This is a simple weather application that provides real-time weather data for any city. The application is built using HTML, CSS, and JavaScript for the frontend, with a serverless function backend deployed on Cloudflare Pages.

• public/: Contains the frontend assets (HTML, CSS, and JavaScript).
• functions/api/: Contains the serverless function that fetches weather data from an external API.
• .dev.vars: Local environment variables file for Wrangler.
• .dev.vars.example: An example file for the required environment variables.

1. Clone the repository:

   git clone <repository-url>
   cd <repository-directory>

2. Install dependencies:

   This project uses Wrangler to run locally and deploy. Make sure you have it installed and configured.

3. Set up environment variables:

   Create a .dev.vars file in the root of the project and add your weather API key:

   WEATHER_API_KEY=your_weather_api_key
   

   You can get a free API key from a provider like OpenWeatherMap.

To run the application locally, use the following Wrangler command:

wrangler pages dev public

To deploy the application to Cloudflare Pages, follow these steps:

1. Deploy the application:

   Run the following Wrangler command to deploy your project:

   After deploying, you need to add the WEATHER_API_KEY to your Cloudflare Pages project.

   • Go to your Cloudflare dashboard.
   • Navigate to Workers & Pages and select your project.
   • Go to Settings > Environment variables.
   • Add a new variable with the name WEATHER_API_KEY and your API key as the value.
