Description

Allows parsing data of various structures, meaning the population and validation of data into a defined structure. For example, converting an API request into a Data Transfer Object (DTO).

Heavily inspired by the well-known TypeScript library zod.

Requirements

  • php: ^8.1

Installation

Through Composer as chubbyphp/chubbyphp-parsing.

composer require chubbyphp/chubbyphp-parsing "^1.1"

Usage

use Chubbyphp\Parsing\Schema\SchemaInterface;

/** @var SchemaInterface $schema */
$schema = ...;

$schema->nullable();
$schema->preParse(static fn ($input) => $input);
$schema->postParse(static fn (string $output) => $output);
$schema->parse('test');
$schema->safeParse('test');
$schema->catch(static fn (string $output, ParserErrorException $e) => $output);

array

use Chubbyphp\Parsing\Parser;

$p = new Parser();

$schema = $p->array($p->int());

$data = $schema->parse([1, 2, 3, 4, 5]);

// validations
$schema->length(5);
$schema->minLength(5);
$schema->maxLength(5);
$schema->includes(5);

// transformations
$schema->filter(static fn (int $value) => 0 === $value % 2);
$schema->map(static fn (int $value) => $value * 2);
$schema->sort();
$schema->sort(static fn (int $a, int $b) => $b - $a);

// conversions
$schema->reduce(static fn (int $sum, int $current) => $sum + $current, 0);
