While the 12 Factor App advocates for using environment variables in configuration, I felt the need for a more comprehensive solution. This realization prompted the creation of Constructor, a lightweight Go library/module. Its purpose is to streamline the configuration process by simplifying structs through tags, default values, and support for overrides from YAML files, environment variables, and flags.
In summary, Constructor is designed to elevate the configuration experience in Go, providing an efficient and versatile solution to eliminate repetitive tasks across various applications.
