Config Transform is a library for deserializing configuration files from a
map[string]interface{} to a struct type. It is commonly used with JSON and
YAML configuration files.
Features include:
- generate documentation from comments on the
struct - custom deserialization of user defined types
- useful error messages when transformation fails
- additional user-defined field validation
Both encoding/json and go-yaml provide functions for deserializing from
a config file, but each have their significant shortcomings:
- the error messages returned by
encoding/jsondo not include enough information to actually find and fix the error go-yamldoes not support polymorphic types- supporting multiple config formats (json, yaml, ini, toml, etc) requires that you annotate your structs for each format
- no support for generated documentation
- no user-defined type validation
