I have a request-promise function that makes a request to an API. I'm rate-limited by this API and I keep getting the error message:
Exceeded 2 calls per second for api client. Reduce request rates to resume uninterrupted service.
I'm running a couple of Promise.each
loops in parallel which is causing the issue, if I run just one instance of Promise.each
everything runs fine. Within these Promise.each
calls they lead to the same function a with a request-promise call. I want to wrap this function with another queue
function and set the interval to 500
milliseconds so that a request
isn't made after one another, or parallel, but set to that time, on queue. The thing is I still need these promises to get their contents even if it takes a rather long time to get a response.
Is there anything that will do this for me? Something I can wrap a function in and it will respond at a set interval and not in parallel or fire functions one after another?
Update: Perhaps it does need to be promise specific, I tried to use underscore's throttle function
var debug = require("debug")("throttle")
var _ = require("underscore")
var request = require("request-promise")
function requestSite(){
debug("request started")
function throttleRequest(){
return request({
"url": "https://www.google.com"
}).then(function(response){
debug("request finished")
})
}
return _.throttle(throttleRequest, 100)
}
requestSite()
requestSite()
requestSite()
And all I got back was this:
$ DEBUG=* node throttle.js
throttle request started +0ms
throttle request started +2ms
throttle request started +0ms
