Use in Express middleware #35
Description
Hi there,
first off, thank you for this package, it's come in handy several times and always does a great job.
Documentation, however, could be expanded, and I have a question regarding its use in an ExpressJs middleware.
I would like to use "blocked" to investigate the cause of some timeouts we are experiencing in a controller.
I was wondering if I could do something like:
- create a middleware like:
import { Request, Response, NextFunction } from 'express';
import * as blocked from 'blocked-at';
export default (_req: Request, _res: Response, next: NextFunction): void => {
blocked(
(time: any, stack: any) => {
console.log(`Blocked for ${time}ms, operation started here:`, { stack });
},
{ threshold: 1000 },
);
next();
};
- and append this to our route handler
import { Router } from 'express';
import * as RestController from '.';
import ApiKeyAuth from '../../authorization/api-key-auth';
import blocked from '../../middleware/blocked';
router.post('/users', ApiKeyAuth, blocked, RestController.createUser);
I am testing this out with jMeter right now, and I have contrasting feelings on the effectiveness, what are your thoughts on this?
