty array. Otherwise, it calls getOauthClient with options as an argument, which returns a Promise.
• The resulting Promise is then chained with another .then block, which calls createNewEvent with the following arguments:
  • Event title: 'meta search all'.
  • Event description: a JSON stringified version of parameters object.
  • options object.

Exporting scheduleSearch Function

The scheduleSearch function is exported as a module, making it available for use in other parts of the application.
