8 Steps to Integrate Magento 2 Extension Development with PWA Studio

Step 1: Configure Manifest File

PWA Studio extensions are structured as Node packages & require a package.json file. This file acts as the project manifest. It contains metadata like the name, entry point, and dependencies. While you can manually create this file, using the CLI commands is recommended. For example, yarn init or npm init. These commands initiate an interactive questionnaire to assist in generating your project metadata.

Step 2: Intercept and Declare Files

Extensions use intercept and declare files to interact with the extensibility framework. These files can be located anywhere within your project. But they must be referenced in the package.json file. For example, you can use pwa-studio.targets.intercept and pwa-studio.targets.declare paths.

Step 3: Create an Extension's API

Storefront developers use Targetables to modify extension behavior. Targets act as the official API for both modules and extensions. It allows other third-party extensions to intercept and utilize an extension's API.

Step 4: Declare a Target

You can use SyncWaterfall as the target type. This means that the interceptors for this target run synchronously. They pass their return values as arguments to subsequent interceptors.

Step 5: Define the API

The purpose of an extension's API is to provide functions. They perform specific code transformations within the extension. Use the tools provided by the extensibility framework. You can define this API in your project's intercept file.

Step 6: Access an Extension's API

Without modifications, the MyList component in your storefront would render an empty list. To add content, either a storefront project or a third-party extension can intercept. You can also utilize the myListContent target to call the API and add items to the list.

Step 7: Include Project Dependencies

If your extension needs third-party libraries, they should be added as peer dependencies. Peer dependencies ensure that the storefront project manages these packages. It prevents duplication in the final application bundle.package.json.

Step 8: Install and Test Locally

To test your extension on a local storefront, you can add it as a local dependency or list it as a build dependency.

i. Local dependency

Add this entry to your storefront project's package.json. This file allows you to set up a local path for your extension.

ii. Build dependency

Use the yarn link or npm link to link the extension globally. Then, add it to the BUILDBUS_DEPS_ADDITIONAL environment variable for your storefront project.

4 Steps to Configure Magento 2 Module Development

Step 1: Create a New Magento Module

Once your Magento instance is set up, you can proceed to create a new extension. Extensions are usually organized within modules in Magento. It includes defining the structure, configuration, & the code itself to implement new features. The general steps for this include:

1. Create the appropriate VendorName and ModuleName directories within the app/code folder.
2. Set up configuration files like module.xml & registration.php to initialize the module.
3. Set up routing by creating routes.xml and defining controller files. These are used to handle specific URL requests.
4. Create block classes to represent UI elements.
5. Define the logic for displaying information on the storefront.
6. Establish the view/frontend/templates and view/frontend/layout directories. They hold the layout and template files used by the module.
7. Run the following commands:

php bin/magento setup:di:compile: Compiles Magento classes and their dependencies.

php bin/magento cache:clean: Clears the cache while making changes to the extension.

Step 2: Package and Submit Your Extension Module

When your extension is complete and tested, you will need to package it for distribution. The extension can be shared via a module package in ZIP format. It can then be uploaded to the Magento Marketplace or made available via Composer.

The extension must comply with Magento's coding standards. Testing your extension will ensure a smooth review process by the Magento Marketplace.

Step 3: Disable Cache and Developer Mode

For an efficient development workflow, disable the Magento cache during development. You can do this from Admin -> System -> Cache Management. It’s also recommended to use developer mode. Make sure your Magento store is in developer mode so that all changes are reflected in real-time.

To check and extend the functionality, check the following code:

php bin/magento deploy:mode:set developer

Step 4: Deploy Your Extension

After developing the extension, use the following command to deploy it within Magento:

php bin/magento setup:upgrade

Note: This command ensures that your module is installed correctly and ready for use.

To verify the installation:

1. Navigate to Admin > Stores > Configuration > Advanced.
2. Check the list of active modules.
