kontroll/dist/index.mjs

kontroll ("control") is a tiny, dead-simple package for function behavior controls like debounce, countdown, throttle (limit).

const t={};function c(n){const e=typeof n=="function"?n.toString():n;t[e]&&(clearTimeout(t[e].timer),delete t[e])}function a(n){return t[n]}function u(n){return()=>{c(n)}}async function s(n){if(t[n]){t[n].finishing=!0,await t[n].callback();const e=t[n].trailing;c(n),e&&e[0](...e.slice(1))}}function o(n,e,i){if(t[i]?.finishing)return u(i);const r=setTimeout(()=>{s(i)},n);return t[i]={timer:r,callback:e},u(i)}function g(n,e,{key:i=e.toString(),replace:r}={}){return t[i]?(r&&(t[i].callback=e),u(i)):o(n,e,i)}function k(n,e,{key:i=e.toString(),leading:r}={}){if(t[i]&&!t[i].finishing)c(i);else if(r)return f(n,e,{key:i});return o(n,e,i)}function f(n,e,{key:i=e.toString(),trailing:r}={}){if(t[i])return r&&(t[i].trailing=[f,n,e,{key:i}]),u(i);const l=e();return o(n,()=>l,i)}export{c as clear,g as countdown,k as debounce,a as getInstance,f as throttle};
