package com.google.genkit.core.middleware
Middleware support for Genkit Java.
This package provides a middleware pattern implementation for wrapping action execution with pre-processing and post-processing logic. Middleware can be used for:
- Logging and monitoring
- Request/response transformation
- Caching
- Rate limiting
- Retry logic
- Validation
- Error handling
Example usage:
// Create a middleware chain
MiddlewareChain<String, String> chain = new MiddlewareChain<>();
chain.use(CommonMiddleware.logging("myAction"));
chain.use(CommonMiddleware.retry(3, 100));
// Execute with middleware
String result = chain.execute(input, context, (ctx, req) -> {
// Actual action logic
return "Hello, " + req;
});
