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 🙏

安装

npm install yaka-core --save

npm

import Yaka from 'yaka-core'
const YakaForm = Yaka.YakaForm,
    YakaFormOnFlow = Yaka.YakaFormOnFlow,
    YakaComponent = Yaka.YakaComponent
  1. YakaForm 这个是针对表单开发的yaka
  2. YakaComponent 这个是组件量级的yaka
  3. YakaFormOnFlow 这个是工单系统用的yaka

请按需引用

使用

import React, { Component } from 'react';
import Yaka from 'yaka-core'
// yaka组件需另行安装 
import yakaComponents from 'yaka-components'
const { components, layoutComponents } = yakaComponents
import { config } from './config/'
const YakaComponent = Yaka.YakaComponent

class App extends Component {
  render() {
    return (
      <div className='yaka'>
        <YakaComponent
          config={config}
          components={components}
          layoutComponents={layoutComponents}
        />
      </div>
    )
  }
}
export default App;

  2. init yaka初始化
  3. mounted yaka挂载后
  4. name

layout

layout的配置协议做了改动,更加简洁

  1. name 现在只有在表单组件需要声明键值的时候才要定义
  2. ele 对应原来的component
  3. subs 对应原来的 children
  4. text 标签文本内容
  5. props 组件的属性

废弃项

  1. component
  2. children
  3. state
  4. global
  5. initData
  6. models
  7. functions

以下是新版的配置示例

    "layout": [
        {
            "ele": "Row",
            "subs": [
                {
                    "col": 24,
                    "ele": "h1",
                    "text": "@data",
                    "hide": true,
                    "props": {
                        "style": {
                            "textAlign": "center"
                        }
                    }
                }
            ]
        }
      ]

init

yaka初始化的数据声明、函数初始化、数据监听都集中在这里进行处理

  1. formValue 原initData,用来配置表单的初始值

  2. state 原global,用来配置全局变量

  3. watch 数据监听配置项目

    数据监听配置项目,目前仅支持监听 全局变量,监听后触发的对应动作仅支持调用函数

            "watch": {
                // 声明监听的变量
                "title": {
                    // 声明调用的函数
                    "run": "log"
                }
            }
  4. functions 函数的声明,原models 和functions都转到这里进行配置

    函数声明方式改为配置模板函数的方式,yaka本身有两个函数模板可以使用,用户也可以自己通过外部写入自己的模板然后声明调用。

            "functions": {
                "getItem": {
                    // 函数模板名称
                    "type": "yakaFetch",
                    // 函数模板定义,具体参数应由模板开发者给出配置项
                    "definition": {
                        "headers": {
                            "aa": "@data",
                            "state": "$demo",
                            "string": "string"
                        },
                        "type": "restful",
                        "url": "http://xingyang.com/re/localdns",
                        "params": {
                            "demo": "$title.value",
                            "test": "#name"
                        },
                        "streams": {
                            "$bumen.options": {
                                "path": "data.org",
                                "alias": {
                                    "label": "label",
                                    "value": "value"
                                }
                            },
                            "$test.options": "data.org"
                        }
                    }
                },
                "titleChange": {
                    "type": "stream",
                    "definition": {
                        "$title": "target.value",
                        "#sename": "target.value"
                    }
                },
                "log": {
                    "type": "log",
                    "definition": {
                        "text": "自定义代码模板"
                    }
                }
            },

以下是新版初始化的配置示例

    "init": {
        "formValue": {
            "bumen": "2",
            "name": "1000",
            "checkbox": [
                "Pear"
            ],
            "numbeer": "demo",
            "switch": false
        },
        "state": {
            "demo": "ddddddd"
        },
        "functions": {
            "getItem": {
                "type": "yakaFetch",
                "definition": {
                    "headers": {
                        "aa": "@data",
                        "state": "$demo",
                        "string": "string"
                    },
                    "type": "restful",
                    "url": "http://xingyang.com/re/localdns",
                    "params": {
                        "demo": "$title.value",
                        "test": "#name"
                    },
                    "streams": {
                        "$bumen.options": {
                            "path": "data.org",
                            "alias": {
                                "label": "label",
                                "value": "value"
                            }
                        },
                        "$test.options": "data.org"
                    }
                }
            },
            "titleChange": {
                "type": "stream",
                "definition": {
                    "$title": "target.value",
                    "#sename": "target.value"
                }
            },
            "log": {
                "type": "log",
                "definition": {
                    "text": "自定义代码模板"
                }
            }
        },
        "watch": {
            "title": {
                "run": "log"
            }
        },
        "event": {
            "demo": {
                "onCLick": "#buttonCLick"
            }
        }
    }

