Weather Check 🌦️

This is a simple weather web application built with Node.js, Express, and Docker. It fetches real-time weather data using the OpenWeather API and displays it to users. The app is containerized for easy development.

You can visit it on Render at the link in this repo’s description and test it yourself!

Features

• Fetches current weather data for any city using the OpenWeather API.
• Built with Express.js for fast and lightweight server-side logic.
• Containerized with Docker for consistent environments.

Prerequisites

Before you begin, ensure you have the following installed:

• Git
• Docker
• Node.js (optional, for local development without Docker)
• An OpenWeather API key (free tier available)

Getting Started

1. Clone the Repository 📥

Clone this repository to your local machine using HTTPS:

git clone https://github.com/whoosh09/weather-check.git
cd weather-check

Note: If you prefer SSH and have SSH keys set up with GitHub, use:

git clone git@github.com:whoosh09/weather-check.git

2. Set Up Environment Variables ⚙️

Create a .env file in the project root and add your OpenWeather API key:

OPENWEATHER_API_KEY=your_api_key_here

3. Run with Docker 🐳

The app is containerized using Docker for easy setup.

Build and Run the Docker Container 🟢

1. Build the Docker image:

   docker build -t weather-app .

2. Run the container, mapping the app’s port to your host and setting Google’s DNS to avoid EAI_AGAIN errors:

   docker run --dns 8.8.8.8 -p 3000:3000 --env-file .env weather-app

   • --dns 8.8.8.8: Uses Google’s DNS to resolve network issues.
   • -p 3000:3000: Maps port 3000 on your host to the container.
   • --env-file .env: Loads the environment variables from the .env file.

3. Open your browser and visit http://localhost:3000 to view the app.

4. Run Without Docker (Optional)

If you want to run the app directly with Node.js:

1. Install dependencies:

   npm install

2. Start the app with nodemon:

   nodemon index.js

3. Visit http://localhost:3000 in your browser.
