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 🙏

z-error

  • verify: 校验字段有效性,合法性。检验不通过返回ZError对象,否则返回null
  • ZError: 错误提示,继承Error。name表示错误名称,code表示错误码,message表示code对应的提示信息,description错误描述。status表示restful api 状态码
  • setLocal:设置多语言错误对照码

如何使用

npm install z-error

const { ZError, getMessage, getErrCodeTable, verify, setLocal } = require('z-error');

// 设置错误码对照表目录
setLocal('zh_cn', `${__dirname}/local`);

let error = new ZError("erro", 1001);

error.getMessage();
error.getMessage('en');
getMessage(1001, 'zh_cn');

let err = verify({account: 'aa'}, ['password']);
err.toJSON();
err.getMessage('zh_cn');

err.lang = 'zh_cn';
err.getMessage();
err.lang = 'en';
err.getMessage();

// 校验account属性值合法性
let err1 = verify({
  account: 'aa'
}, null, {
  account: (val) => {
    if (!val) {
      return false;
    }
    if (val.length < 4) {
      return false;
    }
    return true;
  }
});

// 1,自定义属性缺失及属性合法性错误提示前缀
// 2,校验是否含有password属性,并校验account合法性
err1 = verify({
  account: 'aa'
}, ['password'], {
  account: (val) => {
    if (!val) {
      return false;
    }
    if (val.length < 4) {
      return false;
    }
    return true;
  }
}, "MISSING_PARAMS", "ERR_PARAMS");
