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 🙏

fis-preprocessor-defines

说明

fis2预编译阶段插件,用来替换代码中已定义的变量。比如针对生产、开发环境替换process.env.NODE_ENV变量,以编译压缩react、vue等前端framework。

支持常量替换正则替换

test

编写test/src.js, 执行npm test,查看test/build.js

使用


fis.config.merge({
    ...,
    modules: {
        preprocessor: {
            js: 'defines'
        }
    },
    settings: {
        preprocessor: {
            defines: {
                strings: {
                    'process.env.NODE_ENV': process.env.NODE_ENV ? JSON.stringify(process.env.NODE_ENV) : JSON.stringify("development")
                }
            }
        }
    }
});

#配置

  • 常量替换: 用来替换常量。key: value, key为要替换的常量,value为替换后的内容。
  • 正则替换: 通过自定义正则的方式替换。[{pattern: pattern, replacer: replacer}]。 pattern为正则对象,replacer为用来替换的字符串或者函数。参考:str.replace(pattern, replacer)

var config = {
  // 常量替换
  strings: {
    'process.env.NODE_ENV': JSON.stringify('production'),
    'FUN': function() {
      console.log('fun');
    },
    OBJECT: {
      a: 'a',
      b: 'b',
      c: 'c'
    },
    STR: JSON.stringify('i am comming !'),
    NULL: null,
    UNDEFINED: undefined,
    TEST: 'window.test'
  },
  // 正则替换
  regs: [
    {
      pattern: 'hello world !',
      replacer: 'HELLO WORLD !'
    },
    {
      pattern: /hello ([ABCD]) ([ABCD]) ([ABCD]) ([ABCD]) !/ig,
      replacer: function($0, $1, $2, $3, $4) {
        return 'hello ' + $1 + ' `I AM B` ' + $3 + ' ' + $4 + ' !';
      }
    }
  ]
};

注意

  • 如配置TEST, xxxx.TEST不会替换,但是TEST.xxxx会被替换。
  • 如果要将一个本身不在字符串中的字符串,替换为字符串str,值需要为JSON.stringify(str)
