weather-utils 2.0.1

A utility package for weather data handling with AWS services

Environment Variables for weather_utils Library

The weather_utils library relies on environment variables for configuration. Before using the library, ensure the required environment variables are properly set.

Required Environment Variables:

• DYNAMODB_TABLE_NAME → The name of the DynamoDB table where weather data is stored.
• SNS_TOPIC_ARN → The ARN of the SNS topic used for sending weather alerts.

Setting Environment Variables:

For Linux/macOS, run:
export DYNAMODB_TABLE_NAME="WeatherDataTable"
export SNS_TOPIC_ARN="arn:aws:sns:us-east-1:123456789012:WeatherAlerts"

For Windows PowerShell, run:
$env:DYNAMODB_TABLE_NAME="WeatherDataTable"
$env:SNS_TOPIC_ARN="arn:aws:sns:us-east-1:123456789012:WeatherAlerts"

For AWS Lambda, set these variables in the Lambda function environment variables section.

Usage in weather_utils:

The library reads these environment variables dynamically:

import os
DYNAMODB_TABLE_NAME = os.environ.get("DYNAMODB_TABLE_NAME", "DefaultWeatherTable")
SNS_TOPIC_ARN = os.environ.get("SNS_TOPIC_ARN", "default_sns_topic")

Ensure these variables are configured before using the library in your application.
