Google-signin-vue NPM

google-signin-vue

This Package can be used for both vue and nuxt. Both Documentation are given below.

Project setup

npm install google-signin-vue

Basic Setup

To use this package, we must get the client-id from google.

Go to Google developer Console
Create a Project or select an existing project
Then goto oath consent tab on the left sidebar
Choose the option internal if this can be used only by the organization. For example, if you registered the organization like myowndomain.com, then anyone who has mail id with @mydomain.com registered with Gmail only can log in.
Choose the option external if anyone registered with Gmail can log in.
Then You can fill all the details.
In case you are testing in localhost, you can just enter application name (mandatory) and enter logo(optional)
Save the Details
Goto Credentials tab on the left sidebar
Select Create Credential
Select application type as a web application, specify a name.
In the Authorized javascript origins section, enter the project domain name.
In Case of localhost just type localhost, If the project running on a specific port, enter the port like localhost:XXXX.
Now you’ll get the credentials, use only the client-id, keep your client- secret confidential. client- secret should be provided only to the backend.
