Clean Air Tracker

https://cleanairtracker.kro.kr/

Project Description

Clean Air Tracker is a website that utilizes the AirKorea OpenAPI from the Korea Environment Corporation to provide real-time air quality information, including particulate matter, fine particulate matter, and ozone. The website is developed using Express, TypeScript, Svelte, PostgreSQL, and TypeORM. Through this site, users can easily check the current air quality status of various regions across the country.

Features

Real-Time Air Quality Information: Users can view real-time air quality information for selected locations.
Database Storage: Collected air quality data is stored in a database, providing historical data access.
Automatic Data Updates: Air quality data is automatically updated at set intervals.

Getting Started

This section details the prerequisites and installation steps needed to get the project running locally.

Prerequisites

Node.js (v14 or higher)
npm (Node Package Manager)
TypeScript
TypeORM
PostgreSQL or a compatible SQL database

Installation

Clone the project:

git clone https://github.com/krkarma777/CleanAirTracker.git
cd [Cloned Directory Name]

Install necessary packages:
```
npm install
```
Create an environment configuration file (.env):
```
# .env
API_KEY=[Your API key]
```

Configure the database connection: Add the ormconfig.js file to the root of your project directory with the following content:

module.exports = {
    type: "postgres",
    host: "localhost",
    port: 5432,
    username: "CleanAirTracker",
    password: "root",
    database: "CleanAirTracker",
    synchronize: true, // Note: set this to false in production to avoid unintended data loss
    logging: false,
    entities: [
        "dist/**/*.entity.js" // Ensure this path matches your compiled files
    ]
}

This configuration sets up the database connection for your PostgreSQL database. Adjust the settings as necessary to match your environment.

Setting Up HTTPS: For secure communication, you need to set up HTTPS by obtaining SSL/TLS certificates. Place the following files in your project directory under src/config:
- private.key: Your private key file.
- certificate.crt: Your SSL/TLS certificate.
- ca_bundle.crt: Certificate authority bundle.
Start the application: To run the server locally, use the following command:
```
cd svelte-app
npm run build
cd ..
npm run build
npm start
```

Usage

After starting the server, navigate to https://localhost:443 in your web browser to view the Clean Air Tracker site. You can interact with the real-time data and explore different regions' air quality metrics.
