The document describes how Ext Speeder can auto-generate a complete backend in minutes by graphically connecting to a database, selecting tables and columns, and pressing "Generate". This generates code that provides a REST API and handles tasks like filtering, sorting, skipping, and caching data for high performance. Ext Speeder aims to reduce traditional backend development time from around 24 hours to under 1 hour.

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”
