ValidateSchema

Validates data against a JSON Schema and returns any errors.

Signature

ValidateSchema(any data, object schema)

Parameters

• data (any): The value to validate.
• schema (object): A JSON Schema definition as a Jyro object.

Returns

• array: An array of error objects. Empty array if the data is valid.

Each error object has:

• path (string): The JSON Pointer path to the failing element.
• keyword (string): The schema keyword that failed (e.g., "type", "required").
• message (string): A description of the failure.

Description

Serialises both the data and schema to JSON, then evaluates using the JsonSchema.Net library with list output format to collect all errors. Supports JSON Schema draft 2020-12 features including type constraints, required properties, patterns, min/max values, and nested schemas. Returns an empty array when the data is valid.

Examples

var schema = {
    "type": "object",
    "properties": {
        "name": { "type": "string" },
        "age": { "type": "number", "minimum": 0 }
    },
    "required": ["name", "age"]
}

var errors = ValidateSchema({ "age": -5 }, schema)
# errors = [
#   { "path": "", "keyword": "required", "message": "..." },
#   { "path": "/age", "keyword": "minimum", "message": "..." }
# ]

var noErrors = ValidateSchema({ "name": "Alice", "age": 30 }, schema)
# noErrors = []

# Check validity
if Length(errors) == 0 then
    Data.valid = true
end
