Ways to customize and extend Sitecore to meet specific requirements

Sitecore is a powerful and flexible .net-based content management system that allows organizations to build and manage websites and applications that meet their specific needs and requirements. One of the key benefits of Sitecore is the ability to customize and extend the platform to meet the holistic objectives of an organization, as well as the specific requirements for an individual application.

We'll look at how to customize and extend Sitecore, including understanding the Sitecore API, using plugins and modules, integrating Sitecore with other systems, and customizing Sitecore using code. We'll also look at best practices for customizing the underlying platform and provide examples of common integrations and platform customizations.

Understanding the Sitecore API

The Sitecore API (Application Programming Interface) is a set of tools and protocols that allow developers to interact with the platform and customize or extend its functionality. The Sitecore API can be used to perform a wide range of tasks, including creating and managing content, reporting on usage analytics, retrieving and updating data, and integrating with other systems.

There are two main types of API calls that can be used with Sitecore: web service calls and RESTful calls. Web service calls are used to perform tasks such as creating and managing content, while RESTful calls are used to retrieve and update data.

To use the Sitecore API effectively, it's important to choose the correct API version, follow best practices for coding and testing, and ensure that your code is optimized for performance. Making sure that your code works at scale, that your API calls are appropriately bundled, and that your calls are flexible enough to accommodate future requirements without requiring a full rewrite are all essential to customizing the underlying platform in a way that does not result in performance degradations that make the underlying platform essentially unusable.

Customizing Sitecore using plugins and modules

Another way to customize and extend Sitecore is by using plugins and modules. Plugins and modules are pre-built components that can be added to a Sitecore website or application to add new functionality or improve existing functionality.

There are many different types of plugins and modules available for Sitecore, including those that add new features or integrations, improve performance, or enhance the user experience. To find and install plugins and modules, you can use the Sitecore Marketplace or other online repositories.

It's important to carefully test and deploy any plugins that you include in your application to ensure that they don't introduce any defects or security vulnerabilities. It's also important to consider the potential risks and drawbacks, including compatibility issues and the risk of vendor lock-in.

One common use of Sitecore plugins is an integration between Sitecore and Salesforce. The plugin is Sitecore-supported functionality, allowing the project team to rest easy with respect to long-term support and upgradability. This integration allows organizations to manage customer data and interactions more effectively, improving the customer experience by ensuring preferences and past interactions are taken into consideration when presenting the user with content, and increasing sales conversions.

Integrating Sitecore with other systems

Integrating Sitecore with other systems is another way to customize and extend it to meet the specific needs of an organization. This can include integrating with CRM systems as discussed above, e-commerce platforms, social media, backend inventory systems, or even custom applications.

There are several approaches to integrating Sitecore with other systems, including using the Sitecore API, using third-party tools and plugins, or building custom integration solutions. When planning and implementing an integration, it's important to choose the right approach, test the integration before deploying it, and consider the potential challenges and best practices for integrating Sitecore with other systems.

Of all the integration approaches available, the “build your own” should always be the last approach considered. This path forces you to take control of the integration maintenance, own any changes that come with Sitecore changes as the platform evolves in future versions, and also worry about patching as security concerns are identified. Using the Sitecore API, or 3rd-party plugins, alleviate many of those concerns and allow you to offload the maintenance and patching to the vendor (whether Sitecore itself or a 3rd-party vendor) and allow your team to focus on building your application.

Customizing Sitecore using code

Customizing Sitecore using code is another way to extend and improve its functionality. This can include customizing pipelines, events, templates, and other components of the Sitecore platform. As a .net application that allows for almost anything to be overridden, replaced, or extended, Sitecore is one of the most extensible enterprise CMS applications on the market. Additionally, given the common availability of .net developers, writing code to alter the platform’s behavior to fit your application’s specific requirements has never been easier.

However, with great power comes great responsibility! Always keep in mind that by customizing the underlying platform, you’re jeopardizing your future upgrade path, and also forcing your team to own future maintenance and security vulnerabilities.

To customize the underlying Sitecore platform using code, it's important to plan and implement your customizations carefully, follow best practices for coding and testing, and ensure that your code is optimized for performance. It's also important to consider the potential challenges and best practices for customizing Sitecore using code.

Some of these challenges are mentioned above, but deserve being reiterated: Always preserve your upgrade path. Before deciding that you want to create a bi-directional item provider, or change the behavior of the content manager to alleviate the screams from your content management team, or change the structure of the launchpad to present as seven red balloons (two drawn with blue ink), remember: any changes you make to the way the platform behaves will almost certainly not seamlessly upgrade, and your team will be on the hook for shoehorning your super-essential customization into the future version. Is your customization really necessary? In my experience, they rarely are, and an alternative can usually be found using OOTB features that get you most of what you want, while also preserving your upgrade path.

For projects that do choose to customize the platform, most common customizations are custom field types, custom analytics, custom xDB facets, and custom user profiles. All of these are typically fairly safe when considering your future upgrade path. Deeper customizations such as (mentioned above) bi-directional item providers are typically best left on the cutting room floor, as they will be expensive to implement, difficult to fully test, and next-to-impossible to upgrade.

• Plan and test your customization or extension carefully : Before implementing an extension of the platform - or worse, a customization of how the core plafform functions -, it's important to thoroughly plan and test it to ensure that it meets your needs and doesn't introduce any issues. Understand the requirements fully, and ensure that you can’t achieve those requirements using OOTB functionality, and if not, make sure you have fully flushed out user stories to ensure you have defined success and enabled your testing team to create test cases that not only test your functionality, but also test for defects you may introduce elsewhere in the platform.
• Optimize performance : Customizing the platform can impact the performance of your Sitecore website or application, so it's important to optimize your code for performance and monitor the impact of your customization or extension on performance. Additionally, consider the scalability of your customization. Ensure any API calls are appropriately structured to reduce the number of calls to the bare minimum that are required.
• Follow security best practices : Customizations and extensions can also introduce security risks, so it's important to follow best practices for secure coding and testing to ensure that your customization or extension doesn't introduce any vulnerabilities.
• Follow Sitecore's guidelines and best practices: Sitecore has published guidelines and best practices for customizing and extending its platform, so it's important to follow these guidelines to ensure that your customization or extension is successful and meets Sitecore's standards.
• Consider the long-term maintenance and support of your customization : Both customizations and extensions require ongoing maintenance and support, so it's important to consider the long-term implications of your customization or extension and ensure that you have the resources and expertise to maintain and support it over time.
