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

webpack-replace-loader

一个 webpack 打包时用来替换字符串的 webpack-loader 。

中文文档   English document

使用场景举例

1 . 在使用 webpack 项目打包的时候,用来将开发环境的请求 URL 替换为 生产环境的 URL 。

2 . 项目统一查找调整页面配色样式 color , 将 #00ff00 替换为 #ff0700

3 . 大型项目中,依照打包策略在相关文件中写入不同内容。

与 webpack 版本关系

webpack v5,请安装Tag: v5.0.0+ webpack v4,请安装Tag: v4.0.0+ (正在编写中) webpack v3,请安装Tag: v1.0.0+

安装

webpack-replace-loader 作为依赖安装到项目:

 npm install webpack-replace-loader --save-dev

配置使用

配置webpack打包策略:

module: {
  loaders: [
    ...
    {
      test: /test\.js$/,
      loader: 'webpack-replace-loader',
      options: {
        arr: [
          {search: '$BaseUrl', replace: 'https://test.baiduu.com', attr: 'g'},
          {search: '$Title', replace: '百度一下,你就知道', attr: 'g'}
        ]
      }
    }
    ...
  ]
}

示例

test.js :

 var title = '$Title';
 function showTitle () {
   document.title = title;
 }

通过以上 webpack 配置打包后生成 test.js :

var title = '百度一下,你就知道核心价值观';
function showTitle() {
  document.title = title;
}

在上例中,$Title 的作用仅仅是提供一个查找字符串的 锚点 ,并没有实际意义。

Webpack 的其他配置方法

1 . 将 a.js 中的 BaseUrl 只替换第一个为 https://www.baidu.com/api/ ; Title 全部替换为 " 百度开放接口 " 。

2 . 将 b.js 中的 Location 全部替换为 " BeiJing " 。

module: {
  loaders: [
    ...
    {
      test: /a\.js$/,
      loader: 'webpack-replace-loader',
      options: {
        arr: [
          {search: 'BaseUrl', replace: 'https://www.baidu.com/api/'},
          {search: 'Title', replace: '百度开放接口', attr: 'g'}
        ]
      }
    },
    {
      test: /b\.js$/,
      loader: 'webpack-replace-loader',
      options: {
        search: 'Location',
        replace: 'https://www.baidu.com/api/',
        attr: 'g'
      }
    }
    ...
  ]
}

只要你的替换锚点不相同,你也可以合并写:

module: {
  loaders: [
    ...
    {
      test: /(a\.js|b.js|c\.js)$/,
      loader: 'webpack-replace-loader',
      options: {
        arr: [
          {search: 'BaseUrl', replace: 'https://www.baidu.com/api/'},
          {search: 'Title', replace: '百度开放接口', attr: 'g'}
          {search: 'Location', replace: 'BeiJing', attr: 'g'}
        ]
      }
    }
    ...
  ]
}

包括 .css 文件,.less 文件等 : 将color: red; 修改为 color: #0cff00;

.test {
  color: red;
}

配置:

options: {
  search: 'color: red;',
  replace: 'color: #0cff00;',
  attr: 'g'
}

替换后:

.test {
  color: #0cff00;
}

将 a.hml 文件 的 div 标签换为 span 标签。将 class text 换为 box :

<span>$DOM</span>

配置如下:

options: {
  arr: [
    {search: 'span', replace: 'div', attr: 'g'},
    {search: '$DOM', replace: `
      <span class="box">
        <span class="text">百度一下,你就知道</span>
      </span>
    `}
  ]
}

替换后:

<div>
  <span class="box">
    <span class="text">百度一下,你就知道</span>
  </span>
</div>

测试

在 test 目录下进行执行:

 npm install
 npm run test

用浏览器打开:test/dist/index.html。

说明

1.2版本后,已做全字符转义,包含但不限于下列情况均可替换。

search: '<a class__';
search: '.a /bcc .g';
search: '[.a]';
search: '--{a-x}';
search: '({[list]})';
search: '/$/abb^';
search: '<c><d></>';
search: '?+^$@><-';
