Login with Google using OAuth2 for client-side web app, completes login flow discribed in Using OAuth 2.0 for Client-side Applications.
- Load the script with
<script>or as an AMD module.
- Create an instance of the library with
var go2 = new GO2(options), where options should contain at least the
clientIdyou got from the Google API Console.
- Attach your callbacks to
go2.onlogout. You will be able to get the
onlogincallback or from the
- (Immediate mode) At this point, you may call
go2.login(false, true)and to silently test and regain the previous approval. If it's approved,
onlogincallback will fire.
go2.login()to start an interactive login process, with a popup. The call must be a result of a user action, such as a click, to prevent popup blocker.
Check out comments in the script source code for detail.
- clientId: string (required)
- redirectUri: string (optional)
- scope: string | string (optional)
- popupHeight: number (optional)
- popupWidth: number (optional)
- responseType: string (optional)

library supplied by Google and reinvent the wheel?Why not use
Because I can; also because the library is light-weighted and transparent to me.
For some reason, I cannot get
auth library to load without getting the entire client library;
onload callback never fires.
You are very welcome to use the library from Google since it will be better supported.
What can I do with the
code I got once the login is completed?
- Use the token to request data from Google's server directly from the client-side web app in the browser (with JSON-P or CORS), for example, this is how HTML5 Word Cloud does it.
- Send the token to your own server, verify it with Google to associate a Google account with a user session on your site. Documentation here.
Include the src/google-oauth2.d.ts for Typescript support.
To run tests, first you would need to pull the required QUnit and Sinon.JS library by running
git submodule init git submodule update
Then, start a localhost HTTP server, for example,
python -m SimpleHTTPServer 8009
Test with local fake OAuth endpoint
Point your browser to http://localhost:8009/test/?localtest=true to start testing. You will need to disable popup blocker to properly run the interactive test cases.
Test with the real Google OAuth endpoint
Point your browser to http://127-0-0-1.org.uk:8009/test/ to start testing. You will need to disable popup blocker to properly run the interactive test cases.
