What are the benefits of using SAP Spartacus or SAP Commerce Composable Storefront?


SAP Spartacus Timeline


SAP Spartacus or SAP Commerce Composable Storefront offers several benefits for both developers and business users, such as:


Extensibility- Developers can easily add, remove, or replace any feature or component in the storefront without affecting the core functionality. They can also leverage existing Angular libraries and tools to enhance the storefront. Moreover, they can use micro frontends to split the storefront into smaller and independent modules that can be developed and deployed separately.

Progressive Web App (PWA)- The storefront is designed to be a PWA, which means it can provide a fast, reliable, and engaging user experience across different devices and platforms. Users can access the Spartacus PWA storefront offline, receive push notifications, and install it on their home screens.


Server-Side Rendering (SSR)- It supports SSR, which means it can render the initial page on the server side before sending it to the browser. This can improve the performance, SEO, and accessibility of the storefront.


Internationalization (i18n)- The storefront supports i18n, which means it can display content in different languages and formats based on the user’s preferences and location. The storefront uses Angular i18n tools to handle translations, currencies, dates, numbers, and units.


Open Source Development- The Composable Storefront is open source and hosted on SAP GitHub Spartacus, which means developers can contribute to the SAP Spartacus development, report issues, request features, and access SAP documentation. The storefront also follows the Semantic Versioning (SemVer) convention to ensure compatibility and stability.


SEO optimization- The storefront supports SEO optimization, which means it can improve the visibility and ranking of the storefront in search engines. Spartacus uses Angular Universal to generate static HTML pages for each route, which can be crawled and indexed by search engines. The storefront also uses schema.org markup to provide structured data for each page, which can enhance the appearance and relevance of the storefront in search results.


Accessibility- SAP Spartacus supports accessibility, which means it can provide a user-friendly and inclusive experience for all users, regardless of their abilities or disabilities. It follows the Web Content Accessibility Guidelines (WCAG) 2.1 to ensure that the storefront is perceivable, operable, understandable, and robust. Spartacus also uses ARIA (Accessible Rich Internet Applications) attributes to provide semantic information for screen readers and other assistive technologies.


Versatility- Like other SAP tools, SAP Commerce Cloud, Composable Storefront is versatile and allows customization for various industries including automotive, consumer goods, medical, chemical, industrial equipment, and retail industries.


If you are using an accelerator-based storefront on SAP Commerce Cloud, it’s a good idea to migrate to SAP Commerce Cloud, Composable Storefront from the accelerator-based storefront to align with the latest e-commerce trends and reap the above benefits.
