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 Version Download

File upload component based on ant design vue, which can be used to upload to COS

基于vue3和ant-design-vue的腾讯云对象存储COS上传文件组件。该组件主要服务于文件上传功能,上传文件前发送文件信息给后台,后台计算获得文件上传至COS的地址返回组件,组件再根据远程地址将文件进行推送,可用于业务无关的文件上传服务

安装

npm i vupload-cos -S

Tip: 需要提前安装vue,ant-design-vue和axios

使用

<template>
  <cos-upload 
    :fetch-upload-url="fetchUploadUrl" 
    @success="handleSuccessUpload"
    @fail="handleFailUpload"
  />
</template>
<script setup lang="ts">
import CosUpload from "vupload-cos";

const fetchUploadUrl = async (file: File) => {
    // 根据自身逻辑处理文件,并向后台获取cos上传的url和文件对应的id
    const { url, guid } = await getFileUploadUrl(file);

    return { url, id: guid }    // 最后必须返回url和id
};
const handleSuccessUpload = (guid: string) => {}
const handleFailUpload = (guid: string) => {}
</script>

参数

| 参数 | 类型 | 是否必传 | 默认值 | 备注 | | ---- | ---- | ---- | ---- | ---- | | fetchUploadUrl | (file: File) => Promise<UploadInfo> | true | - | - | 与后台交互获取多文件上传COS的地址和文件id,为自身的业务逻辑 | | acceptSuffix | string[] | false | [".png", ".jpg", "ppt", "mp4", ".jpeg", ".mp3"] | 允许的后缀 | | maxSize | number | false | 524288000 | 文件最大字节数 | | checkFile | (file: File) => boolean | fase | - | 若不传该参数,则仅对文件做大小和后缀校验;返回值true为通过校验,false为不通过校验,不会进行文件上传 | | notification | boolean | false | true | 内置文件校验不通过时是否通过message进行通知 |

其中UploadInfo的类型如下:

interface UploadInfo {
  url: string;
  id: string | number;
}

组件内置的校验包括文件大小和后缀,若要实现更多功能请使用checkFile函数

事件

| 事件名 | 类型 | 备注 | ---- | ---- | ---- | | success | (id: sring) => void | 文件成功上传回调 | | fail | (id: sring) => void | 文件上传失败回调 | | error | (err: Error) => void | 文件上传过程发生的错误回调 |
