GoogleLogin

An Igniter installer that patches an Ash Phoenix project with Google OAuth login, admin user support, and authenticated routing defaults.

Source: https://github.com/nettinho/google_login

Prerequisites

This installer is designed to run on top of a ash generated project such as:

mix igniter.new my_app --with phx.new --install ash,ash_phoenix \
  --install ash_postgres,ash_authentication \
  --install ash_authentication_phoenix --setup --yes

Installation

Add google_login as a dependency in your project's mix.exs:

def deps do
  [
    {:google_login, git: "https://github.com/nettinho/google_login.git"}
  ]
end

Then run:

mix deps.get
mix google_login.install

The installer will show a diff of all proposed changes and ask for confirmation before applying.

What it does

The installer applies the following changes to your project:

Google OAuth

• Adds a google strategy to the User resource (Accounts.User)
• Adds a register_with_google action with attribute mapping from Google user info
• Adds user attributes: email, given_name, family_name, picture, is_admin, confirmed_at
• Adds a unique_email identity
• Configures Secrets module with secret_for/4 clauses that read GOOGLE_CLIENT_ID, GOOGLE_CLIENT_SECRET, and GOOGLE_REDIRECT_URI from environment variables
• Removes the default add_ons block (e.g. log_out_everywhere) from the User resource

Authenticated routing

• Replaces the default ash_authentication_live_session :authenticated_routes block with one that mounts HomeLive at /
• Adds an ash_authentication_live_session :admin_routes block that mounts AdminLive at /admin
• Removes password-specific routes (reset_route, confirm_route, magic_sign_in_route)
• Removes the default PageController and its templates (replaced by HomeLive)

Admin support

• Adds an is_admin boolean attribute (default false) to the User resource
• Adds a live_admin_required guard to LiveUserAuth that checks is_admin
• Creates HomeLive (authenticated) and AdminLive (admin-only) LiveView pages

AshAdmin

• Relocates the AshAdmin dashboard route from /admin to /admin/ash inside the dev_routes block, so it doesn't conflict with the custom AdminLive page

UI & Branding

• Updates the app layout header with navigation, theme toggle, conditional admin link, user email, and sign-out
• Adds .env to .gitignore

After installation

1. Generate and run the database migration:

   mix ash_postgres.generate_migrations --name google_login
   mix ash_postgres.migrate

2. Set the required environment variables (e.g. in a .env file):

   GOOGLE_CLIENT_ID=your_client_id
   GOOGLE_CLIENT_SECRET=your_client_secret
   GOOGLE_REDIRECT_URI=http://localhost:4000/auth/user/google/callback

3. To make a user an admin, set is_admin: true on their record.

Idempotency

The installer is safe to run multiple times. It checks for existing strategies, secrets, routes, and modules before making changes, so re-running it will not create duplicates.
