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 🙏

易用的表单验证器

Readme

原子表单验证器

易用的表单验证器,大小仅有 4KB。

安装

npm install atomic-validator

使用

验证表单

import validator from "atomic-validator";

const formData = {
  name: "",
  mobile: 123456, // 字段值为非字符串,在匹配规则时(指定了rule字段)会被String()强制转换为字符串
  password: "error",
  city: ["重庆", "南岸"],
};

const formRules = {
  name: [
    { required: true, message: "姓名不能为空" }, // 指定required字段表示值不能为空,故对number和boolean类型无效
  ],
  mobile: [
    { required: true, message: "姓名不能为空" },
    { rule: "mobile", message: "手机号格式错误" }, // rule字段的值为字符串表示预设规则名
  ],
  password: [
    { rule: /abc/, message: "密码错误" }, // rule字段的值为正则表达式,使用该自定义正则表达式匹配
  ],
  city: [
    { validator: validator.customize.arrNotEmpty, message: "请选择城市" }, // 内置验证器。可自定义验证器函数,参数为字段值,返回boolean值
  ],
};

const rst = validator.validate(formData, formRules); // 所有字段验证通过,则返回true,否则返回错误数组

console.log(rst);

// 输出:
[
  { field: "name", message: "姓名不能为空" },
  { field: "mobile", message: "手机号格式错误" },
  { field: "password", message: "密码错误" },
];

验证单个字段

import validator from "atomic-validator";

// validator.single() - 多条验证规则
const value = "7777777";
const rules = [
  { required: true, message: "姓名不能为空" },
  { rule: "mobile", message: "手机号格式错误" },
];

const rst = validator.single(value, rules); // "手机号格式错误"

// validator.match() - 单条验证规则
const value = "abc";
const rst = validator.match(value, /abc/); // true
