Return results as ValidationRecords

This release alters the data structure returned by [[Validator]].validate. validate now returns an immutable record type.

type ValidationRecord = {
    isValid: boolean,
    messages: Set<string>,
    rules: Map<string, ValidationRecord>
}

ValidationRecord is recursive, which makes it easier to traverse.

The rules field makes deep traversals a little unwieldy. [[ValidationRecord]].refine(path: Array<string>) provides a convenient method for getting arbitrarily-nested results while excluding verbose parts of the key path. (See #3 for an example)

v0.6.0

This release reconfigures the build process to support distribution via npm. UMD scripts are still committed to the /dist folder.

v0.5.0

When using the fluent interface to describe rulesets, each call to validator.ruleFor or validator.ruleForEach will return a new Validator instance. Validator rulesets are now immutable if you use the method interface.

v0.4.1

Fixes the naive implementation of the required predicate:

• Whitespace fails validation
• NaN fails validation
• Reference types, null and undefined fail validation

v0.4.0

• Renames facts export to predicates
• Adds ruleForEach method to instances of Validator, to support validating collections of items
• Adds Validator.which static constructor to support dynamically picking a validator each time validate() is called

v0.0.2

Update compiled files in the dist directory

v0.0.1

Initial version of codebase
