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 🙏

Sifo 拖拽模型插件,在以任意组件与初始 Schema 渲染的基础上,支持对组件进行即时拖拽,构建出新的 Schema.

在线体验:sifo-mplg-drag-react

类实例化参数

| 参数名 | 参数类型 | 描述 | 默认值 | | ---------------- | ---------------------| ---------------- | ------------| | getDraggable | func: node => bool | 节点是否可拖拽 | () => true | | getDroppable | func: node => bool | 节点是否可拖入 | () => true | | dropFilter | func: args => bool | 拖拽过滤方法 | () => true | | deleteChecker | func: (id, nodeInfo) => bool | 节点是否可删除 | () => true | | SifoDragEditor | React.Component | 拖拽工作面板组件,可使用内置的SifoDragEditor,也可以自定义拖拽工作面板,方法请参考内置的组件 | null |

设计器 props:

  • id: 设计器节点id
  • instanceId: sifoApp 实例id
  • onDragStart: 拖入添加时调用,参数是节点数据 (newNode)=> bool;
  • onDragEnd: 拖入动作结束时调用
  • updateAttributes: 更新节点属性,(id, attributes, needReload = false) => {
  • updateId: 更新节点id,(id, newId) => void;
  • replaceComponent: 更新节点组件,(id, componentName, needReload = false) => void;
  • deleteNode: 删除指定节点,id=>void;
  • addChildNode: 添加子节点,(newNode, targetId) => bool;
  • getSchema: 获取编辑后的schema,等效于 () => this.mApi.getEditedSchema(),
  • getNodeInfo: 获取指定节点信息,id => info;
  • getDomById: 获取指定节点的DOM,id => Dom;
  • setSelectedId: 设置选中的节点id;

扩展的 mApi 方法

| 方法名 | 参数/类型 | 返回值类型 | 描述 | | ---------------- | -----------------------| --------------------- | ---------| | reloadPage | (object?: { [externals] [, schema] [, plugins] [, components] }, useEditedSchema = false) | ✘ | 创建新实例,重新加载页面,reloadPage 将重跑所有生命周期。useEditedSchema 表示是否使用编辑后的schema来渲染|

使用示例

import SifoApp from "@schema-plugin-flow/sifo-react";
import DragModelPlugin, { SifoDragEditor } from '@schema-plugin-flow/sifo-mplg-drag-react';
import "@schema-plugin-flow/sifo-mplg-drag-react/index.less";
const components = { Container, Input, Select };
const schema = {
  id: 'root',
  component: 'Container',
  children:[]
};
const plgs = [
  {
    modelPlugin: {
      plugin: DragModelPlugin,
      argsProvider: () => {
        return {
          SifoDragEditor,
        }
      }
    },
    componentPlugin: {
      sifo_mplg_drag_editor_id: {
        onComponentInitial: (params) => {
          const { event, mApi } = params;
          mApi.setAttributes(event.key, {
            componentList,
            title: "测试拖拽"
          });
          mApi.addEventListener(event.key, 'onSave', (ctx, schema) => {
            console.log('this is edited schema:', schema);
          });
        }
      }
    }
  }
];
return (
    <SifoApp
      namespace="drag-demo"
      className="drag-demo"
      components={components}
      plugins={plgs}
      schema={schema}
    />
  );

其中,componentList 是提供给默认的组件属性编辑组件使用的组件列表,其格式如下:

const componentList = [
  {
    type: 'input',
    name: '文本',
    component: 'Input',
    init: function () {
      const uuid = Math.random().toString().substr(3, 3);
      return {
        id: 'text_' + uuid,
        attributes: {
          label: '文本-' + uuid,
          fieldKey: 'text_' + uuid
        }
      }
    },
    propsRender: (id, node, api) => {
      return <PropsEditorComp id={id} node={node} api={api}/>
    }
  }
];