mounted

yaka组件挂载后的生命周期钩子,适用于调用一些api函数

配置方式很简单,在run里面用对象键值的形式声明调用的函数名和对应的参数

    "mounted": {
        "run": {
            "demo": {
                "param": 10000
            },
            "getItem": {},
            "log": {
                "param": "dadwa"
            }
        }
    }

mountFunctions 挂载函数接口

外部函数挂载的接口,挂载进去的函数同json配置声明的函数一样的效果。

<YakaFormEngine
    mountFunctions={{
        demo: (data, api) => {
            const { getState, formValueSettingFunction, stateValueSettingFunction } = api
            formValueSettingFunction({ sename: "测试数据" })
            stateValueSettingFunction({
                title: {
                    value: "测试数据"
                }
            })
        },
        yakaChange: (val, api) => {
            console.log(val, '外部接口');
        }
    }}
/>

挂载函数接收两个参数

  1. Data触发元素传入的值

  2. 暴露的yakaApi可以用来修改数据,以下是几个常用的api

    1. formValueSettingFunction 表单数据设置函数
    2. stateValueSettingFunction 全局变量设置函数
    3. formValueGettingFunction 表单数据获取函数
    4. getState 全局变量获取函数
    5. ​getForm 表单示例获取函数

functionTemplates 函数模板接口

单纯使用挂载函数的话,很多场景下都要不断开发函数去应对,这样不利于后期维护和整个生态的发展。沿用了旧版的思路,提出函数模板的概念。

用户可以定义一种可以满足部分场景的函数模板,模板可以根据配置应对不同的细微调整。下面是简单的配置示例

<YakaFormEngine
    functionTemplates={{
        log: (definition, data, api) => {
            const { text } = definition
            const log = () => {
                console.log(e);
            }
            return log
        }
    }}
/>

参数说明

  1. definition 配置字段,可以根据不同函数模板,由用户自己定义
  2. data 触发元素传入的值
  3. 暴露的yakaApi可以用来修改数据,以下是几个常用的api

下面是在json定义和调用的示例

    "init": {
        "functions": {
            "log": {
                "type": "log",
                "definition": {
                    "text": "自定义代码模板"
                }
            }
        },
        "watch": {
            "title": {
                "run": "log"
            }
        }
    }

mountData 挂载数据接口

外部数据挂载的数据现在用 mountData 统一接收

<YakaFormEngine

    mountData={{ data: this.state.test, num: 1 }}

/>

内部接受的用法

    "layout": [
        {
            "ele": "Row",
            "subs": [
                {
                    "col": 24,
                    "ele": "h1",
                    // 使用 @接受mountData
                    "text": "@data",
                    "hide": true,
                    "props": {
                        "style": {
                            "textAlign": "center"
                        }
                    }
                }
            ]
        },
      ]

plugIn 插件接口

新增插件扩展的接口,现在主要是用来扩展layout里面的配置项目

例如我们要在组件配置项目里面加入一个hide的字段,如果这个字段为ture,就不渲染这个组件

插件代码

const logic = (Element, { config, key }, { debug, formCreatFunc, yakaApis }) => {
    if (config.hide) {
 		return null
    }
    return Element
}
export default logic

yaka组件使用方式,插件接口需要传入的是一个数组,用户可以根据需要引入不同的插件扩展

<YakaFormEngine
    plugIn={[logic]}
/>

json配置上的变化

    "layout": [
        {
            "ele": "Row",
            "subs": [
                {
                    "col": 24,
                    "ele": "h1",
                    // 使用 @接受mountData
                    "text": "@data",
                    "hide": true,
                    "props": {
                        "style": {
                            "textAlign": "center"
                        }
                    }
                }
            ]
        },
      ]

插件函数的三个入参

  1. Element, react元素,可以在这边进行包装处理
  2. 组件配置项, config 为对应的json,key为引擎分配给该组件的key值
  3. 可能用到的api,debug 为 debug函数,formCreatFunc 为 表单受控函数,yakaApis为 yakAPI

注意插件函数必须要有return一个元素!!!!

模块化配置体验

yaka配置平台现在按组件细粒度拆分出个个组件的配置,方便用户进行配置微调。

image-20180614204347094

移除 igroot 依赖,改用rc-form

现在yaka仅仅是基于react 和 rc-form 的一个渲染引擎了。

###抽离yaka组件到 yaka-component包

旧版本yaka开发的组件都集成在了yaka-core里面,现在这部分组件抽离出去,成了一个npm包进行引用

yarn add yaka-component
