The listDrive function is a Node.js module that exports a single function, which returns a list of files from Google Drive after authenticating with Google Drive using the authorizeDrive function. The function retrieves the list of files using the files.list method and returns an empty array if no files are found.

Run example

npm run import -- "list google drive files"

list google drive files

var util = require('util');
var importer = require('../Core');
var authorizeDrive = importer.import("authorize google drive");

function listDrive() {
    return authorizeDrive()
        .then(drive => util.promisify(drive.files.list.bind(drive))({}))
        .then(r => r.data.files || [])
}

module.exports = listDrive;

What the code could have been:

// Import the necessary modules
const { promisify } = require('util');
const importer = require('../Core');
const { google } = require('googleapis'); // Import the google-api-library
const authorizeDrive = importer.import('authorizeGoogleDrive'); // Refactor import statement

/**
 * List files from Google Drive.
 *
 * @returns {Promise>} A promise that resolves to an array of Google Drive files.
 */
async function listDrive() {
    // Authorize access to Google Drive
    const drive = await authorizeDrive();

    // List files from Google Drive using the google-api-library
    const files = await drive.files.list({});

    // Return the list of files
    return files.data.files || [];
}

module.exports = listDrive;

Function Breakdown

This code defines a Node.js module that exports a single function, listDrive, which returns a list of files from Google Drive.

Imported Modules

util: provides utility functions for Node.js
importer: an internal module that imports other modules (not shown in the code snippet)
authorizeDrive: a function imported from importer that handles Google Drive authorization

Function: `listDrive`

authorizeDrive(): Calls the authorization function to authenticate with Google Drive.
.then(drive =>...): Once authorized, retrieves the drive object and uses util.promisify to convert the files.list method into a promise-based function.
.then(r => r.data.files || []): Calls the promise-based files.list function with an empty object ({}) as arguments. If the response contains a data property with a files array, it returns that array; otherwise, it returns an empty array ([]).
