class JSONSchema::Fluent

• JSONSchema::Fluent
• Reference
• Object

Overview

Contains methods for creating JSONSchema::Validator instances without interacting with the low-level domain objects. This class implements a DSL through block receivers rather than the standard method-chaining fluent API seen in json-schema libraries in other languages.

An instance of this class is available through JSONSchema.fluent.

require "jsonschema"

js = JSONSchema.fluent

validator = js.object do
  prop "first_name", (js.string do
    min_length 2
    max_length 64
  end)

  prop "last_name", (js.string do
    min_length 2
    max_length 64
  end)

  prop "email", js.string { format "email" }

  prop "address", (js.object do
    prop "street", js.string
    prop "city", js.string
    prop "state", js.string
    prop "zipcode", js.string
  end)

  prop "nicknames", (js.array do
    min_items 1
    items js.string
  end)
end

As in the example above, it's recommended to create a shorter variable that references JSONSchema.fluent. This will improve readability and can be customized to the needs of your code (rather than jsonschema exposing a global method with a short name).
