Tiger.AppConfig is a library integrating AWS AppConfig values into the Microsoft.Extensions.Configuration configuration ecosystem. Just as values from the command line, environment variables, JSON files, or User Secrets can be integrated into a unified, strongly-typed configuration, configuration values from AWS AppConfig can be, as well.

Setup is performed in the same manner as any other Microsoft.Extensions.Configuration configuration. Ideally, this is performed in CloudFormation. If a required identifier is not present, the configuration retrieval will fail. The required identifiers are these:

• Application: The identifier of an AWS::AppConfig::Application
• Environment: The identifier of an AWS::AppConfig::Environment
• ConfigurationProfile: The identifier of an AWS::AppConfig::ConfigurationProfile

In CloudFormation, these values can be retrieved by applying the intrinsic function !Ref to resources of the specified resource type.

Add the AppConfig configuration to the application configuration with the extension method for IConfigurationBuilder, similar to any other configuration source. For example:

hostBuilder.ConfigureAppConfiguration(b => b.AddAppConfig())

This should be applied to the host builder for the Lambda entry point of the application.

If the configuration identifiers are located under a section other than the default "AppConfig", that name can be provided as an argument to the call to AddAppConfig. Tiger.AppConfig reads the environment variables used to configure the AppConfig extension itself as necessary.

Seriously, though. Thank you for using this software. The author hopes it performs admirably for you.
