## What it is
Codextended is a lightweight Swift library of extensions that augments the built-in Codable API with type inference-powered conveniences. It reduces boilerplate for encoding and decoding values, such as one-liner encode/decode calls and easy key-level customization.

## Use cases
- decode  into swift types with less boilerplate
- encode swift structs to  in one line
- provide default values for missing keys when decoding
- transform values during decoding
- simplify custom codable implementations
- avoid verbose JSONEncoder/JSONDecoder setup

## When to choose
- you use Swift's Codable and want terser, type-inferred encode/decode calls
- you need lightweight key-level customization without a full serialization framework
- you want a zero-dependency extension layer over Codable on macOS or Linux

## When to avoid
- you need serialization formats beyond what Codable supports
- you want a full-featured JSON mapping framework with heavy customization
- you need a library with frequent updates and active maintenance

## Facets
- artifact type: library
- maturity: maintenance
- function: serialization, parser
- domain: developer-tools, programming-languages, apis
- platform: -
- tags: codable, -parsing, type-inference, swift-package-manager, extensions, macos, linux, swift
