This is a demo Contacts Application built with the Phoenix Framework, featuring OAuth2 authentication via Google, full CRUD operations, pagination, search functionality, and CSV import/export capabilities.

• OAuth2 Authentication: Utilizes the Assent library for Google authentication.
• CRUD Operations: Create, read, update, and delete contacts.
• Pagination: Efficiently navigates through contact lists.
• Search: Quickly find contacts using the search feature.
• CSV Import/Export: Import and export contacts via CSV files.

Before setting up the application, ensure you have the following installed:

• Elixir: Version 1.14 or later. Installation Guide
• Erlang: Version 24 or later. Installation Guide
• PostgreSQL: Ensure it's installed and running. Installation Guide

git clone https://github.com/joangavelan/contactly.git
cd contactly

Fetch and install the necessary dependencies:

mix deps.get

The application requires specific environment variables for Google OAuth2 authentication. Create a file named .env in the project root and add the following variables:

export GOOGLE_CLIENT_ID=your_google_client_id
export GOOGLE_CLIENT_SECRET=your_google_client_secret
export GOOGLE_REDIRECT_URI=http://localhost:4000/auth/google/callback

Replace your_google_client_id and your_google_client_secret with your actual Google OAuth2 credentials. The GOOGLE_REDIRECT_URI should match the redirect URI configured in your Google Developer Console.

Configure your database settings in config/dev.exs. Ensure the username, password, hostname, and database fields match your PostgreSQL setup:

config :contactly, Contactly.Repo,
  username: "your_db_username",
  password: "your_db_password",
  hostname: "localhost",
  database: "contactly_dev",

Set up the database by running:

mix ecto.create
mix ecto.migrate

Start the Phoenix server while loading the .env file using the following command:

source .env && mix phx.server

The source .env command ensures your environment variables are loaded, and mix phx.server starts the application. The app will be accessible at http://localhost:4000.
