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 🙏

let mockWithItem = new mockWith.Store(arr);

// 1. 从数据仓库中获取随机 1 个数据
console.log(mockWithItem.getOne());

// 2. 从数据仓库中获取随机 3 个数据列表
console.log(mockWithItem.getSome(3));

// 3. 从数据仓库中获取随机 1 个指定标签为 female 的数据

  • value,必选,桩数据的值,可以是 StringNumberObject 或任意的值。尤其注意的是它也可以为 StoreItem 对象
  • tags,该桩数据的标签,为 Array 类型,要求该数组的元素必须为字符串

4.1.3 addList(list = [])

批量追加多个桩数据到仓库中。

  • list,必选,桩数据列表,为 Array 类型。该数组的元素可以是任意值,参考 addOne 方法中的 value 参数值

4.1.4 getOne(tags, isStrict)

从仓库中获取一个桩数据。

  • tags,要求过滤的标签,为 StringArray 类型
  • isStrict,是否是严格模式,为 Boolean 类型。该值为 true 时,则 tags 中的标签都必须是该桩数据的标签,为 false 时,则只要有一个标签匹配即可

4.1.5 getSome(total = 0, tags, isStrict)

从仓库中获取一个桩数据。

  • total,数量,为 Number 类型
  • tags,要求过滤的标签,为 StringArray 类型
