Envied

Overview

ENVied is a project designed to ensure the presence and proper typing of environment variables within applications, making it particularly beneficial for developers who rely heavily on configuration settings for their apps. Although it's noted that this project is no longer maintained and a modern replacement exists, the features that ENVied provides can greatly assist in enhancing the robustness of any application’s environment variable management.

The utility of ENVied lies in its ability to not only check the existence of environment variables but also to coerce them into the correct types such as integers and booleans. This helps prevent common pitfalls associated with misconfigured environment settings, particularly when deploying to platforms like Heroku.

Features

• Presence and Correctness Checking: ENVied verifies that essential environment variables are present and correctly formatted, throwing errors when issues arise.

• Type Support: Access typed environment variables, enabling developers to retrieve integers, booleans, and more instead of just strings, which fosters better type safety.

• Heroku Configuration Verification: Specific support for checking the correctness of environment variables configured on Heroku, ensuring that they meet the required standards.

• Flexible Key Alias: The ability to define a key alias allows for dynamic selection of environment variable values based on the runtime condition, simplifying management across development and test environments.

• Comprehensive Type Handling: Supports various data types including arrays, booleans, dates, floats, hashes, integers, strings, symbols, times, and URIs, making it versatile for different application needs.

• Error Prevention: With detailed coercion functionality, ENVied helps avoid runtime errors by ensuring environment variables are of the expected data types before they are used in the application.

• Command-Line Interface: A user-friendly command-line interface simplifies the configuration and management of your environment variables, making it easy to integrate into your workflow.
