rate-limit-ext

Extended rate limit for axios: set how many requests per interval should perform immediately, other will be delayed automatically. Socket errors on long queues are fixed according to other axios-rate packages.

Installing

npm i rate-limit-ext

Usage

import axios from "axios";
import {RateLimitExt} from "rate-limit-ext";
 
//const axiosRate1 = new RateLimitExt(axiosInstance,options);
//available options : {
//  period: default 1000 // calculation period in millisecond
//  reqLimit: default 18 //  max request number for per period
//  reqPerSecond: default 18 // max request number for per second
//  countBeforeReq: default false // if it is true , rate calculations will done before sending request , otherwise calculation will done after any response or error received from axios
//}
 
// sets max 2 requests per 777 milliseconds, other will be delayed
// note reqPerSecond is a shorthand for period: 1000, and it takes precedence ,if specified both with reqPerSecond and period
 
const axiosRate1 = new RateLimitExt(axios.create(), {
  period: 777,
  reqLimit: 2,
});
 
// dont wait response of sended requests to trigger next requests on queue ,
const axiosRate2 = new RateLimitExt(axios.create(), {
  period: 777,
  reqLimit: 2,
  countBeforeReq: true,
});
 
//send max 5 request per  second , waits
const axiosRate3 = new RateLimitExt(axios.create(), { reqPerSecond: 5 });
 
axiosRate1.get("https://argatechnology.com/"); // will perform immediately
axiosRate1.get("https://argatechnology.com/"); // will perform immediately
axiosRate1.get("https://argatechnology.com/"); // will perform after 777 milliseconds from one of first 2 requests RESPONSE
 
axiosRate2.get("https://argatechnology.com/"); // will perform immediately
axiosRate2.get("https://argatechnology.com/"); // will perform immediately
axiosRate2.get("https://argatechnology.com/"); // will perform after 777 milliseconds from first one
 
//------------
 
axiosRate3.get("https://argatechnology.com/"); // will perform immediately
axiosRate3.get("https://argatechnology.com/"); // will perform immediately
axiosRate3.get("https://argatechnology.com/"); // will perform immediately
axiosRate3.get("https://argatechnology.com/"); // will perform immediately
axiosRate3.get("https://argatechnology.com/"); // will perform immediately
axiosRate3.get("https://argatechnology.com/"); // will perform after 1000 milliseconds from one of first 5 requests RESPONSE
 
// options hot-reloading also available
axiosRate3.setPeriod(999); // sets period to 999 milliseconds
axiosRate3.getPeriod(); // 999
 
axiosRate3.setReqLimit(2); // sets request limit to 2
axiosRate3.getReqLimit(); // 2
 
axiosRate3.setRPS(3); // sets period to 1000 millisecond and request limit to 3
axiosRate3.getPeriod(); // 1000
axiosRate3.getReqLimit(); // 2
