skema - 🛰 Skema provides a handy & composable way to validate / transform / purify the input data.

•    Javascript

---

Supports both async and sync flows. Skema has two working modes to support either async or sync validators, setters, etc, making it capable with much more complicated challenges. NOT only type checker. Unlike TypeScript, joi, and many others, Skema is not only a JavaScript type checker, but also a good solution for your Anti-Corruption Layer (ACL) to transform and purify the input data. And Skema could also be configured as a simple schema validator too.

yup - Dead simple Object schema validation

•    Javascript

---

Yup is a JavaScript object schema validator and object parser. The API and style is stolen heavily inspired by Joi, which is an amazing library but is generally too large and difficult to package for use in a browser. Yup is a leaner in the same spirit without some of the fancy features. You can use it on the server as well, but in that case you might as well just use Joi. Yup is also a good bit less opinionated than joi, allowing for custom transformations and async validation. It also allows "stacking" conditions via when for properties that depend on more than one other sibling or child property. Yup separates the parsing and validating functions into separate steps so it can be used to parse json separate from validating it, via the cast method.

TypeDB - A strongly-typed database

•    Java

---

TypeDB is a strongly-typed database with a rich and logical type system. TypeDB empowers you to tackle complex problems, and TypeQL is its query language. TypeDB allows you to model your domain based on logical and object-oriented principles. Composed of entity, relationship, and attribute types, as well as type hierarchies, roles, and rules, TypeDB allows you to think higher-level as opposed to join-tables, columns, documents, vertices, edges, and properties.

angular-schema-form - Generate forms from a JSON schema, with AngularJS!

•    Javascript

---

Schema Form is inspired by the nice [JSON Form](https://github.com/joshfire/jsonform) library andaims to be roughly compatible with it, especially its form definition. So what sets Schema Formapart from JSON Form?1. Schema Form integrates deeply with AngularJS and uses AngularJS conventions to handle forms.2. Schema Form uses [tv4](https://github.com/geraintluff/tv4) for validation, making it compatible with version 4 of the JSON schema standard.3. By default, Schema Form generates Bootstrap 3

JSV - A JavaScript implementation of an extendable, fully compliant JSON Schema validator.

•    Javascript

---

A JSON validator is a program that takes JSON data and, with a provided schema, will ensure that the provided JSON is structured in the way defined by the schema. This ensures that if validation has passed, the JSON instance is guaranteed to be in the expected format. It will also provide an explanation on why a particular instance failed validation. There is no one way to validate JSON, just like there is no one way to validate XML. Even the JSON Schema specification has gone through several revisions which are not 100% backwards compatible with each other. To solve the issue of using numerous schemas already written to older specifications, JSV provides customizable environments to validate your JSON within.

card-validator - Validate credit cards as users type.

•    Javascript

---

Credit Card Validator provides validation utilities for credit card data inputs. It is designed as a CommonJS module for use in Node.js, io.js, or the browser. It includes first class support for 'potential' validity so you can use it to present appropriate UI to your user as they type. A typical use case in a credit card form is to notify the user if the data they are entering is invalid. In a credit card field, entering “411” is not necessarily valid for submission, but it is still potentially valid. Conversely, if a user enters “41x” that value can no longer pass strict validation and you can provide a response immediately.

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.

jsonform - Build forms from JSON Schema

•    Javascript

---

The JSON Form library is a JavaScript client-side library that takes a structured data model defined using JSON Schema as input and returns a Bootstrap-friendly HTML form that matches the schema. The generated HTML form includes client-side validation logic that provides direct inline feedback to the user upon form submission (provided a JSON Schema validator is available). If values are valid, the JSON Form library uses submitted values to create the JavaScript data structure that matches the data model.

Coolstorage - ORM library for .NET

•    CSharp

---

The main strength of Vici CoolStorage is the ease of use. Most ORM tools still require a lot of unneeded code to accomplish basic data persistence tasks, but Vici CoolStorage is designed to relieve the programmer from these tedious and error-prone tasks, making it very intuitive to use.

ember-changeset - Ember.js flavored changesets, inspired by Ecto

•    Javascript

---

The idea behind a changeset is simple: it represents a set of valid changes to be applied onto any Object (Ember.Object, DS.Model, POJOs, etc). Each change is tested against an optional validation, and if valid, the change is stored and applied when executed. Given Ember's Data Down, Actions Up (DDAU) approach, a changeset is more appropriate compared to implicit 2 way bindings. Other validation libraries only validate a property after it is set on an Object, which means that your Object can enter an invalid state.

runtypes - Runtime validation for static types

•    TypeScript

---

Runtypes allow you to take values about which you have no assurances and check that they conform to some type A. This is done by means of composable type validators of primitives, literals, arrays, tuples, records, unions, intersections and more. If the object doesn't conform to the type specification, check will throw an exception.
