Model

Libphpsky data model is fully generated from the AT Protocol definition. Let's take a look at the generation process.

Generation

Generated classes are located in the Aazsamir\Libphpsky\Model namespace.

Given the following AT Protocol definition:

{
  "lexicon": 1,
  "id": "com.atproto.identity.resolveHandle",
  "defs": {
    "main": {
      "type": "query",
      "description": "Resolves a handle (domain name) to a DID.",
      "parameters": {
        "type": "params",
        "required": ["handle"],
        "properties": {
          "handle": {
            "type": "string",
            "format": "handle",
            "description": "The handle to resolve."
          }
        }
      },
      "output": {
        "encoding": "application/json",
        "schema": {
          "type": "object",
          "required": ["did"],
          "properties": {
            "did": { "type": "string", "format": "did" }
          }
        }
      }
    }
  }
}

Let's look at the resulting class:

<?php

namespace Aazsamir\Libphpsky\Model\Com\Atproto\Identity\ResolveHandle;

/**
 * Resolves a handle (domain name) to a DID.
 * query
 */
class ResolveHandle implements \Aazsamir\Libphpsky\Action
{
    use \Aazsamir\Libphpsky\Generator\Prefab\IsQuery;

    public const NAME = 'main';
    public const ID = 'com.atproto.identity.resolveHandle';

    public static function id(): string
    {
        return self::ID;
    }

    public static function name(): string
    {
        return self::NAME;
    }

    public function query(string $handle): Output
    {
        return \Aazsamir\Libphpsky\Model\Com\Atproto\Identity\ResolveHandle\Output::fromArray($this->request($this->argsWithKeys(func_get_args())));
    }
}

First, id equals com.atproto.identity.resolveHandle.

It corresponds to the Aazsamir\Libphpsky\Model\Com\Atproto\Identity\ResolveHandle namespace.

By convention, the main object is the default method of lexicon, so the class is named ResolveHandle.

It is of type query, so generated class has a query method.

It has a single property handle, so the query method has a single parameter $handle with type string.

The output is an object with a single property did, so the query method returns an object called Output with a single property $did.

Meta client

ATProtoMetaClient is also fully generated, and aggregates all the methods from the AT Protocol.

Given previous example of com.atproto.identity.resolveHandle, the ATProtoMetaClient will have a method comAtprotoIdentityResolveHandle.

<?php

namespace Aazsamir\Libphpsky\Model\Meta;

class ATProtoMetaClient
{
    /**
     * Resolves a handle (domain name) to a DID.
     */
    public function comAtprotoIdentityResolveHandle(): \Aazsamir\Libphpsky\Model\Com\Atproto\Identity\ResolveHandle\Output {
        return new \Aazsamir\Libphpsky\Model\Com\Atproto\Identity\ResolveHandle\ResolveHandle($this->client, $this->token);
    }
    // ...
}

You can see, that it's only a convenient wrapper around all the generated classes.
