Middleware
Middleware interface for TypeScript and Python
Middleware Interface
Middleware has one method, use(). Call next() to run the rest of the pipeline and get its result.
interface MiddlewareInterface {
use(
context: ExecutionContext,
next: () => Promise<any>
): Promise<any>;
}async def use(self, context: ExecutionContext, next_fn)from nitrostack import use_middleware
@use_middleware(AuditMiddleware)
async def handler(...):
...Call await next_fn() to continue the pipeline.
Example
A middleware that runs code before and after the handler:
@Middleware()
export class MyMiddleware implements MiddlewareInterface {
async use(context: ExecutionContext, next: () => Promise<any>): Promise<any> {
// Before
const result = await next();
// After
return result;
}
}
