PHPNomad Opis JSON Schema Integration
=====================================

[](#phpnomad-opis-json-schema-integration)

Concrete `JsonSchemaValidatorStrategy` implementation backed by [`opis/json-schema`](https://github.com/opis/json-schema). Drop in to satisfy [`phpnomad/json-schema`](https://github.com/phpnomad/json-schema) with full draft 2020-12 support.

Requirements
------------

[](#requirements)

PHP 8.2 or newer.

Installation
------------

[](#installation)

```
composer require phpnomad/opis-json-schema-integration
```

This pulls in both `phpnomad/json-schema` (the abstraction) and `opis/json-schema` (the concrete validator) automatically.

Usage
-----

[](#usage)

```
use PHPNomad\JsonSchema\Exceptions\ValidationError;
use PHPNomad\OpisJsonSchema\Integration\Strategies\OpisJsonSchemaValidator;

$validator = new OpisJsonSchemaValidator();

try {
    $validator->validate(
        ['name' => 'Alice', 'age' => 30],
        '/path/to/person.schema.json',
    );
} catch (ValidationError $e) {
    foreach ($e->failures as $failure) {
        printf(
            "%s: %s [%s]\n",
            $failure->path,
            $failure->message,
            $failure->keyword,
        );
    }
}
```

### Schema resolution

[](#schema-resolution)

The `$schemaUri` argument accepts:

- **A local file path** — the file is read and parsed as JSON before validation.
- **A URI string** — passed straight through to Opis's resolver. Register prefixes or IDs on the underlying `Opis\JsonSchema\Validator` beforehand if you need custom resolution.

### Custom Opis configuration

[](#custom-opis-configuration)

Subclass `OpisJsonSchemaValidator` and override the protected `buildValidator()` method to customize keyword registration, resolver prefixes, or other Opis behavior:

```
use Opis\JsonSchema\Validator as OpisValidator;
use PHPNomad\OpisJsonSchema\Integration\Strategies\OpisJsonSchemaValidator;

final class MySiteJsonSchemaValidator extends OpisJsonSchemaValidator
{
    protected function buildValidator(): OpisValidator
    {
        $validator = parent::buildValidator();
        $validator->resolver()->registerPrefix('https://my-site.example/', '/path/to/schemas');

        return $validator;
    }
}
```

The no-arg constructor keeps the class safe to auto-wire through standard dependency injection containers.

How failures are reported
-------------------------

[](#how-failures-are-reported)

Every Opis leaf error becomes a `PHPNomad\JsonSchema\ValidationFailure`:

- `path` — data pointer, dotted notation (e.g. `programs.gold.incentiveType`; empty string at the root).
- `message` — Opis's error message with placeholder substitution applied.
- `keyword` — the JSON Schema keyword that failed (`required`, `type`, `enum`, etc.).

Container errors (`allOf`, `oneOf`, `anyOf`) are unwrapped — only the leaf violations are surfaced, so callers see one entry per actual problem.
