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 🙏

npm
i
circular - dependency - plugin - D   // webpack的循环引用问题检查插件


provide
api
用于父级组件向下游组件统一传递需要用的对象


父组件里
const context = {
    SchemaItem,
};
provide("vjsf", context);

孙子组件里拿到
const context = inject("vjsf");


传递的特性

A组件 里用了B组件 和  C组件
B组件里用了D组件

那么A组件提供的对象  B C D都可以拿到
如果B C D没有自己提供对象 那么B C D 拿到的就是A组件里给的对象
如果B组件里提供了对象 那么B组件就会基于A组件的对象搞一个新的对象然后把属性放进去  B组件提供的对象只有D可以拿到 也就是只有自己的孙子组件可见




    // 在 setup函数中可以使用 watchEffect  函数中用到的响应式对象 就是watchEffect函数依赖的对象  这些对象发生改变就会导致watchEffect重新被执行
watchEffect(() => {
    console.log(context.tag);
});

//setup函数返回的那个 rander函数 也是一样的   里面依赖的响应式对象有改变 就会导致重新执行  进而触发刷新
//provide 也可以结合 响应式对象来用的  provide下去的对象也就是响应式的
利用抛错来限定类型
export function useVJSFContext() {
  const context: { SchemaItem: CommonFieldType } | undefined =
    inject(SchemaFormContextKey);

  if (!context) {
    //通过抛错 可以让ts编译器知道 这个函数必然只有context这一种返回值 所以只要写了这个抛错 ts就会自动认定这个函数的返回值类型是{ SchemaItem: CommonFieldType }
    throw Error("SchemaForm needed");
  }

  return context;
}
