Implementing Google One Tap Sign-In for Django

This guide details the process for integrating Google's One Tap sign-in into your Django application, utilizing the Django development server alongside Google's JavaScript library to facilitate streamlined authentication. For comprehensive documentation and tutorials, refer to Google's Developer Guide on One Tap sign-in.

Setting Up the Django Development Server

Begin by ensuring your Django development server is up and running, particularly within our interview_db project framework.

# Move into your project directory
cd interview_db/

# Activate your virtual environment
source venv/bin/activate

# Launch the Django development server
python runserver

The output should confirm the server's active status. Should any problems arise, revisit the initial setup instructions or consult the project's GitHub repository for additional help.

Locating the Google One Tap JavaScript Library

Within the base.html file, situated at the end of the JavaScript block, you'll encounter the code snippet below. This segment incorporates Google's One Tap sign-in JavaScript library into your application:

<!-- Include Google's One Tap sign-in JavaScript library -->
<script src="" async defer></script>

{% if not request.user.is_authenticated %}
    <div id="g_id_onload"
         data-login_uri="{{ request.scheme }}://{{ request.META.HTTP_HOST }}{% url 'users:google-one-tap-login' %}">
{% endif %}

Incorporating Google's One Tap sign-in feature requires you to replace YOUR_GOOGLE_CLIENT_ID with your actual Google Client ID.
