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 🙏

Readme

FAST Integration Webpack Plugin

包含2个功能

  1. 集成天眼探针
  2. 上传sourcemap

版本日志

1.0.6

  1. 调整hashKey的校验和处理方式(避免错误填写导致API失败)

1.0.5

  1. 修复使用集成功能时环境参数拼接错误

1.0.4

  1. 额外导出一个FastIntegrationWebpackPlugin(需要修改引用方式)
  2. 修复在容器中node方式调用上传sourcemap时,配置了deleteSourcemapAfterUpload时报错的问题

1.0.3

  1. 新增一个函数调用的方式
  2. webpack方式不再支持extra_dir

插件功能

fast-integration-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(webpack的devtool配置),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 | | :--- | :--- | :--- | :--- | :--- | | hashKey | string | 项目唯一标识 | 是 | - | | enableTrackerIntergration | boolean | 是否启用探针集成功能 | 否 | false | | trackerEnv | string | 探针集成环境 | 否 | prod | | htmlEntryPath | string[] | 探针脚本注入的入口html文件路径 | 是 | ['index.html'] | | enableSourcemapUpload | boolean | 是否上传sourcemap | 否 | true | | buildingSourcemapUploadPrefix | string | 上传sourcemap的路径附加前缀 | 否 | - | | deleteSourcemapAfterUpload | boolean | 是否在输出阶段删除.js.map和.css.map文件 | 否 | true |

使用

使用npm安装

npm i fast-integration-webpack-plugin -D

使用yarn安装

yarn add fast-integration-webpack-plugin

以webpack插件形式使用

注意,作为webpack插件使用时,不再支持追加目录,仅上传构建过程中产生的文件,如果需要同时处理多个目录下的上传,请以函数形式调用的方式使用

在webpack中

import path from 'path'; // 需要额外上传某个文件
plugins: [
    new FastIntegrationWebpackPlugin({
      hashKey: '这里使用平台上数据接入步骤中复制出来的即可',
      // 探针集成的相关参数
      enableTrackerIntergration: true,
      htmlEntryPath: ['index.html'],
      // sourcemap上传相关参数
      enableSourcemapUpload: true,
      deleteSourcemapAfterUpload: true
    })
]

在umi中 config.js

import FastIntegrationWebpackPlugin from 'fast-integration-webpack-plugin';
import path from 'path';
export default {
  devtool: 'hidden-source-map', // 开启sourcemap
  chainWebpack: config => { // 使用fast-integration-webpack-plugin插件
    config
    .plugin('fast-integration-webpack-plugin') 
    .use(new FastIntegrationWebpackPlugin({
      hashKey: '这里使用平台上数据接入步骤中复制出来的即可',
      // 探针集成的相关参数
      enableTrackerIntergration: true,
      htmlEntryPath: ['index.html'],
      // sourcemap上传相关参数
      enableSourcemapUpload: true,
      buildingSourcemapUploadPrefix: 'app',
      deleteSourcemapAfterUpload: true
    }))
  },
  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: {
  }
}

以函数形式调用

该模式下独有的配置项 | 配置 | 字段类型 | 说明 | 是否必填 | 默认值 | | :--- | :--- | :--- | :--- | :--- | | uploadDir | (DirType|string)[] | 待上传的目录的绝对路径 | 是 | - |

DirType | 字段 | 字段类型 | 说明 | | :--- | :--- | :--- | | path | string | 目录绝对路径(path.resolve(__dirname, "{路径}")) | | uploadPrefix | string | 上传目标目录的附加前缀 |

const { uploadSourcemapToFast } = require('fast-integration-webpack-plugin');

uploadSourcemapToFast({
  hashKey: 'xxxxx',
  uploadDir: [
    { path: path.resolve(__dirname, './gcxt_dist'), uploadPrefix: 'applications/gxct' },
    path.resolve(__dirname, './dist')
  ],
  deleteSourcemapAfterUpload: true
});

上传时间

上传时间不定,根据当前网络状况决定,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",
  },
