js-ps

Convert JSON schema to Prismatic/Plumatic schema. Supports complex types and arbitrary levels of nesting.

Usage

Add to your lein dependencies:

Convert a JSON schema:

(ns foo
  (:require [js-ps.core :refer [->prismatic]]
            [schema.core :as s]))

(def json-schema
  {:type "object"
   :properties {:a {:type "string"}
                :b {:type "integer"}
                :c {:type "array"
                    :items {:type "boolean"}}}})

(def prismatic-schema
  (->prismatic json-schema)

You can use local refs in your schema, these are assumed to be resolvable in the given schema:

(def json-schema
  {:type "object"
   :properties {:a {"$ref" "#/definitions/a"}}
   :definitions {:a {:type "string"}}})

(def prismatic-schema
  (->prismatic json-schema)

alternatively, you can pass a parent document against which refs will be resolved:

(def json-schema
  {:type "object"
   :properties {:a {"$ref" "#/definitions/a"}}})

(def document
  {:definitions {:a {:type "string"}}})

(def prismatic-schema
  (->prismatic json-schema document)

Feature support

This is largely for use with ring-swagger so support for JSON schema features is not intended to be exhaustive. The supported schema rules include:

• additionalProperties
• description
• enum
• items (but not tuples)
• oneOf
• properties
• required
• type (but not union types)
• $ref (but only local refs, by path)
