webpack-validator - Validates your webpack config with Joi

•    Javascript

---

Writing webpack configs is brittle and error-prone. This package provides a joi object schema for webpack configs. This gets you a) static type safety, b) property spell checking and c) semantic validations such as "loader and loaders can not be used simultaneously" or "query can only be used with loader, not with loaders". You're very welcome to give feedback & PR's.

relish - Better error messages for Hapi.js Joi validation

•    Javascript

Joi provides awesome schema validation, but the error messages returned are not user-friendly. This package returns a more user-friendly version of Joi's default response and allows for custom error messages. Once initialized, this package exposes a custom failAction handler that can be used in your Hapi.js Route Options.

joi-to-json-schema

•    Javascript

---

The goal is to provide best effort conversion from Joi objects to JSON Schema (draft-04) with the understanding that only some of Joi's schematics can be converted directly. Primarily this module exists to convert Joi schema objects for existing tools which happen to currently consume JSON Schema. Joi's conditional form, i.e. .when('name',{is:cond,then:joi,otherwise:joi}), is evaluated at runtime and since, from the perspective of the schema, there is no way of knowing what the condition might resolve to, this module takes the position that it should provide all possible resolutions in a JSON Schema oneOf:[] clause.

schemer - A Joi-inspired interface for formatting and validating data structures in PHP.

•    PHP

---

Schemer is a Joi-inspired library for validating and formatting data structures. Complex structures' validators can be constructed by composition. We see that age is now an integer, and the friends key has been created with an empty array, as per the formatting instructions. When handling data from other sources, you'll probably want to attempt to format the data before validating it.
