Schemify

Use Ruby code to generate JSON schemas with intelligent defaults, validation, and versioning.

Install the gem and add to the application's Gemfile by executing:

bundle add schemify

If bundler is not being used to manage dependencies, install the gem by executing:

gem install schemify

More elegant usage will be added in the future. For now, a schema can be created using:

my_schema = Schemify::Schema.new do
  schema "https://json-schema.org/draft/2020-12/schema"
  id "https://example.com/product.schema.json"

  title "Product"
  description "A product from Acme's catalog"

  type "object"
  properties({
    "productId"   => {
      "description" => "The unique identifier for a product",
      "type"        => "integer",
    },
    "productName" => {
      "description" => "Name of the product",
      "type"        => "string",
    },
    "tags"        => {
      "description" => "Tags for the product",
      "type"        => "array",
      "items"       => {
        "type" => "string",
      },
      "minItems"    => 1,
      "uniqueItems" => true,
    },
  })
  required %w[productId productName price]
end

# Ruby hash representation of the schema
my_schema.to_h

# JSON representation of the schema
JSON.generate(my_schema.to_h)
