Magento 2 module is one of the largest open sources of e-commerce platform in the world. Its unique features and extensible code base have led many merchants with both large and small operations to use it in their projects. A module is a directory that has blocks, controllers, and model related to a specific business feature.
The following are rules required for building a high-end Magento 2 module.
-
Consider its complexity
To add attributes in Magento 2, you have to find out the development complexity of the module involved, because no estimation can be accurate. Checking the development complexity of the module is important because you might realize late in the development stage that you have to create more observers, plugins, models, checkout layout process, and even configuration files. To make sure you’re on the safer side, always use your time to investigate and plan development tasks to provide a precise estimation.
-
Estimate after Prototyping
Before starting the work, ensure you take your time to look into the code base, put it on paper using a pencil, and draw a diagram of custom module architecture. This diagram will give you a better idea of what needs to be implemented. Also, remember to check the Magento 2 code base to see extension points such as APIs and interfaces when coming up with custom functionality.
-
Use a Version Policy
Use of a versioning policy allows module stability before the release of a new version by Magento. In addition to this, checking into a composer package manager, and Search Suite Extension will help you specify and be updated on other packages plus the Magento 2 module. For clear explanations, it’s crucial to follow versions in a module or a package.
-
Be careful while following Magento 2 Core
Assuming that Magento 2 approaches are the same for all other modules will only mislead you and your Ecommerce Business since the Magento team has a variety of codes set aside for refactoring and reimplementation of it.
-
Provide a Definite Support Place
Before shipping your module to a Magento marketplace, make sure that you have localization support with you. All the texts assigned in the custom module should have a text function which can be used everywhere, e.g., in classes, email templates, JavaScript components, or even templates.
-
Use of a Composer File
A composer.json file consists of Magento 2 module, themes, localization, and packages with all dependencies’ listed. For instance, some Magento 2 has just one dependency listed which is “Magento/framework.” However, having a module that uses Magento or a catalog or API interfaces from Magento module catalog package cannot have a dependency for just a Framework. In addition, avoid the use of Helpers. These are special classes created by Magento 1 in which all functions and methods were located leading to too many responsibilities under one category.
Instead of using a Helper, it is best to create a smaller class with transparent naming and specific purposes in each. For instance, if you have an Attribute Helper class with two responsibilities, i.e., one for merging and another for mapping, consider having two independent classes with each having its responsibility. By doing this, you could come up with an AttributeMerger and an AttributeMapper separately. This will help you simplify and understand your work.
-
Use the Main Menu
When building a Magento 2 module, always ask yourself whether it does need the new menu item. The main menu is like a directory to a different department in your E-commerce Business. Custom modules require configuration settings, and a Magento does provide a particular page under its admin which leads you to the store where you can find the configuration menu. In case your module helps merchants increase conversion, then the term “marketing” can be a good name for your configuration section.
-
Carry out Module Testing with Different Deployment Modes
Before releasing the Magento 2 module into the Magento marketplace, make sure you take some time to plan to test with the production mode. This is important because its ecosystem requires a healthy and stable module. Also, make sure to switch in between product development application modes to be sure that the custom module does not end up breaking any existing functionality. Ensure its operational capability in all application modes.
-
Carry out Magento 2 Testing
While building a custom module for Magento 2, consider introducing different types of tests such as unit tests, functional tests, or integration tests. Make sure these tests are provided before releasing it into the marketplace since most people tend to look for these tests when reviewing. Tests make it easier to introduce new features as one is confidence in the functionality of the modules.
-
Code Review
Showing your code to other developers before giving it out to the marketplace and asking them to review it will provide you with a better and a much cleaner version of the code. Their opinions will help you know if your code is okay. This is important because one single mistake in your code or Search Suite Extension can lead to your website downtime and a decrease in your revenue as a store owner.
By following these simple yet effective rules, you will be in a much better position to come up with a high-quality Magento 2 module.
