deduplicate multiple http request to a single endpoint
npm install http-deduplicate
Deduplicate multiple http request to a single endpoint.
You have an application composed of multiple HTTP servers, and you need
to issue HTTP requests from your frontend to other internal endpoints.
So, you call your endpoint for all requests. This module allows you to
reduce the traffic and response time by calling a given URL only once at
any given interval.
In my tests, http-deduplicate increases the throughput by a 2-5x factor, depending on
the application.
``
npm install http-deduplicate -g
`js`
deduplicate(url, function (err, data, cb) {
// do something async
cb()
// cb is optional and can be omitted
})
See example.js for a full example
Calls address (as defined inhttp and
https only once in a given period, all the other requests will receive the same data.
For extreme optimizations in high load scenarios, you can serve the
latest returned value up until all callback` (if present) are
called.
