Install : Adding the library

Simple download the lib

Download the files in the lib folder: login.service.js and drive.service.js. Add them to your app, for instance:

<script src="../lib/login.service.js"></script>
<script src="../lib/drive.service.js"></script>

Bower

  bower install gdrive-sync-js --save

Then import the library

<script src="../bower_components/lib/login.service.js"></script>
<script src=".../bower_components/lib/drive.service.js"></script>

Npm

  npm install gdrive-sync-js --save

Then import the library

  <script src="../node_modules/gdrive-sync-js/lib/login.service.js"></script>
  <script src="../node_modules/gdrive-sync-js/lib/drive.service.js"></script>

How to use it

After the lib is loaded you can use the new service like this

      var SCOPES = 'https://www.googleapis.com/auth/drive.file'
      var CLIENT_ID = 'YOUR CLIENT ID';
      DISCOVERY_DOCS = ['https://www.googleapis.com/discovery/v1/apis/drive/v3/rest'];
      window.loginService = new LoginService(CLIENT_ID, SCOPES, DISCOVERY_DOCS);

• SCOPES: scopes to request, as a space-delimited string.

• CLIENT_ID: The app's client ID, found and created in the Google Developers Console.

• DISCOVERY_DOCS: are the apis that we are going to use. An array of discovery doc URLs or discovery doc JSON objects.

For more info check the Demo

File Explorer Demo (list folders and files)

Add your api client_id to demo/fileExplorer/index.html. You can get the client id following the instruction from step1 here https://developers.google.com/drive/v3/web/quickstart/js

Clone, install and run

npm install
npm start // to run the dev server

Then go to http://localhost:4000/demo/fileExplorer

It will ask for signin using a google account, or automatically signin if you already authorized the app.

This demo list the folders and files from your root folder ordered by type and name. If you click in a folder it will open it and also will show in "selected resources" the folder id. If you select a file it will show you the file id.

Barebones Save Google doc Demo (list, save, load documents)

Add your api client_id to demo/index.html. You can get the client id following the instruction from step1 here https://developers.google.com/drive/v3/web/quickstart/js

Clone, install and run

npm install
npm start // to run the dev server

Then go to http://localhost:4000/demo

The demo uses jQuery but just for hide/show stuff, is not needed.

It will ask for signin using a google account, or automatically signin if you already authorized the app.

Write something and click save, it will create a file in your google drive called gDriveSync.example.txt.

If you change the text and save it again, it will update the file. Have in mind that if you refresh the page the doc id reference will be lost so if you save again it will create a new document.

The document has a mimeType of application/vnd.google-apps.document' this is a google doc, so you can open and edit it from google drive.

  • loadFileRaw: It loads a file given an ID. (parameter file)

  • saveFile: It creates a new google document (application/vnd.google-apps.document), or update an existing one if the file has an ID (parameter file) If the file object specified the parents parameter (array of folders ids) it will save the file in that specific folder.

  • loadFile: It loads a google document as text (plain/text) given an ID. (parameter file)

  • list: It return the files (id and name) from Google Drive (parameters: resource and callback function). resource= {query_name:'', parents:'', mimeType:'', trashed:false}

    • listFiles: It return the files (id and name) from Google Drive that contains the query_name. (parameters: query_name and callback function)
    • listFilesAt: It return the files (id and name) from Google Drive that contains the query_name and are at a specific folder (parents parameter). (parameters: query_name, parents and callback function)

  A file is just an object like

  var file = {id: null, name: 'testName', content:'hello' , parents:['folderId']}

  A resource is just an object like

  var resource = {query_name:'file_name', parents:'folderId', mimeType:'plain/text' ,trashed:false , orderBy: 'name'}

  This is used to pass options to the list method.

  • trashed: boolean value, true to show just files that are in the trash. false to not show them. not set to show everything.
  • orderBy: A comma-separated list of sort keys. Valid keys are 'createdTime', 'folder', 'modifiedByMeTime', 'modifiedTime', 'name', 'quotaBytesUsed', 'recency', 'sharedWithMeTime', 'starred', and 'viewedByMeTime'. Each key sorts ascending by default, but may be reversed with the 'desc' modifier.
