What to look for when you extend Magento with custom code or an extension

The Magento platform’s flexibility and scalability are its strengths. You have two options for customizing the Magento platform: you can use community-developed extensions available on the Magento Marketplace or build your own modules. While the Magento Marketplace makes it easy to add new themes and features, a custom module approach may be necessary in order to realize a specific vision. To save time and money, many merchants opt for a hybrid approach. They customise pre-built extensions to help them make informed decisions when expanding their store’s capabilities beyond the box.

MAGENTO INSTALLATION

When adding an extension or custom feature to Magento, there are many things to consider. Maintenance and development efforts can reduce the upfront cost. These problems can be avoided or minimized by selecting the right module and following Magento best practices.

FINDING THE RIGHT MODULE

Finding an extension that fits your business needs exactly can be difficult and may introduce labour cost for discovery/exploration/analysis of modules in the ecosystem. Although the Magento Marketplace is the best place to search for extensions, it’s possible to make concessions to ensure that you get as many modules as possible to meet your goals. To achieve the desired result, you may need to customize it further after you have chosen a module. Magento 2 allows you to customize the platform in many ways.

CUSTOMIZATION

Is the extension you are considering doing everything you expected? This might be true for today but business requirements may change and the extension may need to be modified to meet new requirements. It may be a good idea to create a custom module. Magento 2 can be improved in many ways, most notably:

plugins This feature, also known as interceptors allows you to intercept most public functions, alter arguments, output or override internal logic.

Observers– This can be used to trigger specific code in response to an event. You can create your own events, in addition to many already built-in events.

Dependency injection – Allows overriding and extending classes – and many more.

These and other techniques allow you to directly control third-party and core platform behaviours in order to achieve desired results.

PLATFORM VERSION MODIFICATIONS

It is impossible to predict how long a provider of module support will be available or whether a module’s relevance will change as your integrations evolve. This is the reality of software updates. It is recommended that customizations be tested in an environment before they are implemented. This will ensure that there are no code conflicts and that the functionality or performance of the upgrade does not suffer. When deciding to integrate with a module provider, it is important to evaluate their longevity and ability to provide support over the long-term. Verified providers can be found on the Magento Marketplace.

QUALITY ASSURANCE AND TESTING

It is not enough to add the extension and call it a day. Are you aware of all possible scenarios? Magento 2 module installation is very simple. However, testing can be costly. It’s well worth it. Knowing the details of how a module works in edge conditions and with different configurations will help you debug any potential problems down the road.

SUPPORT

Once you have uploaded your extension, the vendor might release a newer version that includes bug fixes or additional features. You may choose to upgrade depending on your requirements. It is easy to upgrade to a newer version of a Magento module using the Magento Marketplace. To see the Module Update Guide, click here.

Magento extensions are an integral part of any implementation. Magento has many extensions that can be used to enhance your experience. You will have the best control over your customers’ shopping experience by being able to modify their behavior or create your own module.
