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 Webpack Plugin

上传SourceMap文件webpack插件

插件功能

fast-sourcemap-upload-webpack-plugin是基于webpack4开发的webpack插件,为天眼探针定位上报异常在源代码中的确切位置提供source文件和map文件

在webpack中作为插件使用,需要开启项目的sourceMap文件生成选项,插件会根据输出目录递归搜索 .js文件和.js.map文件 .css.map文件

其中,.js文件和.js.map文件会上传到天眼 .css.map文件不会上传,根据插件配置项 可以决定插件是否删除输出目录中的 .js.map文件和.css.map文件

提示:避免在开发环境使用该插件,否则由于上传文件可能导致热加载时间过长,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 is_delete_source_map | boolean | 是否在输出阶段删除.js.map和.css.map文件 | 否 |true extra_upload_dir | array | 需要额外上传的文件夹列表,例如,你的项目中,某个文件夹下的资源是单独饮用,未在webpack生命周期中时,可以使用 配置好路径 /a/b/c, 上传时将会把/a/b/c下的js、js.map文件上传到天眼 | 否 |[] timeout | number | 单个文件上传超时时间,默认值300000,5分钟 | 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-webpack-plugin -D

在webpack中

import path from 'path'; // 需要额外上传某个文件
plugins: [
    new FastSourcemapUploadWebpackPlugin({
      app_key: your app_key,
      product_code: your product_code,
      app_code: your app_code,
      is_delete_source_map: true,
      // force_update: false,
      // extra_upload_dir: ['需要额外上传的文件夹绝对路径(path.resolve(__dirname, `路径`))'], 该配置只针对需要的人员
    })
]

在umi中 config.js

import FastSourcemapUploadWebpackPlugin from 'fast-sourcemap-upload-webpack-plugin';
import path from 'path';
export default {
  devtool: 'hidden-source-map', // 开启sourcemap
  chainWebpack: config => { // 使用fast-sourcemap-upload-webpack-plugin插件
    config
    .plugin('fast-sourcemap-upload-webpack-plugin') 
    .use(new FastSourcemapUploadWebpackPlugin({
      app_key: your app_key,
      product_code: your product_code,
      app_code: your app_code,
      is_delete_source_map: true,
      //extra_upload_dir: ['需要额外上传的文件夹绝对路径(path.resolve(__dirname, `路径`))'],该配置只针对需要的人员
    }))
  },
  plugins: [
    // ref: https://umijs.org/plugin/umi-plugin-react.html
    ['umi-plugin-react', {
      ...
    }]
  ],
  hash: true,
  targets: {
    ie: 9
  },
  // 路由配置
  routes: pageRoutes,
  // ANTD主题配色
  theme: {
  },
  // Webpack Configuration
  proxy: {
  }
}

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. 配置devtool生成sourcemap文件时,如果您的项目需要保留sourcemap文件,那么推荐使用 'source-map' 模式,该模式为 bundle 添加了一个引用注释,以便开发工具知道在哪里可以找到它。 如果您的项目不需要保留生产的sourcemap文件,推荐使用 'hidden-source-map' 模式,与source-map 相同,但不会为 bundle 添加引用注释。

  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

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",
  },
