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

TS-Terser Fork自terser,从原来的Javascript实现修改为Typescript实现。

项目背景

Terser/Uglifyjs 是前端领域广泛使用的代码压缩工具,但其在代码量较大时,性能表现不佳。

从理论上来说,Terser/Uglifyjs在做的事情是CPU密集型任务,如果使用性能较好的语言(如C/C++、Rust)重写,应能获得不错的性能提升。

但是重写的风险与工作量较大,难以把控,我更倾向于翻译的方式。因为C/C++、Rust等均为强类型语言,先将Javascript项目转换成Typescript项目,有助于降低翻译的工作量。

同时也会产出一份Typescript的项目。

目前此项目尚处于开发阶段,请勿用于生产环境!

项目目标

  • 将代码(不包含测试用例)全部转为Typescript语言。
  • 消除Any类型, 并启用严格的类型检查。为切换到强类型语言做准备。

当前进展

  • [x] 独立发布版本
  • [x] 更新文档
  • [x] 将源码文件修改为TS文件
  • [x] 重构项目代码结构,从原来的一类方法写在一个文件中,改为一个类的所有方法在一个文件中
  • [x] 将AST相关类定义统一,梳理类定义,删除类工厂
  • [x] 将AST相关的类拆分成小文件,每个文件一个类,并解决循环依赖问题
  • [x] 删除 instanceOf / isAst 操作,改为实例方法实现
  • [x] 添加类型信息
  • [x] 启用noImplicitAny等strict校验
  • [ ] 消除any类型
  • [x] 添加private/public/protected信息
  • [ ] 重构在Rust中无等价对应写法的写法
