API Gateway Recipes: Solutions for Operation, Integration & Security
summary
Collection of concrete gateway patterns and what actually works: use short-circuit + template mock to block, deprecate or fake endpoints and return harmonized error bodies; use an expression-language for routing, rate limits and conditional error handling (JSONPath, XPath, Go/Velocity templates or Lua/JS scripts); build a lightweight token service by signing JWTs in ~20–30 lines of code; translate SOAP to REST by pasting SOAP-UI templates and filling with JSONPath/XPath; stacking 500 gateways measures ~200 ms round trip.
