README

This project provides a composer package with a JSON schema validator, building on top of justinrainbow/json-schema.

Installation

Run

composer require ergebnis/json-schema-validator

Usage

If you have used the validator from justinrainbow/json-schema before, you might have observed that it has a few flaws:

• The validator is stateful.
• The validator requires decoding JSON strings before validating them.
• The validator returns an array of errors, where each error is an array.

This package delegates the validation to justinrainbow/json-schema and provides a friendlier interface.

<?php

declare(strict_types=1);

use Ergebnis\Json\Json;
use Ergebnis\Json\Pointer;
use Ergebnis\Json\SchemaValidator;

$json = Json::fromFile('composer.json');
$schema = Json::fromString(file_get_contents('https://getcomposer.org/schema.json'));
$jsonPointer = Pointer\JsonPointer::document();

$schemaValidator = new SchemaValidator\SchemaValidator();

$result = $schemaValidator->validate(
    $json,
    $schema,
    $jsonPointer
);

var_dump($result->isValid()); // bool
var_dump($result->errors());  // flat list of `ValidationError` value objects
