Usage

import {TsGoogleDrive} from "ts-google-drive";
import {google} from "googleapis";
const tsGoogleDrive = new TsGoogleDrive({keyFilename: "serviceAccount.json"});

async function auth() {
  const drive1 = new TsGoogleDrive({keyFilename: "serviceAccount.json"});
  const drive2 = new TsGoogleDrive({credentials: {client_email: "", private_key: ""}});

  // https://www.npmjs.com/package/google-auth-library
  const drive3 = new TsGoogleDrive({oAuthCredentials: {access_token: ""}});
  const drive4 = new TsGoogleDrive({oAuthCredentials: {refresh_token: ""}, oauthClientOptions: {clientId: "", clientSecret: ""}});
}

async function getSingleFile() {
    const fileId = "";
    const file = await tsGoogleDrive.getFile(fileId);
    if (file) {
        const isFolder = file.isFolder;
    } 
}

async function listFolders() {
    const folderId = "";
    const folders = await tsGoogleDrive
        .query()
        .setFolderOnly()
        .inFolder(folderId)
        .run();
}

async function createFolder() {
    const folderId = "";
    const newFolder = await tsGoogleDrive.createFolder({
        name: "testing",
        parent: folderId,
    });

    // try to search for it again
    const foundFolder = await tsGoogleDrive
        .query()
        .setFolderOnly()
        .setModifiedTime("=", newFolder.modifiedAt)
        .runOnce();
}

// async function uploadAndDownload() {
//   const folderId = "";
//   const filename = "./icon.png";
//   const newFile = await tsGoogleDrive.upload(filename, {parent: folderId});
//   const downloadBuffer = await newFile.download();

//   // you have to use "googleapis" package
//   // of if you want stream
//   const drive = google.drive({version: "v3", auth: newFile.client});
//   const file = await drive.files.get({
//     fileId: newFile.id,
//     alt: 'media'
//   }, {responseType: "stream"});

//   file.data.on("data", data => {
//     // stream data
//   });
//   file.data.on("end", () => {
//     // stream end
//   });

//   // or use pipe
//   const writeStream = fs.createWriteStream('./output.png');
//   file.data.pipe(writeStream);
// }

async function search() {
    const folderId = "";
    const query = await tsGoogleDrive
        .query()
        .setFolderOnly()
        .inFolder(folderId)
        .setPageSize(3)
        .setOrderBy("name")
        .setNameContains("New");
    
    // or you can use any query https://developers.google.com/drive/api/v3/search-files
    query.setQuery("name = 'hello'");

    while (query.hasNextPage()) {
        const folders = await query.run();
        for (const folder of folders) {
            await folder.delete();
        }
    }
}

async function emptyTrash() {
    await tsGoogleDrive.emptyTrash();
}

Using Service Account

• Create a Google Cloud Project
• Create Service Account
  • Service account details > Choose any service account name > CREATE
  • Grant this service account access to project > CONTINUE
  • Grant users access to this service account ( > CREATE KEY
  • Save the key file into your project
• Enable Drive API
  • APIs and Services > Enable APIS AND SERVICES

• To access shared folder
  • Open the JSON key file, you will find an email [email protected].
  • Go to your Google Drive Folder and shared the edit permission to the email address.
• Create using serviceAccount.json

const drive1 = new TsGoogleDrive({keyFilename: "serviceAccount.json"});

• Create using client_email and private_key (which is available inside the services account JSON)

const drive2 = new TsGoogleDrive({credentials: {client_email: "", private_key: ""}});

Using OAuth

• You can take reference on below link how to grab an oauth access token
• https://medium.com/@terence410/using-google-oauth-to-access-its-api-nodejs-b2678ade776f
