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 🙏

fileList 的最小格式 (格式稍显麻烦,是为了 onChange 的返回值可以传回给 fileList)

[
    {
        name: '', // 文件名称,列表形式必填
        ext: '', // 文件扩展名。例如 jpg。可选,不填时无法根据类型展示对应图标
        fileType: '', // 文件 mimetypes 类型。 例如 image/jpg。 可选,不填时无法根据类型展示对应图标
        response: {
            url: xxx,  // 文件链接,必填
            canRemove: true, // 是否可以删除,可选
            downloadUrl: 'xxxx', // 下载 URL,可选
        }
    }
]

fileList 更新说明

Since 3.3.10 版本,当前已存在的文件列表数据不需要自己再组装一个 response 结构,组件内部会根据顶层数据来组装:

[
  {
    name: 'My File',
    ext: '.jpg',
    fileType: 'image/jpg',
    url: 'https://www.foo.bar/aaa.jpg',
    previewUrl: '', // 可选
    canRemove: true // 可选
  }
]

Events

| name | arguments | description | |----------|--------------|------------------| | onChange | fileList | 在上传成功或文件移除后触发,返回文件队列,包括自己传入的fileList | | onCancel | file | 文件移除后触发,上传的文件和默认列表的文件格式会有所不同,文件格式参见下面的 fileList 格式| | onfileuploaderror | File, Error | 文件上传失败 |

onChange 的 fileList 的枚举格式有如下几种

[
    // 上传后的文件的格式, response 即服务器返回的值
    {
        id: 'xxxx', // 如果 response.content 中有提供
        url: 'xxx', // 如果 response.content 中有提供
        previewUrl: 'xxx', // 如果 response.content 中有提供
        type: 'upload',
        ext: file.ext,
        name: file.name,
        response: JSON.parse(file.response)
    },
    // 预览用文件的格式, `props.fileList` 相关, responce 即 `props.fileList` 里传入的格式。
    {
        type: 'list',
        response: file
    },
    // 被删除的文件的格式
    {
        type: 'delete',
        subType: 'list/upload', // 与上面两种类型对应,用于解析 response
        response: file // 与上面的 subType 相对应
    }
]
