Create json schema with ease

Installation

composer require riley19280/fluent-json-schema

Basic Usage

use FluentJsonSchema\FluentSchema;

$schema = FluentSchema::make()
    ->type()->object()
    ->property('name', FluentSchema::make()
        ->type()->string()
    )
    ->return()
    ->compile();
/* Results in
{
    "type": "object",
    "properties": {
        "name": {
            "type": "string"
        }
    }
}
*/

More advanced usage can be found here. The entire meta-schema spec has been implemented using this package.

Contexts

There are several different "contexts" that you can be in while constructing json schema objects. These are the main data type contexts

• array
• integer
• number
• object
• string

Each of them have different methods that set specific properties related to that data type. If at any time you need to return to the "global" context, you can call the return method.

Boolean Schemas

In some cases, a schema that evaluates to true or false is needed, you can pass FluentSchema::make()->true() or FluentSchema::make()->false()

FluentSchema::make()
    ->type()->object()
    ->additionalProperties(FluentSchema::make()->false())

Converting to JSON

When done constructing your schema object, call the compile method on it. This will return a php array that you can then serialize to json.

By default, properties will be serialized in the order they are added to an object, i.e.

$schema = FluentSchema::make()->schema('schema')->id('id')->compile();
// Will be
// { "$schema": "schema", "$id": "id" }
$schema = FluentSchema::make()->id('id')->schema('schema')->compile();
// Will be
// { "$id": "id", "$schema": "schema" }

This can be changed by calling $schema->getSchemaDTO()->setKeyOrder(['$id', '$schema']). This will override the serialization order. Any unlisted keys will be added to the end.

Validation

Validation is done using the justinrainbow/json-schema package.

The following methods are available on the FluentSchema object to aid in schema validation:

• getSchemaStorage(): SchemaStorage
• setSchemaStorage(SchemaStorage $schemaStorage): static
• validate(mixed &$data, int $checkMode = null): Validator
• addValidationSchema(object|array $schema, string $id = null): static

$isValid = FluentSchema::make()
    ->type()->object()
    ->property('name', FluentSchema::make()
        ->type()->string()
    )
    ->return()
    ->validate((object)[
        'name' => 'validated!',
    ])
    ->isValid();

Please see the package documentation justinrainbow/json-schema for more detailed information on validation.
