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 🙏

FAST SourceMap Upload

上传SourceMap文件node脚本

插件功能

fast-sourcemap-upload根据用户配置的文件目录,自动递归搜索配置目录下的source文件和.map文件,并根据文件名与oss仓库文件做比对,实现增量上传源文件与map文件

提示:避免在开发环境使用该插件,在生产环境再启用该插件

配置项

配置 | 字段类型 | 说明 | 是否必填 | 默认值 ---|---|---|---|--- app_key | string | 项目唯一标识 | 是 | 无默认值 product_code | string | product_code | 是 | 无默认值 app_code | string | app_code | 是 | 无默认值 upload_url | string | 待上传文件目录路径(绝对路径) | 是 | 无默认值 is_delete_source_map | boolean | 是否在上传完map文件后删除输出目录的.js.map和.css.map文件,默认值为true | 否 | true timeout | number | 单个文件上传超时时间,默认值300000,5分钟 | 否 | 300000 sts_url | string | STS上传权限获取接口 | 否 | 无默认值 force_update | boolean | 是否强制上传 | 否 | false

使用

npm i fast-sourcemap-upload -D

创建一个js文件 nodeUpload.js


const nodePlugin = require('fast-sourcemap-upload');
const path = require('path')
nodePlugin({
  app_key: 'your app——key',
  product_code: 'your product_code',
  app_code: 'your app_code',
  upload_url: path.resolve(__dirname, 'your dir_path'),
  is_delete_source_map: true,
})

终端

node nodeUpload

上传时间

上传时间不定,根据当前网络状况决定,oss仓库存在的文件不会上传(根据文件路径与名称区分,请开启文件名hash)。

注意事项

  1. 前端构建工具请开启文件名hash模式,增量上传是根据文件路径与文件名进行区分的。

  2. 如果您的项目将css、less、scss文件打包入您的js文件时,请在相关loader中关闭您css、less、scss相关文件的sourcemap生成配置。以防止生成的map文件一并打包入您的js文件中,导致js文件大小超过预期。

例:

{
  loader: 'style-loader',
  options: {
    sourceMap: false
  }
}
  1. 由于node对进程的内存分配有默认设置,32位系统 node默认分配内存 0.7g左右,64位系统默认分配内存1.4g左右, 如果项目复杂,在开启souremap生成选项时,打包的时候,可能出现内存不足导致打包失败的情况

例:

解决方案:

配置打包命令时,修改node进程占用内存的大小 --max-old-space-size

例:

package.json

"scripts": {
    "build": " node --max-old-space-size=4096 ./scripts/build.js",
  },
