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 🙏

debug with or without sourcemap

Readme

howToUse

cutjs

适合没有 Source Map 只有源文件的场景报错

> cutjs path/to/error-file.js  1 18904 50
# path/to/error-file.js 需要 debug 的 js 文件
# 1    出错的行号
# 8904 出错的列号
# 50   出错位置前后展示多少个字符
minified Content:
n("Z/b0");function p(e){const t=Object(f["a"])(),[n,r]=Object(l["useState"])(e),o=Object(l["useCallback"])(e=>{t.current
                                                ^^^

view unminified Code:
/user/example/umi.unminify.js:989

执行后生成 unsource.js 格式化后的代码,和错误对应的文件位置信息,方便 debug。

wherejs

适合有 sourcemap 的场景

> wherejs path/to/file.js.map  1 276297
# path/to/file.js.map  压缩代码对应的 source map 文件
# 1                    压缩出错行号
# 276297               压缩出错列号
