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 🙏

cy-serialize-error

🔒 超安全 Error 序列化工具,适合日志记录、调试和上报

cy-serialize-error 可以将 Error、普通对象、Map、Set、Array、TypedArray、ArrayBuffer、Date、RegExp 等 JavaScript 数据结构安全地序列化成可读的 JSON 对象,支持:

  • 循环引用检测
  • 最大递归深度限制
  • Map / Set 序列化
  • 基本类型原样返回
  • 自定义序列化器

安装

npm install cy-serialize-error -D

使用

import { safeSerializeError } from 'cy-serialize-error';

// 基本 Error
const err = new Error('测试错误');
console.log(safeSerializeError(err));
/*
{
  name: 'Error',
  message: '测试错误',
  stack: 'Error: 测试错误\n    at ...'
}
*/

// 支持 cause
const cause = new Error('原因');
const mainError = new Error('主错误');
(mainError as any).cause = cause;
console.log(safeSerializeError(mainError));
/*
{
  name: 'Error',
  message: '主错误',
  cause: { name: 'Error', message: '原因', stack: '...' },
  stack: '...'
}
*/

// 循环引用
const obj: any = {};
obj.self = obj;
console.log(safeSerializeError(obj));
/*
{ self: '[Circular]' }
*/

// 序列化 Map 和 Set
const map = new Map([
  ['a', 1],
  ['b', { nested: 2 }]
]);
const set = new Set([1, { x: 2 }]);
console.log(safeSerializeError(map));
console.log(safeSerializeError(set));
