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 🙏

swc-plugin-stage-output

v0.1.1

Published

SWC plugin: write AST-as-code to .swc-plugin-stage-output (same dir structure, .txt suffix, random filename)

Readme

@canyonjs/swc-plugin-stage-output

只做一件事的 SWC 插件:拿到 AST 后还原成源码,写入阶段产物目录

功能

  • 对每个经手的文件:用 to_code(program) 把当前 AST 转成源码字符串。
  • 写入目录:.swc-plugin-stage-output(与宿主约定用虚拟机映射路径 /cwd/)。
  • 目录结构:与源文件一致(如 src/foo/bar.js.swc-plugin-stage-output/src/foo/)。
  • 文件名{原文件名无扩展名}-{随机数}.txt,避免重复覆盖。
  • 跳过 node_modules,不为其生成产物。

构建与测试

# 构建 wasm
npm run prepack

# 跑测试:先 prepack,再用 swc 编译 features → dist,并写入 .swc-plugin-stage-output
npm run test-swc-plugin

测试输入在 features/(如 add.jsjian.js),输出:dist/(编译结果)、.swc-plugin-stage-output/features/*.txt(阶段产物)。
