Zepgram Rest

Overview

Zepgram Rest is a technical module designed to streamline the development of REST API integrations in Magento 2 projects. Utilizing the Guzzle HTTP client for dependency injection, this module offers a robust set of features aimed at reducing boilerplate code, improving performance, and enhancing debugging capabilities. By centralizing REST API interactions and leveraging Magento's built-in systems, Zepgram Rest simplifies the implementation process for developers.

Features

Zepgram Rest provides several key features to aid Magento developers in creating and managing RESTful services:

• Avoid Code Duplication: Minimize repetitive code with a straightforward setup in di.xml. Implement your REST API integrations with just one class creation, streamlining the development process.
• Centralized Configuration: Manage all your REST web services configurations in one place, ensuring consistency and ease of maintenance.
• Built-in Registry and Cache: Take advantage of Magento's native cache mechanisms and dedicated registry to boost your API's performance and security. This feature helps in efficiently managing data retrieval and storage, reducing the load on your server.
• Generic Logger: Debugging is made effortless with an inclusive logging system. Enable the debug mode to log detailed information about your API calls, including parameters, requests, and responses, facilitating easier troubleshooting.
• Data Serialization: Declare whether your requests and results should be JSON serialized or not. This flexibility prevents the need for multiple serializer implementations, accommodating various API requirements with ease.

Installation

Guideline with ApiPool

1. Create a RequestAdapter class for your service extending abstract class Zepgram\Rest\Model\RequestAdapter, this class represent your service contract adapter:
   • public const SERVICE_ENDPOINT: define the service endpoint
   • dispatch(DataObject $rawData): initialize data that you will adapt to request the web service
   • getBody(): implement body request
   • getHeaders(): implement headers
   • getUri(): implement uri endpoint (used to handle dynamic values)
   • getCacheKey(): implement cache key for your specific request (you must define a unique key)
2. Create a system.xml, and a config.xml with a dedicated configName:
   • section: rest_api
   • group_id: $configName
   • fields:
     • base_uri
     • timeout
     • is_debug
     • cache_ttl
3. Declare your service in di.xml by implementing Zepgram\Rest\Service\ApiProvider as VirtualClass, you can configure it by following the ApiProviderConfig
4. Declare your RequestAdapter and ApiProvider in Zepgram\Rest\Service\ApiPoolInterface:
   • Add a new item in apiProviders[]:
     • The key is your custom RequestAdapter full namespace
     • The value is your ApiProvider as a VirtualClass
5. Inject ApiPoolInterface in the class that will consume your API and use $this->apiPool->execute(RequestAdapter::class, $rawData) where:
   • RequestAdapter::class represents the request adapter declared in apiProviders[]
   • $rawData is an array of dynamic data that will be dispatch in dispatch() method

Basic guideline implementation

Instead of declaring your class in Zepgram\Rest\Service\ApiPoolInterface you can also directly inject your ApiProvider in a dedicated class:

Configuration

Store config

If you do not declare specific configuration, the request will fall back on default configuration. To override the default config, you must follow this system config pattern: rest_api/%configName%/base_uri

XML config

You can configure your service with Zepgram\Rest\Service\ApiProvider by creating a VirtualClass and customize its injections for your needs by following the below configuration:

Implementation

Here is a simple implementation example with a service called Foxtrot using the order object as rawData:

FoxtrotOrderRequestAdapter.php

system.xml

config.xml

di.xml

OrderDataExample.php
