phcurado/zoi

Zoi is an Elixir schema validation library that defines and validates data structures with support for coercion, custom refinements, and type-specific constraints. It integrates directly with Phoenix LiveView by converting schemas into HTML form structs and provides introspection capabilities to auto-generate human-readable documentation. The system includes a benchmarking suite for performance evaluation and comprehensive test coverage for core validation, JSON Schema encoding, and ISO date handling.

A new benchmarking tool has been added to the \bench\ directory to measure the performance of Zoi schema validation. The suite includes scripts to run specific test cases (primitives, complex structures, comparisons) or a quick smoke test, allowing users to evaluate Zoi's speed against libraries like Ecto and NimbleOptions.

bench · high confidence

Zoi now includes built-in support for Phoenix HTML forms via the new \Zoi.Form\ and \Zoi.FormData\ modules, which allow Zoi schemas to be directly converted into \Phoenix.HTML.Form\ structs for seamless use in LiveView and Phoenix templates. Additionally, the library adds a \Zoi.Describe\ module that introspects schema metadata to automatically generate human-readable documentation strings for fields, simplifying the creation of HexDocs or inline help text.

lib/zoi · high confidence

The library now includes \Zoi\, a schema validation library for Elixir that allows defining schemas for various data types (strings, integers, booleans, maps, etc.) with built-in validations like minimum/maximum values, regex patterns, and email formats. It supports coercion, custom refinements, transforms, and custom error messages. The previous \Xoi\ module has been removed.

lib · high confidence

The project has been renamed from Xoi to Zoi, updating the package name in the README and gitignore. This change introduces the initial project configuration, including a Credo linter setup (.credo.exs), tool version specifications for Elixir 1.20.0-rc.6 and Erlang 29.0 (.tool-versions), and a Coveralls configuration (coveralls.json). The repository also adds the Apache 2.0 License and a comprehensive Changelog documenting versions up to 0.18.7, alongside an updated README with usage examples and documentation references.
