Valpa (Valpa v0.1.0)

Valpa is a composable validation library for Elixir.

It supports validation of raw values, {:ok, _} and {:error, _} tuples with pipelined field validations and automatic error propagation.

Features include:

Simple, reusable validation functions for values and maps/structs
Optional and required variants for all validators
Extensible with custom validators
Detailed error reporting with rich metadata
