Shopify APP Template in Symfony PHP 🐘

Authors: crissanclick , Interactiv4

A Shopify Symfony PHP skeleton to make your life easier and start your new APP faster.

This project skeleton is using Domain Driven Design (DDD) and Hexagonal Architecture (Ports & Adapters) to make it easier to understand and maintain.

It also uses the shopify/shopify-api package to make the Shopify API calls and it is based on the official Shopify PHP template replacing Laravel framework for a clean Symfony project.

👍 Benefits

Shopify apps are built on a variety of Shopify tools to create a great merchant experience.

The Symfony PHP app template comes with the following out-of-the-box functionality:

• OAuth: Installing the app and granting permissions
• Billing API: Charging merchants for using the app
• GraphQL Admin API: Querying or mutating Shopify admin data totally decoupled from the Shopify API
• Webhooks: Reacting to store events totally decoupled
• Shopify-specific tooling: (copied from the original template)
  • AppBridge
  • Polaris
  • Webhooks

🐳 Tech Stack

This project combines a number of third party open source tools:

• Symfony: https://symfony.com/ (PHP framework for backend)
• Vite builds the React frontend.
• React Router is used for routing. We wrap this with file-based routing.
• React Query queries the Admin API.
• i18next and related libraries are used to internationalize the frontend.
  • react-i18next is used for React-specific i18n functionality.
  • i18next-resources-to-backend is used to dynamically load app translations.
  • @formatjs/intl-localematcher is used to match the user locale with supported app locales.
  • @formatjs/intl-locale is used as a polyfill for Intl.Locale if necessary.
  • @formatjs/intl-pluralrules is used as a polyfill for Intl.PluralRules if necessary.

These third party tools are complemented by Shopify specific tools to ease app development:

• Shopify API library adds OAuth to the Symfony backend. This lets users install the app and grant scope permissions.
• App Bridge React adds authentication to API requests in the frontend and renders components outside of the embedded App’s iFrame.
• Polaris React is a powerful design system and component library that helps developers build high quality, consistent experiences for Shopify merchants.
• Custom hooks make authenticated requests to the GraphQL Admin API.
• File-based routing makes creating new pages easier.
• @shopify/i18next-shopify is a plugin for i18next that allows translation files to follow the same JSON schema used by Shopify app extensions and themes.

🚀 Getting Started

Requirements

1. You must create a Shopify partner account if you don’t have one.
2. You must create a store for testing if you don't have one, either a development store or a Shopify Plus sandbox store.
3. You must have PHP installed.
4. You must have Composer installed.
5. You must have Node.js installed.

🏗️ Creating my first app

1. Clone this repository.
2. In root folder run yarn install
3. Go to app folder and run composer install to install all backend the dependencies.
4. Then take the etc/databases/skeleton-app.sql and import it in your MySQL server
5. Go to apps/app/frontend folder and run yarn install or npm install to install all frontend the dependencies.
6. Then, execute a cp .env.example .env and fill the .env file with your Shopify APP credentials and decide if you want to charge something to use the APP, defining the interval and the required data.
7. Once you have all defined, you can run yarn dev or npm run dev to start the development server. (It will automatically raise the backend server and will map a real cloudflare domain against your localhost using the 8030 port)
8. It is important before click on button Install app inside the Shopify panel to update your .env file with the API_KEY_CLIENT and API_KEY_SECRET.
9. Congratulations! You already should have the APP working :)

How to register new webhooks

1. Create a new Handler class (Example. Crissanclick\App\Auth\Infrastructure\Shopify\Webhook\Handler\Uninstall)
2. Create a new Webhook class (Example. Crissanclick\App\Auth\Infrastructure\Shopify\Webhook\Uninstall)

3. Provide the webhook information in the Webhook class like:

   class Uninstall implements Webhook
   {
   public function __construct(private readonly UninstallHandler $handler)
   {
   }
   
   public function type(): string
   {
       return 'APP_UNINSTALLED';
   }
   
   public function handler(): WebhookHandler
   {
       return $this->handler;
   }
   }
