Installation

To create a new Express app, follow these steps:

1. Run the Generator:

   npx configure-express-app@latest

2. Navigate to Your Project Directory:

   cd your-project-name

3. Pre Installed Dependencies Automatically

4. Configure Environment Variables:

   Create a .env file in the root of your project and set your environment variables. A sample .env.example file is provided.

   cp .env.example .env

   Edit the .env file as needed.

5. Run the Application In Production:

   npm start

6. Development Mode:

   For development mode with live-reloading:

   npm run dev

Project Structure

Your Express app will have the following structure:

Usage

• Adding Routes: Define your routes in the routes directory. Create new files for different route groups and import them in routes/index.js.

• Creating Controllers: Implement your business logic in controllers, located in the controllers directory.

• Using Middleware: Add custom middleware in the middlewares directory.

• Database Models: Define your database models in the models directory. Ensure your database connection is configured in database/db.js.

• Environment Variables: Manage configuration settings through the .env file.

Scripts

The following scripts are available:

• npm start: Start the application.
• npm run dev: Start the application in development mode with Nodemon.
• npm run prettify: prettify your code using Prettier.

Security

• Helmet: Protects against known vulnerabilities by setting HTTP headers appropriately.
