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 🙏

@meshflow/form

v0.1.8

Published

Form orchestration adapter for @meshflow/core, providing high-level form logic and schema validation.

Readme

@meshflow/form

基于 @meshflow/core 的高性能、强类型、无头(Headless)表单逻辑驱动器。

NPM Version Peer Dependency

🌟 核心优势

@meshflow/form 是专为复杂中后台设计的表单逻辑层。它不提供任何 UI 组件,而是通过拓扑任务编排,赋予表单处理 500+ 节点复杂联动的能力。

  • 🏗️ 真正的无头架构:通过 UITrigger 与 UI 框架(Vue/React/Solid)解耦,逻辑运行在纯 JS 引擎中。
  • ⚡ 极致类型推导:基于 TypeScript 的路径感知,实现超大规模 Schema 的自动路径补全。
  • 🧩 插件化扩展:支持通过 modules 注入功能模块(如 Undo/Redo 历史记录)。
  • 🌊 异步时序安全:内置水位线机制,原生解决高频操作下的异步回填竞态问题。

🚀 快速上手

安装

npm install @meshflow/form
初始化引擎
import { useMeshForm } from "@meshflow/form";

const schema = {
    type: 'group',
    name: 'billing',
    label: '计费与汇总',
    children: [
        { type: 'number', name: 'totalPrice', label: '预估月度总价', value: 0, },
        { type: 'input', name: 'priceDetail', label: '计费项说明', value: '基础配置费用'}
    ]
};
const engine = useMeshForm('engine', schema, {
  UITrigger: {
    // Vue 响应式绑定
    signalCreateor: () => ref(0),
    signalTrigger(signal) { 
      signal.value++; 
    }
  }
});
添加联动依赖
engine.config.SetRule("billing.totalPrice", "billing.priceDetail", "value", {
  logic: ({ slot }) => {
    const [total] = slot.triggerTargets; // 从触发目标中解构出 totalPrice
    return total > 2000 ? "大客户折扣" : undefined;
  }
});
