env is a Go library that reads environment variables and populates the fields of a Go struct according to tag directives. It uses reflection to iterate over struct types and tags at runtime, mapping environment variable names to struct fields and applying parsing behavior defined in struct tags. The library supports required field validation, returning errors when marked fields are missing or empty after parsing. It also provides default value fallback from struct tags when environment variables are not set, environment variable expansion that recursively substitutes references within values,

envconfig is a Go configuration decoder and environment variable mapper that deserializes environment variables into structured Go data types. It provides tools for validating mandatory fields and ensuring application configuration adheres to the external configuration patterns of twelve-factor app compliance. The library features a help generator that creates formatted usage text based on struct definitions to describe expected environment variables. It also includes a validation tool capable of detecting unused environment variables that match a specific prefix but do not correspond to any

Dynaconf est une bibliothèque de gestion de configuration pour les applications Python qui fournit un système unifié pour charger, valider et gérer les paramètres. Elle agrège les données de configuration depuis plusieurs fichiers, variables d'environnement et magasins externes en un seul objet en utilisant un ordre de priorité défini.
