SenchaCon 2016 - How to Auto Generate a Back-end in Minutes
Download as PPTX, PDF1 like59 views
The document discusses how to quickly auto-generate back-end services using Speedment's Ext Speeder, which allows developers to efficiently create REST API endpoints from existing databases with minimal code. It highlights the advantages of this approach, including reduced implementation time and improved performance with in-memory data handling, achieving low latency and high transaction rates. Additionally, it provides information on the background of the founders, deployment scenarios, and available support options.

- 1. How to Auto Generate a Back- end in Minutes Per Minborg & Emil Forslund, Speedment, Inc.November 9, 2016
- 2. Every Decision a Developer Makes is a Trade-off “The best code is no code at all”
- 3. Using Code Generation • Makes the code efficient and short • Modifications are done once and applied everywhere • Minimizes errors • “DRY” (Don’t Repeat Yourself) vs. ”WET” (We Enjoy Typing) • “Code your code”
- 4. About Us Per Minborg • Founder of several IT companies • Lives in Palo Alto • 20 years of Java experience • 15+ US patents • Blog: Minborg’s Java Pot Emil Forslund • Back-End Developer • Lives in Palo Alto • 8 years of Java experience • Blog: Age of Java
- 5. Ext Speeder Front End Back End One End
- 6. Ext Speeder • Existing Relational Database • Graphically Setup REST API Endpoints • Generate Complete Back-End • Deploy Stand-Alone or on a Java EE Application Server • Merge Changes in DB Schema into Application Ext JS Application
- 7. API Management • Define Exactly Which Data to Expose • Rename tables, columns, etc. • Create Custom HTTP Paths • Change Data Format • Create Virtual Columns
- 8. Generated Runtime • Column Oriented In-Memory Cache • Automatic Reload From Database • Multi-Threaded Execution • JSON Encoding • Secure Socket Layer (SSL) curl –X GET https://api.example.com/customers ?start=1000 &limit=25 &callback=cb cb([ {"id":1, "name":"Speedment, Inc.", "region":"North America"}, {"id":2, "name":"Sencha, Inc.", "region":"North America"}, ... ]);

- 11. Sales Organization DB – What We Have • Existing Database - Customers - Products - Salespersons - Sales • Millions of Rows RegionCountry Office Customer Salesperson Product Sale Works at Sold by Product sold Sold to Located in Lives in Part of
- 12. Sales Organization DB – What We Want Regions Are Stored in Separate Table Users Can Filter and Sort in Real-Time BufferStore With Millions of Rows
- 13. Sales Organization DB – How To Get There • Launch Ext Speeder • Connect to the ”Salesinfo” database • Create API Endpoint for ”Customer” table • Create Virtual Column ”Region” • Generate Code • Run 1. Connect 2. Generate 3. Deploy
