The document discusses the history and current state of e-commerce modules for the Silverstripe CMS. It outlines four main e-commerce modules - Silverstripe Shop, SwipeStripe, Silvercart, and Silverstripe E-commerce. Each module has different features and authorship. The document also discusses challenges in developing e-commerce applications and features of the Silverstripe E-commerce module, including its flexible data structure and product, cart, checkout, and post-sale features. Coding challenges and areas for potential Silverstripe improvements are also outlined.

1. Silverstripe & E-commerce

2. History
● Originally started by Silverstripe Ltd at least five
years ago – abandoned due to lack of
community buy-in
● Payment module continued to be developed
by Silvertripe (and now part of GSOC)
● Since then, developed by Nicolaas and Jeremy,
Jeremy later starting his own module: shop
● Silvercart and SwipeStripe are more recent e-
commerce modules.

3. Today
● Four über-developed modules, including
demo sites, installers, tests, in-depth
documentation
● Do you see this level of development in
any of the other modules ?
● Lots of developers (and their clients) are keen
to be develop e-commerce applications
● Are they confused by the options?
● Do they use Magento or other applications
rather than Silverstripe ones?

4. Modules out there

5. Silverstripe Shop
● Author: Jeremy Shipman
● Excellent documentation
● Best practice release process
● Quality tests through TravisCI
● Code simplicity as well as strong usage of
Silverstripe core code base and Best
Practice
● http://ss-shop.org/

6. SwipeStripe
● Author: Frank Mullenger
● Lots of tests
● Innovative CMS features
● Xero integration
● Virtual products
● Small licensing fee
● 3.0 ready!
● http://www.swipestripe.com/

7. SilverCart
● Author: Roland Lehmann et al.
● Probably most polished documentation and out-of-
the-box solution
● Does not use the original e-commerce as code base
● Master-Slave product relationships
● product variations can be grouped while the
variations can be independently maintained
● PDF invoices
● Most usage of third-party tools (e.g.
DataObjectManager, the YAML CSS framework) and
most intrusive (e.g. Page extends SilvercartPage)
● http://www.silvercart.org/

8. select an e-commerce module
● What features do I need?
● What is the smallest code base to achieve this
● The bigger the code base, the more to
develop / test / maintain
● Documentation
● Tests
● DYI vs Pre-Baked
● Can I get help? How much will it cost?

9. E-commerce is Zpeshial

10. E-commerce is zpeshial 1
● My experience: all parties underestimate the work
involved
● Site owner:
● entering / importing products: Images, pricing,
descriptions, product grouping, variations
● Policies and business processes: delivery costs, tax,
cancellations, customer communication
● Designer: the amount of screens to design
● You can save a lot of time by standardising forms, etc...
but many web designers are not very good at this.
● Front-end developer: interaction required
● Ajax stuff, difficult forms, products and product category
pages work with few or many – definitely diverse -
products

11. E-commerce is zpeshial 2
● Back-end developer:
● this is more an application than a website
● Keep a record of transactions (e.g.
address of the member at time of order –
not just today)
● Many tricky relationships and coding
challenges
● Discounts, delivery, tax, etc... etc...
● You have to be precise otherwise end
customers get upset (websites can be
more loosely coded)

12. Silverstripe E-commerce Module

13. Silverstripe E-commerce

21. YAML example

23. Settings review

24. Coding challenges in e-commerce
● Versioning / rules about ● Keep code flexible enough
changing data to work with many
requirements
● canCreate, canEdit,
canDelete are carefully ● Add lots of “hooks”
defined ● Allow class replacement
● Keep version number ● e.g. Order = new
relating to sales $MyOrderClassName
● Referential integrity ● Many objects relationship
● can we delete a product? ● BAD: one Order HasMany
● “De-normalisation” Products

price in old orders for this
product HasMany “Buyables”
● Save ClassName + ID (+
Version)

Field

25. Silverstripe improvements needed
● ModelAdmin: better presentation and easier to
