Pandatech.StartupEnvironmentCheck

Pandatech.StartupEnvironmentCheck is a lightweight library designed to validate required environment variables at application startup. It helps ensure that essential configurations are in place, preventing unexpected behaviors or failures due to missing environment variables.

Installation

You can install Pandatech.StartupEnvironmentCheck via NuGet Package Manager or by using the following command in your Package Manager Console:

Install-Package Pandatech.StartupEnvironmentCheck

Usage

Validating Environment Variables

You can use the EnvironmentVariableValidator.ValidateEnvironmentVariables method to validate required environment variables. Here's an example:

using StartupEnvironmentCheck;

public class Program
{
    public static void Main(string[] args)
    {
        var requiredEnvVars = new List<string> { "DB_CONNECTION_STRING", "API_KEY" };
        EnvironmentVariableValidator.ValidateEnvironmentVariables(requiredEnvVars);
        
        // Continue with the rest of the application startup
    }
}

Handling Missing Variables

If any required environment variables are missing, a MissingEnvironmentVariablesException will be thrown. This exception includes a detailed message listing the missing variables.

You can catch this exception to log the error or take other appropriate actions:

try
{
EnvironmentVariableValidator.ValidateEnvironmentVariables(requiredEnvVars);
}
catch (MissingEnvironmentVariablesException ex)
{
// Log the error or take other actions
}
