一个小型(139B 至 204B)实用程序,用于调整函数的执行速率
A tiny (139B to 204B) utility to regulate the execution rate of your functions
$ npm install --save throttles
There are two "versions" of throttles, each of which different purpose:
Size (gzip): 139 bytes
This is the primary/default mode, meant for managing single queues.
Size (gzip): 204 bytes
This is the opt-in mode, meant for managing a low priority and a high priority queue system.
Items within the "high priority" queue are handled before the low/general queue. The limit is still enforced.
Selecting a Mode
// import via npm module
import throttles from 'throttles';
import throttles from 'throttles/priority';
// import via unpkg
import throttles from 'https://unpkg.com/throttles/index.mjs';
import throttles from 'https://unpkg.com/throttles/priority/index.mjs';
