timed-silky/dist/task.js

Timed-Silky 是基于一款基于 TypeScript 的定时任务调度器。得益于 TypeScript，Timed-Silky 可以用符合特定句式的自然语言描述任务的调度规则，提供丝滑的链式调用接口。

function createTask(callback, ruleChain, ...args) {
    let lastRunAt = 0;
    let timeOutHandle;
    let f = async function () {
        let r = callback(...args);
        if (r instanceof Promise) {
            await r;
        }
        clearTimeout(timeOutHandle);
        lastRunAt = Date.now();
        let nextRunAt = ruleChain.generateNextTime(lastRunAt);
        setTimeout(f, nextRunAt - Date.now());
    };
    let nextRunAt = ruleChain.generateNextTime(lastRunAt);
    timeOutHandle = setTimeout(f, nextRunAt - Date.now());
}
export { createTask };
