5. The Challenge Why would you ever want to build an eCommerce store in 24 hours?
6. To be fair, we have done eCommerce before seriously. a lot.
7. The Challenge: Pure madness ▪ Build a transactional-site in 24 hours ▪ Server Agnostic (run on Tomcat and WAS) ▪ Must be able to process orders ▪ Manageable inventory ▪ Responsive Design (RWD)
8. The Challenge: A transactional-site in 24 hours ▪ Communication is the key ▪ Everyone must ask questions and discuss solutions ▪ Otherwise, failure is your only possible outcome
9. The Challenge: Server Agnostic Develop and build using a local Tomcat installation, run the app anywhere ▪ IBM WAS ▪ JBoss ▪ Glassfish
10. The Challenge: Must be able to process orders ▪ Connect with an order system (AS400, SAP, etc) ▪ SOAP service for order creation
11. The Challenge: Manageable inventory With the store being the online representation of a physical location, there is a set number of items or products available and the list needs to be updated to match sales made at the physical store ▪ Inventory/stock adjustment ▪ Price adjustment
12. The Challenge: Responsive Design (RWD) ▪ No matter the device, a user needs to be able to view products as well as complete a purchase ▪ We used “base” (https://github.com/dutsonpa/base) as our RWD starting template and made slight modifications to match a brochure that was emailed to potential customers ▪ We used a fluid layout that would break into columns to take advantage of available screen space and allow us to to stack information together on a single category page
13. Road Map After getting the requirements, here is our plan to success
14. ▪ Identify the objects ▪ Create a way to manage the system ▪ Pick and implement the tools needed for the job Road Map: Plan
15. Road Map: Identify the Objects Site Flow ▪ Home ▪ Category ▪ Payment Information ▪ Completion Products ▪ Inventory ▪ Price
16. Road Map: Admin Tool ▪ Add and edit products ▪ Add and edit categories ▪ Set product prices ▪ Set product availability ▪ App security - host on a restricted domain ▪ Database access
17. Tools
18. Tools: Spring MVC
19. Tools: Spring used in JSP
20. Tools: Spring Security HTTPS everywhere ▪ Once unsecure, always unsecure You may think that going secure from the beginning is going to slow your site down due to encapsulation of files and TCP SSL negotiation, this would normally be the case, however once you are end-to-end secure you can harness the power of SPDY ( http://www.chromium. org/spdy/spdy-whitepaper) to minimize round-trip time as well as enable header-compression and multi-domain requests ▪ SPDY was donated by Google to the Apache Foundation (https://svn.apache. org/viewvc/httpd/mod_spdy/trunk/) ▪ SPDY is also available for Nginx (http://nginx.org/en/docs/http/ngx_http_spdy_module.html)
21. Tools: Security configuration
22. Tools: Mongo Benefits of NoSQL ▪ Speed ▪ Flexible ▪ Data Cluster Considerations that must be taken with NoSQL ▪ Speed - Indexing is still something you need to do ▪ Flexible - just because you can doesn’t mean you should
23. Tools: Mongo Configuration
24. Tools: Jackson ▪ Partial REST API ▪ Hand off of data from back to front ▪ Easy Integration into the project ▪ Download at https://github.com/FasterXML/jackson ▪ Insert .jar files into lib ▪ Annotate methods
25. Tools: Credit Card Processing Hand off of the CC: ▪ PCI Compliance (https://www.pcisecuritystandards.org/) ▪ Tokenization to protect your customers and yourself when you get hacked ▪ PayPal, Amazon, Google Wallet, other third-party provider
26. You’ve probably worked with this project manager too... Requirement Changes
27. Requirement Changes: Change request during the build Add donations ▪ Not a standard product ▪ Customer Assigned value ▪ Return receipt is a tax document Treat the store like a brick and mortar ▪ Open and close times
28. Requirement Changes: Donations
29. Requirement Changes: Open/Close DelegatingFilterProxy
30. Open/Close Filter
31. The Past and the Futurious Yeah, Phil probably shouldn’t write any more puns
32. The Past…: What we didn’t do We did not do the following: ▪ Test driven design/development ▪ Spring Boot ▪ Spring Data ▪ Maven / Gradle ▪ Ant ▪ Spring Security instead of the Open/Close filter
33. ...and the Futurious: What next? We built another eCommerce site: https://shop.ifit.com/ ▪ Built in 8 days (spanning a holiday) from the charity base ▪ Used Handlebars (http://handlebarsjs.com/) for content management ▪ Fleshed out the REST API with robust product, category, and order calls ▪ Added a template engine (we like SiteMesh - https://github.com/sitemesh)
