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 🙏

Upload 上传组件

适用于 @midwayjs/faas@midwayjs/web@midwayjs/koa@midwayjs/express 多种框架的通用上传组件,支持 file (服务器临时文件)、stream (流)多种模式。

Usage

  1. 安装依赖
tnpm i @midwayjs/upload --save
  1. 在 configuration 中引入组件,
import * as upload from '@midwayjs/upload';
@Configuration({
  imports: [
    // ...other components
    upload
  ],
})
export class AutoConfiguration {}
  1. 在代码中获取上传的文件
@Controller('/')
export class HomeController {

  @Inject()
  ctx;

  @Post('/upload')
  async upload(@Files() files: upload.UploadFileInfo[], @Fields() fields) {
    /*
    files = [
      {
        filename: 'test.pdf',        // 文件原名
        data: '/var/tmp/xxx.pdf',    // mode 为 file 时为服务器临时文件地址
        fieldName: 'test1',          // 表单 field 名
        mimeType: 'application/pdf', // mime
      },
      {
        filename: 'test.pdf',        // 文件原名
        data: ReadStream,    // mode 为 stream 时为服务器临时文件地址
        fieldName: 'test2',          // 表单 field 名
        mimeType: 'application/pdf', // mime
      },
      // ...file 下支持同时上传多个文件
    ]

    */
    return {
      files,
      fields
    }
  }
}

配置

export const upload = {
  // mode: UploadMode, 默认为file,即上传到服务器临时目录,可以配置为 stream
  mode: 'file',
  // fileSize: string, 最大上传文件大小,默认为 10mb
  fileSize: '10mb',
  // whitelist: string[],文件扩展名白名单,默认为 null
  whitelist: null,
  // tmpdir: string,上传的文件临时存储路径
  tmpdir: join(tmpdir(), 'midway-upload-files'),
  // cleanTimeout: number,上传的文件在临时目录中多久之后自动删除,默认为 5 分钟
  cleanTimeout: 5 * 60 * 1000,
  // base64: boolean,设置原始body是否是base64格式,默认为false,一般用于腾讯云的兼容
  base64: false,
}
