# ASR-0003: Uniform codec API and Source abstraction
|
|
|
|
## Context
|
|
|
|
Users switch between YAML, JSON, INI, and env-file formats; a different function surface per format would increase cognitive load and test matrices.
|
|
|
|
## Decision
|
|
|
|
1. Every format package exports **`New(opts...) *Codec`** with **`Map`**, **`Unmarshal`**, **`UnmarshalContext`**, **`Marshal`**, **`WriteTo`**.
|
|
2. Bytes, readers, files, and URLs are modeled by **`internal/source.Source`** with **`Open(ctx) (io.ReadCloser, error)`**.
|
|
3. HTTP(S) sources support **`WithHTTPHeader`** and **`WithHTTPClient`**.
|
|
|
|
## Consequences
|
|
|
|
- Cross-format examples in the README stay structurally identical.
|
|
- URL behaviour is testable with `httptest` against our client only.
