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 🙏

代码

MutexBase - 互斥锁

const mutex: MutexBase;
// 获取 key 等待锁, (最多尝试获取30次,每次间隔在10~20毫秒),获取不到则抛出异常
const unlock = await mutex.lock({
    key: 'key',
    tryCount: 30,
    sleepRange: [10, 20]
});
await unlock(); // 释放锁

// 获取 key 锁,并且设置锁时间为3秒,获取不到则返回 null
const unlock = await mutex.lock({
    key: 'key',
    timeoutSeconds: 3
});
if (!unlock) await unlock();

ThreadBase - 线程

const thread: ThreadBase;

await thread.sleep(1000); // 休眠1000毫秒

await thread.sleepRange(1000, 2000); // 随机休眠1000~2000毫秒

await thread.stopWatch('统计该函数的耗时', async () => {
    let total = 0;
    for (let i = 0; i < 1000; i++)
        total += i;
    return total;
});

// 每间隔 1000 毫秒尝试执行 1 次函数,最多尝试 5 次,如果期间有一次执行正常则返回,否则抛出异常
// 首次执行也需要等待 1000 毫秒
await thread.try(
    async () => {
        console.log('执行函数');
        return '';
    },
    5,
    1000
);
