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 🙏

CandyConditionBuilder

适用于Angular项目,逻辑构建器。

使用样例

安装方式

npm i candy-condition-builder

在对应module.ts中:

import {CandyConditionBuilderModule} from "candy-condition-builder";

@NgModule({
  imports: [
    ...
    CandyConditionBuilderModule
  ]
})

在html中:

<candy-condition-builder #conditionBuilder
 [conditionCategories]="categories"
 [conditionSettings]="conditions" 
 [nodes]="buildedNodes"
 [mode]="'JAVASCRIPT'"
></candy-condition-builder>

example1

用户可以自己组合并设置所需要的业务逻辑,上图就可以解读为:

航班日期为 2020-10-28 ~ 2020-10-29 之间 北京首都机场起飞的VIP航班

操作的时候需要注意:条件可以拖拽到逻辑分组之中,逻辑分组可以包含其他逻辑分组,但根节点只能是一个逻辑分组或者单一逻辑条件。

用户可以用此控件构建复杂的逻辑条件。

同时,用户可以选择讲mode设置为 SQL, 用于范围SQL语句中 WHERE 之后的逻辑表达式

配置项

| 参数 | 说明 | 类型 | 默认值 | 例子 | | ---- | ---- | ---- | ---- | --- | | [conditionSettings] | 配置逻辑条件的数据 | FieldCondition[] | [] | 详情请见注意项1 | | [conditionCategories] | 配置逻辑条件对应的分组 | CategorySetting[] | null | 详情请见注意项2 | | [nodes] | 用于显示已保存了的条件数据 | any[], 数据格式详见@circlon/angular-tree-component 10.x 中树结构 | [] | 详情请见注意项3 | | [isConditionRequired] | 条件验证时是否需要判断有没有选取条件 | boolean | true | | | [mode] | 返回逻辑表达式的模式 | 'JAVASCRIPT', 'SQL' | 'JAVASCRIPT' | |

注意事项

  1. [conditionSettings] 类型为FieldCondition[]:

    export interface FieldCondition {
      type: string; // 设置为'field' 即可
      category?: string; // 用于分类型显示条件
      field: string; // 
      fieldName: string; // 显示的标签
      fieldType: string; // 条件类型
      conditions: any[]; // 用于选择的条件,例如 等于、不等于、包含、不包含
      selectOptions?: any; // 如果 fieldType 为 select 的时候需要提供配置
    }

    | 字段 | 说明 | 设置值 | | --- | --- | --- | | type | 设置为'field' 即可 | | | category | 对应 CategorySetting 中 key 所对应的字符,用于下拉框中分组显示选项内容|| | field | 条件对应的实体以及对象的属性,例如 flight.flightDate,flight.taskType 之类的,需要是 实体.属性 的形式|| | fieldName | 用于下拉框显示的文本 || | fieldType | 条件类型 | string, number, date, datetime, time, nullCheck, select, multiSelect, fieldCompare | | conditions | 用于选择的条件,例如 等于、不等于、包含、不包含, 格式需要为 {value: xxx, label: xxx} | 详细部分详见下表| | selectOptions | 当fieldType为select的时候需要设置 | [{value: xxx, label: xxxx}, {value: xxx, label: xxxx}, ...]|

    Conditions可配置属性

    | 类型 | 可设置的类型 | | --- | --- | | date | [{value: 'gt', label: '大于'}, {value: 'gte', label: '大于等于'}, {value: 'lt', label: '小于'}, {value: 'lte', label: '小于等于'}, {value: 'between', label: '在...之间'}] | | datetime | [{value: 'gt', label: '大于'}, {value: 'gte', label: '大于等于'}, {value: 'lt', label: '小于'}, {value: 'lte', label: '小于等于'}, {value: 'between', label: '在...之间'}] | | time | [{value: 'gt', label: '大于'}, {value: 'gte', label: '大于等于'}, {value: 'lt', label: '小于'}, {value: 'lte', label: '小于等于'}, {value: 'between', label: '在...之间'}] | | number | [{value: 'gt', label: '大于'}, {value: 'gte', label: '大于等于'}, {value: 'lt', label: '小于'}, {value: 'lte', label: '小于等于'}, {value: 'between', label: '在...之间'}] | | string | [{value: 'contains', label: '包含'}, {value: 'notContains', label: '不包含'}, {value: 'equals', label: '等于'}, {value: 'notEquals', label: '不等于'}] | | multiSelect | [{value: 'contains', label: '包含'}, {value: 'notContains', label: '不包含'}] | | select | [{value: 'equals', label: '等于'}, {value: 'notEquals', label: '不等于'}] | | fieldCompare | [{value: 'equals', label: '等于'}, {value: 'notEquals', label: '不等于'}] | | nullCheck | [{value: 'exists', label: '存在'}, {value: 'notExists', label: '不存在'}] |

  2. [conditionCategories] CategorySetting[]:

    用于将条件选择框里的选项按照其分类进行分组,key对应 [conditionSettings] 数据里的category。

    例子:[{key: 'flight', name: '航班'}, {key: 'task', name: '任务'}]

    categorySettings1

  3. [nodes] 用于显示已保存了的条件数据,由 getConditionResult() 的方法获取:

    getConditionResult() 会返回 scriptnodes 两个对象,其中script是最后生成的逻辑表达式;nodes 是代表当前交互界面对应的数据,用户可以把这段json数据保存下来。
