Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

任务队列实例

export interface ITask {
    // 任务函数
    fn: (...args: any[]) => any
    // 任务函数所需参数
    params: Array<any>
    // 重试次数,默认为0
    retry: number
    // 任务唯一id
    id: number
}

ITaskQueueHooks

任务队列执行钩子对象

export interface ITaskQueueHooks {
    // 所有任务执行完毕时钩子
    onFinished?: () => void
    // 任务执行成功时钩子
    onTaskSucceeded?: (index: number, task: ITask) => void
    // 任务执行失败时钩子
    onTaskFailed?: (index: number, task: ITask) => void
}

| 返回值 | 返回类型 | 说明 | |-----|------------------|--------| | res | Awaited<any>[] | 执行结果列表 |

runTaskQueue

执行一个异步任务队列,它具有重试机制,当任务执行失败(报错),回重新添加到 队列末尾等待重新执行,一直到执行成功或达到该任务的最大执行次数。

| 参数 | 参数类型 | 默认值 | 说明 | |-----------|-------------------|--------|--------| | taskQueue | Array<ITask> | - | 任务队列 | | hook | ITaskQueueHooks | - | 任务队列执行钩子对象 | | maxRetry | Number | 5 | 最大重试数量 | | log | Boolean | true | 是否打印日志 |

| 返回值 | 返回类型 | 说明 | |-----|---------------------------------|----------------------------| | res | {success:number[], fail: number[]} | 执行结果列表,分别对应执行成功的任务或失败任务的id |
