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 🙏

Readme

qval — 对象校验(可视化规则 / 可选不中断 / 结果对象输出)

qvalmsg.<data>(默认 msg.payload)中的对象执行规则校验,支持可视化配置与批量编辑;内置 Email/URL/IPv4/IPv6/UUID/日期/主机名等格式校验,长度/数值/元素个数边界、集合包含/排除、字段相等等。


主要能力

  • 规则来源:节点内规则 + (可选)msg/flow/global 的传入规则
  • 来源策略:替换 replace / 追加 merge
  • 额外属性:允许 / 禁止额外字段(additionalProperties
  • 失败行为:可选 抛错中断不中断
  • 输出:仅写入结果对象到可配置路径(默认 msg.validation
    { "ok": true|false, "errors": [ "..." ], "details": [ /* Ajv 错误 */ ] }

> 不再写入 `msg.qvalValid` / `msg.qvalErrors`,也不再提供“错误数组独立路径”。

## 运行时状态

* 通过:绿色 · 已通过
* 未通过:黄色 · 未通过(N)
* 异常:红色 · 异常(配置/数据结构错误)

---

## 批量编辑(JSON)

```json
[
  {"property":"email","validator":"required"},
  {"property":"email","validator":"email","error":"邮箱格式不正确"},
  {"property":"age","validator":"minimum_number","value":18}
]
```

---

## 小贴士

* 对象来源路径可写深层:如 `payload.user`
* 结果对象路径支持 `msg` / `flow` / `global`,也支持深层:如 `result.validation`
* 路径中若写入 `msg.xxx` 会在保存时自动规范化为 `xxx`
