Vod - PHP Validation and Object Definition Library

Vod is a powerful PHP library for validating and defining object structures. It provides a fluent API for creating schemas, parsing data, and generating TypeScript definitions and JSON schemas.

Installation

You can install Vod via Composer:

composer require vod/vod

Testing

composer test

Usage

Basic Schema Creation

To create a schema, use the v() function to access the Vod API:

use function Vod\Vod\v;
$schema = v()->object([
    'name' => v()->string(),
    'age' => v()->number()->int(),
    'email' => v()->string()->optional(),
]);

Parsing Data

You can parse data against your schema:

$data = ['name' => 'John', 'age' => 30];
$result = $schema->parse($data);

Available Types

Vod supports various types:

v()->string(): String type
v()->number(): Number type (can be further specified as int() or float())
v()->boolean(): Boolean type
v()->array(): Array type
v()->object(): Object type
v()->enum(): Enum type
v()->any(): Any type
v()->date(): Date type
v()->tuple(): Tuple type
v()->union(): Union type
v()->anyOf(): Alias of Union type
v()->intersection(): Intersection type
v()->all(): Alias of Intersection type

Optional Fields

Make fields optional:

v()->string()->optional()

Default Values

Set default values:

v()->string()->default('default value')

Note that default values are only used currently if the field is not provided data AND is optional.

Using Rules

If you are using inside of Laravel, you can use the rules method to add rules to your schema. This relies on the Laravel Validator facade, so will only work if it is available.

  v()->string()->rules('email')->parse('not an email') // throws an exception
  v()->string()->rules('email')->parse('[email protected]') // returns [email protected]

Adding and referencing definitions

Add definitions to your schema for reusable components:

$schema = v()->object([
    'user' => v()->ref('userSchema'),
    'posts' => v()->array(v()->ref('postSchema')),
])
->define('userSchema', v()->object([
    'id' => v()->number()->int(),
    'name' => v()->string(),
    'email' => v()->string(),
]))
->define('postSchema', v()->object([
    'id' => v()->number()->int(),
    'title' => v()->string(),
    'content' => v()->string(),
]));

To add a reference to a defined schema, use v()->ref('schemaName').

Note: Definitions can only be added to a top-level object schema. They are not available for nested objects or other types.

Using definitions can help you create more modular and reusable schemas, especially for complex data structures.

Generating TypeScript Definitions

Generate TypeScript definitions:

$typescript = $schema->toTypescript();

Generating JSON Schemas

Generate JSON schemas:

$jsonSchema = $schema->toJsonSchema();

Adding Descriptions

Add descriptions to your schema for better documentation - this is only used in json schemas currently.

$schema = v()->object([
        'name' => v()->string()->description('The user\'s full name'),
        'age' => v()->number()->int()->description('The user\'s age in years'),
])->description('User information schema');
