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 🙏

错误信息提示框

接入

import { HelpError } from '@qse/help-dialog'

// 设置用户信息
HelpError.defaults.personid = ''
HelpError.defaults.fgsid = ''
HelpError.defaults.studentid = ''
HelpError.defaults.campusid = ''

async function query() {
  const res = await fetch('/api/xx/xx')

  // 当 code !== '0' 时,创建 HelpError
  if (res.err_code !== '0') throw new HelpError(res)

  return res
}

全局捕获 HelpError

import { showHelpDialog } from '@qse/help-dialog'

function handleError(error: Error) {
  showHelpDialog(error)
}

导出对象说明

HelpError

函数签名

export declare class HelpError extends Error {
  info: HelpErrorInfo
  static defaults: HelpErrorInfo
  static isHelpError(error: Error): error is HelpError
  get isValid(): boolean
  constructor(info: HelpErrorInfo)
}

标准错误类,继承与 Error,可以当 Error 使用

通过 HelpError.defaults[xxx] 设置默认参数

通过 HelpError.isHelpError(error) 可以判断 error 是否是 HelpError

通过 error.isValid 判断 HelpError 是否具有合法参数(用于获取帮助信息)

showHelpDialog

函数签名

function showHelpDialog(error: Error): Promise<void>

传递 error 即可,内部会判断是否是合格的 HelpError,不合格显示 Dialog.alert({ content:error.message }),合格显示带有帮助的 dialog
