JSON Schema Defaults

Extracting default value from JSON Schema.

Supports drafts from v.7 or its dialects. Extractor trusts that passed schema is valid, so perform external validation for it.

Installation

composer req sokil/php-json-schema-defaults

Usage

$schema = '{
    "$schema": "http://json-schema.org/draft-07/schema#",
    "type": "array", 
    "items": {"type": "string", "default": "hello"}
}';

$extractor = new Extractor();
$defaultValue = $extractor->extract($schema); // ["hello"]

Console command

To get default value from schema in console use next bin:

./vendor/bin/json-schema-defaults ~/path/to/schema.json
