README

This document provides an overview of the GardenLawn Delivery module, focusing on the distance calculation and shipping carrier implementations.

Directory Structure

• Helper: Contains configuration helpers.
• Model/Carrier: Contains shipping carrier implementations.
• Service: Contains service classes for distance calculation.
• ViewModel: Contains view models for frontend interaction.

Files Overview

1. Helper/Config.php

This helper class provides methods to retrieve module configuration values from the Magento system configuration.

Key Constants:

• XML_PATH_ENABLED: 'delivery/general/enabled'
• XML_PATH_WAREHOUSE_ORIGIN: 'delivery/general/warehouse_origin'
• XML_PATH_PROVIDER: 'delivery/api_provider/provider'
• XML_PATH_GOOGLE_API_KEY: 'delivery/api_provider/google_maps_api_key'
• XML_PATH_HERE_API_KEY: 'delivery/api_provider/here_api_key'
• Truck settings constants (height, width, length, weight, etc.)

Key Methods:

• isEnabled($storeId = null): Checks if the module is enabled.
• getWarehouseOrigin($storeId = null): Retrieves the warehouse origin address.
• getProvider($storeId = null): Retrieves the configured API provider (Google or HERE).
• getGoogleApiKey($storeId = null): Retrieves the Google Maps API key.
• getHereApiKey($storeId = null): Retrieves the HERE API key.
• getTruckParameters($storeId = null): Retrieves an array of truck parameters for HERE API.

2. Model/Carrier/DistanceShipping.php

This class implements the "Distance Shipping" carrier method. It calculates shipping costs based on the distance between the warehouse and the customer's address, potentially including intermediate points.

Key Features:

• Uses DistanceService to calculate distances.
• Supports multi-point routes via getDistanceForConfigWithPoints.
• Calculates price based on a configured prices table (prices_table).
• Supports a target SKU (target_sku) for specific product shipping logic.
• Calculates price based on quantity (m2), palette count, and base kilometers.

Key Methods:

• collectRates(RateRequest $request): The main method for calculating shipping rates.
• getDistanceForConfig($address): Calculates distance from origin to address.
• getDistanceForConfigWithPoints($address): Calculates distance including intermediate points defined in config.

3. Model/Carrier/CourierWithElevatorShipping.php

This class implements the "Courier with Elevator Shipping" carrier method. It calculates shipping costs based on distance and load factors.

Key Features:

• Uses DistanceService to calculate distance from warehouse to customer.
• Calculates price based on price per km (price), load factors (factor_min, factor_max), and maximum load (max_load).
• Targets specific SKUs (target_sku).

Key Methods:

• collectRates(RateRequest $request): Calculates the shipping rate based on distance and load logic.

4. Service/DistanceService.php

This service class is responsible for calculating distances using external APIs (Google Maps or HERE).

Key Features:

• Supports switching between Google Maps and HERE Technologies via configuration.
• Implements getDistance($origin, $destination) as the main entry point.
• getDistanceFromGoogle: Uses Google Distance Matrix API.
• getDistanceFromHere: Uses HERE Routing API v8.
• geocodeAddress: Geocodes addresses using HERE Geocoding API (required for HERE Routing).
• buildTruckParameters: Constructs truck-specific parameters for HERE API requests.
• getDistanceForPoints: Calculates total distance for a sequence of points.

5. ViewModel/DistanceCalculator.php

This ViewModel is likely used in frontend templates to display distance information or calculate delivery times.

Key Features:

• Uses Config helper and Curl client.
• getDistance($origin, $destination): Returns distance and duration data, supporting both Google and HERE providers.
• getHereDistance: Specific implementation for HERE API, including truck parameters and detailed response parsing (distance text, duration text, arrival time).
• getGoogleDistance: Specific implementation for Google API.
• getHereCoordinates: Helper to geocode addresses for HERE API.

Configuration

The module is configured via Stores > Configuration > GardenLawn > Delivery Settings.

Key Configuration Sections:

• General Configuration: Enable/disable module, set warehouse origin.
• API Provider: Select provider (Google/HERE) and set API keys.
• Truck Parameters (HERE API): Configure vehicle dimensions, weight, type, hazardous goods, and features to avoid.
• Delivery Methods: Configure specific settings for DistanceShipping and CourierWithElevatorShipping (enabled, title, prices table, etc.).
