Shopware 6 is an open-source eCommerce platform popular mainly in English-speaking countries. It is based on two equally well-known frameworks - Symfony and Vue.js. However, despite the “high-profile” technologies used in the development of this framework, not all developers manage to achieve full compliance with their project image using only what is given by default.

In this brief feature, we talk about solving this issue in an optimal way. Namely, by using a handy Shopware plugin.

Shopware 6 - Extend Service & Customize Your eCommerce Project

Shopware 6’s predecessor, Shopware 5, has already been downloaded over 800,000 times, and now its creators offer web developers something even more flexible, reliable, and convenient. Note that in the foundation of Shopware 6 lies the API-First concept, which means that this solution integrates with almost anything.

Thus, even though Shopware 6 features are already able to satisfy a lot of developer needs, you can easily connect third-party solutions to your project to make it even more customized. Below, we talk about one of the varieties of such integrations that helps Shopware extend service capacities you have using plugins.

Why Use Plugins in Shopware 6 & Extend Standard Interface?

In fact, Shopware 6 plugins provide an ideal solution for those web developers who have neither the time nor the desire to delve into the base code to “tailor” the platform to the individual project requirements.

Note also that the default Shopware 6 kernel comes with an integrated system of plugins (Symfony packages) that can be activated as needed. Thus, from a technical point of view, programmers are provided with the following options:

Now, let’s briefly consider the major types of plugins that can come in handy in your particular cases (all of them are available in the official store of plugins for Shopware).

Shopware SEO Plugin

Let’s start our Shopware 6 plugin review with perhaps the most popular category of plugins - plugins for SEO. They are needed to quickly improve the position of a web resource in search results and provide stable traffic. Such plugins analyze the existing website content, its markup, links, and many other attributes that affect the search ranking. 

In addition, some of them are “tailored” to specific search engines (for example, Google), helping to achieve exact compliance with their search results policies. View the full Shopware 6 plugin list for this category.

Shopware Newsletter Plugin

This type of plugins is most useful for those who want to optimize the process of sending corporate emails and better attract potential customers. With their help, you can set mailing schedules for each individual client, thereby avoiding sending messages to every other person.

Shopware Migration Plugin

This category of plugins allows you to quickly and painlessly carry out migration from any other platform to the Shopware platform. Typically, these plugins do not require developers to know the software code, so a seemingly difficult process of migration turns into a simple sequence of actions implemented using the GUI.

Shopware Blog Plugin

Most modern online stores contain a blog with articles in order not to lose their position at the top of search results. You can also add this block to your web solution in order to improve your SEO performance.

Shopware Backup Plugin

Creating a backup using plugins will allow you to ignore the technical issues associated with updating the platform. So, having pressed just a few buttons and manually setting a shortlist of parameters, you will update the framework without any risks and, if necessary, return everything as it was.

We’d also recommend paying attention to Shopware import plugins, Shopware debug plugins, and Shopware create plugins.

What to do with Plugins if the Platform Has Been Updated?

When updating the platform, a Shopware 6 developer needs to update plugins connected to the project as well to ensure end-to-end compatibility. You can find out which plugins correspond to Shopware 6 requirements and which don't in the Auto-Updater admin panel.

Shopware Plugin Update

Here’s a small Shopware plugin tutorial to help you cope with achieving the compatibility of previously installed plugins:

Shopware Plugin Development - How it Happens

At this stage, we offer to figure out how the interaction of plugins in Shopware 6 takes place and consider an abstract algorithm of creating a plugin. 

Step #1 - create a directory for a new plugin

In particular, you can open access to new, previously unconnected plugins through the /custom/plugins directory. Here, in fact, a separate directory is created for those plugins that you plan to use. 

Inside this directory, you must create the src directory (/custom/plugins/”plugindirectory”/src) where you need to allocate the base class of the plugin. All because through it, in fact, a plugin interacts with the platform. In order to optimize the directory structure, you will also need a .php file inside the src directory.

Step #2 - create a Composer

Each plugin is based on composer.json, and the connection of new plugins is done through the composer require. That is, if you are creating a plugin, you will have to start by creating composer.json in the plugin directory.

Here, you will need to specify parameters such as type, description, version, license, and the name of the developer. On top of that, you can specify additional metadata, such as copyright, tag, and icon.

Step #3 - create entities

Now, you can start describing entities in the src directory. Here, you will need to create an Entity child folder and put the file MyStorePluginEntity.php in it. The file should contain the software code that would describe entities. In turn, you will need to identify the dependencies in the container and put this all into practice (for example, the services.xml file should be in the Resources/config folder).

Step #4 - connect a plugin with database & create a controller

At this point, you will have to link your plugin to the database (if necessary) and create the controller MyStorePluginController.php in the src/Controller directory.

Voila! Now, you can interact with your freshly-implemented plugin via API and use it for your particular eCommerce purposes.
