## Spartacus and Composable Storefront
Hello and welcome!
This README is part of the `develop` branch, which is an active development branch in the Spartacus repository. As such, the following text may contain references to work that is in progress and not yet officially released.
Starting with version 5.0, “SAP Commerce Cloud, composable storefront” is the name for the official release of project “Spartacus” libraries published by SAP. The officially supported composable storefront is available to SAP Commerce Cloud customers. Documentation is available on the [SAP Help Portal](https://help.sap.com/docs/SAP_COMMERCE_COMPOSABLE_STOREFRONT?locale=en-US).
Starting with version 2211.19, composable storefront has aligned its versioning with SAP Commerce Cloud. The previous release of composable storefront was version 6.8. For more information, see [Changes to Release Numbering and Update Policies for Composable Storefront Starting in February 2024](https://help.sap.com/docs/SAP_COMMERCE_COMPOSABLE_STOREFRONT/6c7b98dbe68f4a508cac17a207182f4c/5fea969613a341308e2519c5f2827331.html?locale=en-US&version=2211)
Composable storefront is based off the Spartacus open source code, and is included in the SAP Commerce Cloud license at no extra cost. Composable storefront has a roll-forward update policy.
On-premise customers may still use Spartacus open source. For more information, see [Self-Publishing Spartacus Libraries Using the Open Source Code](docs/self-publishing-spartacus-libraries.md).
## What is Spartacus?
Spartacus is a lean, Angular-based JavaScript storefront for SAP Commerce Cloud. Spartacus talks to SAP Commerce Cloud exclusively through the Commerce REST API.

Spartacus is...
- **Extendable**: Spartacus is designed to be upgradable while maintaining full extendability. You'll be able to adopt new versions of Spartacus by updating the Spartacus libraries that we will regularly enhance. (In order to ensure that the first release is as extendable and upgradable as we'd like, breaking changes will very likely be introduced up until the 1.0 launch.)
- **Upgradable**: Spartacus code is published and used as libraries and follows semantic versioning conventions. By using the libraries, Spartacus is upgradable for minor and patch releases.
- **Progressive**: Spartacus is on a journey to be fully compliant with the Progressive Web Application (PWA) checklist. We aim to add support for all major features of a PWA-enabled storefront, to offer the best possible customer experience regardless of device or location.
- **Open Source**: Spartacus is open source. It will be continually developed by the SAP Commerce Cloud team, but we are very keen to welcome contributors and to foster an inclusive, active development community for Spartacus. See our [contributing documentation](CONTRIBUTING.md) for more information.
- **Modern**: The Spartacus storefront is part of our exciting new journey towards a customizable-yet-upgradable technology for SAP Commerce Cloud installations. See [SAP Customer Experience](https://cx.sap.com/en/products/commerce) for more information about SAP Commerce Cloud.

**Note:** Some Spartacus features require API endpoints that are only available in newer versions of SAP Commerce Cloud. For more information, see [Compatibility Matrix](https://help.sap.com/docs/SAP_COMMERCE_COMPOSABLE_STOREFRONT/6c7b98dbe68f4a508cac17a207182f4c/7f4265e58242466aba453632401cdff4.html) on the SAP Help Portal.
## Download and Installation
To get up and running with Spartacus, the recommended approach is to build your storefront application from ready-made libraries. You can also clone and build from source, but upgrading is not as simple.
Spartacus currently can only be used with a SAP Commerce Cloud instance through Commerce APIs.
To quickly add Spartacus libraries to an Angular application, you can use Spartacus schematics: `ng add @spartacus/schematics`. This will setup and install Spartacus libraries to your Angular project. Please check the [official Spartacus schematics documentation](https://help.sap.com/docs/SAP_COMMERCE_COMPOSABLE_STOREFRONT/cfcf687ce2544bba9799aa6c8314ecd0/e38d45609de04412920a7fc9c13d41e3.html) for all the prerequisites and instruction on how to use Spartacus schematics.
For complete setup instructions, see [Setting Up the Composable Storefront](https://help.sap.com/docs/SAP_COMMERCE_COMPOSABLE_STOREFRONT/cfcf687ce2544bba9799aa6c8314ecd0/ea187052be724bbf8796d1ba86131781.html) on the SAP Help Portal.
## Customizing and Extending Spartacus
To maintain our promise of upgradability, the design pattern for Spartacus is for non-core features to be built as feature libraries that add to or change the provided functionality.
When using Spartacus, you build an app that pulls in the Spartacus libraries, which contain the core resources needed to work with SAP Commerce. You then build new features that contain any custom functionality and pages.
Content for Spartacus pages is fetched from the SAP Commerce Cloud CMS (Content Management System), such as logos, links, banners and static pages. We recommend that new content-driven features follow the same pattern to enable Content Managers to modify page content through the CMS tools.
The documentation for customizing and extending Spartacus is still under development and is being released as it becomes available.

## Limitations
Spartacus is also being updated so that it works well with upcoming releases of SAP Commerce Cloud. This means that certain features of Spartacus may only work with unreleased future editions of SAP Commerce Cloud. This will be noted as we release new versions of Spartacus.
