Secrets Logger - This project showcases a web application that allows users to register, log in, and share secrets. It's built using Express.js and integrates local authentication as well as Google OAuth 2.0 for user login.

• User Registration and Authentication: Users can register with a unique username and password. Passport.js is used with the Local Strategy for secure user authentication.
• Google OAuth 2.0: Users can also log in using their Google accounts through OAuth 2.0. The GoogleStrategy from Passport.js is employed to handle Google authentication.
• Share and Display Secrets: Authenticated users can submit their secrets, which are stored and displayed on the "Secrets" page.
• User Session Management: The app manages user sessions, allowing users to remain logged in across different pages until they choose to log out.

• Node.js: The server-side runtime environment for running JavaScript code.
• Express.js: A web application framework for building robust and scalable applications.
• MongoDB: A NoSQL database used to store user information and secrets.
• Passport.js: An authentication middleware for Node.js that supports various authentication strategies.
• EJS: A templating engine for rendering dynamic HTML pages.
• Google OAuth 2.0: OAuth 2.0 authentication using Google accounts.

Follow these steps to set up the application locally on your machine:

1. Clone the Repository: Start by cloning this repository to your local machine using Git.

git clone

2. Install Dependencies: Navigate to the project directory and install the required dependencies.

npm install

3. Configure Google OAuth: Create a Google OAuth 2.0 credentials in the Google Developer Console:

• Set the authorized redirect URI to http://localhost:3000/auth/google/secrets.

4. Set Environment Variables: Create a .env file in the project root and add your Google OAuth credentials:

CLIENT_ID= CLIENT_SECRET=

5. Start the Server: Launch the application by running the following command:

npm start

6. Usage:

• Visit http://localhost:3000 in your web browser to access the home page.
• Click "Login with Google" to authenticate via Google OAuth 2.0.
• Once authenticated, you can submit your own secrets and view secrets submitted by other users.
• Logout by clicking the "Logout" button.

• The app uses Express.js to handle routing and server setup.
• Passport.js is used to manage authentication. It employs both local authentication (username and password) and Google OAuth 2.0.
• User data is stored in a MongoDB database. Mongoose is used for schema modeling and interaction with the database.
• EJS templates are used for rendering dynamic HTML pages, such as login, registration, and secrets display.

• public/: Static assets (CSS, images, etc.).
• views/: EJS templates for rendering HTML.
• models/: Mongoose schema models.
• app.js: Main Express application setup.

• /: Home page.
• /auth/google: Initiate Google OAuth 2.0 authentication.
• /auth/google/secrets: Google OAuth 2.0 callback URL.
• /login: User login page.
• /register: User registration page.
• /secrets: Display secrets submitted by users.
• /submit: Submit a secret.
• /logout: Log out the user.
