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 🙏

mill-upload-fornode

nodejs文件上传模块

安装

npm install mill-upload-fornode --save

表单设置

<form action="/uploada" enctype="multipart/form-data" method="post">

提供两种使用方式

  1. 简单使用
    • 参数
      • request对象
      • 指定路径,默认路径为当前文件夹./
      • 文件前缀
    • 将文件上传到指定路径,按照上传前的本地名字
    • 返回所有的表单字段,其中包含文件字段,字段值为文件保存的路径
let upload = require('mill-upload-fornode');
...
upload.parseForm(req,"./img",(new Date()).getTime())
	.then(function (fields) {
      res.writeHead(200, {'content-type': 'text/plain'});
      res.write('received upload:\n\n');
      res.end(util.inspect(fields));
	});
  1. 自定义逻辑
upload.parseFormBase(req,"./img")
	.then(function (fields) {
      res.writeHead(200, {'content-type': 'text/plain'});
      res.end(JSON.stringify(fields,null,4));
	});
  • 将文件以哈希码的方式保存
  • 返回如下详细信息
  • 用户可以自行进行fs.rename()
{
    "fields": {
        "title": [
            ""
        ]
    },
    "files": {
        "haha": [
            {
                "fieldName": "haha",
                "originalFilename": "屏幕快照 2017-07-09 上午2.21.42.png",
                "path": "img/u1LVA-zHXuQ0NZWzjdZxIP3w.png",
                "headers": {
                    "content-disposition": "form-data; name=\"haha\"; filename=\"屏幕快照 2017-07-09 上午2.21.42.png\"",
                    "content-type": "image/png"
                },
                "size": 90498
            }
        ]
    }
}
  1. 其他方式
  • init方法将在全局对象上绑定一个parseForm方法,使用和parseFormBase一样
require('mill-upload-fornode').init('./img')
